Description: HAIR CARE COMPOSITION CONTAINING A POLYALKYLENE(n)ALKYLAMINE WHICH PROVIDE HAIR VOLUME REDUCTION CROSS REFERENCE This application claims priority to international application PCT/US00/06666, filed in English, 14 March 2000, designating all countries, including the US. FIELD OF THE INVENTION The present invention relates to a hair care composition containing a polyalkylene(n)alkylamine which provides hair volume reduction. BACKGROUND OF THE INVENTION Human hair becomes soiled due to its contact with the surrounding environment and from sebum secreted by the scalp. The soiling of the hair causes it to have a dirty or greasy feel, and an unattractive appearance. The soiling of the hair necessitates shampooing with regularity. Shampooing cleans the hair by removing excess soil and sebum. However, shampooing can leave hair in a wet, tangled, and generally unmanageable state. After shampooing, hair is often left in a dry, rough, lusterless, or frizzy condition due to removal of the hair's natural oils and other natural conditioning and moisturizing components. The hair can further be left with increased levels of static upon drying which can interfere with combing and result in a condition commonly referred to as "flyaway hair." Certain consumers consider such flyaway hair and the corresponding increase in total hair volume undesirable. Thus, it is desirable to provide smooth, soft, silky-feeling, and healthy-looking hair, while decreasing flyaway hair volume and total hair volume. In addition, it is typically desirable to increase the biodegradability of a hair care composition. A variety of approaches have been developed to address these issues. Such approaches typically seek to increase smoothness, softness, and luster by including hair conditioning compounds, typically cationic compounds, such as cationic surfactants, into a hair care composition. Such hair conditioning compounds may also reduce static. In theory, these cationic compounds, including quaternary ammonium compounds, seek to neutralize the static charge on the hair, and thus reduce flyaway hair volume to a certain degree. However, these hair conditioning compounds do not sufficiently reduce total hair volume, and may be harsh on the hair, skin, or scalp. Accordingly, there exists a need for a hair care composition which effectively deposits onto hair to noticeably reduce total hair volume by reducing both bulk hair volume and flyaway hair volume. There also exists a need for a hair care composition which provides improved mildness to the hair, skin and scalp, and has improved biodegradability. SUMMARY OF THE INVENTION The present invention relates to a hair care composition including a a polyalkyleneglycol(n)alkylamine of the formula (I), (II), or mixtures thereof: R— N — tC m H 2m O) x H (C n H 2 nO) Y H (i) wherein each R is independently a saturated, unsaturated, straight or branched alkyl group having from 1 to about 30 carbon atoms, R' is a saturated, unsaturated, straight or branched alkyl group having from 1 to about 4 carbon atoms, each m is 2 or 3, each n is 2 or 3, each x and each y are independently a number of 1 or more wherein the sum of each x and each y is from about 3 to about 9; and wherein X " is any safe and suitable salt forming anion selected from the group consisting of chloride, bromide, iodide, acetate, citrate, lactate, glycolate, phosphate, nitrate, sulfonate, sulfate, alkylsulfate, alkyl sulfonate, glutamate aspartate, and mixtures thereof; and wherein the melting point of the polyalkyleneglycoI(n)alkylamine is less than about 45°C; and a suitable carrier; wherein the composition reduces bulk hair area by at least about 10%, according to an Image Analysis Protocol. It has now been found that total hair volume is actually the sum of the "flyaway hair volume" and the "bulk hair volume." It has also been found that a measurable reduction of bulk hair area, flyaway hair area, and total hair area, by the Image Analysis Protocol described herein, corresponds to a noticeable decrease in the bulk hair volume, flyaway hair volume, and the total hair volume, respectively. Accordingly, it has been found that reducing the bulk hair area can therefore play a significant role in reducing the total hair volume. While certain compounds and compositions are known to reduce fly-away hair volume, for example, by reducing the static charge of hair, these compositions do not noticeably reduce bulk hair volume. It has now been found that a hair care composition which moisturizes the hair may noticeably reduce bulk hair volume, and may also noticeably reduce flyaway hair volume. This, in turn, provides a significant, noticeable reduction in total hair volume. It has now been found that a hair care composition, preferably a hair conditioning composition, and/or a styling composition, containing a polyalkyleneglycol(n)alky!amine and a gel matrix may effectively deposit onto hair, and provide significant consumer-desirable benefits, such as an improved look and feel for hair, reduced bulk hair volume, reduced flyaway hair volume, and reduced total hair volume. Furthermore, the hair care composition is stable upon addition of oily components, provides improved mildness to the hair, skin and scalp, and has improved biodegradability. These and other features, aspects, advantages, and variations of the present invention, and the embodiments described herein, will become evident to those skilled in the art from a reading of the present disclosure with the appended claims, and are covered within the scope of these claims. BRIEF DESCRIPTION OF THE FIGURE While the specification concludes with claims particularly pointing out and distinctly claiming the invention, it is believed that the invention will be better understood from the following description of the accompanying figure in which: Fig. 1 is a top view of a preferred embodiment of the Image Analysis System. DETAILED DESCRIPTION OF THE INVENTION All percentages, ratios and proportions herein are by weight of the final hair care composition, unless otherwise specified. All molecular weights herein are weight average molecular weights, unless otherwise specified. All temperatures are in degrees Celsius (°C) unless otherwise specified. All documents cited are incorporated herein by reference in their entireties. Citation of any reference is not an admission regarding any determination as to its availability as prior art to the claimed invention. The drawing herein is not necessarily drawn to scale. As used herein, the term "alkyl" means a hydrocarbyl moiety which is straight, branched, or cyclic, saturated or unsaturated. Unless otherwise specified, alkyl moieties are preferably saturated or unsaturated with double bonds, preferably with one or two double bonds. Included in the term "alkyl" is the alkyl portion of acyl groups. As used herein, the term "hair conditioning benefit" indicates a conditioning, softening, bulk hair volume reduction, flyaway hair volume reduction, total hair volume reduction, moisturizing, improved wet-hair or dry-hair feel, lubricating, smoothening, softening, and/or other effect when applied to hair. All reductions in bulk hair volume, flyaway hair volume, and/or total hair volume are according to the Image Analysis Protocol, as described herein. As used herein, the term "water-insoluble" means the compound is substantially not soluble in water at 25°C, when the compound is mixed with water at a concentration by weight of above 1.0%, preferably at above 0.5%, the compound is temporarily dispersed to form an unstable colloid in water, then is quickly separated from water into two phases. POLYALKYLENEGLYCOL(n)ALKYLAMINE The hair care composition of the present invention contains a polyalkyleneglycol(n)alkylamine which is substantially liquid at room temperature, typically having a melting point of less than about 45°C, more preferably less than about 30°C. Without intending to be limited by theory, it is believed that the polyalkyleneglycol(n)alkylamine useful herein provide a bulk hair volume reduction benefit by the following mechanism: The amino and hydrophobic alkyl moieties help the compound to attach to hair fibers, even under rinse-off conditions, while the hydrophilic alkoxylate groups attract water molecules and function as a moisture buffer to slow down water content change in the hair fibers. This helps maintain the hair fibers in a flexible, soft, and plastic state. This in turn, allows the hair fiber to maintain a well-aligned conformation (with respect to other hair fibers) and to easily recover from deformation. This further increases the likelihood that the hair fibers will remain parallel, and/or hang straight down. This significantly reduces the space between the individual hair fibers, and therefore reduces both bulk hair volume and flyaway hair volume. Without intending to be limited by theory, it is also believed that the polyalkyleneglycol(n)alkylamine may reduce flyaway hair volume as well. It is believed that the amine moieties of the polyalkyleneglycol(n)alkylamine are slightly positively charged in an aqueous carrier or a lower pH environment, thus, is attracted and well deposited on the surface of the hair. Thus, together with the moisturizing effect to the hair fiber, the polyalkyleneglycol(n)alkylamine may also reduce the hair fiber's static charge and crookedness. This reduces the electrostatic repulsion and space between hair fibers, which leads to a reduction in flyaway hair volume. The polyalkyleneglycol(n)alkylamine useful in the present invention has a general formula (I), (II), or is a mixture of the two: K N ~- TC m H 2 mO) x H (C n H 2n O)yH (I) wherein each R is independently a saturated, unsaturated, straight or branched alkyl group having from 1 to about 30 carbon atoms, preferably from about 8 to about 22 carbon atoms, more preferably from about 10 to about 18 carbon atoms; R' is a saturated, unsaturated, straight or branched alkyl group having from 1 to about 4 carbon atoms, preferably hydrogen, methyl or ethyl; each m is 2 or 3, preferably 2; each n is 2 or 3, preferably 2; each x and each y are independently a number of 1 or more wherein the sum of each x and each y is from about 3 to about 9, preferably from 4 to 6, and X " is any safe and suitable salt forming anion such as chloride, bromide, iodide, acetate, citrate, lactate, glycolate, phosphate, nitrate, sulfonate, sulfate, alkylsulfate, alkyl sulfonate, glutamate and aspartate radicals. Preferred polyalkyleneglycol(n)alkylamines are those having general formula (I). Compounds of general formula (I) are typically used in combination with an acid to provide the cationic species. The preferred acid useful herein includes L-glutamic acid, lactic acid, hydrochloric acid, malic acid, succinic acid, acetic acid, fumaric acid, tartaric acid, citric acid, L-glutamic hydrochloride, L- aspartic acid, and mixtures thereof. The molar ratio of protonatable amines to H + from the acid is preferably from about 1 :0.3 to 1 :1.2. Highly suitable polyalkyleneglycol(n)alkylamines are polyethyleneglycol(n)alkylamines wherein both m and n are about 2. Highly preferred polyethyleneglycol(n)alkylamines useful in the present invention are polyethyleneglycol-5-oleylamine, also abbreviated as PEG-5 oleylamine, wherein the sum of x and y is about 5; and polyethyleneglycol-5- cocamine also abbreviated as PEG-5 cocamine, wherein R is substantially made of straight chain alkyls having 10-16 carbon atoms, and the sum of x and y is about 5. The polyalkyleneglycol(n)alkylamine is preferably present at a level of from about 0.1% to about 5%, more preferably from about 0.4% to about 3%, and still preferably from about 0.5% to about 2%, by weight of the hair care composition. Particularly preferable and commercially available polyalkylenegIycol(n)alkylamines are; PEG-5-oleylamine with tradename Varonic Q-205, and PEG-5-cocamine with tradename Varonic K-205, both available from Th. Goldschmidt AG. SUITABLE CARRIER The suitable carrier contains a continuous phase, which is typically either water, or liquid hydrophobic material such as liquid fatty alcohol and acid, liquid hydrocarbon, liquid silicone materials, and mixtures thereof. The continuous phase is preferably water, but even a water continuous phase may also contain an oil emulsified, or dispersed therein, and visa-versa. Other carrier ingredients and/or other additional components may also be added into the suitable carrier. Without intending to be limited by theory, it is believed that the polyalkylene(n)alkylamine of the present invention deposit especially well onto hair when included in a suitable carrier, such as an aqueous carrier. It is believed that their combination of bulkiness, branching, and high molecular weight contribute significantly to their deposition and effectiveness, even in the absence of a gel matrix. Thus, while a gel matrix is preferred, the polyalkylene(n)alkylamine herein provide significant, desirable benefits, even in the absence of a gel matrix. GEL MATRIX The suitable aqueous carrier useful herein is a gel matrix. Preferably, the gel matrix is comprised, by weight of the hair care composition, from about 60% to about 99%, preferably from about 70% to about 95%, and more preferably from about 80% to about 95%. The gel matrix includes a cationic surfactant, a solid fatty compound, and water. The gel matrix serves as an aqueous carrier for the alkyl ethoxylate, and is typically characterized by a viscosity of from about 5,000 cps to about 40,000 cps, preferably from about 10,000 cps to about 30,000 cps, and more preferably from about 12,000 cps to about 28,000 cps, as measured at 25 °C, by means of a Brookfield Viscometer at shear rate of 1.0 rpm. Without intending to be limited by theory, it is believed that the gel matrix significantly improves deposition of the alkyl ethoxylate onto hair. In a highly preferred embodiment, the gel matrix is a lamellar gel matrix, which provides improved deposition, wet hair feel, softness, and other substantial benefits. In a lamellar gel matrix, the weight ratio of cationic surfactant to solid fatty compound is from about 1 :1 to about 1 :20, preferably from about 1:2 to about 1:10, and more preferably form about 1 :3 to 1 :5. Generally, the preferred cationic surfactants in the lamellar gel matrix contain one or two long chain (e.g., C 12 . 30 ) alkyl groups, and a tertiary or quaternary amine group. Tertiary amine groups having one or two C 16 . 22 alkyl chains are preferred. The existence of a lamellar gel matrix may be detected by differential scanning calorimetry (hereinafter referred to as "DSC") measurement of the composition. A profile chart obtained by DSC measurement describes chemical and physical changes of the scanned sample that involve an enthalpy change or energy gradient when the temperature of the sample is fluctuated. As such, the phase behavior and interaction among components of hair conditioning compositions of the present invention may be understood by their DSC profiles. DSC measurement of compositions of the present invention may be conducted by any suitable instrument available. For example, DSC measurement may be suitably conducted by Seiko DSC 6000 instrument available from Seiko Instruments Inc. In a typical measurement procedure, a sample is prepared by sealing an appropriate amount of the composition into a container made for DSC measurement and sealed. The weight of the sample is recorded. A blank sample i.e.; an unsealed sample of the same container is also prepared. The sample and blank sample are placed inside the instrument, and run under a measurement condition of from about -50°C to about 130°C at a heating rate of from about 1 °C/minute to about 10°C/minute. The area of the peaks as identified are calculated and divided by the weight of the sample to obtain the enthalpy change in mJ/mg. In a preferred lamellar gel matrix, the DSC profile shows a formation peak of larger than about 3 mJ/mg. The position of the peaks are identified by the peak top position. The DSC profile of the preferred lamellar gel matrix shows a single peak having a peak top temperature of from about 55°C to about 75°C, and from about 6 mJ/mg to about 10 mJ/mg. The preferred DSC profile of the lamellar gel matrix shows no peaks larger than 3 mJ/mg from 40°C to 55°C. It is believed that a composition formed predominantly with such a gel matrix shows a relatively stable phase behavior during the temperature range of from about 40°C to about 55°C. In an even more preferred lamellar gel matrix, the DSC profile shows a single peak having a peak top temperature of between about 60°C and 70°C, at about 8 mJ/mg, and no peaks larger than 3 mJ/mg from 40°C to about 55°C. The gel matrix may become unstable or, at worst, become destroyed in the presence of certain components. Such components include high levels of anionic surfactants and film-forming polymers having anionic moieties. A highly preferred composition is substantially free of such components. a.

Solid Fatty Compound The solid fatty compound useful herein has a melting point of 25°C or higher, and is selected from the group consisting of fatty alcohols, fatty acids, and mixtures thereof. It is understood by the artisan that the compounds disclosed in this section of the specification can in some instances fall into more than one classification, e.g., some fatty alcohol derivatives may also be classified as fatty acid derivatives. However, a given classification is not intended to be a limitation on that particular compound, but is done so for convenience of classification and nomenclature. Further, it is understood by the artisan that, depending on the number and position of double bonds, and length and position of the branches, certain compounds having certain required carbon atoms may have a melting point of less than 25°C. Such compounds of low melting point are not intended to be included in this section. Nonlimiting examples of the high melting point compounds are found in International Cosmetic Ingredient Dictionary, Fifth Edition, 1993, and CTFA Cosmetic Ingredient Handbook, Second Edition, 1992. The solid fatty compound is included in the composition at a level by weight of from about 0.1 % to about 20%, preferably from about 1 % to about 15%, more preferably from about 2% to about 10%. The fatty alcohols useful herein are those having from about 14 to about 30 carbon atoms, preferably from about 16 to about 22 carbon atoms. These fatty alcohols are saturated and can be straight or branched chain alcohols. Nonlimiting examples of fatty alcohols include, cetyl alcohol, stearyl alcohol, behenyl alcohol, and mixtures thereof. The fatty acids useful herein are those having from about 10 to about 30 carbon atoms, preferably from about 12 to about 22 carbon atoms, and more preferably from about 16 to about 22 carbon atoms. These fatty acids are saturated and can be straight or branched chain acids. Also included are diacids, triacids, and other multiple acids which meet the requirements herein. Also included herein are salts of these fatty acids. Nonlimiting examples of fatty acids include lauric acid, palmitic acid, stearic acid, behenic acid, sebacic acid, and mixtures thereof. Solid fatty compounds of a single compound of high purity are preferred. Single compounds of pure fatty alcohols selected from the group of pure cetyl alcohol, stearyl alcohol, and behenyl alcohol are highly preferred. By "pure" herein, what is meant is that the compound has a purity of at least about 90%, preferably at least about 95%. These single compounds of high purity may provide good rinsability from the hair when the consumer rinses off the composition. Commercially available solid fatty compounds useful herein include: cetyl alcohol, stearyl alcohol, and behenyl alcohol having tradenames KONOL series available from Shin-nihon Rika (Osaka, Japan), and NAA series available from NOF (Tokyo, Japan); pure behenyl alcohol having tradename 1-DOCOSANOL available from Wako Chemical (Osaka, Japan), various fatty acids having tradenames NEO-FAT available from Akzo (Chicago, Illinois, USA), HYSTRENE available from Witco Corp. (Dublin, Ohio, USA), and DERMA available from Vevy (Genova, Italy). While poly fatty alcohols may form the gel matrix, mono fatty alcohols are preferred. Either the cationic surfactant, and/or the solid fatty compound may be first mixed with, suspended in, and/or dissolved in water when forming a gel matrix. c. Water The final hair care composition of the present invention typically comprises at least about 60%, preferably at least about 70% water, and more preferably from about 75% to about 95% water. Deionized water is preferably used. Water from natural sources including mineral cations may also be used, depending on the desired characteristic of the product. POLYPROPYLENE GLYCOL The hair care composition of the present invention preferably contains a polypropylene glycol having a weight average molecular weight of from about 200 g/mol to about 100,000 g/mol, preferably from about 1 ,000 g/mol to about 60,000 g/mol. Without intending to be limited by theory, it is believed that the polypropylene glycol herein deposits onto, or is absorbed into hair to act as a moisturizer buffer, and/or provides one or more other desirable hair conditioning benefits. As used herein, the term "polypropylene glycol" includes single- polypropylene glycol-chain segment polymers, and multi-polypropylene glycol- chain segment polymers. The general structure of branched polymers such as the multi-polypropylene glycol-chain segment polymers herein are described, for example, in "Principles of Polymerization," pp. 17-19, G. Odian, (John Wiley & Sons, Inc., 3 rd ed., 1991). The polypropylene glycol herein are typically polydisperse polymers. The polypropylene glycols useful herein have a polydispersity of from about 1 to about 2.5, preferably from about 1 to about 2, and more preferably from about 1 to about 1.5. As used herein, the term "polydispersity" indicates the degree of the molecular weight distribution of the polymer sample. Specifically, the polydispersity is a ratio, greater than 1 , equal to the weight average molecular weight divided by the number average molecular weight. For a further discussion about polydispersity, see "Principles of Polymerization," pp. 20-24, G. Odian, (John Wiley & Sons, Inc., 3 rd ed., 1991). The polypropylene glycol useful herein may be either water-soluble, water- insoluble, or may have a limited solubility in water, depending upon the degree of polymerization and whether other moieties are attached thereto. The desired solubility of the polypropylene glycol in water will depend in large part upon the form (e.g., leave-on, or rinse-off form) of the hair care composition. The solubility in water of the polypropylene glycol herein may be chosen by the artisan according to a variety of factors. Accordingly, for a leave-on hair care composition, it is preferred that the polypropylene glycol herein be a water- soluble polypropylene glycol. Solubility information is readily available from polypropylene glycol suppliers, such as Sanyo Kasei (Osaka, Japan). However, the present invention may also take the form of a rinse-off hair care composition. Without intending to be limited by theory, it is believed that in such a composition, a water-soluble polypropylene glycol may be too easily washed away before it effectively deposits on hair and provides the desired benefit(s). For such a composition, a less soluble, or even a water-insoluble polypropylene glycol is therefore preferred.

The HLB value is a theoretical index value which describes the hydrophilicity-hydrophobicity balance of a specific compound.

The HLB value of the alkyl ethoxylate may be found in tables and charts known in the art, or may be calculated with the following general equation: HLB = 7 + ∑(hydrophobic group values) + ∑(hydrophilic group values). The HLB and methods for calculating the HLB of a compound are explained in detail in "Surfactant Science Series, Vol. 1 : Nonionic Surfactants", pp. 606-13, M. J. Schick (Marcel Dekker, Inc., New York, 1966).

As is well understood in the art, the degree of crosslinking that is required in order to result in a silicone resin will vary according to the specific silane units incorporated into the silicone resin. In general, silicone materials which have a sufficient level of trifunctional and tetrafunctional siloxane monomer units, and hence, a sufficient level of crosslinking, such that they dry down to a rigid, or hard, film are considered to be silicone resins. The ratio of oxygen atoms to silicon atoms is indicative of the level of crosslinking in a particular silicone material. Silicone materials which have at least about 1.1 oxygen atoms per silicon atom will generally be silicone resins herein. Preferably, the ratio of oxygen:silicon atoms is at least about 1.2:1.0. Silanes used in the manufacture of silicone resins include monomethyl-, dimethyl-, trimethyl-, monophenyl-, diphenyl-, methylphenyl-, monovinyl-, and methylvinylchlorosilanes, and tetrachlorosilane, with the methyl substituted silanes being most commonly utilized. Preferred resins are offered by General Electric as GE SS4230 and SS4267. Commercially available silicone resins will generally be supplied in a dissolved form in a low viscosity volatile or nonvolatile silicone fluid. The silicone resins for use herein should be supplied and incorporated into the present compositions in such dissolved form, as will be readily apparent to those skilled in the art. Without being bound by theory, it is believed that the silicone resins can enhance deposition of other silicone compounds on the hair and can enhance the glossiness of hair with high refractive index volumes. Other useful silicone resins are silicone resin powders such as the material given the CTFA designation polymethylsilsequioxane, which is commercially available as Tospearl™ from Toshiba Silicones. The method of manufacturing these silicone compounds, can be found in Encyclopedia of Polymer Science and Engineering, Volume 15, Second Edition, pp. 204-308, John Wiley & Sons, Inc., 1989. Silicone materials and silicone resins in particular, can conveniently be identified according to a shorthand nomenclature system well known to those skilled in the art as the "MDTQ" nomenclature. Under this system, the silicone is described according to the presence of various siloxane monomer units which make up the silicone. Briefly, the symbol M denotes the mono-functional unit (CH 3 ) 3 SiO 5 ; D denotes the difunctional unit (CH 3 ) 2 SiO; T denotes the trifunctional unit (CH 3 )SiO 1 5 ; and Q denotes the quadri- or tetra-functional unit SiO2. Primes of the unit symbols, e.g., M', D', T', and Q' denote substituents other than methyl, and must be specifically defined for each occurrence. Typical alternate substituents include groups such as vinyl, phenyl, amino, hydroxyl, etc. The molar ratios of the various units, either in terms of subscripts to the symbols indicating the total number of each type of unit in the silicone, or an average thereof, or as specifically indicated ratios in combination with the weight average molecular weight, complete the description of the silicone material under the MDTQ system. Higher relative molar amounts of T, Q, T' and/or Q' to D, D', M and/or or M' in a silicone resin is indicative of higher levels of crosslinking. As discussed before, however, the overall level of crosslinking can also be indicated by the oxygen to silicon ratio. The silicone resins for use herein which are preferred are MQ, MT, MTQ, MQ and MDTQ resins. Thus, the preferred silicone substituent is methyl. Especially preferred are MQ resins wherein the M:Q ratio is from about 0.5:1.0 to about 1.5:1.0 and the weight average molecular weight of the resin is from about 1000 to about 10,000. Commercially available silicone compounds which are useful herein include Dimethicone with tradename D-130, cetyl Dimethicone with tradename DC2502, stearyl Dimethicone with tradename DC2503, emulsified polydimethyl siloxanes with tradenames DC1664 and DC1784, and alkyl grafted copolymer silicone emulsion with tradename DC2-2845; all available from Dow Corning Corporation (Midland, Michigan, USA), emulsion polymerized Dimethiconol available from Toshiba Silicone Co., Ltd. (Tokyo, Japan) as described in GB application 2,303,857, mixture of Dimethicone and Dimethiconol with tradename DCQ2-1403, and mixture of Cyclomethicone and Dimethiconol with tradename DRQ2-1401 , both mixtures available from Dow Corning. Cationic Polymer The hair care compositions of the present invention may contain one or more cationic polymers. As used herein, the term "polymer" includes materials whether made by polymerization of one type of monomer or made by two (i.e., copolymers) or more types of monomers. Preferably, the cationic polymer is a water-soluble cationic polymer. As used herein, the term "water soluble" cationic polymer, indicates a polymer which is sufficiently soluble in water to form a substantially clear solution to the naked eye at a concentration of 0.1% in water (distilled or equivalent) at 25°C. The preferred cationic polymer will be sufficiently soluble to form a substantially clear solution at 0.5% concentration, more preferably at 1.0% concentration. If present, the cationic polymer is typically at a level of preferably from about 0.5% to about 5%, more preferably from about 1 % to about 3% by weight of the composition. The cationic polymers herein will generally have a weight average molecular weight which is at least about 5,000, typically from about 10,000 to about 10 million. Preferably, the weight average molecular weight is from about 100,000 to about 2 million. The cationic polymer will generally have cationic nitrogen-containing moieties such as quaternary ammonium or cationic amino moieties, and mixtures thereof. The cationic nitrogen-containing moiety will be present generally as a substituent, on a fraction of the total monomer units of the cationic hair conditioning polymers. Thus, the cationic polymer may comprise copolymers, terpolymers, etc. of quaternary ammonium or cationic amine-substituted monomer units and other non-cationic units referred to herein as spacer monomer units. Such polymers are known in the art, and a variety may be found in the CTFA Cosmetic Ingredient Dictionary, 3rd edition, edited by Estrin, Crosley, and Haynes, (The Cosmetic, Toiletry, and Fragrance Association, Inc., Washington, D.C., 1982). The cationic charge density of the cationic polymer is preferably at least about 0.1 meq/gram, more preferably at least about 0.5 meq/gram, even more preferably at least about 1.1 meq/gram, and still more preferably at least about 1.2 meq/gram. Cationic charge density of the cationic polymer may be determined according to the Kjeldahl Method. Those skilled in the art will recognize that the charge density of amino-containing polymers may vary depending upon pH and the isoelectric point of the amino groups. The charge density should be within the above limits at the pH of intended use. Any anionic counterion may be utilized for the cationic polymers so long as the water solubility criteria is met. Suitable counter-ions include, for example, halides (e.g., Cl, Br, I, or F, preferably Cl, Br, or I), sulfate, and methylsulfate. Suitable cationic polymers include, for example, copolymers of vinyl monomers having cationic amine or quaternary ammonium functionalities with water soluble spacer monomers such as acrylamide, methacrylamide, alkyl and dialkyl acrylamides, alkyl and dialkyl methacrylamides, alkyl acrylate, alkyl methacrylate, vinyl caprolactone, and vinyl pyrrolidone. The cationic amines may be primary, secondary, or tertiary amines, depending upon the particular species and the pH of the composition. In general, secondary and tertiary amines, especially tertiary amines, are preferred. The alkyl and dialkyl substituted monomers preferably have C-] - C7 alkyl groups, more preferably C-j - C3 alkyl groups. Other suitable spacer monomers include vinyl esters, vinyl alcohol (made by hydrolysis of polyvinyl acetate), maleic anhydride, propylene glycol, and ethylene glycol. Amine-substituted vinyl monomers may be polymerized in the amine form, and then optionally may be converted to ammonium by a quaternization reaction. Amines may also be similarly quaternized subsequent to formation of the polymer. For example, tertiary amine functionalities may be quaternized by reaction with a salt of the formula R'X wherein R' is a short chain alkyl, preferably a Ci - C7 alkyl, more preferably a C1 - C3 alkyl, and X " is an anion which forms a water soluble salt with the quaternized ammonium. Suitable cationic amino and quaternary ammonium monomers include, for example, vinyl compounds substituted with dialkylaminoalkyl acrylate, dialkylaminoalkyl methacrylate, monoalkylaminoalkyl acrylate, monoalkylaminoalkyl methacrylate, trialkyl methacryloxyalkyl ammonium salt, trialkyl acryloxyalkyl ammonium salt, diallyl quaternary ammonium salts, and vinyl quaternary ammonium monomers having cyclic cationic nitrogen-containing rings such as pyridinium, imidazolium, and quaternized pyrrolidone, e.g., alkyl vinyl imidazolium, alkyl vinyl pyridinium, alkyl vinyl pyrrolidone salts. The alkyl portions of these monomers are preferably lower alkyls such as the Ci - C3 alkyls, more preferably Ci and C2 alkyls. Suitable amine-substituted vinyl monomers for use herein include dialkylaminoalkyl acrylate, dialkylaminoalkyl methacrylate, dialkylaminoalkyl acrylamide, and dialkylaminoalkyl methacrylamide, wherein the alkyl groups are preferably C-| - C7 hydrocarbyls, more preferably C-| - C3, alkyls. The cationic polymers useful herein may comprise mixtures of monomer units derived from amine- and/or quaternary ammonium-substituted monomer and/or compatible spacer monomers. Suitable cationic hair conditioning polymers include, for example: copolymers of 1-vinyl-2-pyrrolidone and 1-vinyl-3-methylimidazolium salt (e.g., chloride salt) (referred to in the industry by the Cosmetic, Toiletry, and Fragrance Association, "CTFA", as Polyquatemium-16), such as those commercially available from BASF Wyandotte Corp. (Parsippany, NJ, USA) under the LUVIQUAT tradename (e.g., LUVIQUAT FC 370); copolymers of 1-vinyl-2- pyrrolidone and dimethylaminoethyl methacrylate (referred to in the industry by CTFA as Polyquatemium-11) such as those commercially available from Gaf Corporation (Wayne, NJ, USA) under the GAFQUAT tradename (e.g., GAFQUAT 755N); cationic diallyl quaternary ammonium-containing polymers, including, for example, dimethyldiallylammonium chloride homopolymer and copolymers of acrylamide and dimethyldiallylammonium chloride, referred to in the industry (CTFA) as Polyquatemium 6 and Polyquatemium 7, respectively; and mineral acid salts of amino-alkyl esters of homo- and co-polymers of unsaturated carboxylic acids having from 3 to 5 carbon atoms, as described in U.S. Patent 4,009,256 issued to Nowack, et. al., on February 22, 1977. Other useful cationic polymers include cationic polysaccharide polymers, such as cationic cellulose derivatives and cationic starch derivatives. Cationic polysaccharide polymer materials suitable for use herein include those of the formula: wherein: A is an anhydroglucose residual group, such as a starch or cellulose anhydroglucose residual, R is an alkylene oxyalkylene, polyoxyalkylene, or hydroxyalkylene group, or combination thereof, Rl , R2, and R^ independently are alkyl, aryl, alkylaryl, arylalkyl, alkoxyalkyl, or alkoxyaryl groups, each group containing up to about 18 carbon atoms, and the total number of carbon atoms for each cationic moiety (i.e., the sum of carbon atoms in R1 , R2 and R^) preferably being about 20 or less, and X " is an anionic counterion, as previously described. Cationic cellulose is available from Amerchol Corp. (Edison, NJ, USA) in their Polymer JR® and LR® series of polymers, as salts of hydroxyethyl cellulose reacted with trimethyl ammonium substituted epoxide, referred to in the industry (CTFA) as Polyquatemium 10. Another type of cationic cellulose includes the polymeric quaternary ammonium salts of hydroxyethyl cellulose reacted with lauryl dimethyl ammonium-substituted epoxide, referred to in the industry (CTFA) as Polyquatemium 24. These materials are available from Amerchol Corp. (Edison, NJ, USA) under the tradename Polymer LM-200®. Other cationic polymers that may be used include cationic guar gum derivatives, such as guar hydroxypropyltrimonium chloride (commercially available from Celanese Corp. in their Jaguar R series). Other materials include quaternary nitrogen-containing cellulose ethers (e.g., as described in U.S. Patent 3,962,418, incorporated herein by reference), and copolymers of etherified cellulose and starch (e.g., as described in U.S. Patent 3,958,581 , incorporated herein by reference.) Other Additional Components The hair care compositions herein may further contain other additional components, which may be selected by the artisan according to the desired characteristics of the final product and which are suitable for rendering the compositions more cosmetically or aesthetically acceptable or to provide them with additional usage benefits. Additional examples of preferred other additional components which may be formulated into the present compositions include: other conditioning agents such as hydrolysed collagen with tradename Peptein 2000 available from Hormel, panthenol available from Roche, panthenyl ethyl ether available from Roche, hydrolysed keratin, proteins, herbal extracts such as Polygonatum multiflori extract, and nutrients; vitamins and/or amino acids, such as vitamin E with tradename Emix-d available from Eisai, tyrosine methyl ether, histidine, and lysine hydrochloride; surfactants such as a cationic surfactant, a nonionic surfactant, an amphoteric surfactant, and mixtures thereof; preservatives such as benzyl alcohol, methyl paraben, propyl paraben and imidazolidinyl urea; pH adjusting agents, such as citric acid, sodium citrate, succinic acid, phosphoric acid, sodium hydroxide, sodium carbonate; salts, in general, such as potassium acetate and sodium chloride; coloring agents, such as any of the FD&C or D&C dyes; hair oxidizing (bleaching) agents, such as hydrogen peroxide, perborate and persulfate salts; hair reducing agents such as the thioglycolates; perfumes; sequestering agents, such as disodium ethylenediamine tetra-acetate; ultraviolet and infrared screening and absorbing agents, such as optical brighteners and octyl salicylate; and antidandruff agents, such as zinc pyrithione, piroctone olamine, 3,4,4'- trichlorocarbanilide (trichlosan), triclocarban and salicylic acid. MANUFACTURING PROCESS The hair care compositions of the present invention can be conveniently and inexpensively by any process known in the art, and is preferably made by combining the polyalkyleneglycol(n)alkylamine with the gel matrix concurrently with the gel matrix, or after the gel matrix reaches a suitable phase condition. To form a highly preferred gel matrix, water is typically heated to at least about 70 °C, preferably between about 80°C and about 90°C. The cationic surfactant and the solid fatty compound are combined with the water to form a mixture. The polyalkyleneglycol(n)alkylamine can be added at this step, for a composition having improved stability. The temperature of the mixture is preferably maintained at a temperature higher than both the melting temperature of the cationic surfactant and the melting temperature of the solid fatty compound, and the entire mixture is homogenized. After mixing until no solids are observed, the mixture is gradually cooled (e.g., at a rate of about 2°C/minute) to a temperature below 60°C, preferably less than about 55°C. During this gradual cooling process, a significant viscosity increase is observed at between about 55°C and about 75°C. This indicates the formation of the highly preferred gel matrix. The polyalkyleneglycol(n)alkylamine can be alternatively added at this stage, with any other additional components, and mixed into the gel matrix, and cooled to room temperature. The hair care composition made by the above described processes containing the polyalkyleneglycol(n)alkylamine possesses good stability and excellent performance. METHOD OF USE The hair care composition of the present invention is suitable for use as, for example, hair cosmetic compositions, hair styling compositions, leave-on and/or rinse-off hair conditioning compositions. These hair care compositions are used in conventional ways to provide the conditioning, cleaning, styling, and/or other benefits of the present invention. Such method of use depends upon the type of composition employed but generally involves application of an effective amount of the product to the hair, which may then be rinsed from the hair (as in the case of hair rinses) or allowed to remain on the hair (as in the case of gels, lotions, and creams). "Effective amount" means an amount sufficient enough to provide the desired bulk hair reduction benefit. In general, from about 1 g to about 50 g is applied to the hair, and/or the scalp. The composition may be distributed throughout the hair, typically by rubbing or massaging the hair and scalp, or the composition may be selectively applied to certain parts of the hair. Preferably, the composition is applied to wet or damp hair and rinsed with abundant water prior to drying of the hair. After such compositions are applied to the hair, the hair is dried and styled in accordance with the preference of the user. In the alternative, such as for a hair styling composition, it may be applied to dry hair, and the hair is then combed or styled in accordance with the preference of the user. IMAGE ANALYSIS PROTOCOL The Image Analysis Protocol is a system and procedure which is designed to digitally measure and analyze the components of bulk hair area and flyaway hair area, which in turn form the total hair area. This protocol provides a quantifiable, repeatable method for accurately distinguishing, measuring, and comparing total hair area, flyaway hair area, and bulk hair area before and after treatment with a hair care composition. This total hair area, flyaway hair area, and bulk hair area directly correlate with total hair volume, flyaway hair volume, and bulk hair volume, respectively. The hair care compositions of the present invention provide a significant, noticeable reduction in the bulk hair area, preferably by at least about 10% as measured by the method described, below. The hair care compositions of the present invention preferably provide a significant, noticeable reduction in all three types of hair area, namely, reduces bulk hair area by at least about 10%, more preferably by at least about 15%, reduces flyaway hair area by at least about 20%, more preferably by at least about 30%, and reduces total hair area by at least about 12.5%, more preferably by at least about 20%, as measured by the method described, below. It has been found that a reduction in bulk hair area correlates with one or more noticeable consumer-desirable benefits, such as enhanced manageability, and/or improved combability. For example, it is believed that reduced bulk hair area correlates with moisturized hair which is softer, more plastic, smooth, and flexible than hair which is dried out. When hair is moisturized, the bulk hair area is reduced, because the hair is better aligned with other hairs and has less space in-between the individual hairs. Moisturized hair is also easier to comb and manage. Referring to the drawing, Fig. 1 shows a top view of a preferred embodiment of the Image Analysis System useful herein. The Image Analysis System, 10, consists of a white screen, 12, lighting equipment, 14, a sample holder, 16, a high-resolution digital camera, 18, and a personal computer, 20. The sample holder, 16, is placed between the white screen, 12, and the high- resolution digital camera, 18. The sample holder, 16, is typically a clip or clamp which stably suspends a hair sample, 22, about 40 cm in front of the white screen, 12. The sample holder, 16, is typically about 80 cm from the high- resolution digital camera, 18, and positioned above the high-resolution camera's field of view, so that it is not visible in the captured images. The white screen, 12, is a matte-finish (e.g., non-glare) white-colored screen which is illuminated to provide a constant and repeatable background against which the hair sample, 22, is measured. As the difference between bulk hair area and flyaway hair area is judged according to the brightness of the image (see below), it is important that the hair sample be photographed in front of a background which has a constant brightness. As seen in Fig. 1 , the preferred lighting equipment, 14, consists of twin photography lights located on each side of the sample, and pointing towards the white screen. Each of these lights is preferably a twin florescent tube light contained within a lighting fixture, and is typically from about 20 cm to about 60 cm to the side of the sample holder, 16. This places them far enough away from the hair sample, 22, so that they are not visible by the high-resolution digital camera, 18. This assures that the captured image will only include the image of the hair sample, 22, and will not include, for example, the back-side of the lighting equipment, 14. Therefore, the lighting equipment, 14, should not interfere with or block the picture to be taken. Also, in such a configuration, the hair sample, 22, is not directly illuminated by the lighting equipment, 14. Instead, light is first reflected from the white screen, 12, and then passes through the hair sample, 22, in order to reach the high-resolution digital camera, 18. The high-resolution digital camera, 18, is focused on the hair sample, 22, and not the white screen, 12. For ease of use, the high-resolution digital camera, 18, is connected to a personal computer, 20, and automatically transfers the captured image to the computer's imaging software. Such an arrangement provides a precise picture of the profile of the hair sample, 22, and avoids any glare and/or shadows which could interfere with measurement and analysis of the hair sample, 22. Preferably, the Image Analysis System should be located away from air currents or other forces which would disturb the hair sample, and is in a controlled temperature and humidity environment, so as to ensure repeatable results. The high-resolution digital camera (e.g., Model HC-2500 3-CCD from Fujifilm Co., of Tokyo, Japan) has a resolution of at least 1280 horizontal pixels, and 1000 vertical pixels. The high-resolution digital camera is calibrated to a linear gain, so that the incremental difference between all brightness values (an 8-bit, 0-255 brightness scale) is equal. Such a calibration may be achieved via, for example, utilizing a standard gray-scale calibration cell and/or the high- resolution digital camera's internal look-up-table (LUT). For calibration purposes, the white screen (when lit with the lighting equipment) should have a brightness value of greater than about 245, preferably from about 250 to about 255. The typical hair sample consists of 15 cm (5 g) straight black Asian hair switches (available from Kawamuraya Co., Osaka, Japan) or straight brown Caucasian hair switches (available from International Hair Importers & products Inc., Bellerose, New York, U.S.A.). Straight black Asian hair switches are preferred, because their contrast against the white screen is more easily observable. The measurements using the Image Analysis Protocol are significantly easier and more reproducible when black hair switches are used. However, the hair area reduction benefits, and the corresponding hair volume reduction benefits, of the present invention are applicable to all types of hair switches. Further, it has been shown that the results achieved with hair switches are comparable to the results achieved during actual use on people. The hair sample is prepared as follows: 1 ) Wet hair sample with warm water (38°C) for 30 seconds. 2) Apply 1 ml of ammonium iauryl sulfate solution to the hair sample and lather for 30 seconds. 3) Rinse the hair sample for 60 seconds. 4) Soak the hair sample in warm water for 24 hours. 5) Apply 1 ml of ammonium Iauryl sulfate solution to the hair sample and lather for 30 seconds. 6) Rinse the hair sample for 30 seconds. 7) Apply 1 ml of ammonium Iauryl sulfate solution to the hair sample and lather for 30 seconds. 8) Rinse the hair sample for 60 seconds. 9) For a treated hair sample: apply 1 ml of a hair care composition to be tested to the hair sample. 10) For a treated hair sample: rinse off the hair sample for 10 seconds. 11 ) Comb through the front of the hair sample 5 times. 12) Comb through the back of the hair sample 5 times. 13) Squeeze off excess water from the hair sample and make the cross-section round. 14) Leave the hair sample in a 21 °C / 65% relative humidity room and dry for 24 hours. 15) The hair sample is then ready to be measured by the Image Analysis System. Steps 9 and 10 are only performed for the treated hair samples. To compare the effect of a hair care composition on the bulk hair area, flyaway hair area, and total hair area, an "untreated picture" is first taken of a hair sample, and then a "treated picture" is taken. The untreated and treated bulk hair areas, flyaway hair areas, and total hair areas shown in the pictures, are then compared. Typically, the same hair switch is first used for the untreated hair sample, and then used for the treated hair sample, according to the procedure described above. Using the same hair switch minimizes sample-to-sample variations. Once a hair sample (either treated, or untreated), 22, is prepared, it is placed on the sample holder, 16, in front of the white screen, 12. The distance from the high-resolution digital camera, 18, and the hair sample, 22, should be the same for both the untreated and treated pictures. For both the untreated and treated pictures, the hair sample is aligned so that the widest profile (according to the bottom end of the hair sample) is captured by the high-resolution digital camera. This alignment approximates the way hair is arranged on the head, and therefore provides the most accurate view of the effect on hair area (and therefore hair volume), after treatment. This also assures an accurate measurement of the bulk hair area reduction, flyaway hair area reduction, and/or total hair area reduction effects. Once the hair is essentially motionless, an 8-bit, gray-scale picture is taken with the high-resolution digital camera, 18. Typically, the high-resolution digital camera, 18, assigns each pixel a brightness value of from 0 (pure black) to 255 (pure white). The picture is then transferred to the personal computer, 20. Alternatively, but less preferably, the personal computer may assign each pixel a brightness value from 0 to 255. Such a picture is also referred to as a "captured image," and may be saved electronically as, for example, a TIFF (Tagged Image File Format) file, for future reference. In the captured image, each hair sample appears as gray-to-black on a white background. The imaging software (e.g., Optimas v. 6.2, available from Media Cybernetics of Silver Springs, Maryland, U.S.A.) then analyzes the captured image, pixel-by-pixel. The imaging software uses the brightness value assigned to each pixel by the camera to classify each pixel as either black (brightness value = 0 - 120), gray (brightness value = 121 - 235), or white (brightness value = 236 - 255). The imaging software then defines"bulk hair" in the captured image as the largest continuous region bounded by black lines. The "flyaway hair" is defined as black, gray, and white regions bounded by one or more gray lines, excluding the bulk hair. The term "bounded" as used herein with respect to the imaging software indicates that the referred-to-area is completely surrounded by at least one line of the specified shade. The imaging software then calculates the area of each region, typically in cm 2 , to find the bulk hair area and the flyaway hair area. The total hair area is the sum of the bulk hair area and the flyaway hair area. Thus, the bulk hair area and/or the flyaway hair area may also be calculated as a percentage of the total hair area. In a preferred embodiment, the imaging software automatically sets the untreated total hair area equal to a value of 1.0, and normalizes the other values, accordingly. The imaging software may also outline and/or color code the bulk hair area and/or flyaway hair area for easy reference. The reduction in hair volume after treatment is based on comparing the data obtained from analyzing the treated and untreated hair samples. The hair areas are calculated for the untreated total hair area (UTA), the untreated bulk hair area (UBA), and the untreated flyaway hair area (UFA). These are then compared to the calculated hair areas for the treated total hair area (TTA), the treated bulk hair area (TBA), and the treated flyaway hair area (TFA). The reduction in bulk hair area after treatment corresponds to a reduction in the bulk hair volume, and is calculated according to the following equation: bulk hair area reduction = 100 * [1 - (TBA/UBA)]. Similarly, the percent reduction in flyaway hair area after treatment corresponds to a reduction in the flyaway hair volume, and is calculated according to the following equation: flyaway hair area reduction = 100 * [1 - (TFA/UFA)]. The percent reduction in total hair area after treatment corresponds to a reduction in the total hair volume, and calculated according to the following equation: total hair area reduction = 100 * [1 - (TTA/UTA)]. A given hair care composition (or control) is typically tested on at least three separate hair samples. The bulk hair area reduction, flyaway hair area reduction, and total hair area reduction are then calculated for each hair sample, and an average bulk hair area reduction, average flyaway hair area reduction, and average total hair area reduction are calculated. In a preferred embodiment of the Image Analysis Protocol, two pictures of each treated and untreated hair sample are taken. The first picture corresponds to the widest profile of the hair sample, while the second picture corresponds to the most narrow profile of the hair sample, which is typically a 90° rotation from the widest profile. Then, average values are calculated for the untreated bulk hair area, treated bulk hair area, etc. These average values are then employed in the above equations. Such a procedure is especially useful with hair samples which are slightly curved, due to their natural contours, or because of washing. EXAMPLES The following examples further describe and demonstrate the preferred embodiments within the scope of the present invention. The examples are given solely for the purpose of illustration and are not to be construed as limitations of the present invention since many variations thereof are possible without departing from the spirit and scope of the invention. Ingredients are identified by chemical name, or otherwise defined below. EXAMPLE 1 A hair conditioning composition is formed by the following process. The suitable carrier is an aqueous gel matrix, which is formed as follows: 81% deionized water is heated to 85°C, and 1% PEG-5 cocamine available from Th. Goldschmidt AG, 2% Stearamidopropyldimethylamine available from Nikko Chemical, and 1.4% L-glutamic acid from Ajinomoto are mixed with 3.6% cetyl alcohl and 6.4% stearyl alcohol from Shin-nihon Rika. The aqueous carrier is maintained at a temperature of about 85°C for about 5 minutes, until the components are homogenized, and no solids are observed. The aqueous carrier is then cooled to about 55°C and maintained at this temperature, until a gel matrix forms. Ester oils such as pentaerythrityl tetraisostearate available from Koukyu Alcohol Kogyo Co. are also added to the gel matrix. 2% PPG-34 (MW=2,000) available from Sanyo Kasei is mixed with the gel matrix with constant stirring and milling for 15 minutes, to assure homogenization. Silicones or silicone emulsions such as emulsion of gum and 20cs fluid blend under the trade name BY22-072 (Dow Corning) can be also added at this stage. The gel matrix is maintained at about 50°C during this time. After it is homogenized, it is allowed to cool to room temperature, packaged, and stored. A perfume and a preservative are also added to the hair care composition.
