Title: Viscous composition

Description:
TECHNICAL FIELD 
     The present invention relates to a viscous composition including cellulose fibers. 
     BACKGROUND ART 
     As a viscous composition, there are mentioned a cosmetic composition for use for various cosmetics and others; a gel-type composition for use for promotion of viscosity increase or for gelation; and further a spray composition for use for spray nebulization, etc. 
     Heretofore, for cream-type, gel-type, emulsion-type or liquid-type cosmetic materials, a composition is used wherein a polymer material or the like is mixed with a dispersant medium such as water, alcohol, oil or the like. The polymer material is used for the purpose of imparting shape retention performance (shape retention capability) for maintaining viscosity increase and dispersion stability, and for example, water-soluble cellulose derivatives such as methyl cellulose, carboxymethyl cellulose salt, etc.; synthetic polymers such as polyvinyl alcohol, polyvinyl pyrrolidone, carboxyvinyl polymer, polyethylene glycol, etc.; natural polymer polysaccharides such as quince seed, bee gum, xanthane gum, hyaluronic acid salt, etc. are used. Most of these polymer materials are soluble in water, and are therefore stringy and are not felt good to use, and many of them have poor salt tolerance. 
     In the background, a cosmetic composition not having the feeling in use specific to water-soluble polymer but excellent in dispersion stability is desired. For the cosmetic composition of the type, for example, a cosmetic composition which includes cellulose particles prepared through hydrolysis and physical grinding of natural cellulose without regeneration (Patent Reference 1) is proposed. This is a composition in which the fat fraction is lowered than in conventional cosmetic compositions and which can attain creamy or emulsion-like properties. However, since it contains coarse grains having a large grain size, the dispersiveness thereof is insufficient to cause a rough feel of the composition. 
     As a technique of highly dispersing cellulose, a method for producing microfibrillar cellulose by processing an aqueous suspension of pulp with a high-pressure homogenizer to grind it to a microfibril level t is proposed (Patent Reference 2). Since the high-degree dispersion of cellulose to be obtained according to the production method must be processed by the use of an extremely large quantity of energy and the degree of dispersion thereof is insufficient, it is impossible to erase the rough feel specific to the dispersion. Furthermore, the conventional microfibrillated cellulose dispersions are all white and nontransparent, and therefore have a problem in that they could not be applied to cosmetic materials required to be transparent. 
     To solve the problem, a cosmetic composition that includes cellulose microfibrillated in nanosize is proposed (Patent Reference 3). However, those described in the patent publications are still insufficient for solving the above-mentioned problems, as described below. 
     On the other hand, as a tackifier and a gelling agent, natural polymer compounds such as Jerangam, carrageenan, agar, xanthan gum, etc.; nonionic water-soluble celluloses such as methyl cellulose, hydroxylmethyl cellulose, etc.; ionic celluloses such as carboxymethyl cellulose, cationized cellulose, etc.; synthetic polymers such as polyvinyl alcohol, polyvinyl pyrrolidone, sodium polyacrylate, carboxyvinyl polymer, polyethylene glycol, etc.; water-swellable clay minerals such as smectite, etc are conventionally used. 
     However, since the above-mentioned natural polymer compounds are poorly soluble in water, heat treatment of water in the process of producing gel-type compositions is required and consequently have a problem of poor producibility. Additionally, there is another problem that when fragrance or the like is added thereto, a part of the added fragrance or the like may evaporate away. On the other hand, since the above-mentioned nonionic water-soluble celluloses have high solubility in water, heat treatment of water is not necessary. However, for obtaining gel-type compositions, there is a problem in that a large quantity of the water-soluble cellulose must be added. In addition, the above-mentioned synthetic polymers such as sodium polyacrylate, carboxyvinyl polymer and the like are troublesome in that a special attention must be paid thereto so as not to form unmixed-in lumps in dispersing and dissolving them and that they require pH control. It is disclosed that the above-mentioned xanthan gum is stringy and, in use for cosmetics and the like, it causes a sticky feeling (Non-Patent Reference 1). Most of these natural polymer compounds, water-soluble celluloses and synthetic polymers have many problems in point of the range of use and the designability thereof in that their viscosity greatly lowers depending on co-existing salts and they are stringy. 
     In the situation, a nasal gel using a carboxyvinyl polymer as the gelling agent therein has been proposed, and it is disclosed that the gel has been improved to prevent dripping and has an effect of promoting the absorbability of the pharmaceutical ingredient therein (Patent Reference 4). In addition, it is disclosed that cellulose particles downsized to a few 10 nm have high transparency and can show high performance of thickening, dispersion and emulsion stabilization and structure stabilization even when a small amount thereof is added (Patent Reference 5). However, those described in these patent references are still unsatisfactory for solving the above-mentioned problems, as described below. 
     In general, spray products are used as products in a broad field of hair-care products, skincare products, aromatic substances, detergents, various coating agents, agricultural chemicals and others. Many spray products are commercialized by charging a liquid composition in a spray apparatus. The properties necessary for spray products are that they can be sprayed by using ordinary spray containers under broad environmental condition (temperature, humidity, etc.); that the sprayed droplets could have a suitable size depending on the intended use and are free from spraying unevenness; and that they are also free from dripping when sprayed onto vertical faces or inclined faces. 
     Recently, a lot of sprayable gel-type compositions have been proposed (see Patent References 6 to 9). These sprayable gel-type compositions have excellent characteristics in that they are free from a trouble of dripping when they are sprayed on vertical faces or inclined faces. 
     For example, in Patent Reference 6, a gel-type mist cosmetic product using a clay mineral, smectite is proposed. In Patent Reference 7, a gel-type composition for spray, also using a clay mineral, hectorite is proposed. Since these clay minerals are in the form of extremely small particles, they can swell with water or with any other solvent and disperse thereinto to form a sol/gel. Since the dispersion of the clay mineral has thixotropy, when a pressure (force) on a certain level or more is given, it liquefies, while when released from the pressure (force), it immediately change into gels. Using the property specific to the clay mineral, the above-mentioned composition for spray may be combined with a spray container, to enable spraying the composition without the trouble by dripping. 
     In Patent Reference 8, an aerosol composition which is for mist-like spraying of an aqueous liquid concentrate having a high viscosity for uniform adhesion with no dripping is proposed. In the aqueous liquid concentrate, a cellulosic thickener and a crosslinked acrylic thickener are used. In case of these thickeners, stringiness is not shown even in a high viscosity and show high-level thixotropy. Therefore they can be excellent gel-type spray compositions. 
     In Patent Reference 9, a composition for spray agent, which includes cellulose fine particles having a mean degree of polymerization (DP) of 100 or less, a fraction of cellulose I-type crystal component of 0.1 or less, a fraction of cellulose II-type crystal component of 0.4 or less and a mean particle size of 2 μm or less, and a liquid dispersion medium, wherein the cellulose concentration is from 0.1 to 5.0% by weight and on the viscosity-shear stress curve of the composition, which is measured with a cone-plate type rotatory viscometer at 25° C. in a shear rate region including at least from 1×10 −3  S −1  to 1×10 2  S −1 , the maximum value of the viscosity (η max ) is η max ≧1×10 3  mPa·s. The cellulose fine particles used in the spray composition can be obtained through acid hydrolysis of natural cellulose or regenerated cellulose. The spray composition including the above-mentioned cellulose particles is transparent in an aqueous medium and have excellent properties in that its mother droplets can well fix on the sprayed surface with little spraying unevenness and the sprayed mother droplets are free from a trouble of dripping on vertical faces and inclined faces. However, those described in these patent publications are still unsatisfactory for solving the above-mentioned problems, as described below.

     SUMMARY OF THE INVENTION 
     Problems to be Solved by the Invention 
     Of the above-mentioned patent publications relating to cosmetic compositions, since one described in the newest the Patent Publication 3 includes nanoparticulated cellulose fine particles, it gives a good feel in use with neither sticky feeling nor rough feeling. However, since the production of the cellulose fine particles requires a large quantity of sulfuric acid, there are problems in view of the environmental load and the workability. In addition, since the dispersion of cellulose fine particles has poor salt tolerance, there is an another problem in that its application field is greatly limited. 
     As in the above, in conventional techniques, various problems that sufficient performance as materials for cosmetics cannot be obtained such as that the degree of dispersiveness is insufficient; the rough feeling of dispersions could not be overcome; and the salt tolerance of dispersions is poor and the application range thereof is therefore limited. 
     Of the Patent References 4 and 5 relating to conventional thickeners and gelling agents, those described in the Patent Reference 4 have difficulties in production such as that it requires pH control with a basic substance in their preparation and requires strong stirring for uniform mixing and dispersion of pharmaceutical ingredients in high-viscosity base material. The cellulose particles described in Patent Reference 5 have difficulties such that their viscosity lowers in the co-presence of an electrolyte such as salts or a high-concentration ionic surfactant and that, in addition, the cellulose particles settle out and could not take a form of dispersion as a recult. 
     Of the Patent References 6 to 8 relating to spray compositions, the dispersion of the spray compositions described in the Patent Reference 6 and the Patent Reference 7 are nontransparent owing to the clay minerals dispersed therein, and in addition, they are colored specifically to the clay minerals. Therefore, the spray compositions are problematic in that they could not be used for applications that require transparency. Another problem with them is that, when the sprayed coating film is dried, it often forms powder on the surface thereof. Still another problem is that, when an alcohol exists in the solvent, the clay mineral may aggregate to greatly worsen the spray properties (spraying performance). 
     In the spray composition of the Patent Reference 8, since the function of the thickener (especially, crosslinked acrylic thickener) worsens in the co-presence of an electrolyte or the like salt or an ionic substance, the viscosity of the composition greatly lowers. Consequently, in case where it is used as a spray composition that requires a viscosity, there is a problem that the functional additives (electrolyte, ionic substance, etc.) which can be incorporated therein are limited. 
     In the spray composition of Patent Reference 9, in case where an ionic substance such as an anionic surfactant, an inorganic salt, a carboxymethyl cellulose or the like is incorporated, even when the amount thereof added is small, the hydration of the cellulose particles would be inhibited to cause coagulation and precipitation of the particles. In general, various functional additives such as ionic substance and others are mixed in a spray composition. However, the cellulose fine particles described in the Patent Reference 9 are problematic in that the functional additives capable of being added thereto are limited for the reasons mentioned above. 
     As in the above, the sprayable gel compositions which is conventionally proposed in the art have, in summary, the following problems (1) and (2): 
     (1) The applicable use and object are limited, and when the sprayed coating film is dried, it may form a powder on the surface thereof. 
     (2) In the co-presence of an ionic substance, an electrolyte or the like, the viscosity greatly lowers and the compositions could not keep a gel state, or the thickener itself may aggregate or settle out. 
     In the situation as above, an object of the present invention is to provide a viscous composition which is useful as a cosmetic composition excellent in shape retention ability, dispersion stability and salt tolerance; to provide a viscous composition which is useful as a gel-type composition capable of maintaining the high viscosity thereof even in the co-presence of a salt, an ionic surfactant or the like; and to provide a viscous composition which is useful as a spray composition of which the viscosity does not lower even in the co-presence of a functional additive such as an electrolyte, an ionic substance or the like and which can therefore maintain a stable gel state and can be sprayed.

     BACKGROUND TO THE INVENTION 
     The inventors of the present invention made a series of studies for the purpose of finding out cellulose fibers useful for use in the above-mentioned cosmetics, thickeners and gelling agents, sprays, etc. Among them, the inventors made assiduous studies many times for obtaining a cosmetic composition excellent in shape retention ability, dispersion stability and salt tolerance. In the process of the studies, the inventors have reached fine cellulose fibers (A) having a maximum fiber diameter of 1000 nm or less and a number-average fiber diameter of from 2 to 100 nm, wherein the cellulose has a cellulose I-type crystal structure; the hydroxyl group at the C6-position of the glucose unit in the cellulose molecule is selectively oxidized and modified into an aldehyde group and a carboxyl group; and the amount of the carboxyl group is from 0.6 to 2.2 mmol/g. Using a dispersion prepared by dispersing the specific fine cellulose fibers in a liquid dispersion medium, water, the inventors have found that a viscous composition useful as a cosmetic composition excellent in shape retention ability, dispersion stability and salt tolerance can be obtained. 
     In addition, the inventors made assiduous studies further many times for obtaining a viscous composition especially useful as a gel-type composition capable of maintaining a high viscosity even in the co-presence of a salt, an ionic surfactant or the like. In the process of the studies, the inventors have specifically noted fine cellulose fibers having a maximum fiber diameter of 1000 nm or less and a number-average fiber diameter of from 2 to 150 nm, wherein the cellulose has a cellulose I-type crystal structure, the hydroxyl group at the C6-position of the glucose unit in the cellulose molecule is selectively oxidized and modified into an aldehyde group and a carboxyl group. With that, the inventors have reached a gel-type composition by combining the specific fine cellulose fibers, in which the amount of the aldehyde group is from 0.08 to 0.3 mmol/g and that of the carboxyl group is from 0.6 to 2.0 mmol/g (water-insoluble cellulose fibers) (A″), and a liquid dispersion medium, water. The inventors made experiments many times relating to the preferable content of the specific cellulose fibers in the gel-type composition, and have found that, when the content of the specific cellulose fibers falls within a range of from 0.3 to 5.0% by weight of the entire gel-type composition, the composition can attain the intended object. 
     Further, the inventors recalled use of the special fine cellulose fibers that the inventors had developed as the material for a spray composition as a type of the viscous composition for material for a spray composition. The fine cellulose fibers (A″) have a maximum fiber diameter of 1000 nm or less and a number-average fiber diameter of from 2 to 150 nm, and when it is dispersed in a dispersion medium, water, they form a transparent gel while maintaining flowability without forming flocculates of cellulose fibers therein. However, they are sprayed, they immediately liquefy owing to the spraying pressure, and can be well sprayed to a subject to coat it. In addition, the cellulose is in the form of surface-oxidized microtine fibers of a naturally-derived cellulose solid material having an I-type crystal structure; and shows features that the sprayed mother liquid droplets to coat the subject can again gel; its fixity is good; and it is free from spraying unevenness and from a trouble of dripping of the mother droplets thereof on vertical faces or inclines faces. Furthermore, the inventors have found that a part of the hydroxyl group of the cellulose (the hydroxyl group at the C6-position of the glucose unit in the cellulose molecule) is, through selective oxidation thereof, modified into a functional group such as a carboxyl group and an aldehyde group and the amount of the functional group is defined to fall within a specific range. Therefore, even when a small amount of the cellulose is added, the resulting composition can be highly thickened and can efficiently maintain the gel state thereof, and at the same time, even in the co-presence of an electrolyte or an ionic substance, the composition does not cause separation or water release and can well keep the gel state thereof having a high viscosity, and can therefore attain the intended object. 
     Effect of the Invention 
     As in the above, the viscous composition of the present invention includes the above-mentioned special cellulose fibers (A), (A′) or (A″). For use as a cosmetic composition, the cellulose fibers of the above component (A) are combined with water (B) and the functional additive (C) such as a water-releasing material or the like to give a cosmetic composition which is excellent in shape retention ability and dispersion stability and excellent in water tolerance to satisfy the properties and the performance which is necessary for cosmetics. Since the specific cellulose fibers (A) are extremely fine, the composition provides an excellent feeling in use for when application to skin, with neither sticky feeling nor rough feeling. In addition, the cosmetic composition is free from viscosity decrease even at a high temperature of 50° C. or more, and is excellent in temperature stability. 
     Furthermore, since the cellulose fibers in which the hydroxyl group at the C6 position of the glucose unit on the surface of the cellulose fibers is selectively oxidized into an aldehyde group and a carboxyl group are used therein, the cosmetic composition can easily provide surface smoothness which conventional cellulose fine particles could not provide, and is free from a feeling of stickiness which is specific to water-soluble polymers. In addition, the cosmetic composition containing salts here can be thickened and the dispersion stability thereof can be obtained which are difficult in the conventional cases containing cellulose fine particles and a water-soluble polymer and salt tolerance is to enhance salt tolerance is enhances as a result. 
     In case where the cellulose fibers of the component (A) are such that a part of the hydroxyl group of the cellulose fibers is oxidized with a co-oxidizing agent in the co-presence of an N-oxyl compound such as 2,2,6,6-tetramethylpiperidine (TEMPO) or the like, the cellulose fibers may be easily processed to give microfine fibers having a number-average fiber diameter of from 2 to 100 nm to facilitate the production of the cosmetic composition. 
     In case where the viscous composition of the present invention is used as a gel-type composition, the cellulose fibers (A′) of the above-mentioned special cellulose fibers are combined with (B) water. In the gel-type composition including the components, the content of the fine cellulose fibers (A′) falls within a range of from 0.3 to 5.0% by weight of the entire gel-type composition. Therefore, even in the co-presence of a salt, an ionic surfactant or the like, the composition can maintain the gel state thereof without separation or water release. In addition, the gel-type composition of the present invention is easy to use, since it is not stringy and is easily mixed with various types of functional additives. 
     In addition, since the gel-type composition can sufficiently keep the viscosity thereof even in high-temperature environments, it is usable, for example, for in-car applications to be used at high in-car temperatures of 70° C. or more (aromatic substances, deodorants, air refreshers, etc. for automobiles). On the other hand, since natural polysaccharide gelling agents such as gelatin, agarose and others undergo sol-gel transition at high temperatures and could not keep the viscosity as gel, they are unsuitable for such applications. 
     The gel-type composition including the specific cellulose fibers and water (liquid dispersion medium) is well miscible with functional additives such as inorganic salts, surfactants and the like, and can be widely favorably used as a gel substrate for toiletry goods such as aromatic substances, etc. 
     In the cellulose fibers of the component (A′), when a part of the hydroxyl group is oxidized with a co-oxidizing agent in the co-presence of an N-oxyl compound into a carboxyl group and an aldehyde group and when the amount to be used of the co-oxidizing agent and the time for oxidation are controlled, then the oxidized and modified functional groups may be controlled to fall within a specific range. Therefore the resulting gel-type composition can exhibit better results. 
     In case where the viscous composition of the present invention is used as a spray composition, the special cellulose fibers of (A″) are combined with (B) water. The spray composition including these components can maintain a stable gel state with time even if functional additives such as electrolytes, ionic substances and the like are contained. Consequently, various functional additives necessary for the use of the composition can be mixed in the composition with no trouble. The spray composition composed of the indispensable components alone is transparent and, when it is sprayed, it can be immediately liquefied owing to the spraying pressure, and can be well sprayed on a subject to coat it. The mother liquid droplets thus sprayed for coating can again gel and its fixity is good with little spraying unevenness, and the mother liquid droplets are free from a trouble of dripping on vertical faces or inclined faces. The coating film formed of the spray composition does not form a powder on the surface thereof, after drying. 
     In the spray composition, since the content of the special cellulose fibers is from 0.1 to 3.0% by weight, and the maximum value of the viscosity (η max ) of the composition, which is measured with a cone-plate type rotatory viscometer at 20° C. in a shear rate region including from 1×10 −3  S −1  to 1×10 3  S −1 , is η max ≧1×10 4  mPa·s, the composition enables good spray coating with no dripping. In addition, since the minimum value of the viscosity (η min ) of the composition is η min ≦1×10 2  mPa·s, the composition can be sprayed as fine mother liquid droplets with no spraying unevenness. 
     In case where the special cellulose fibers (A″) are oxidized with a co-oxidizing agent in the presence of an N-oxyl compound, the amount of the carboxyl group and the amount of the aldehyde group in the cellulose fibers can be readily controlled to fall within a suitable range, and better results can be obtained as the spray composition. 
     The spray atomizer charged with the spray composition can more effectively exhibit the effects which is specific to the spray composition of the present invention. 
    
    
     MODE FOR CARRYING OUT THE INVENTION 
     Next, the viscous composition of the present invention is described specifically in individual sections of the cosmetic composition, the gel-type composition and the spray composition. 
     [Cosmetic Composition] 
     The embodiment of the cosmetic composition is firstly described in detail. 
     The cosmetic composition of the present invention includes specific cellulose fibers (component A), water (component B) and a functional additive (component C). 
     The cosmetic composition of the present invention is characterized by using fine cellulose fibers (component A) that have a maximum fiber diameter of 1000 nm or less and a number-average fiber diameter of from 2 to 100 nm, wherein the cellulose has a cellulose I-type crystal structure, the hydroxyl group at the C6-position of the glucose unit in the cellulose molecule is selectively oxidized and modified into an aldehyde group and a carboxyl group, and the amount of the carboxyl group is from 0.6 to 2.2 mmol/g. This means that the cellulose fibers are surface-oxidized microfibrillated fibers of a naturally-derived cellulose solid material having an I-type crystal structure. Specifically, in a process of biosynthesis of natural cellulose, nanofibers called microfibrils are firstly formed almost unexceptionally, and these are multi-bundled to give a high-order solid structure. However, for attenuating the hydrogen bonding between the surfaces of the microfibrils, which serves as a locomotive for the strong aggregation force between these microfibrils, a part of the hydroxyl group is oxidized and converted into an aldehyde group and a carboxyl group. 
     In this connection, the fact the cellulose to constitute the specific cellulose fibers (component A) has an I-type crystal structure can be identified, for example, by the typical peaks appearing at two positions near 2θ=14 to 17° and near 2θ=22 to 23° in the diffraction profile in wide-angle X-ray diffractiometry thereof. 
     The specific cellulose fibers (component A) have a maximum fiber diameter of 1000 nm or less and a number-average fiber diameter of from 2 to 100 nm, and from the viewpoint of dispersion stability thereof, preferably having a number-average fiber diameter of from 3 to 80 nm. Specifically, when the number-average fiber diameter is less than 2 nm, then the fibers inherently dissolve in the dispersion medium, but on the contrary, when number-average fiber diameter is more than 100 nm, then the cellulose fibers would settle out and therefore could not express the functionality to be attained by incorporation of the cellulose fibers. Similarly, when the maximum fiber diameter is more than 1000 nm, the cellulose fibers would settle out. Therefore, the functionality to be attained by incorporation of the cellulose fibers cannot be obtained. 
     The number-average fiber diameter and the maximum fiber diameter of the specific cellulose fibers (component A) can be measured, for example, as follows: specifically, water is added to the cellulose fibers to prepare a mixture having a cellulose solid content of 1% by weight. This is dispersed, using an ultrasonic homogenizer, a high-pressure homogenizer, a blender having a power of revolution speed of at least 15,000 rpm or the like, and then freeze-dried to prepare a sample. This is observed with a scanning electronic microscope (SEM) or the like, and the number-average fiber diameter and the maximum diameter of the cellulose fibers can be measured and calculated by the obtained image. 
     In the specific cellulose fibers (component A), the hydroxyl group at the C6 position of the glucose unit in the cellulose molecule is selectively oxidized and modified into an aldehyde group and a carboxyl group, and the amount of the carboxyl group is from 0.6 to 2.2 mmol/g. Furthermore, from the viewpoint of the shape retention capability and the dispersion stability, the amount is especially preferably within a range of from 0.6 to 2.0 mmol/g. Specifically, when the amount of the carboxyl group is less than 0.6 mmol/g, then the dispersion stability of the cellulose fibers is poor and the fibers may settle out, but on the contrary, when the amount of the carboxyl group is more than 2.2 mmol/g, the water-solubility of the fibers may increase and the fibers may tend to give a sticky feeling. 
     The amount of the carboxyl group in the specific cellulose fibers (component A) may be measured, for example, through potentiometric titration. Namely, the cellulose fibers after drying are dispersed in water, and an aqueous 0.01 N sodium hydroxide solution is added thereto and fully stirred to disperse the cellulose fibers therein. Next, 0.1 N hydrochloric acid solution is added until the pH value of the resulting mixture could reach from 2.5 to 3.0. Then an aqueous 0.04 N sodium hydroxide solution is dropwise added thereto at a speed of 0.1 ml/min. From the difference between the neutralization point of the excess hydrochloric acid on the obtained pH curve and the neutralization point of the cellulose fibers-derived carboxyl group, the amount of the carboxyl group can be calculated. 
     The amount of the carboxyl group can be controlled by controlling the amount of the co-oxidizing agent to be added and the reaction time in the step of oxidation of the cellulose fibers, as described below. 
     In the specific cellulose fibers (component A) in the present invention, only the hydroxyl group at the C6 position of the glucose unit on the surfaces of the cellulose fibers is selectively oxidized into an aldehyde group and a carboxyl group. The matter as to whether or not only the hydroxyl group at the C6 position of the glucose unit on the surfaces of the cellulose fibers has been selectively oxidized into an aldehyde group and a carboxyl group can be confirmed on the  13 C-NMR chart of the cellulose fibers. Namely, the peak at 62 ppm, corresponding to the C6 position of the primary hydroxyl group of the glucose unit, which is confirmed in the  13 C-NMR chart of the cellulose before oxidization is lost after the oxidization reaction, and alternatively, a peak derived from the carboxyl group appears at 178 ppm. In that manner, the oxidization of only the C6-positioned hydroxyl group of the glucose unit into an aldehyde group and a carboxyl group can be confirmed.

     The cellulose fibers (component A) for use in the cosmetic composition of the present invention can be produced, for example, as follows. Namely, firstly, a natural cellulose of soft wood pulp or the like is dispersed in water to be a slurry, then sodium bromide, N-oxyradical catalyst are added thereto, and fully stirred to disperse and dissolve them. Next, a co-oxidizing agent such as an aqueous hypochlorous acid solution or the like is added thereto, and then while an aqueous 0.5 N sodium hydroxide solution is dropwise added thereto so as to make it have a pH of 10.0, the reaction is continued until no pH change could be seen. The slurry obtained through the above reaction is purified by washing with water and filtration to remove the unreacted starting material, the catalyst and others to obtain the intended product, aqueous dispersion of specific, surface-oxidized cellulose fibers (component A). In case where higher transparency is required for the cosmetic composition, the dispersion may be further processed with a disperser having a strong dispersing power such as a high-pressure homogenizer or the like to obtain a composition having a higher transparency. 
     The above-mentioned N-oxyradical catalyst includes, for example, 2,2,6,6-tetramethylpiperidino-oxyradical (TEMPO), 4-acetamide-TEMPO, etc. Adding a catalytic amount of the N-oxyradical catalyst is enough, and preferably, the compound is added to the aqueous reaction solution in an amount falling within a range of from 0.1 to 4 mmol/l, more preferably from 0.2 to 2 mmol/l. 
     The co-oxidizing agent includes, for example, hypohalogenous acids or their salts, halogenous acids or their salts, perhalic acids or their salts, hydrogen peroxide, perorganic acids, etc. One or more of these may be used here either singly or in combination. Above all, preferred are alkali metal hypohalites such as sodium hypochlorite, sodium hypobromite, etc. In case where sodium hypochlorite is used, preferably, the reaction is promoted in the presence of an alkali metal bromide such as sodium bromide or the like, from the viewpoint of the reaction speed. The amount of the alkali metal bromide to be added may be from about 1 to 40 molar times the amount of the N-oxyradical catalyst, preferably from about 10 to 20 molar times. 
     The cosmetic composition of the present invention can be produced by suitably incorporating the functional additives (component C) for use for cosmetics, namely, the functional additives such as oily material, surfactant, alcohol, functional ingredient and others, into the aqueous dispersion of cellulose fibers (component A) prepared in the manner as above, followed by mixing and processing them. For the mixing treatment, for example, various kneading machines such as vacuum homomixer, disperser, propeller mixer, kneader, etc., as well as various grinders, blender, homogenizer, ultrasonic homogenizer, colloid mill, pebble mill, bead mill grinder, high-pressure homogenizer, ultrahigh-pressure homogenizer, etc can be used. 
     The amount of the specific cellulose fibers (component A) in the cosmetic composition of the present invention may vary depending on the desired function. In general, it falls within a range of from 0.01 to 6.0% by weight, and from the viewpoint of the feeling in use, it is preferably within a range of from 0.1 to 2.0% by mass. The amount of the oily material, the surfactant or the functional ingredient may be suitably defined depending on the use of the cosmetic material. By changing the concentration of the cellulose fibers (component A), the amount of various ingredients, and the dispersion treatment condition in mixing, cosmetic compositions having desired properties can be obtained. 
     The cosmetic composition of the present invention, thus obtained, can be used, for example, for skincare cosmetics such as face lotion, emulsion, cold cream, vanishing cream, massage cream, emollient cream, cleansing cream, beauty essence, pack, foundation, sunscreen cosmetic, sun-tanning cosmetic, moisture cream, hand cream, skin-whitening emulsion, various lotions, etc.; hair-care cosmetics such as shampoo, rinse, hair conditioner, rinse-in shampoo, hair-styling agent (hair foam, gel-type hair dressing, etc.), hair treatment agent (hair cream, treatment lotion, etc.), hair dye, lotion-type hair-growing agent, hair tonic, etc.; cleaning agents such as hand cleaner, etc.; as well as pre-shaving lotion, after-shaving lotion, air freshener, dentifrice, ointment, adhesive patch, etc. 
     [Gel-Type Composition] 
     The gel-type composition is explained next. 
     The gel-type composition of the present invention includes the specific cellulose fibers (component A′) and water (component B). 
     In the gel-type composition of the present invention, the content of the specific cellulose fibers (component A′) is defined to be from 0.3 to 5.0% by weight of the entire gel-type composition, preferably from 0.5 to 3.0% by weight. Specifically, when the content of the component A′ falls within the above range, then the composition can keep high viscosity even in the co-presence of salts, ionic surfactants, etc. As opposed to this, when the content of the component A′ is less than 0.3% by mass, the composition could not be in a gel stage when functional additives are added thereto, but would be fluid. On the contrary, when the content of the component A′ is more than 5.0% by weight, then the composition is extremely highly viscous and could not be microfibrillated in the subsequent dispersion step. Therefore the composition could not be a macroscopically homogeneous gel-type composition, namely, the intended gel-type composition could not be substantially obtained. 
     The specific fine cellulose fibers (component A′) for use in the gel-type composition of the present invention are, like the fine cellulose fibers for use in the above-mentioned cosmetic composition, cellulose fibers in which the hydroxyl groups are partly oxidized into an aldehyde group and a carboxyl group, and which have a maximum fiber diameter of 1000 nm or less. However, the number-average fiber diameter of the cellulose fibers is from 2 to 150 nm, and preferably, the maximum fiber diameter thereof is 500 nm or less and the number-average fiber diameter thereof is from 2 to 100 nm, and more preferably, the maximum fiber diameter thereof is 30 nm or less and the number-average fiber diameter thereof is from 2 to 10 nm. When cellulose fibers of which the maximum fiber diameter is more than 1000 nm or the number-average fiber diameter is more than 150 nm are used, then the cellulose fibers may settle down and the composition could not be in the form of a gel with keeping flowability. 
     Analyzing the fibers to determine the maximum fiber diameter and the number-average fiber diameter thereof can be attained in the same manner as that described hereinabove in the section of the cosmetic composition. Namely, for example, the fibers can be analyzed as follows. Briefly, an aqueous fine cellulose dispersion having a solid fraction of from 0.05 to 0.1% by weight is prepared, then the dispersion is cast onto a hydrophilicated carbon film-coated grid to prepare a sample for transmission electronic microscopy (TEM). In case where the sample contains fibers having a large fiber diameter which is not included the scope of the present invention, the surface of the sample cast onto a glass plate may be observed with a scanning electronic microscope (SEM). Depending on the size of the constituent fibers, the microscopic observation may be attained at any of 5000-power, 10000-power or 50000-power magnifications. In the picture image, vertical and horizontal axes for any desired image size are simulated, and the sample and the observation condition (magnification, etc.) are so controlled that at least 20 fibers could cross the axes. After obtaining the sample picture image satisfying the condition, vertical and horizontal two axes are drawn at random in one image, and the fiber diameter of the fibers crossing each axis is visually read. In that manner, at least three non-overlapping surface images are taken with the electron microscope, and the value of the fiber diameter of the fibers each crossing the two axes is read (accordingly, the information of fiber diameter of at least 120 fibers=20 fibers×2×3 can be thereby obtained). Based on the data of the fiber diameter thus obtained in the manner as above, the maximum fiber diameter and the number-average fiber diameter are calculated. 
     Next, the amount of the carboxyl group and that of the aldehyde group in the specific cellulose fibers (component A′) for use in the present invention are described. In general, when the total amount of the carboxyl group and the aldehyde group existing in cellulose is large, then the fibers are preferred since it can be exist stably in the form of fine fibers having a finer fiber diameter. In the present invention, from the viewpoint that the composition can be thickened even with small added amount, the amount of the aldehyde group in the specific cellulose fibers (component A′) is defined to fall within a range of from 0.08 to 0.3 mmol/g and the amount of the carboxyl group therein is within a range of from 0.6 to 2.0 mmol/g; and preferably, the amount of the aldehyde group is within a range of from 0.10 to 0.25 mmol/g and the amount of the carboxyl group therein is within a range of from 0.8 to 1.6 mmol/g. Specifically, when the amount of the carboxyl group and the amount of the aldehyde group are defined each to fall within the above range, then the specific cellulose fibers (component A′) can stably exist in the gel with no aggregation and precipitation therein. 
     The desired amount of the carboxyl group and that of the aldehyde group can be controlled by controlling the amount of the co-oxidizing agent to be used in the step of oxidizing the cellulose fibers and the reaction time therein. 
     The amount of the carboxyl group can be measured according to the method mentioned below. The amount of the aldehyde group can be measured through potentiometric titration as follows. 
     [Measurement of Amount of Carboxyl Group] 
     Using a cellulose sample of which the dry weight has been measured accurately, 60 ml of a slurry having a concentration of from 0.5 to 1% by weight of the cellulose sample is prepared; its pH is controlled to be at about 2.5 with an aqueous 0.1 M hydrochloric acid solution added thereto; and then an aqueous 0.05 M sodium hydroxide solution is dropwise added thereto for measurement of the electric conductivity. The measurement is continued until the pH of the solution could reach about 11. From the amount of sodium hydroxide (V) consumed in the neutralization stage with a weak acid where the change of the electric conductivity is gentle, the amount 1 of the functional group (amount of carboxyl group) can be obtained according to the following formula (1).
 
[Numerical Formula 1]
 
Amount of Functional Group 1 (mmol/g)= V  (ml)×0.05/(mass of cellulose, g)  (1)
 
[Measurement of Amount of Aldehyde Group]
 
     The same cellulose sample as above is further oxidized in an aqueous 2% sodium hypochlorite solution, which has been controlled to have a pH of from 4 to 5 with acetic acid, for 48 hours at room temperature (25° C.), and the amount 2 of the functional group is determined according to the above formula (1). With that, the amount of the functional group added by this oxidation (amount of functional group 2−amount of functional group 1) is calculated to obtain the amount of the aldehyde group. 
     Introduction of the aldehyde group or the carboxyl group into the cellulose of the specific cellulose fibers can be confirmed as follows. Namely, water is completely removed from the sample and the sample is analyzed through attenuated total IR reflectiometry (ATR), in which the presence of carbonyl group-caused absorption (at around 1608 cm −1 ) and acid-type carboxyl group (COOH)-caused absorption (at around 1730 cm −1 ) is confirmed. 
     Next, the above-mentioned specific cellulose fibers (component A′) can be produced in the same manner as in the case of the above-mentioned cosmetic composition. More precisely, for example, the fibers can be produced in a process including (1) an oxidation step, (2) a purification step and (3) a dispersion step (microfibrillation step). The steps are described in order. 
     (1) Oxidation Step 
     A natural cellulose and an N-oxyl compound are dispersed in water (dispersion medium), then a co-oxidizing agent is added thereto and the reaction is started. During the reaction, an aqueous 0.5 M sodium hydroxide solution is dropwise added so as to keep the pH of the system to be from 10 to 11, and at the time when the pH change can be no more seen, the reaction is considered to have stopped. In this connection, the co-oxidizing agent is not a substance which directly oxidizes the cellulose hydroxyl group but a substance that oxidizes the N-oxyl compound serving as an oxidation catalyst. 
     The natural cellulose means a pure cellulose isolated from a biosynthetic system of cellulose such as a vegetable, animal or bacteria-produced gel or the like. More specifically, it includes cellulose isolated from cotton pulp such as soft wood pulp, hard wood pulp, cotton linter, cotton lint or the like, non-wood pulp such as wheat straw pulp, bagasse pulp, etc., or bacteria cellulose (BC), cellulose isolated from ascidian, cellulose isolated from sea weeds, etc. One or more of these may be used here either singly or in combination. Of those, preferred are cotton pulp such as soft wood pulp, hard wood pulp, cotton linter, cotton lint or the like, and non-wood pulp such as wheat straw pulp, bagasse pulp, etc. When the natural cellulose is specifically processed by beating so as to increase the surface area thereof, then the reaction efficiency thereof can be favorably increased and the producibility can be thereby enhanced. In case where the natural cellulose that has been isolated and purified and, without being dried (never dry), stored is used, the bundle of the microfibrils can be readily swollen. Therefore, the cellulose in the state is preferably used here as the reaction efficiency is enhanced and the number-average fiber diameter of the microfibrillated fibers can be downsized. 
     The dispersion medium for the natural cellulose in the above reaction is water, and the concentration of the natural cellulose in the aqueous reaction solution may be any one with no limitation thereon so far as it enables sufficient diffusion of the reagent (natural cellulose). In general, the concentration is at most about 5% relative to the weight of the aqueous reaction solution, but the reaction concentration can be increased by using an apparatus having a strong mechanical stirring force. 
     As the N-oxyl compound, for example, a compound having a nitroxy radical that is used as a general oxidizing catalyst is generally mentioned. The N-oxyl compound is preferably a water-soluble compound; and especially preferred is piperidinenitroxy oxyradical, more preferred is 2,2,6,6-tetramethylpiperidino-oxy radical (TEMPO) or 4-acetamide-TEMPO. Adding a catalytic amount of the N-oxyradical catalyst is enough, and preferably, the compound is added to the aqueous reaction solution in an amount falling within a range of from 0.1 to 4 mmol/l, more preferably from 0.2 to 2 mmol/l. 
     The co-oxidizing agent includes, for example, hypohalogenous acids or their salts, halogenous acids or their salts, perhalic acids or their salts, hydrogen peroxide, perorganic acids, etc. One or more of these may be used here either singly or in combination. Above all, preferred are alkali metal hypohalites such as sodium hypochlorite, sodium hypobromite, etc. In case where sodium hypochlorite is used, preferably, the reaction is promoted in the presence of an alkali metal bromide such as sodium bromide or the like, from the viewpoint of the reaction speed. The amount of the alkali metal bromide to be added may be from about 1 to 40 molar times, preferably from about 10 to 20 molar times, of the amount of the N-oxyradical catalyst. 
     Preferably, the pH of the aqueous reaction solution is kept within a range of from about 8 to 11. Although the temperature of the aqueous solution may be freely within a range of from about 4 to 40° C., the reaction may be attained at room temperature (25° C.) and the temperature control is not specifically needed. 
     For obtaining the desired amount of the carboxyl group and the desired amount of the aldehyde group, the oxidation degree is controlled by controlling the amount of the co-oxidizing agent to be added and the reaction time. In general, the reaction time may be from about 5 to 120 minutes, and the reaction could finish at longest within 240 minutes. 
     (2) Purification Step 
     Next, for the purpose of removing the unreacted co-oxidizing agent (hypochlorous acid, etc.) and various side products and others, the reaction product is purified. In this stage, the reaction product fibers are not broken and dispersed to the nanofiber unit. Therefore, the reaction product is purified according to an ordinary purification method of repeatedly washing it with water and filtering it to obtain an aqueous dispersion of high purity (99% by weight or more) reaction product fibers and water. 
     In the purification method of the purification step, any apparatus capable of attaining the intended object can be used, for example, according to a method of using centrifugal water removal (with, for example, a continuous decanter). Thus obtained, the aqueous dispersion of the reaction product fibers has, in the squeezed state thereof, a solid (cellulose) concentration of from about 10% by weight to 50% by weight. In consideration of the subsequent dispersion step, a higher concentration than 50% by weight is unfavorable since an extremely high level of energy would be needed for the dispersion. 
     (3) Dispersion Step (Microfibrillation Step) 
     The water-containing reaction product fibers obtained in the above purification step are dispersed in a dispersion medium. With the treatment, the viscosity of the system increases and a dispersion of microfibrillated cellulose fibers can be obtained. After that, the cellulose fiber dispersion is dried to obtain specific cellulose fibers (component A′). The cellulose fiber dispersion may be used directly without drying as it is in the gel-type composition with no problem. 
     As the dispersion medium for the specific cellulose fibers (component A′) obtained in the manner as above, water (component B) is used. 
     As a dispersing apparatus to be used in the dispersion step, an apparatus having a strong beating force, such as high-speed revolution homomixer, high-pressure homogenizer, ultrahigh-pressure homogenizer, ultrasonic disperser, beater, disc-type refiner, conical refiner, double disc-type refiner, grinder or the like is preferable since it enable more efficient and high-level downsizing to obtain the intended gel-type composition in an economically advantageous manner. As the dispersing apparatus, for example, a screw-type mixer, a paddle mixer, a disperser-type mixer, a turbine-type mixer or the like may also be used with no problem. 
     Regarding the drying method for the cellulose fiber dispersion, for example, when the dispersion medium is water, a spray-drying method, a freeze-drying method or the like is used. When the dispersion medium is a mixed solution of water and an organic solvent, a drying method with a drier, a spray-drying method with a spray drier, or the like can be used.

The functional additive (component C′) includes, for example, inorganic salts, organic salts, surfactants, oils, moisturizers, antiseptics, organic fine particles, inorganic fine particles, deodorants, fragrances, organic solvents, etc. One or more of these may be used here either singly or in combination.

     The deodorants and fragrances include, for example, D-limonene, decyl aldehyde, menthone, pulegone, eugenol, cinnamaldehyde, benzaldehyde, menthol, peppermint oil, lemon oil, orange oil, as well as deodorant effective ingredients extracted from various organs of vegetables (for example, oxalis, Korean houttynia, hemlock fir ( Tsuga sieboldii ), gingko, Japanese black pine, larch, Japanese red pine, empress tree, fortune tea olive, lilac, orange osmanthus (sweet tea), giant butterbur, tsuwabuki ( Farfugium japonicum ), forsythia, etc.) with water or hydrophilic organic solvent. One or more of these may be used here either singly or in combination. 
     The organic solvents include, for example, water-soluble alcohols (methanol, ethanol, isopropanol, isobutanoyl, sec-butanol, tert-butanol, methyl cellosolve, ethyl cellosolve, ethylene glycol, glycerin, etc.), ethers (ethylene glycol dimethyl ether, 1,4-dioxane, tetrahydrofuran, etc.), ketones (acetone, methyl ethyl ketone), N,N-dimethylformamide, N,N-dimethylacetamide, dimethyl sulfoxide, etc. One or more of these may be used here either singly or in combination. 
     Although the amount of the functional additive (component C′) is preferably one necessary for expressing the intended effect of the functional additive, it is not specifically defined. 
     The gel-type composition of the present invention can be obtained, for example, by suitably blending the above-mentioned specific cellulose fibers (component A′) and water (component B) and, if necessary, the functional additive (component C′) followed by mixing them. 
     For mixing the components, for example, various kneading machines such as vacuum homomixer, disperser, propeller mixer, kneader, etc.; various grinding machines, as well as blender, homogenizer, ultrasonic homogenizer, colloid mill, pebble mill, bead mill grinder, high-pressure homogenizer, ultrahigh-pressure homogenizer, etc can be used. 
     The viscosity of the gel-type composition of the present invention, thus obtained, is preferably at least 15 Pa·s, preferably within a range of from 30 to 150 Pa·s. 
     The viscosity can be measured, for example, using a BH-type viscometer (No. 4 rotor), etc. 
     In this connection, the amount of water (component B) in the gel-type composition is so controlled that content of the specific cellulose fibers (component A′) in the composition could be from 0.1 to 5.0% by weight of the entire composition. Specifically, in case where the gel-type composition of the present invention is composed of the specific cellulose fibers (component A′) and water (component B) alone, the mixing amount of water (component B) in the composition (95% by weight to 99.9% by weight) is obtained after subtracting the content of the specific cellulose fibers (component A′) (from 0.1 to 5.0% by weight) in the composition from the amount of the entire composition. On the other hand, in case where the gel-type composition of the present invention contains the functional additive (component C′) or the like in addition to the specific cellulose fibers (component A′) and water (component B), the mixing amount of water (component B) in the composition is obtained after subtracting the content of the specific cellulose fibers (component A′) (from 0.1 to 5.0% by weight) and the content of the functional additive (component C′) or the like in the composition from the amount of the entire composition. 
     [Spray Composition] 
     The spray composition is described next. 
     The spray composition of the present invention includes the following components (A″) and (B), in which the content of the cellulose fibers of the component (A″) is from 0.1 to 3.0% by weight, and the maximum value of the viscosity (η max ) of the composition, which is measured with a cone-plate type rotatory viscometer at 20° C. in a shear rate region including from 1×10 −3  S −1  to 1×10 3  S −1 , is η max ≧1×10 4  mPa·s, and the minimum value of the viscosity (η min ) is η min ≦1×10 2  mPa·s. 
     (A″) Cellulose fibers having a maximum fiber diameter of 1000 nm or less and a number-average fiber diameter of from 2 to 150 nm, wherein the cellulose has a cellulose I-type crystal structure, the hydroxyl group at the C6-position of the glucose unit in the cellulose molecule is selectively oxidized and modified into an aldehyde group and a carboxyl group, and the amount of the carboxyl group is from 0.6 to 2.0 mmol/g and the amount of the aldehyde group is from 0.05 to 0.3 mmol/l. 
     (B) Water. 
     The fine cellulose fibers of the above component (A″) are, like those in the above-mentioned cosmetic composition and gel-type composition, have a maximum fiber diameter of 1000 nm or less and a number-average fiber diameter of from 2 to 150 nm. Preferably, the maximum diameter is 500 nm or less, and the number-average fiber diameter is from 2 to 100 nm; more preferably, the maximum fiber diameter is 30 nm or less, and the number-average fiber diameter is from 2 to 10 nm. This is because when cellulose fibers of which the maximum fiber diameter is larger than 1000 nm and the number-average fiber diameter is larger than 150 nm are used, the cellulose fibers settle down and could not form a uniform gel-like composition. 
     In this connection, the cellulose fibers may be analyzed for determining the maximum fiber diameter and the number-average fiber diameter thereof in the same manner as those for the gel-like composition. Specifically, an aqueous fine cellulose dispersion having a solid fraction of from 0.05 to 0.1% by weight is prepared, then the dispersion is cast onto a hydrophilicated carbon film-coated grid to prepare a sample for transmission electronic microscopy (TEM). In case where the sample contains fibers having a large fiber diameter which is not included in the scope of the present invention, the surface of the sample cast onto a glass plate may be observed with a scanning electronic microscope (SEM), and the image may be analyzed. Depending on the size of the constituent fibers, the microscopic observation may be attained at any of 5000-power, 10000-power or 50000-power magnifications. In the picture image, vertical and horizontal axes for any desired image size are simulated, and the sample and the observation condition (magnification, etc.) are so controlled that at least 20 fibers could cross the axes. After the sample picture image satisfying the condition is obtained, vertical and horizontal two axes are drawn at random in one image, and the fiber diameter of the fibers crossing each axis is visually read. In that manner, at least three non-overlapping surface images are taken with the electron microscope, and the value of the fiber diameter of the fibers each crossing the two axes is read (accordingly, the information of fiber diameter of at least 120 fibers=20 fibers×2×3 can be thereby obtained). Based on the data of the fiber diameter thus obtained in the manner as above, the maximum fiber diameter and the number-average fiber diameter are calculated. 
     The cellulose to constitute the cellulose fibers of the component (A″) has a cellulose I-type crystal structure, and a part of the hydroxyl group of the cellulose (the hydroxyl group at the C6-position of the glucose unit in the cellulose molecule) is selectively oxidized into a carboxyl group and an aldehyde group. This means that the cellulose fibers of the component (A″) are surface-oxidized microfibrillated fibers of a naturally-derived cellulose solid material having an I-type crystal structure. Specifically, in a process of biosynthesis of natural cellulose, nanofibers called microfibrils are firstly formed almost unexceptionally, and these are multi-bundled to give a high-order solid structure. However, in the present invention, for attenuating the hydrogen bonding between the surfaces of the microfibrils, which serves as a locomotive for the strong aggregation force between these microfibrils, a part of the hydroxyl group is oxidized and converted into an aldehyde group and a carboxyl group. 
     In case where the cellulose fibers of the component (A″) are oxidized with a co-oxidizing agent in the presence of an N-oxyl compound, the amount of the carboxyl group and the amount of the aldehyde group in the cellulose fibers can be readily controlled to fall within a suitable range, and the spray composition of the type can exhibit better results. In this connection, the co-oxidizing agent is not a substance that directly oxidizes the cellulose hydroxyl group but a substance that oxidizes the N-oxyl compound serving as an oxidation catalyst. 
     In this connection, the cellulose to constitute the cellulose fibers of the component A″ has an I-type crystal structure, which can be identified by wide-angle X-ray diffractiometry thereof like in the above. Briefly, the cellulose can be identified by the typical peaks appearing at two positions near 2θ=14 to 17° and near 2θ=22 to 23° in the diffraction profile. Since the cellulose has an I-type crystal structure, and in the spray composition of the present invention, the cellulose fibers do not dissolve in water but exist as microscopically dispersing therein. Consequently, the spray composition enables not only fine fog drip spraying but also, when it is used as a face lotion and applied to a face, another effect of giving a silky feeling to the skin. 
     In addition, in the spray composition of the present invention, the cellulose constituting the cellulose fibers of the component (A″) has a carboxyl group in an amount of from 0.6 to 2.0 mmol/g, like that of the fine cellulose fibers (A′) for use in the gel-type composition mentioned above. However, in this, the cellulose has an aldehyde group in an amount of from 0.05 to 0.3 mmol/g. Especially preferably, the cellulose has a carboxyl group in an amount of from 0.8 to 1.8 mmol/g and an aldehyde group in an amount of from 0.08 to 0.25 mmol/g. Falling within the range, the fine cellulose fibers (A″) having such a small fiber diameter can stably exist in the gel without aggregating and settling out therein, and even when a small amount of the cellulose fibers of the type is in the composition, the composition can have a high viscosity and can efficiently keep the gel state thereof. 
     In this connection, the amount of the carboxyl group and the amount of the aldehyde group in the cellulose fibers can be determined in the same manner as those in the gel-type composition mentioned above. Namely, using a cellulose sample of which the dry weight has been measured accurately, 60 ml of a slurry having a concentration of from 0.5 to 1% by weight of the cellulose sample is prepared; its pH is controlled to be at about 2.5 with an aqueous 0.1 M hydrochloric acid solution added thereto; and then an aqueous 0.05 M sodium hydroxide solution is dropwise added thereto for measurement of the electric conductivity. The measurement is continued until the pH of the solution could reach about 11. From the amount of sodium hydroxide (V) consumed in the neutralization stage with a weak acid where the change of the electric conductivity is gentle, the amount of the functional group (a) can be obtained according to the following formula (2). The amount of the functional group (a) indicates the amount of the carboxyl group in the sample.
 
[Numerical Formula 2]
 
Amount of Functional Group (mmol/g)= V  (ml)×0.05/(mass of cellulose, g)  (2)
 
     Next, the same cellulose sample as above is further oxidized in an aqueous 2% sodium hypochlorite solution, which has been controlled to have a pH of from 4 to 5 with acetic acid, for 48 hours at room temperature. Then it is again neutralized according to the same method as above, and from the amount of sodium hydroxide (V) consumed for the neutralization, the amount of the functional group (b) is determined according to the above formula (2). The amount of the functional group added by the oxidation [(b)-(a)] indicates the amount of the aldehyde group in the sample. 
     Introduction of the carboxyl group and the aldehyde group into the cellulose of the cellulose fibers of the component (A″) can be confirmed as follows. Namely, water is completely removed from the sample, and the sample analyzed through attenuated total IR reflectiometry (ATR), in which the presence of carbonyl group-caused absorption (at around 1608 cm −1 ) is confirmed. In particular, the acid-type carboxyl group (COOH) shows the absorption at 1730 cm −1 . 
     Next, the cellulose fibers of component (A″) can be produced in the same manner as in the case of the above-mentioned cosmetic composition and gel-type composition. Specifically, the fibers can be produced in a process including (1) an oxidation step, (2) a purification step and (3) a dispersion step (microfibrillation step). The steps are described in order. 
     (1) Oxidation Step 
     A dispersion of a natural cellulose in water for use in the oxidation step is firstly prepared. In this connection, the natural cellulose means a pure cellulose isolated from a biosynthetic system of cellulose such as a vegetable, animal or bacteria-produced gel or the like. More specifically, it includes cellulose isolated from cotton pulp such as soft wood pulp, hard wood pulp, cotton linter, cotton lint or the like, non-wood pulp such as wheat straw pulp, bagasse pulp, etc., or bacteria cellulose (BC), cellulose isolated from ascidian, cellulose isolated from sea weeds, etc. Of those, preferable ones for the cotton fibers for use in the present invention are cotton pulp such as soft wood pulp, hard wood pulp, cotton linter, cotton lint or the like, and non-wood pulp such as wheat straw pulp, bagasse pulp, etc. When the natural cellulose is specifically processed by beating so as to increase the surface area thereof, then the reaction efficiency thereof can be favorably increased and the producibility can be thereby enhanced. In case where the natural cellulose that has been isolated and purified and, without drying (never drying), stored is used, since the bundle of the microfibrils can be readily swollen, the cellulose in the state is preferably used here as the reaction efficiency is enhanced and the number-average fiber diameter of the microfibrillated fibers can be downsized. 
     Next, the cellulose fibers are oxidized, for example, with a co-oxidizing agent in the presence of an N-oxyl compound. 
     As the N-oxyl compound, herein usable is a compound having a nitroxy radical that is generally used as an oxidation catalyst. Above all, the N-oxyl compound for use in the present invention is a water-soluble compound. Especially preferred is piperidinenitroxy oxyradical, more preferred is TEMPO (2,2,6,6-tetramethylpiperidino-oxy radical) or 4-acetamide-TEMPO. Adding a catalytic amount of the N-oxyradical catalyst is enough, and preferably, the compound is added to the aqueous reaction solution in an amount falling within a range of from 0.1 to 4 mmol/l, more preferably from 0.2 to 2 mmol/l. 
     The co-oxidizing agent includes, for example, hypohalogenous acids or their salts, halogenous acids or their salts, perhalic acids or their salts, hydrogen peroxide, perorganic acids, etc. Preferred are alkali metal hypohalites such as sodium hypochlorite, sodium hypobromite, etc. In case where sodium hypochlorite is used, preferably, the reaction is promoted in the presence of an alkali metal bromide such as sodium bromide or the like, from the viewpoint of the reaction speed. The amount of the alkali metal bromide to be added may be from about 1 to 40 molar times the amount of the N-oxyradical catalyst, preferably from about 10 to 20 molar times. 
     Preferably, the pH of the aqueous reaction solution is kept within a range of from about 8 to 11. The temperature of the aqueous solution may be freely within a range of from about 4 to 40° C. and the reaction may be attained at room temperature and the temperature control is not specifically needed. 
     For obtaining the desired amount of the carboxyl group and the desired amount of the aldehyde group, the oxidation degree is controlled by controlling the amount of the co-oxidizing agent to be added and the reaction time. In general, the reaction time may be from about 5 to 120 minutes, and the reaction could finish at longest within 240 minutes. 
     (2) Purification Step 
     Next, for the fibers after the oxidation step (reaction product fibers) are purified. The reaction step is for removing the unreacted hypochlorous acid and various side products and others from the reaction product fibers to thereby purify the fibers. In this stage, the reaction product fibers are not broken and dispersed to the nanofiber unit, and is purified according to an ordinary purification method of repeatedly washing it with water and filtering it to obtain an aqueous dispersion of the reaction product fibers having a high purity (at least 99% by weight) and water. In the purification method of the purification step, any apparatus capable of attaining the intended object can be used, for example, according to a method of using centrifugal water removal (with, for example, a continuous decanter). Thus obtained, the aqueous dispersion of the reaction product fibers has, in the squeezed state thereof, a solid (cellulose) concentration of from about 10% by weight to 50% by weight. In consideration of the subsequent dispersion step of dispersing the fibers into nanofibers, a higher concentration than 50% by weight is unfavorable since an extremely high level of energy would be needed for the dispersion. 
     (3) Dispersion Step (Microfibrillation Step) 
     The reaction product fibers obtained after the above purification step are processed in a dispersion step (microfibrillation step). The dispersion (microfibrillation) of the reaction product fibers in the dispersion step depends on the degree of the reaction in the reaction product fibers (degree of conversion into the aldehyde group and the carboxyl group). Regarding the reaction product fibers in which the reaction has been appropriately proceeded, those after the purification step (aqueous dispersion) may be processed with general-purpose dispersing machine, for example, a screw-type mixer, a paddle mixer, a disperser-type mixer, a turbine-type mixer or the like, to obtain the intended dispersion. In the stage of dispersion treatment (microfibrillation treatment) of the reaction product fibers, if desired, a part or all of water (dispersion medium) of the above-mentioned component (B) and the functional additives may be added during the dispersion treatment. As the dispersing apparatus to be used in the dispersion step, an apparatus having a strong beating force, such as high-speed revolution homomixer, high-pressure homogenizer, ultrahigh-pressure homogenizer, ultrasonic disperser, beater, disc-type refiner, conical refiner, double disc-type refiner, grinder or the like is preferable since it enables more efficient and high-level downsizing to give the intended gel-type composition having a desired fiber diameter range in an economically advantageous manner. 
     As the dispersion medium for the cellulose fibers of the component (A″) obtained in the manner as above, water [component (B)] is used. 
     The optical functional additive [component (C″)] to be used along with the above-mentioned component (A″) and component (B) could cover a broader range than that of the additives used in the cosmetic composition. For example, it includes electrodes, ionic substances, surfactants, oils, moisturizers, organic fine particles, inorganic fine particles, antiseptics, deodorants, fragrances, organic solvents, etc. In particular, even when an electrolyte or an ionic substance (including an ionic surfactant) is incorporated in the spray composition of the present invention, the composition still has a high viscosity and shows a gel state to keep the gel state thereof not providing separation or water release. Therefore, the spray composition of the present invention exhibits excellent performance for those that need such functional additives to be incorporated therein. 
     The electrolytes and ionic substances include those capable of dissolving or dispersing in a dispersion medium such as water, for example, salts of a hydrogen halide, sulfuric acid, carbonic acid, an organic acid having at least one carboxyl group in the molecule or the like with an alkali metal, an alkaline earth metal, a transition metal or the like, such as sodium chloride, sodium edetate, sodium ascorbate, sulfonic acid-type surfactants such as sodium alkylsulfosuccinates, sodium alkylsulfonates, alkylsulfate ester salts, polyoxyethylene alkylsulfate ester salts, alkylbenzenesulfonate salts, etc.; phosphate-type surfactants such as polyoxyethylene alkylphosphate esters, etc.

     The antiseptics include, for example, methylparaben, ethylparaben, etc. 
     The deodorants and fragrances include, for example, D-limonene, decyl aldehyde, menthone, pulegone, eugenol, cinnamaldehyde, benzaldehyde, menthol, peppermint oil, lemon oil, orange oil, as well as deodorant effective ingredients extracted from various organs of vegetables (for example, deodorant effective ingredients extracted from oxalis, Korean houttynia, hemlock fir ( Tsuga sieboldii ), gingko, Japanese black pine, larch, Japanese red pine, empress tree, fortune tea olive, lilac, orange osmanthus (sweet tea), giant butterbur, tsuwabuki ( Farfugium japonicum ), forsythia or the like, with water or hydrophilic organic solvent), etc. One or more of these may be used here either singly or in combination.

     The functional additive [component (C″)] may be used here either singly or as a mixture of two or more different types of the compound, depending on the utilization field and the necessary performance of the spray composition of the present invention. The amount thereof may be within a suitable range depending on the necessary performance thereof. 
     The spray composition of the present invention can be prepared by dispersing the components of the above-mentioned components (A″) and (B) [and optionally the component (C″) and others], with using various types of dispersing machines. The dispersing machines may be the same as those used in preparing the cellulose fibers of the component (A″). As described above, water (dispersion medium) of the component (B) and the functional additive of the component (C″) may be added in preparing the cellulose fibers of the component (A″) (through microfibrillation). However, after preparation of the cellulose fibers of the component (A″), water (component B) and the functional additive (component C″) may be added thereto, and then dispersed with the above-mentioned dispersing machine. Since the cellulose fibers of the component (A″) serve also as an emulsion stabilizer, the cellulose fiber dispersion previously prepared may be mixed with an oil, if added thereto, according to an ordinary method of preparing an O/W emulsion. In this case, a nonionic surfactant or the like serving as an emulsion stabilizer may be additionally used, and the amount of the cellulose fibers may be determined in consideration of the emulsion stability and the sprayability of the composition. 
     The viscosity of the spray composition of the present invention and the content of the cellulose fibers of the component (A″) in the composition are defined to fall within a specific range from the viewpoint of the size of the mother liquid droplets thereof. Specifically, in the present invention, the content of the cellulose fibers of the component (A″) is from 0.1 to 3.0% by weight, and the maximum value of the viscosity (η max ) of the composition, which is measured with a cone-plate type rotatory viscometer at 20° C. in a shear rate region including from 1×10 −3  S −1  to 1×10 3  S −1 , is η max ≧1×10 4  mPa·s, which enables the composition show good spray coating with no dripping. In addition, since the minimum value of the viscosity (η min ) of the composition is η min ≦1×10 2  mPa·s, the composition can be sprayed as fine mother liquid droplets with no spraying unevenness. Contrary to this, a low-viscosity composition of which the value of η max  is lower than 1×10 4  mPa·s could not be expected to prevent the dripping in spraying, and when the value of η min  is larger than 1×10 2  mPa·s, then the mother liquid droplets would be large to cause spray unevenness. In case where the coating density in spraying is relatively low, the composition can be fully expected to prevent dripping so far as it satisfies η max ≧1×10 4  mPa·s. However, in case of thick spraying, the composition could not still prevent dripping even though satisfying η max ≧1×10 4  mPa·s, and consequently, for preventing dripping in any and every spraying condition, the spray composition of the present invention preferably satisfies η max ≧5×10 4  mPa·s in order that the composition can sufficiently exhibit the effect thereof. Also in spraying at an ordinary density, there may not occur spray unevenness when the composition satisfies η min ≧1×10 2  mPa·s. However, in case of extremely thin and uniform spraying, the composition preferably satisfies η min ≧5×10 1  mPa·s. For enabling stable spraying with the spray composition of the present invention, the value of η max  of the composition is preferably not larger than 10 9  mPa·s. 
     The spray composition of the present invention has high thixotropy. Therefore, when it is sprayed, its viscosity may lower for good spraying, and in addition, after spraying, the viscosity of the coating layer could be immediately restored on the coating surface to prevent dripping from the coated surface. Further, since the viscosity of the spray composition of the present invention does not lower even at a high temperature of 50° C. or higher, the composition is excellent in temperature stability. Consequently, the composition is free from a sticky feeling specific to water-soluble polymers and another excellent property thereof is that the composition can well spread after sprayed. 
     The spray atomizer to be charged with the spray composition of the present invention may be any one capable of being readily charged with the composition and capable of acting as an atomizer for spraying the composition. However, in consideration of the general versatility and the high accuracy thereof, the atomizer is preferably any of the following embodiments (1) to (3). Specifically, the spray atomizer is charged with the spray composition inside it. 
     (1) Dispenser-Type Atomizer Equipped with an Atomizable Pump-Type Nozzle: 
     The atomizer of the type can atomize the spray under atmospheric pressure, without requiring any pressure gas, and the vessel structure thereof is relatively simple and is highly safe. The atomizer of the type is suitable for mobile ones. The structure includes a push pump-type nozzle equipped with a suction tube, and a screw-type vessel that fixes the nozzle and is charged with the composition. The dispenser-type atomizer includes any and every modified one in which the structure of the pump-type nozzle is modified for increasing the atomizing performance. The atomizing performance depends on the orifice size of the jet nozzle and on the dose per one push. These conditions may be suitably selected depending on the intended object. 
     (2) Trigger-Type Atomizer 
     The trigger-type atomizer is an atomizer for house cleaners, cloth starches, kitchen cleaners, etc., and includes a pistol-type trigger spraying unit fitted to the mouth of the vessel body to be filled with the composition. The atomizer of the type enables spraying under atmospheric pressure and is very popular for liquid atomizers. The trigger-type atomizer as referred to herein includes any and every modified one in which a part of the trigger-type spray atomizer is modified for enhancing the atomizing performance. 
     (3) Aerosol-Type Atomizer 
     By filling a propellant in the container thereof, the aerosol-type atomizer enables continuous atomization or continuous foam formation that could not be realized by the above-mentioned two atomizers. The aerosol-type atomizer as referred to herein includes any and every modified one in which a part of the injector unit of the aerosol-type container is modified. In general, the atomizer of the type enables finer atomization in comparison with the above-mentioned two atomizers to be handled under atmospheric pressure. As the propellant to be used for aerosol atomization, dimethyl ether, liquefied petroleum gas, carbon dioxide, nitrogen gas, argon gas, air, oxygen gas, Freon gas, etc are mentioned. One or more of these may be used here either singly or in combination. 
     In case of using any of these atomizers, the spray composition of the present invention is used as the mother liquid therein, whereby the content in the atomizer can be in the form of a gel. Inside the container of those atomizers, the mother liquid does not flow and the spray atomizers enables atomization in all directions. In an extreme case, the atomizers enable atomization even when turned upside down, and can therefore favorably function as spraying devices. 
     EXAMPLES 
     Next, examples of the cosmetic composition, the gel-type composition and the spray composition are described below in separate sections. 
     [Examples of Cosmetic Composition] 
     Examples of the cosmetic composition along with Comparative Examples are firstly described. However, the present invention (cosmetic composition) should not be limited to these Examples. 
     Prior to Examples and Comparative Examples, cellulose fibers and cellulose fine particles were prepared as follows. 
     [Production of Cellulose Fibers T1] 
     To 2 g (dry weight) of softwood pulp, 150 ml of water, 0.025 g of sodium bromide and 0.025 g of TEMPO (N-oxyradical catalyst) were added and well stirred and dispersed, and then an aqueous 13% by weight sodium hypochlorite solution (co-oxidizing agent) was added thereto in such a manner that the amount of sodium hypochlorite could be 5.4 mmol per gram of pulp, and while an aqueous 0.5 N sodium hydroxide solution was dropwise added thereto so as to keep the pH of the system at from 10 to 11, the reaction was continued until no pH change could be seen (reaction time: 120 minutes). After the reaction, this was neutralized with 0.1 N hydrochloric acid added thereto, and then purified by repletion of filtering and washing with water, thereby giving surface-oxidized cellulose fibers T1. 
     [Production of Cellulose Fibers T2 to T3, H1 to H2] 
     Other cellulose fibers were produced in the same manner as the production for the cellulose fibers T1 except that the amount of the aqueous sodium hypochlorite solution to be added and the reaction time were changed as in Table 1 below. 
     [Production of Cellulose Fibers H3] 
     Soft wood pulp was immersed overnight in an aqueous 18% sodium hydroxide solution to prepare mercerized cellulose in which the cellulose I-type crystal structure was changed to a cellulose II-type crystal structure, and was used here in place of soft wood pulp, and reacted under the same condition as that for the cellulose fibers T1. The cellulose fibers H3 dissolved during the reaction, and at the end of the reaction, they gave a uniform aqueous solution. The obtained aqueous solution was neutralized to have a pH of from 7 to 8, with aqueous 0.1 N hydrochloric acid solution added thereto, and then left in running water for 10 days through a dialysis cellulose membrane (Spectra/ProCE, fractionation molecular weight, 500) to remove the remaining salts, the unreacted materials and the catalyst. The obtained aqueous solution was freeze-dried to give a powder of cellulose fibers H3. 
                         TABLE 1                      Cellulose Fibers                             for Examples   for Comparative Examples                                             T1   T2   T3   H1   H2   H3                                                 Amount of aqueous    5.4   4.1   12.5   3.4   20.4   25.6       sodium hypochlorite                                solution (mmol/g)                               Reaction time (min)   120   60   120   60   180   120       Amount of carboxyl    1.00   0.75   1.98   0.54   2.35   5.45       group (mmol/g)                               Amount of aldehyde    0.18   0.25   0.05   0.32   0.02   0.00       group (mmol/g)                               Maximum fiber    10   12   10   35   8   —       diameter (nm)                               Number-average fiber    7   7   6   15   6   —       diameter (nm)                    
[Production of Cellulose Fine Particles H4]
 
     According to Example 1 described in JP-A 2000-26229, low-crystalline cellulose fine particles were produced. Specifically, wood pulp having a mean degree of polymerization (DP) of 760 was dissolved in an aqueous 60 wt. % sulfuric acid solution at −5° C. in such a manner that the cellulose concentration could be 4% by weight, to prepare a cellulose dope. The cellulose dope was poured into water (5° C.) in an amount of 2.5 times by weight of the dope with stirring, thereby preparing a suspension of cellulose flocs. After heating up to 80° C., the suspension was hydrolyzed for 10 minutes, and then fully washed with water and water was removed under reduced pressure repeatedly many times until the pH of the wash waste could reach 4 or more to prepare a semitransparent white paste of pasty cellulose fine particles having a cellulose concentration of 6% by weight. The paste was diluted with water to have a cellulose concentration of 5% by weight, and stirred with a blender at a revolution speed of at least 15000 rpm for 5 minutes to give a semitransparent white paste containing low-crystalline cellulose fine particles H4. 
     The thus-obtained cellulose fibers and cellulose fine particles were analyzed for the following items, according to the criteria mentioned below. The results are shown in the above Table 1. 
     [Number-Average Fiber Diameter, Maximum Fiber Diameter] 
     Water was added to the cellulose fibers so that the cellulose solid content could be 1% by weight. It was dispersed, using an ultrahigh-pressure homogenizer (Mizuho Industry&#39;s Microfluidizer M-110EH), and then freeze-dried to prepare a sample, followed by observation with a scanning electron microscope (SEM) (JEOL&#39;s JSM-6380LV). Based on the image (magnification: 10000) thereof, the number-average fiber diameter and the maximum fiber diameter of the cellulose fibers were measured. 
     [Amount of Carboxyl Group] 
     The amount of the carboxyl group in the surface of the cellulose fibers were quantified through potentiometric titration. Specifically, 0.3 g of the dried cellulose fibers were dispersed in 55 ml of water, then 5 ml of an aqueous 0.01 N sodium hydroxide solution was added thereto and well stirred to prepare a dispersion of the cellulose fibers. Next, 0.1 N hydrochloric acid solution was added thereto until the pH of the dispersion could be from 2.5 to 3.0, and then an aqueous 0.04 N sodium hydroxide solution was dropwise added thereto at a speed of 0.1 ml/min. On the obtained pH curve, the amount of the carboxyl group was calculated from the difference between the point of neutralization of the excessive hydrochloric acid and the point of neutralization of the cellulose fibers-derived carboxyl group. 
     [Amount of Aldehyde Group] 
     The amount of the aldehyde group in the surface of the cellulose fibers were quantified according to the following method. Specifically, the sample was dispersed in water, and using sodium chlorite under an acid condition with acetic acid, the aldehyde group in the sample was completely oxidized into a carboxyl group, and the amount of the carboxyl group in the resulting sample was measured. The difference between the amount of the carboxyl group in the oxidized sample and that in the sample before oxidation indicates the amount of the aldehyde group in the sample. 
     [Confirmation on  13 C-NMR Chart] 
     As to whether or not the hydroxyl group alone at the C6-position in the glucose unit in the surface of the cellulose fibers was selectively oxidized into a carboxyl group, the sample was confirmed on the  13 C-NMR chart thereof. Specifically, the peak at 62 ppm corresponding to the C6-position of the primary hydroxyl group of the glucose unit, which is confirmed on the  13 C-NMR chart of the cellulose before oxidation, disappeared after the oxidation. Alternatively, a peak derived from the carboxyl group appeared at 178 ppm. From this, it was confirmed that, in the cellulose fibers T1 to T3, the C6-position hydroxyl group alone of the glucose unit was oxidized into an aldehyde group and a carboxyl group. 
     Next, using the cellulose fibers, cosmetic composition of Examples and Comparative Examples were produced. 
     Example 1A 
     As shown in Table 2 below, the cellulose fibers T3 in an amount of 1.0% by weight as the solid content thereof, the surfactant A (disodium lauryl polyoxyethylenesulfosuccinate) in an amount of 10% by weight and water in an amount of 89% by weight were mixed, and in vacuum, stirred at a revolution speed of 15,000 rpm or more for 10 minutes to produce a cosmetic composition. 
     Examples 2A, 3A, Comparative Examples 1A to 4A 
     Cosmetic compositions were produced in the same manner as in Example 1A except that the constituent components and their amount were changed as in Table 2 below.

     Thus obtained, the cosmetic compositions of Examples 1A to 3A and Comparative Examples 1A to 4A were evaluated for the properties thereof according to the criteria mentioned below. The results are shown in the above Table 2. 
     [Viscosity] 
     The viscosity of each cosmetic composition was measured with a BH-type viscometer (Rotor No. 4; number of revolutions, 2.5 rpm; 3 minutes, 25° C.). 
     [Dispersion Stability] 
     The change with time of the homogeneity of each cosmetic composition after mixing was investigated to evaluate the dispersion stability of the composition. Briefly, each cosmetic composition was left in a closed environment at 40° C. for 10 days, and checked for the condition thereof. 
     From the results in the above Table 2, it is known that the compositions of Examples had a high viscosity and were excellent in dispersion stability. In addition, it is confirmed that the compositions of Examples were kept stable for 2 months or more in evaluation of the dispersion stability thereof. 
     As opposed to these, the composition of Comparative Example 1A using the cellulose fibers H1 had a low viscosity and became nonhomogeneous in dispersion stability evaluation and was poor in dispersion stability. The composition of Comparative Example 2A using the cellulose fibers H2 had a high viscosity but was poor in dispersion stability. The composition of Comparative Example 3A using the cellulose fibers H3 had an extremely low viscosity; and the composition of Comparative Example 4A using the cellulose fine particles H4 had a low viscosity and separated and was poor in dispersion stability. 
     Example 1B 
     Water was added to the cellulose fibers T3 so that the cellulose solid content could be 1% by weight. This was processed one time with a high-pressure disperse (Sugino Machine&#39;s Ultimizer HJP-25003, operation pressure 150 MPa) to prepare a transparent gel. Next, as shown in Table 3 below, 30 g of polyoxyethylene glyceryl isostearate, 30 g of silicone oil A (Shin-Etsu Chemical&#39;s KF96-100CS) and 30 g of squalane were added to 10 g of the gel, and mixed using a homomixer (Primix&#39;s T.K. Robomix, 8,000 rpm×1 min) to produce a cosmetic composition. 
     Example 2B 
     A cosmetic composition was produced in the same manner as in Example 1B, except that silicone oil B (Shin-Etsu Chemical&#39;s KF995) was used in place of the silicone oil A in Example 1B, as shown in Table 3 below. 
     Comparative Example 1B 
     A cosmetic composition was produced in the same manner as in Example 1B, except that water was used in place of the gel in Example 1B, as shown in Table 3 below. 
     Comparative Example 2B 
     A cosmetic composition was produced in the same manner as in Example 2B, except that water was used in place of the gel in Example 2B, as shown in Table 3 below.

     Thus obtained, the cosmetic compositions of Examples 1B and 2B and Comparative Examples 1B and 2B were evaluated for the properties thereof according to the criteria mentioned below. The results are shown in the above Table 3. 
     [Viscosity] 
     The viscosity was evaluated according to the same criteria as above. 
     [Sticky Feeling] 
     Each cosmetic composition was applied on the upper arm of each of randomly-selected 10 panelists. The composition was evaluated in three stages of (A) not sticky, (B) sticky, and (C) extremely sticky. The samples with which at least 8 panelists gave (A) were ranked as “◯”; from 5 to 7 panelists as “◯”; from 2 to 4 panelists as “Δ”; and at most 1 panelist as “x”. 
     [Rough Feeling] 
     Each cosmetic composition was applied on the upper arm of each of randomly-selected 10 panelists. The composition was evaluated in three stages of (A) extremely smooth, (B) somewhat rough, and (C) extremely rough. The samples with which at least 8 panelists gave (A) were ranked as “⊚”; from 5 to 7 panelists as “◯”; from 2 to 4 panelists as “Δ”; and at most 1 panelist as “x”. 
     [Dispersion Stability] 
     The compositions were evaluated according to the same criteria as above. 
     From the results in the above Table 3, it is known that the compositions of Examples 1B and 2B had a high viscosity and were excellent in dispersion stability, and had good results in evaluation of sticky feeling and rough feeling. In addition, it is confirmed that the compositions of Examples 1B and 2B were good in evaluation of dispersion stability, as kept almost stable for 2 months or more. 
     As opposed to these, the composition of Comparative Example 1B not containing the cellulose fibers T3-containing gel had a lower viscosity than that of the compositions of Examples, had a sticky feeling and was poor in evaluation of dispersion stability. The composition of Comparative Example 2B not containing the cellulose fibers T3-containing gel was good in point of dispersion stability, but had a low viscosity and had a sticky feeling. 
     Example 1C 
     As shown in Table 4 below, the cellulose fibers T1 in an amount of 1.0% by weight as the solid content thereof, liquid paraffin in an amount of 20% by weight and glycerin in an amount of 5% by weight were added and dispersed using a homomixer (Primix&#39;s T.K. Robomix, 12,000 rpm×10 min) to produce a cosmetic composition. 
     Examples 2C to 3C 
     Cosmetic compositions were produced in the same manner as in Example 1C, except that the cellulose fibers T2 and T3, respectively, were used in place of the cellulose fibers T1 in Example 1C, as shown in Table 4 below. 
     Comparative Example 1C 
     A cosmetic composition was produced in the same manner as in Example 1C, except that the cellulose fibers T1 in Example 1C were not used but water was used in place of it (the amount of water was increased), as shown in Table 5 below. 
     Comparative Example 2C 
     A cosmetic composition was produced in the same manner as in Example 1C, except that hydroxyethyl cellulose (by Tokyo Chemical Industry) was used in place of the cellulose fibers T1 in Example 1C, as shown in Table 5 below. 
     Comparative Examples 3C to 5C 
     Cosmetic compositions were produced in the same manner as in Example 1C, except that the cellulose fibers H1 to H3, respectively, were used in place of the cellulose fibers T1 in Example 1C, as shown in Table 5 below.

     Thus obtained, the cosmetic compositions of Examples 1C to 3C and Comparative Examples 1C to 5C were evaluated for the properties thereof according to the same criteria as above. The results are shown in the above Table 4 and Table 5. 
     From the results in the above Table 4, it is known that the compositions of Examples had a high viscosity and were excellent in dispersion stability, and had good results in evaluation of sticky feeling and rough feeling. In addition, it is confirmed that the compositions of Examples were good in evaluation of dispersion stability, as kept almost stable for 2 months or more. In particular, the compositions of Examples 1C to 3C using the cellulose fibers T1 to T3 each having a high carboxyl group content had better results in every evaluation. 
     As opposed to these, the composition of Comparative Example 1C not containing the cellulose fibers T1 had a low viscosity, had a sticky feeling and was poor in evaluation of dispersion stability. The composition of Comparative Example 2C using hydroxyethyl cellulose in place of the cellulose fibers T1 had a low viscosity, had a sticky feeling and was poor in evaluation of dispersion stability. The composition of Comparative Example 3C using the cellulose fibers H1 had a lower viscosity than that of the compositions of Examples, had a sticky feeling and a rough feeling and was poor in evaluation of dispersion stability. The composition of Comparative Example 4C using the cellulose fibers H2 also had a lower viscosity than that of the compositions of Examples, and had a sticky feeling. The composition of Comparative Example 5C using the cellulose fibers H3 had a low viscosity, and had a sticky feeling. 
     [Examples of Gel-Type Composition] 
     Examples of the gel-type composition along with Comparative Examples are described next. However, the present invention (gel-type composition) should not be limited to these Examples. 
     Prior to Examples and Comparative Examples, cellulose fibers S1′ to S3′ for Examples and cellulose fibers H1′ and H2′ for Comparative Examples were prepared as follows. 
     [Production of Cellulose Fibers S1′ (for Examples)] 
     (1) Oxidation Step 
     Undried sulfite-bleached soft wood pulp (mainly including fibers having a fiber size of more than 1000 nm) in an amount corresponding to 200 g of the dry weight thereof, and 2.5 g of TEMPO and 25 g of sodium bromide were dispersed in 1500 ml of water, and an aqueous 13 wt. % sodium hypochlorite solution was added thereto so that the amount of sodium hypochlorite could be 5.4 mmol relative to 1.0 g of the pulp, and the reaction was started. During the reaction, an aqueous 0.5 M sodium hydroxide solution was kept dropwise added thereto to keep the pH at from 10 to 11, and at the time when no pH change could be seen, the reaction was considered to have ended (reaction time, 120 minutes). 
     (2) Purification Step 
     The reaction product was filtered through a glass filter; washed with a sufficient amount of ion-exchanged water; and filtered, and the electric conductivity of the resulting filtrate was measured. At the time when there could be seen no electric conductivity change of the filtrate after repeated washing with water, the purification step was finished. In that manner, water-containing cellulose fibers S1′ having a solid content of 15% by weight were produced. 
     [Production of Cellulose Fibers S2′ and S3′ (for Examples), and Cellulose Fibers H1′ and H2′ (for Comparative Examples)] 
     Cellulose fibers S2′, S3′, H1′ and H2′ were produced in the same manner as that for the production of the cellulose fibers S1′ except that the amount of sodium hypochlorite to be added and the reaction time were changed as in the following Table 6.

     Thus obtained, the cellulose fibers S1′ to S3′ and H1′ and H2′ were analyzed for the following items, according to the criteria mentioned below. The results are shown in the above Table 6. 
     [Maximum Fiber Diameter, Number-Average Fiber Diameter] 
     Water was added to each of the above-mentioned cellulose fibers S1′ to S3′ and H1′ and H2′ to give a 2 wt. % slurry, and using a disperser-type mixer, followed by fibrillating at a number of revolutions of 8,000 rpm for 10 minutes to observation with a transmission electronic microscope (TEM) (JEOL&#39;s JEM-1400) to determine the maximum fiber diameter and the number-average fiber diameter of the cellulose fibers. Specifically, the cellulose fibers were cast onto a hydrophilicated carbon film-coated grid, and stained with 2% uranyl acetate. On the stained negative TEM image (10000-power magnifications) of the sample, the maximum fiber diameter and the number-average fiber diameter of the cellulose fibers were calculated according to the method mentioned above. 
     [Determination of Amount of Carboxyl Group] 
     By processing with the above-mentioned disperser-type mixer for about 10 minutes, 60 ml of a slurry was prepared, and its pH was controlled to be about 2.5 with an aqueous 0.1 M hydrochloric acid solution added thereto. An aqueous 0.05 M sodium hydroxide solution was dropwise added thereto, and its electric conductivity was measured. The measurement was continued until the pH could reach about 11. From the amount of sodium hydroxide (V) consumed in the neutralization stage of the weak acid having a gentle change of electric conductivity, the amount 1 of the functional group (the amount of the carboxyl group) was calculated according to the following formula (1).
 
[Numerical Formula]
 
Amount of Functional Group 1 (mmol/g)= V  (ml)×0.05/(mass of cellulose, g)  (1)
 
[Measurement of Amount of Aldehyde Group]
 
     The cellulose fibers were further oxidized in an aqueous 2% sodium hypochlorite solution, which had been controlled to have a pH of from 4 to 5 with acetic acid, for 48 hours at room temperature (25° C.), and the amount 2 of the functional group was determined according to the above formula (1). With that, the amount of the functional group added by this oxidation (amount of functional group 2−amount of functional group 1) was calculated, and this is the amount of the aldehyde group. 
     [Confirmation of Cellulose I-Type Crystal Structure, Carboxyl Group and Aldehyde Group] 
     A part of the slurry was dried to give a transparent cellulose film, and the wide-angle X-ray diffraction image of the film confirmed the presence of the cellulose I-type crystal structure in the fibers. In addition, in the attenuated total IR reflectiometry (ATR) of the sample, the presence of carbonyl group-caused absorption (at around 1608 cm −1 ) and acid-type carboxyl group (COOH)-caused absorption (at around 1730 cm −1 ) was confirmed. 
     Examples 1D to 9D, Comparative Examples 1D to 8D 
     Water was added to each of the cellulose fibers S1′ to S3′ and H1′ and H2′ to obtain a slurry having the concentration shown in the following Table 7. Using a disperser-type mixer, the slurry was fibrillated at a number of revolutions of 8,000 rpm for 10 minutes to prepare a sample. In Table 7, the amount of water added (the same shall apply hereinunder) was calculated by subtracting the amount of the cellulose fibers added.

     Thus obtained, the samples were evaluated for the properties thereof according to the criteria mentioned below. The results are shown in the above Table 7. 
     [Measurement of Viscosity] 
     The obtained sample (composition) was left at 25° C. for 24 hours, and then its viscosity was measured with a BH-type viscometer (Rotor No. 4) (Toki Sangyo&#39;s BH-type viscometer) at a number of revolutions of 2.5 rpm (3 minutes). 
     [State of Gel] 
     Each sample was visually checked for the gel-like state thereof after 1 day, after 1 week and after 2 weeks. Gel-like samples were evaluated as “◯”; liquid (flowable) samples were as “x”; and samples separated into gel and water were as “separated”. 
     From the results in the above Table 7, it is known that the compositions of Examples 1D to 9D, in which any of the cellulose fibers S1′ to S3′ having an aldehyde group content of from 0.08 to 0.3 mmol/g and a carboxyl group content of from 0.6 to 2.0 mmol/g were used and in which the content of the cellulose fibers was from 0.3 to 5.0% by weight, kept gel after stored for 2 weeks. 
     As opposed to these, the compositions of Comparative Examples 1D, 3D and 5D, in which any of the cellulose fibers S1′ to S3′ having an aldehyde group content of from 0.08 to 0.3 mmol/g and a carboxyl group content of from 0.6 to 2.0 mmol/g were used and in which the content of the cellulose fibers was lower than the lower limit (0.3% by weight), could not be gel. The compositions of Comparative Examples 2D, 4D and 6D, in which any of the cellulose fibers S1′ to S3′ having an aldehyde group content of from 0.08 to 0.3 mmol/g and a carboxyl group content of from 0.6 to 2.0 mmol/g were used and in which the content of the cellulose fibers was more than the upper limit (5.0% by weight), could not disperse uniformly since their viscosity was high, and could not also be gel. 
     In the composition of Comparative Example 7D, in which the cellulose fibers H1′ having a carboxyl group content of less than 0.6 mmol/g were used, the cellulose fibers partly settled out and separated after 1 day. The composition of Comparative Example 8D, in which the cellulose fibers H2′ having a carboxyl group content of more than 2.0 mmol/g were used, failed to be gel with time and expressed flowability. 
     Next, using the above-mentioned cellulose fibers, water (liquid dispersion medium) and functional additives (inorganic salts, etc.), gel-type compositions were produced. 
     Examples 10D to 222D, Comparative Examples 9D to 148D 
     Water and functional additives (inorganic salts, surfactants, oils, moisturizers, antiseptics, inorganic fine particles, organic fine particles, organic solvents, fragrances, deodorants) shown in the following Table 8 to Table 38 were added to the cellulose fibers S1′ to S3′ and H1′ and H2′ in such a manner that the concentration of the cellulose fibers in the resulting slurry could be as in those Table 8 to Table 38, and, using a disperser-type mixer, the slurry was fibrillated at a number of revolutions of 8,000 rpm for 10 minutes, thereby preparing samples. In Table 8 to Table 38, the amount of water added (the same shall apply hereinunder) is calculated by subtracting the amount of the cellulose fibers and that of the functional additives. 
     Conventional Examples 1D to 27D 
     The cellulose fibers obtained according to the method described in WO99/28350 were used here. Specifically, a pulp sheet was cut into chips of 5 mm×5 mm to prepare a wood pulp having a degree of polymerization of 760, followed by dissolving in an aqueous 65% sulfuric acid solution at −5° C. in such a manner that the cellulose concentration in the resulting dope could be 5%, with stirring at 150 rpm for 10 minutes to give a transparent uniform cellulose dope. With stirring, the cellulose dope was poured into water (5° C.) in an amount of 2.5 times by weight the dope, to prepare a suspension of cellulose flocs. The suspension was hydrolyzed at 85° C. for 20 minutes, and then fully washed with water and filtered repeatedly many times until the pH of the wash waste could reach 4 or more to prepare white and transparent gel-like cellulose fibers having a cellulose concentration of 15%. The gel product was stirred and homogenized with a household-use food processor (knife cutter) for 3 minutes, and water and functional additives shown in the following Table 39 and Table 40 ([inorganic salts] NaCl, KCl, CaCl 2 , MgCl 2 , (NH 4 ) 2 SO 4 , Na 2 CO 3 , [surfactants] surfactants 1 to 3, [oils] oil 1 to 3, [organic solvents] organic solvent 1, 2) were added thereto to be in the predetermined concentration shown in the Tables, by which the sample was diluted to have a cellulose concentration of 1.5%, followed by further stirring with a blender at a number of revolutions of 15,000 rpm for 5 minutes. Next, the thus-diluted sample was homogenized four times with an ultrahigh-pressure homogenizer (Mizuho Industry&#39;s Microfluidizer M-110EH Model, operation pressure 1,750 kg/cm 2 ). The fibrillated cellulose fibers (A1′) with water alone added thereto (blank) and processed four times had a mean particle size of 0.18 μm, and the transmittance of the dispersion was 95%. 
     Conventional Examples 28D to 51D 
     Using a disperser-type mixer, water and functional additives shown in the following Table 41 ([inorganic salts] NaCl, KCl, CaCl 2 , MgCl 2 , (NH 4 ) 2 SO 4 , Na 2 CO 3 , [surfactants] surfactant 3, [oils] oil 1 to 3, [inorganic fine particles] inorganic fine particles 1, 2) were mixed to prepare an aqueous solution or an aqueous dispersion so as to finally have the predetermined concentration as in the Table. Using a disperser-type stirrer, 0.50 g of carboxyvinyl polymer A2′ (BF Goodrich&#39;s Carbopol 980 was gradually added to and dispersed in 97.5 g of the above aqueous solution or dispersion, with stirring at a number of revolutions of 8,000 rpm. For neutralization and thickening, 2.0 g of an aqueous 10% sodium hydroxide solution was dropwise added thereto. For fully homogenizing it, the sample was stirred for 10 minutes. The viscosity of the sample formed of water and carboxyvinyl polymer A2′ alone (blank) was 61.0 Pa·s. 
     The functional additives shown in the following Table 8 to Table 41 are as follows.

     Thus obtained, the samples (compositions) were evaluated for the properties thereof according to the same criteria as mentioned above. The results are shown in the above Table 8 to Table 41. 
     From the results in the above Table 8 to Table 41, it is known that the compositions of Examples, in which any of the cellulose fibers S1′ to S3′ having an aldehyde group content of from 0.08 to 0.3 mmol/g and a carboxyl group content of from 0.6 to 2.0 mmol/g were used and in which the content of the cellulose fibers was from 0.3 to 5.0% by weight, kept gel and their viscosity reduction was small even when various functional additives (inorganic salts, etc.) were added thereto. However, the conventional compositions separated or could not keep gel as their viscosity reduction was great when various functional additives were added thereto. 
     As opposed to these, the compositions of Comparative Examples, in which any of the cellulose fibers S1′ to S3′ having an aldehyde group content of from 0.08 to 0.3 mmol/g and a carboxyl group content of from 0.6 to 2.0 mmol/g were used but in which the content of the cellulose fibers was lower than the lower limit (0.3% by weight), could not keep gel after one day. The compositions of Comparative Examples, in which any of the cellulose fibers S1′ to S3′ having an aldehyde group content of from 0.08 to 0.3 mmol/g and a carboxyl group content of from 0.6 to 2.0 mmol/g were used but in which the content of the cellulose fibers was more than the upper limit (5.0% by weight), could not be macroscopically homogeneous gel-type compositions. 
     In the compositions of Comparative Examples using the cellulose fibers H1′ having a carboxyl group content of less than 0.6 mmol/g, the cellulose fibers partly separated and settled out to form macroscopically nonhomogeneous gel. The compositions of Comparative Examples using the cellulose fibers H2′ having a carboxyl group content of more than 2.0 mmol/g became flowable with time, and after 2 days, the composition could not keep gel. 
     Examples of Spray Composition 
     Next described are Examples of the spray composition along with Comparative Examples. However, the present invention (spray composition) should not be limited to these Examples. 
     Prior to Examples and Comparative Examples, cellulose fibers S1″ to S3″ for Examples and cellulose fibers H1″ and H2″ for Comparative Examples were prepared as follows. 
     [Production of Cellulose Fibers S1″ (for Examples)] 
     (1) Oxidation Step 
     Undried sulfite-bleached soft wood pulp (mainly including fibers having a fiber size of more than 1000 nm) in an amount corresponding to 200 g of the dry weight thereof, and 2.5 g of TEMPO and 25 g of sodium bromide were dispersed in 1000 ml of water, and an aqueous 13 wt. % sodium hypochlorite solution was added thereto so that the amount of sodium hypochlorite could be 5.4 mmol relative to 100 g of the pulp, and the reaction was started. During the reaction, an aqueous 0.5 M sodium hydroxide solution was kept dropwise added thereto to keep the pH at from 10 to 11, and at the time when no pH change could be seen, the reaction was considered to have ended (reaction time, 120 minutes). 
     (2) Purification Step 
     The reaction product was filtered through a glass filter, washed with a sufficient amount of ion-exchanged water and filtered, and the electric conductivity of the resulting filtrate was measured. At the time when there could be seen no electric conductivity change of the filtrate after repeated washing with water, the purification step was finished. In that manner, water-infiltrated reaction product fibers having a solid content of 20% by weight were produced. 
     (3) Dispersion Step (Fibrillation Step) 
     Water was added to the reaction product fibers to prepare a 2.0 wt. % slurry, and using an ultrahigh-pressure homogenizer (Microfluidizer, Model M-110-E/H, by Mizuho Industry), followed by processing twice under an operation pressure of 1.72×10 8  Pa, thereby giving fibrillated cellulose fibers S1″. 
     [Production of Cellulose Fibers S2″ and S3″ (for Examples), and Cellulose Fibers H1″ and H2″ (for Comparative Examples)] 
     Cellulose fibers S2″ and S3″(for Examples) and H1″ and H2″ (for Comparative Examples) were produced in the same manner as that for the production of the cellulose fibers S1″ except that the amount of sodium hypochlorite to be added and the reaction time were changed as in the following Table 42.

     Thus obtained the cellulose fibers S1″ to S3″ and H1″ and H2″ were analyzed for the following items, according to the criteria mentioned below. The results are shown in the above Table 42. 
     [Maximum Fiber Diameter, Number-Average Fiber Diameter] 
     Through TEM observation, the maximum fiber diameter and the number-average fiber diameter of the cellulose fibers were determined. Briefly, the cellulose fibers were cast onto a hydrophilicated carbon film-coated grid, and stained with 2% uranyl acetate. On the stained negative TEM image of the sample, the fibers were analyzed. 
     [Determination of Amount of Carboxyl Group] 
     After preparing 60 ml of a 2.0 wt. % slurry of the cellulose fibers, its pH was made about 2.5 with an aqueous 0.1 M hydrochloric acid solution added thereto. Subsequently, an aqueous 0.05 M sodium hydroxide solution was dropwise added thereto, and its electric conductivity was measured. The measurement was continued until the pH could reach about 11. From the amount of sodium hydroxide (V) consumed in the neutralization stage of the weak acid having a gentle change of electric conductivity, the amount (a) of the functional group (the amount of the carboxyl group) was calculated according to the following formula (2).
 
[Numerical Formula 4]
 
Amount of Functional Group (mmol/g)= V  (ml)×0.05/(mass of cellulose, g)  (2)
 
[Measurement of Amount of Aldehyde Group]
 
     The cellulose fibers were further oxidized in an aqueous 2 wt. % sodium hypochlorite solution, which had been controlled to have a pH of from 4 to 5 with acetic acid, for 48 hours at room temperature (25° C.). It was again neutralized, and from the amount (V) of sodium hydroxide consumed in the neutralization, the amount (b) of the functional group was determined according to the above formula (2). With that, the amount of the functional group added by this oxidation [(b)-(a)] was calculated, and this is the amount of the aldehyde group. 
     [Confirmation of Crystal Structure, Carboxyl Group and Aldehyde Group] 
     A part of the slurry was dried to give a transparent cellulose film, and the wide-angle X-ray diffraction image of the film confirmed the presence of the cellulose I-type crystal structure in all the cellulose fibers S1″ to S3″ and H1″ and H2″. In addition, in the attenuated total IR reflectiometry (ATR) of the sample, the presence of carbonyl group-caused absorption (at around 1608 cm −1 ) and acid-type carboxyl group (COOH)-caused absorption (at around 1730 cm −1 ) in all these cellulose fibers was confirmed. 
     [Confirmation on  13 C-NMR Chart] 
     As to whether or not the hydroxyl group alone at the C6-position in the glucose unit in the surface of the cellulose fibers was selectively oxidized into a carboxyl group, the sample was confirmed on the  13 C-NMR chart thereof. Specifically, the peak at 62 ppm corresponding to the C6-position of the primary hydroxyl group of the glucose unit, as confirmed on the  13 C-NMR chart of the cellulose before oxidation, disappeared after the oxidation, and in place of it, a peak derived from the carboxyl group appeared at 178 ppm. From this, it was confirmed that, in the cellulose fibers S1″ to S3″, the C6-position hydroxyl group alone of the glucose unit was oxidized into an aldehyde group and a carboxyl group. 
     [Production of Cellulose Fine Particles (for Comparative Examples)] 
     According to Example 1 described in JP-A 2003-73229, cellulose fine particles were produced. Specifically, a starting pulp having a mean degree of polymerization (DP) of 760, as prepared by cutting a pure pulp sheet into chips of 5 mm×5 mm, was dissolved in an aqueous 65 wt. % sulfuric acid solution at −5° C. in such a manner that the cellulose concentration could be 5% by weight to prepare a transparent and viscous cellulose dope. The cellulose dope was poured into water (5° C.) in an amount of 2.5 times by weight of the dope with stirring to prepare a suspension of solid cellulose flocs. The suspension was hydrolyzed at 85° C. for 20 minutes, then the dispersion medium of the aqueous sulfuric acid solution was removed by filtration under reduced pressure through a glass filter. This was fully washed with water repeatedly many times until the pH of the wash waste could reach about 3, then washed (neutralized) with an aqueous dilute ammonia solution at a pH of about 11, and further washed with ion-exchanged water to prepare a semitransparent white gel having a cellulose concentration of 6.0% by weight. Thus obtained, the gel was diluted with water to have a cellulose concentration of 4.0% by weight, and dispersed with a homomixer (T.K. Robomix by Primix) at a number of revolutions of 15000 rpm for 10 minutes, and then processed five times with an ultrahigh-pressure homogenizer (Microfluidizer Model M-110-E/H, by Mizuho Industry) under an operation pressure of 1.72×10 8  Pa to prepare a highly-transparent cellulose (aqueous dispersion of cellulose fine particles) (pH=6.7). 
     Examples 1E to 9E, Comparative Examples 1E to 11E 
     First, the cellulose fibers S1″ to S3″ and H1″ and H2″ (cellulose fibers for Examples and Comparative Examples) produced in the above were prepared as a thickener. In addition, the cellulose fine particles produced in the above, as well as a carboxyvinyl polymer (Carbopol 980, sold by Chugai Trade), a polyacrylamide (having a mean molecular weight of from 9,000,000 to 10,000,000, by Kishida Chemical), and synthetic smectite fine particles (Smecton SA, by Kunimine Industry) were also prepared. Ion-exchanged water alone was added to the thickener to prepare samples having a concentration of 0.5% by weight, 1.0% by weight or 1.5% by weight (see Table 43). The carboxyvinyl polymer solution (Comparative Examples 6E, 7E) was, after the carboxyvinyl polymer had been dissolved therein, neutralized with dilute ammonia water. Each sample prepared as above was dispersed with a homomixer (T.K. Robomix, by Primix) at a number of revolutions of 15000 rpm for 10 minutes to prepare a spray composition. 
     By using a cone-plate type rotatory viscometer (Rheosol-G2000, by UBM), the spray composition thus produced as above was analyzed at 20° C. in a shear rate region including from 1×10 −3  S −1  to 1×10 3  S −1 , and the maximum value (η max ) and the minimum value (η min ) of the viscosity thereof are shown in the following Table 43. 
     Each spray composition was charged in a commercially-available dispenser-type spray atomizer having a capacity of 50 ml (by SANPLATEC), and tested for the spraying characteristics (atomizability) thereof according to the following test method and criteria. The results are shown in the following Table 43. 
     &lt;Test Method and Criteria&gt; 
     [Gel State] 
     The spray atomizer filled with the composition was turned upside down, and the movement of the liquid surface was checked visually. The composition in which a part of the cellulose fibers or the functional additive had separated was expressed as “separated” in the Table. 
     x: When turned upside down, the liquid surface immediately moved greatly. 
     Δ: When turned upside down, the liquid surface moved slowly. 
     ◯: When turned upside down, the liquid surface did not move. 
     [Spray Condition] 
     Actually sprayed, the composition was checked for the spraying condition thereof. 
     x: The composition was not jetted out through the nozzle and spraying was impossible; or the composition could be jetted out through the nozzle but could not be misty. 
     ◯: The composition was jetted out through the nozzle as a good mist. 
     [Spraying Unevenness] 
     A frosted glass plate of 18 cm×18 cm was stood vertically, and at a position spaced by 20 cm as the vertical distance therebetween, the spray atomizer was pushed once toward the glass plate, and immediately, the dispersion condition of the liquid droplets having adhered to the glass surface was observed. This was compared with a control case where ion-exchanged water alone was used as the mother liquid of spray. 
     x: Large droplets scattered, and obvious spraying unevenness was confirmed. 
     Δ: Large droplets were not seen, but as compared with the case of ion-exchanged water alone, the distribution of the droplets was rough. 
     ◯: Liquid droplets distributed densely on the same level as or on a higher level than that of the case of ion-exchanged water alone 
     [Dripping] 
     Under the same condition as that in evaluation of spraying unevenness, the spraying was repeated a few times and continued until liquid droplets could be sprayed on the vertical glass face densely with no space therebetween, and while the glass place was kept stood vertically, the sprayed surface was checked at every spraying for the presence or absence of dripping thereon. 
     x: In one spraying, dripping occurred. 
     Δ: In one spraying, dripping did not occur, but with the increase in the thickness of the sprayed liquid on the glass surface, dripping occurred. 
     ◯: In spraying multiple times, no dripping occurred.

     As obvious from the results in the above Table, it is known that the spray compositions of Examples 1E to 9E showed a good gel state and good spray characteristics. As opposed to these, in the spray compositions of Comparative Examples 1E to 2E, a part of cellulose settled out. Therefore, during spraying, the nozzle clogged and spraying became impossible. The spray compositions of Comparative Examples 3E to 5E were disadvantageous in that the gel state thereof was poor and the sprayed composition could not form a mist. Of the compositions of Comparative Examples 6E to 9E in which carboxyvinyl polymer or polyacrylamide was used as a thickener, the spray characteristics were bad, and it is known that the viscous liquid of those Comparative Examples is unsuitable as a spray composition. Although the compositions of Comparative Examples 10E to 11E in which synthetic smectite fine particles were used as the thickener had good gel characteristics and spray characteristics, they were problematic in that they drip when their concentration is low as in these cases and there was the problem of the compositions of the type is that their concentration must be high. 
     Examples 10E to 27E, Comparative Examples 12E to 29E 
     First, the thickeners (cellulose fibers S1″ to S3″ and H1″ and H2″, and cellulose fine particles) used in the above-mentioned Examples and Comparative Examples were prepared. Ion-exchanged water, and inorganic salt/electrolyte (any of sodium chloride, sodium edetate, sodium ascorbate) as in the combination shown in the following Table 44 to Table 46 were added to each thickener to prepare a sample having a thickener concentration of 0.5% by weight, 1.0% by weight or 1.5% by weight (see Table 44 to Table 46), and an inorganic salt/electrolyte concentration of 0.1% by weight. Thus prepared, the sample was dispersed with a homomixer (T.K. Robomix, by Primix) at a number of revolutions of 15000 rpm for 10 minutes, thereby preparing a spray composition. 
     By using a cone-plate type rotatory viscometer (Rheosol-G2000, by UBM), the spray composition thus produced as above was analyzed at 20° C. in a shear rate region including from 1×10 −3  S −1  to 1×10 3  S −1 , and the maximum value (η max ) and the minimum value (η min ) of the viscosity thereof are shown in the following Table 44 to Table 46. 
     Each spray composition was charged in a commercially-available dispenser-type spray atomizer having a capacity of 50 ml (by SANPLATEC), and tested for the spraying characteristics (atomizability) thereof according to the test method and criteria indicated in the above-mentioned Examples 1E to 9E and Comparative Examples 1E to 11E. The results are shown in the following Table 44 to Table 46.

     As obvious from the results in the above Tables, it is known that the spray compositions of Examples using any of the cellulose fibers S1″ to S3″ all showed a good gel state and good spray characteristics even though an inorganic salt or an electrolyte was added thereto. As opposed to these, of the spray compositions of Comparative Examples using the cellulose fibers H1″ or H2″ or the cellulose fine particles as the thickener, the viscosity greatly lowered owing to addition of the inorganic salt or the electrolyte thereto, and as a result, the compositions could hardly keep the gel state thereof (some separated). Though they could be sprayed, there occurred spraying unevenness or dripping. Some of them failed to be sprayed on the way as the flocs formed therein clogged the nozzle. 
     Examples 28E to 45E, Comparative Examples 30E to 46E 
     The thickeners (cellulose fibers S1″ to S3″ and H1″ and H2″, and cellulose fine particles) used in the above-mentioned Examples and Comparative Examples were prepared. Ion-exchanged water, and additive (any of ethanol, dimethylpolysiloxane, glyceryl trioctanoate) as in the combination shown in the following Table 47 to Table 49 were added to each thickener in such a manner that the concentration of the thickener could be as in the following Table 47 to Table 49. The sample thus prepared was dispersed with a homomixer (T.K. Robomix, by Primix) at a number of revolutions of 15000 rpm for 10 minutes, thereby preparing a spray composition. 
     Using a cone-plate type rotatory viscometer (Rheosol-G2000, by UBM), the spray composition thus produced as above was analyzed at 20° C. in a shear rate region including from 1×10 −3  S −1  to 1×10 3  S −1 , and the maximum value (η max ) and the minimum value (η min ) of the viscosity thereof are shown in the following Table 47 to Table 49. 
     Each spray composition was charged in a commercially-available dispenser-type spray atomizer having a capacity of 50 ml (by SANPLATEC), and tested for the spraying characteristics thereof according to the test method and criteria indicated in the above-mentioned Examples 1E to 9E and Comparative Examples 1E to 11E. The results are shown in the following Table 47 to Table 49.

     As obvious from the results in the above Tables, it is known that, though their viscosity somewhat lowered owing to addition of the oil or the alcohol thereto, the spray compositions of Examples using any of the cellulose fibers S1″ to S3″ all showed a good gel state and good spray characteristics by somewhat increasing the amount of the cellulose fibers therein. As opposed to these, of the spray compositions of Comparative Examples using the cellulose fibers H1″ or H2″ or the cellulose fine particles as the thickener, the viscosity greatly lowered owing to addition of the oil or the alcohol, and as a result, the compositions could hardly keep the gel state thereof (some separated). Regarding the spray characteristics of the compositions, there occurred remarkable spraying unevenness or dripping. Some of them failed to be sprayed on the way as the flocs formed therein clogged the nozzle. 
     Examples 46E to 51E, Comparative Examples 47E to 52E 
     The thickeners (cellulose fibers S1″ to S3″ and H1″ and H2″, and cellulose fine particles) used in the above-mentioned Examples and Comparative Examples were prepared. Ion-exchanged water, and as an additive, titanium oxide (TTO-V3, by Ishihara Sangyo) were added to each thickener in such a manner that the concentration of the thickener could be as in the following Table 50, and that the titanium oxide concentration could be 0.1% by weight. The sample thus prepared was dispersed with a homomixer (T.K. Robomix, by Primix) at a number of revolutions of 15000 rpm for 10 minutes, thereby preparing a spray composition. 
     Using a cone-plate type rotatory viscometer (Rheosol-G2000, by UBM), the spray composition thus produced as above was analyzed at 20° C. in a shear rate region including from 1×10 −3  S −1  to 1×10 3  S −1 , and the maximum value (η max ) and the minimum value (η min ) of the viscosity thereof are shown in the following Table 50. 
     Each spray composition was charged in a commercially-available dispenser-type spray atomizer having a capacity of 50 ml (by SANPLATEC), and tested for the spraying characteristics thereof according to the test method and criteria indicated in the above-mentioned Examples 1E to 9E and Comparative Examples 1E to 11E. The results are shown in the following Table 50.

     As obvious from the results in the above Table, it is known that, though their viscosity somewhat lowered owing to addition of titanium oxide thereto, the spray compositions of Examples using any of the cellulose fibers S1″ to S3″ all showed a good gel state and good spray characteristics by somewhat increasing the amount of the cellulose fibers therein. As opposed to these, the spray compositions of Comparative Examples using the cellulose fibers H1″ or H2″ or the cellulose fine particles as the thickener separated while releasing water in the upper part thereof, though they kept gel. In addition, regarding the spray characteristics of the compositions, spraying unevenness that would be caused by separation was remarkably observed. 
     INDUSTRIAL APPLICABILITY 
     The viscous composition of the present invention is usable as a cosmetic composition, a gel-type composition, a spray composition, etc. The cosmetic composition can be used in various applications of, for example, skincare cosmetics such as face lotion, emulsion, cold cream, vanishing cream, massage cream, emollient cream, cleansing cream, beauty essence, pack, foundation, sunscreen cosmetic, sun-tanning cosmetic, moisture cream, hand cream, skin-whitening emulsion, various lotions, etc.; hair-care cosmetics such as shampoo, rinse, hair conditioner, rinse-in shampoo, hair-styling agent (hair foam, gel-type hair dressing, etc.), hair treatment agent (hair cream, treatment lotion, etc.), hair dye, lotion-type hair-growing agent, hair tonic, etc.; cleaning agents such as hand cleaner, etc.; as well as pre-shaving lotion, after-shaving lotion, air freshener, dentifrice, ointment, adhesive patch, etc. 
     The gel-type composition uses cellulose fibers of a natural material and is rich in compatibility with various functional additives. Therefore, it is favorably and widely used for cosmetic bases and bases of toiletries such as air refreshers, etc.
