Description:
This application claims benefit of U.S. Provisional Application No. 60/736,301, filed Nov. 15, 2005, the contents of which are incorporated herein by reference. This application also claims benefit of priority under 35 U.S.C. §119 to French Patent Application No. FR 05 53285, filed Oct. 28, 2005, the contents of which are also incorporated herein by reference. 
    
    
     The present disclosure relates to a cosmetic composition, for example a hair conditioner, comprising at least one cationic surfactant, at least one oxyethylenated sorbitan ester and at least one non-silicone solid fatty substance in a particular ratio, and to a cosmetic process for treating keratin materials, such as the hair. 
     It is well known that hair that has been sensitized (i.e., damaged and/or embrittled) to varying degrees under the action of atmospheric agents or under the action of mechanical or chemical treatments, such as dyeing, bleaching and/or permanent-waving, is often difficult to disentangle and to style, and may lack softness. 
     Cosmetic compositions comprising cationic surfactants have already been proposed for treating keratin materials, such as the hair. 
     However, such compositions may have drawbacks such as rinseability problems, stability problems, difficulties in distributing them over the keratin materials and/or also insufficient cosmetic properties. 
     It has also been recommended to use cationic polymers, cationic silicones or cationic surfactants in compositions for washing or caring for keratin materials such as the hair, to facilitate the disentangling of the hair and/or to give it softness and suppleness. The use of cationic polymers or cations for this purpose, however, may have various drawbacks. On account of their high affinity for the hair, some of these polymers may become deposited in a substantial amount during repeated use, and may lead to undesirable effects such as an unpleasant, laden feel, stiffening of the hair, and/or adhesion between the fibers that affects styling. 
     Furthermore, the care used for very sensitized hair may still be insufficient to treat the ends, which are usually very damaged. 
     In summary, it is found that the current conditioning cosmetic compositions are not always entirely satisfactory. Thus, it is sought to obtain cosmetic compositions that have very good cosmetic properties, for instance on very sensitized hair, and which furthermore have good skin tolerance; for example, the hair conditioning compositions of the prior art may cause discomfort reactions on the scalp and it would be desirable to avoid this. 
     International Patent Application WO 2004/093835 describes compositions containing cationic surfactants, fatty substances and oxyethylenated sorbitan esters. However, the concentrations of sorbitan esters used and the ester/fatty substance ratios are very low. 
     The present inventors have now discovered that the combination of a cationic surfactant, at least one oxyethylenated sorbitan ester and at least one non-silicone solid fatty substance in a particular ratio allows one or more of these drawbacks to be overcome. 
     Hair treated with the composition disclosed herein, such as sensitized hair, may be smooth, may disentangle easily, may be shiny, supple and individualized, and/or may have a soft feel with no feeling of residues. The treated hair may have a natural, unladen appearance. The smoothness may be uniform from the roots to the ends. The ends may show less splitting. These effects are remanent over time. 
     The present inventors have discovered that the addition of a particular weakly oxyethylenated sorbitan ester makes it possible, surprisingly, to reduce the discomfort reactions (itching, redness, etc.), for example on the scalp, of compositions containing surfactants liable to cause reactions of this type when they are used alone. 
     Thus, according to the present disclosure, novel cosmetic compositions are now proposed, comprising, in a cosmetically acceptable aqueous medium, at least one cationic surfactant, at least one ester of sorbitan and of a saturated or unsaturated, linear or branched C 8 -C 30  fatty acid with a number of moles of ethylene oxide of less than or equal to 20, and at least one non-silicone solid fatty substance, wherein the at least one oxyethylenated sorbitan ester and the at least one non-silicone solid fatty substance are present in a weight ratio ranging from 0.2 to 50. 
     Another aspect of the present disclosure is a cosmetic process for treating keratin materials, such as the hair, using the above-mentioned composition. 
     Another aspect of the present disclosure is the use of the composition as a hair conditioner. 
     Other subjects, characteristics, aspects and advantages of the present disclosure will emerge even more clearly on reading the description and the various examples that follow. 
     According to the present disclosure, the term “sensitized hair” is generally understood to mean hair that has undergone external physical attack (by light, heat, waves, etc.), mechanical attack (by repeated blow-drying, combing or brushing, etc.) and/or chemical attack (by oxidation dyeing, bleaching, permanent-waving, relaxing, etc.). For instance, in at least one embodiment, the compositions according to the present disclosure are effective on hair sensitized by chemical attack. 
     As disclosed herein the term “at least one” will be generally understood as meaning “one or more”, i.e. one, two, three or more. 
     The term “cosmetically acceptable medium” means a medium that is compatible with any keratin material, such as the skin, the hair, the nails, the eyelashes, the eyebrows or the lips and any other area of the body and of the face. 
     For purposes of the present disclosure, the term “non-silicone fatty substance” means any oily organic substance not comprising any silicone atoms in its elemental structure, comprising at least one carbon-based chain containing at least 10 carbon atoms, and whose solubility in water at 25° C. (1 atm) is less than 0.1% by weight. 
     For instance, the solid fatty substances may have a melting point of greater than or equal to 35° C. and/or have a viscosity at a temperature of 40° C. and at a shear rate of 1 s −1  of greater than or equal to 1 Pa-s. 
     According to at least one embodiment of the present disclosure, the at least one solid fatty substance is non-polymeric, i.e., it does not comprise any repeated monomer units other than alkylene oxide units. 
     The compositions according to the present disclosure are non-washing (non-detergent) compositions, and, in at least one embodiment, comprise less than 3% by weight, such as less than 1% by weight, of detergent surfactants, such as anionic surfactants, relative to the total weight of the composition. In a further embodiment, the composition does not contain any detergent surfactants. 
     According to at least one embodiment of the present disclosure, the oxyethylenated sorbitan ester/solid fatty substance weight ratio ranges from 0.25 to 10, for example from 0.3 to 5, such as from 0.4 to 2 or from 0.5 to 1.75. 
     The fatty acids of the sorbitan esters of a C 8 -C 30  fatty acid, with a number of moles of ethylene oxide of less than or equal to 20, may, in at least one embodiment, comprise from 8 to 24 carbon atoms and further, for example, from 8 to 18 carbon atoms. In at least one embodiment, the fatty acids may be chosen from lauric acid, palmitic acid, oleic acid and stearic acid, for instance from lauric acid and stearic acid. In a further embodiment, the fatty acid is lauric acid. 
     Monoesters of a C 8 -C 24  fatty acid and of oxyethylenated sorbitan may be used in at least one embodiment. For instance, the number of moles of ethylene oxide may be less than 10, such as from 3 to 8, mol of ethylene oxide, and in a further embodiment may be equal to 4 mol. 
     As disclosed herein, sorbitan esters may include but are not limited to sorbitan monolaurate oxyethylenated with 4 mol of ethylene oxide (4 EO) or polysorbate 21, sorbitan monostearate oxyethylenated with 4 mol of ethylene oxide (4 EO) or polysorbate 61, and sorbitan monooleate oxyethylenated with 5 mol of ethylene oxide (5 EO) or polysorbate 81.

     According to the present disclosure, the oxyethylenated sorbitan ester may be present in the cosmetic composition in an amount ranging from 0.4% to 10%, for example ranging from 0.4% to 8% by weight relative to the total weight of the composition. 
     According to at least one embodiment, when the compositions are used in a process without final rinsing, the oxyethylenated sorbitan ester may be present in the cosmetic composition in an amount ranging from 0.4% to 5%, for instance from 2% to 6% by weight relative to the total weight of the composition. 
     According to another embodiment, when the compositions are used in a process with final rinsing, the oxyethylenated sorbitan ester may be present in the cosmetic composition in an amount ranging from 0.4% to 8%, for instance from 0.4% to 2% by weight relative to the total weight of the composition. 
     The composition according to the present disclosure comprises at least one cationic surfactant that is well known per se, such as optionally polyoxyalkylenated primary, secondary or tertiary fatty amine salts and quaternary ammonium salts, and mixtures thereof. 
     According to the present disclosure, the cationic surfactants are non-polymeric, i.e., they do not comprise any repeating monomer units. In at least one embodiment, the cationic surfactants according to the present disclosure may contain one or two functions capable of forming cationic charges. 
     Fatty amines that may be mentioned include but are not limited to alkylamidoamines, for instance (C 8 -C 30 )alkylamidodi(C 1 -C 6 )alkylamines, such as stearamidopropyldimethylamine (MACKINE 301 sold by MacIntyre).

     These products are obtained, for example, by direct esterification of optionally oxyalkylenated triethanolamine, triisopropanolamine, alkyldiethanolamine or alkyldiisopropanolamine onto fatty acids or onto mixtures of fatty acids of plant or animal origin, or by transesterification of the methyl esters thereof. This esterification is followed by a quaternization using an alkylating agent such as an alkyl halide (such as a methyl or ethyl halide), a dialkyl sulfate (such as dimethyl or diethyl sulfate), methyl methanesulfonate, methyl para-toluenesulfonate, glycol chlorohydrin or glycerol chlorohydrin.

     The solid fatty substances according to the present disclosure may be crystalline, amorphous or pasty. 
     As disclosed herein, the melting point may range from 35 to 250° C., for example from 40 to 150° C. 
     These solid fatty substances have a viscosity, at a temperature of 40° C. and at a shear rate of 0.1 s −1 , ranging from 1 Pa-s to 1,000,000 Pa-s, for example ranging from 10 to 1,000 Pa-s. 
     The viscosity measurements may be taken at a temperature of about 40° C., using a Carri-Med CSL2-500 viscometer. 
     The melting points may be measured by DSC or on a Köfler bench. The melting point may be measured by differential calorimetric analysis (DSC) with a temperature increase rate of 10° C./minute. The melting point is then the temperature corresponding to the top of the endothermic melting peak obtained during the measurement. 
     The non-silicone solid fatty substances with a melting point of greater than or equal to 35° C. may be chosen from oxyethylenated or non-oxyethylenated fatty alcohols, fatty esters, mineral waxes and organic waxes other than fatty esters and fatty alcohols, and mixtures thereof. 
     For instance, the fatty alcohols according to the present disclosure are linear and saturated, and contain from 12 to 40 carbon atoms. 
     According to at least one embodiment of the present disclosure, the fatty alcohols have the structure R—OH, in which R is a C 12 -C 24  alkyl group. R may be substituted with at least one hydroxyl group, but in at least one embodiment, R is unsubstituted. 
     Non-limiting examples that may be mentioned include myristyl alcohol, cetyl alcohol, stearyl alcohol and behenyl alcohol, and mixtures thereof. 
     The fatty alcohol may be present in a mixture of fatty alcohols, which means that, in a commercial product, several fatty alcohol species may co-exist in the form of a mixture. 
     In at least one embodiment, the fatty alcohols of the present disclosure are non-oxyalkylenated and/or non-glycerolated. These fatty alcohols may be constituents of animal or plant waxes, for example. 
     As disclosed herein, the fatty esters include esters containing at least 10 carbon atoms, for example esters of a carboxylic acid containing at least 10 carbon atoms and of a monoalcohol or a polyol. The fatty esters according to the present disclosure may be monoesters, diesters or triesters. 
     For instance the carboxylic acids may contain from 10 to 30 carbon atoms, for example from 12 to 24 carbon atoms. The alcohols may contain from 10 to 30 carbon atoms, for example from 12 to 24 carbon atoms. As disclosed herein, the solid fatty esters according to the present disclosure include esters of a monocarboxylic fatty acid containing at least 10 carbon atoms and of a monoalcohol containing at least 10 carbon atoms. 
     Esters according to the present disclosure that may be mentioned include but are not limited to cetyl myristate, myristyl myristate, palmityl palmitate, stearyl palmitate, palmityl stearate and stearyl stearate, and mixtures thereof. 
     For instance, the fatty esters may be constituents of animal or plant waxes. 
     For the purposes of the present disclosure, a wax is generally understood to mean a lipophilic compound that is solid at room temperature (about 25° C.), with a reversible solid/liquid change of state, having a melting point of greater than about 40° C., which may be up to 200° C., and having an anisotropic crystal organization in the solid state. In general, the size of the wax crystals is such that the crystals diffract and/or scatter light, giving the composition comprising them a more or less opaque hazy appearance. By bringing the wax to its melting point, it is possible to make it miscible with oils and to form a microscopically uniform mixture, but on returning the temperature of the mixture to room temperature, recrystallization of the wax in the oils of the mixture is obtained, which is detectable microscopically and macroscopically (opalescence). 
     As waxes that may be used in the present disclosure, non-limiting mention may be made of waxes of animal origin such as beeswax, spermaceti, lanolin wax and lanolin derivatives; plant waxes such as carnauba wax, candelilla wax, ouricury wax, Japan wax, cocoa butter, cork fiber wax or sugarcane wax; mineral waxes, for example paraffin wax, petroleum jelly wax, lignite wax or microcrystalline waxes, ozokerites, olive wax, rice wax, hydrogenated jojoba wax, the absolute waxes of flowers, such as the essential wax of blackcurrant blossom sold by the company Bertin (France), animal waxes, for instance beeswaxes or modified beeswaxes (cerabellina); other waxes or waxy starting materials that may be used according to the present disclosure include, for example, marine waxes such as the product sold by the company Sophim under the reference M82, and mixtures thereof. Organic waxes that may also be mentioned include but are not limited to waxes comprising amide functions, such as natural or synthetic ceramides. 
     For the definition of waxes, non-limiting mention may be made, for example, of P. D. Dorgan, Drug and Cosmetic Industry, December 1983, pp. 30-33. 
     In at least one embodiment, the wax(es) is (are) chosen from carnauba wax, candelilla wax, esparto grass wax, paraffin wax, ozokerite, plant waxes, for instance olive wax, rice wax, hydrogenated jojoba wax or the absolute waxes of flowers, such as the essential wax of blackcurrant blossom sold by the company Berlin (France), animal waxes, for instance beeswaxes or modified beeswaxes (cerabellina); other waxes or waxy starting materials that may be used according to the present disclosure include marine waxes, for example, such as the product sold by the company Sophim under the reference M82. 
     The non-silicone solid fatty substance(s) may be present in the composition in an amount ranging from 0.1% to 10%, for example from 0.5% to 5% and further, for example, from 1% to 4% by weight relative to the total weight of the composition. 
     The composition according to the present disclosure may optionally contain other surfactants in addition to the above-described compounds of the present disclosure. 
     The additional surfactants may be present in an amount ranging from about 0.1% to 10%, for example from 0.5% to 8% and even further, for example, from 1% to 5% by weight relative to the total weight of the composition. 
     In at least one embodiment, the additional surfactants may be chosen from nonionic surfactants. 
     Nonionic surfactants are compounds that are well known per se (see, e.g., in this respect “Handbook of Surfactants” by M. R. Porter, published by Blackie &amp; Son (Glasgow and London), 1991, pp. 116-178) and, in the context of the present disclosure, the nature of the non-ionic surfactants is not a critical feature. Thus, they can be chosen from but are not limited to polyethoxylated, polypropoxylated or polyglycerolated fatty alcohols, polyethoxylated, polypropoxylated or polyglycerolated α-diols, polyethoxylated, polypropoxylated or polyglycerolated alkylphenols, and polyethoxylated, polypropoxylated or polyglycerolated fatty acids, all these compounds having a fatty chain containing, for example, 8 to 18 carbon atoms, it being possible for the number of ethylene oxide or propylene oxide groups to range from 2 to 50 and for the number of glycerol groups to range from 2 to 30. Non-limiting mention may also be made of copolymers of ethylene oxide and of propylene oxide, condensates of ethylene oxide and of propylene oxide with fatty alcohols; polyethoxylated fatty amides for instance having from 2 to 30 mol of ethylene oxide, polyglycerolated fatty amides containing on average 1 to 5, for example 1.5 to 4, glycerol groups; oxyethylenated fatty acid esters of sorbitan having from 2 to 30 mol of ethylene oxide; fatty acid esters of sucrose, fatty acid esters of polyethylene glycol, alkylpolyglycosides, N-alkylglucamine derivatives, amine oxides such as (C 10 -C 14 )-alkylamine oxides or N-acylaminopropylmorpholine oxides. 
     The compositions according to the present disclosure include, in at least one embodiment, non-washing (non-detergent) compositions, and may comprise less than 4% by weight of detergent surfactants, such as anionic surfactants, relative to the total weight of the composition and further, for example, less than 1% by weight. In a further embodiment, the composition as disclosed herein does not contain any detergent surfactants. 
     The composition according to the present disclosure may also comprise at least one additional conditioning agent. This conditioning agent may be chosen from silicones, cationic polymers, liquid carboxylic fatty esters, plant oils and hydrocarbon-based oils, and mixtures thereof. 
     The silicones that may be used in accordance with the present disclosure may be soluble or insoluble in the composition, and, for example, they may be polyorganosiloxanes that are insoluble in the composition of the present disclosure. They may be in the form of oils, waxes, resins or gums. They may be used pure or as an emulsion, a dispersion or a microemulsion. 
     The organopolysiloxanes are defined in greater detail in Walter Noll&#39;s “Chemistry and Technology of Silicones” (1968) Academic Press. They can be volatile or non-volatile. 
     When they are volatile, the silicones may be chosen from those having a boiling point of between 60° C. and 260° C. For example the silicones may be chosen from: 
     (i) cyclic silicones containing from 3 to 7, for example 4 to 5, silicon atoms. These are, for example, octamethylcyclotetrasiloxane such as those sold under the name “Volatile Silicone 7207” by Union Carbide or “Silbione 70045 V 2” by Rhodia, decamethylcyclopentasiloxane sold under the name “Volatile Silicone 7158” by Union Carbide, and “Silbione 70045 V 5” by Rhodia, and mixtures thereof. 
     Non-limiting mention may also be made of cyclocopolymers of the dimethylsiloxane/methylalkylsiloxane type, such as “Silicone Volatile FZ 3109” sold by the company Union Carbide, having the chemical structure: 
     
       
         
         
             
             
         
       
     
     Non-limiting mention may also be made of mixtures of cyclic silicones with organosilicon compounds, such as the mixture of octamethylcyclotetrasiloxane and tetratrimethylsilylpentaerythritol (50/50) and the mixture of octamethylcyclotetrasiloxane and oxy-1,1′-bis(2,2,2′,2′,3,3′-hexatrimethylsilyloxy)neopentane; 
     (ii) linear volatile silicones containing 2 to 9 silicon atoms and having a viscosity of less than or equal to 5×10 −6  m 2 /s at 25° C. An example is decamethyltetrasiloxane sold under the name “SH 200” by the company Toray Silicone. Silicones belonging to this category are also described in the article published in Cosmetics and Toiletries, Vol. 91, January 76, pp. 27-32, Todd &amp; Byers “Volatile Silicone Fluids for Cosmetics”. 
     The non-volatile silicones that may be mentioned include but are not limited to polyalkylsiloxanes, polyarylsiloxanes, polyalkylarylsiloxanes, silicone gums and resins, polyorganosiloxanes modified with organofunctional groups, and also mixtures thereof. 
     The organo-modified silicones that can be used in accordance with the present disclosure are silicones as defined above and containing in their structure one or more organo-functional groups attached via a hydrocarbon-based group. 
     Among the organomodified silicones, non-limiting mention may be made of polyorganosiloxanes comprising:
         polyethyleneoxy and/or polypropyleneoxy groups optionally comprising C 6 -C 24  alkyl groups, such as the products known as dimethicone copolyol sold by the company Dow Corning under the name DC 1248 or the oils Silwet® L 722, L 7500, L 77 and L 711 by the company Union Carbide, and the (C 12 )alkylmethicone copolyol sold by the company Dow Corning under the name Q2 5200;   substituted or unsubstituted amine groups, such as the products sold under the name GP 4 Silicone Fluid and GP 7100 by the company Genesee, or the products sold under the names Q2 8220 and Dow Corning 929 or 939 by the company Dow Corning. The substituted amine groups are, for instance, C 1 -C 4  aminoalkyl groups;   thiol groups, such as the products sold under the names “GP 72 A” and “GP 71” from Genesee;   alkoxylated groups, such as the product sold under the name “Silicone Copolymer F-755” by SWS Silicones and Abil Wax® 2428, 2434 and 2440 by the company Goldschmidt;   hydroxylated groups, such as the polyorganosiloxanes containing a hydroxyalkyl function, described in French Patent Application FR-A-85/16334;   acyloxyalkyl groups, such as, for example, the polyorganosiloxanes described in U.S. Pat. No. 4,957,732;   anionic groups of the carboxylic acid type, such as, for example, in the products described in European Patent EP 186 507 from the company Chisso Corporation, or of the alkylcarboxylic type, such as those present in the product X-22-3701 E  from the company Shin-Etsu; 2-hydroxyalkyl sulfonate; 2-hydroxyalkyl thiosulfate such as the products sold by the company Goldschmidt under the names “Abil® S201” and “Abil® S255”;   hydroxyacylamino groups, such as the polyorganosiloxanes described in European Patent Application EP 342 834. Non-limiting mention may be made, for example, of the product Q2-8413 from the company Dow Corning.       

     Examples of silicones that may be used include but are not limited to polydimethylsiloxanes, polyalkylarylsiloxanes and polydimethylsiloxanes containing amino or alkoxylated groups. 
     The additional conditioning agents may be present in the composition according to the present disclosure in an amount ranging from 0.01% to 20% by weight, for instance ranging from 0.1% to 10% by weight and further for example ranging from 0.3% to 5% by weight relative to the total weight of the composition. 
     The cosmetically acceptable medium is aqueous, for instance, and may comprise water or a mixture of water and a cosmetically acceptable solvent such as a C 1 -C 4  lower alcohol, for example ethanol, isopropanol, tert-butanol or n-butanol; polyols, for instance propylene glycol or glycerol; polyol ethers; C 5 -C 10  alkanes; and mixtures thereof. 
     In at least one embodiment, the solvents may be chosen from glycerol and propylene glycol. 
     The cosmetically acceptable medium, which is aqueous in at least one embodiment, is present in an amount ranging from 30% to 98% by weight relative to the total weight of the composition. 
     In at least one embodiment, the solvents are present in concentrations ranging from 0.5% to 30% by weight relative to the total weight of the composition. 
     The pH of the compositions of the present disclosure is from 2 to 8, and further for example from 3 to 7. 
     The compositions according to the present disclosure may also contain standard additives that are well known in the art, such as anionic, nonionic or amphoteric polymers, non-polymeric thickeners, for instance acids or electrolytes, opacifiers, nacreous agents, vitamins, provitamins such as panthenol, fragrances, dyes, organic or mineral particles, preserving agents, pH stabilizers, antidandruff agents, for instance piroctone olamine, hair-loss counteractants, grease-control agents and calmatives. 
     A person skilled in the art will take care to select the optional additives and the amount thereof such that they do not harm the properties of the compositions of the present disclosure. 
     These additives are present in the composition according to the present disclosure in an amount ranging from 0% to 20% by weight relative to the total weight of the composition. 
     The compositions of the present disclosure may be in the form of a rinse-out or leave-in hair conditioner, compositions for permanent-waving, relaxing, dyeing or bleaching, or alternatively in the form of rinse-out compositions to be applied before or after a dyeing, bleaching, permanent-waving or relaxing operation or alternatively between the two steps of a permanent-waving or hair-relaxing operation. 
     They may be used, for example, as hair conditioners, care products, deep-down care masks or scalp treatment lotions or creams. These compositions may be rinse-out or leave-in compositions. 
     According to at least one embodiment of the present disclosure, the composition may be used as a hair conditioner, for instance, a hair conditioner that can be used on sensitized hair. This hair conditioner may be a rinse-out or leave-in hair conditioner, and in at least one embodiment is a rinse-out hair conditioner. 
     The cosmetic compositions according to the present disclosure may be in the form of a gel, a milk, a cream, an emulsion, fluid or thickened lotions or a foam, and may be used for the skin, the nails, the eyelashes, the lips, and the hair, for example. 
     The compositions may be packaged in various forms, for instance in vaporizers, pump-dispenser bottles or in aerosol containers in order to dispense the composition in vaporized form or in the form of a mousse. Such packaging forms are indicated, for example, when it is desired to obtain a spray, a lacquer or a mousse for treating the hair. 
     The present disclosure also relates to a cosmetic process for treating keratin materials such as, for example, the skin or the hair, which comprises applying to the keratin materials an effective amount of a cosmetic composition as described above, and optionally rinsing it off after optionally leaving it to act for a period of time. 
     The rinsing is performed, for example, with water. 
     Thus, this process according to the present disclosure allows the treatment, conditioning and care of the hair or any other keratin material. 
     Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present disclosure. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should be construed in light of the number of significant digits and ordinary rounding approaches. 
     Notwithstanding the numerical ranges and parameters setting forth the broad scope of the disclosure are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in its respective testing measurement. 
     The examples that follow are intended to illustrate the present disclosure without, however, being limiting in nature. 
    
    
     EXAMPLES 
     Examples 1 to 4 
     The following rinse-out hair-conditioning compositions were prepared:
     1. All water was introduced into the manufacturing tank, and the water-soluble compounds were then added, with the exception of the oxyethylenated sorbitan ester(s). The mixture was heated to 80° C. with stirring using a doctor blade, until fully dissolved.   2. The water-insoluble compounds were introduced apart from the fragrances and the silicones into an additional tank. The mixture was heated to 80° C.   3. The contents of the additional tank and the silicones, if any, were introduced into the manufacturing tank and emulsified for 10 minutes with a vigorous turbomixer and doctor blade stirring, while the temperature was maintained. Then, the mixture was cooled.   4. At 30° C., the oxyethylenated sorbitan ester and the fragrances were introduced with doctor blade stirring.
