Definitions

  • the present invention relates to a hair care composition comprising optical bhghteners which alter the color of the hair, while enhancing the shininess of the hair, and protecting the hair from further damage. More specifically, the present invention relates to a hair care composition comprising optical brighteners and non-volatile solvents.
  • the desire to regain the natural color and shine of damaged hair and the desire to alter the color of the hair to be more appealing are widely held. Damaged hair is perceived by the consumer as unfavorable appearances and less manageability of the hair. Such unfavorable appearances include alteration and fading of original color, less shine, and less luster.
  • a common way for alleviating the unfavorable appearances of damaged hair and to achieve appealing hair color is to dye the hair to the color desired. Dyeing the hair would provide the consumer with a stable color of hair for a relatively long period. However, dyeing the hair is generally time-consuming, cumbersome, and messy. Dyestuff may also be chemically harsh to the hair, scalp, and skin. The hair can be further damaged by dyeing. Thus, hair dye products are not suitable for daily use. Further, dyeing can leave the hair with a dull appearance, making the hair look less shiny.

Description

HAIR CARE COMPOSITIONS COMPRISING OPTICAL BRIGHTENERS AND NON-VOLATILE SOLVENTS
TECHNICAL FIELD The present invention relates to a hair care composition comprising optical bhghteners which alter the color of the hair, while enhancing the shininess of the hair, and protecting the hair from further damage. More specifically, the present invention relates to a hair care composition comprising optical brighteners and non-volatile solvents. BACKGROUND
The desire to regain the natural color and shine of damaged hair and the desire to alter the color of the hair to be more appealing are widely held. Damaged hair is perceived by the consumer as unfavorable appearances and less manageability of the hair. Such unfavorable appearances include alteration and fading of original color, less shine, and less luster.
A common way for alleviating the unfavorable appearances of damaged hair and to achieve appealing hair color is to dye the hair to the color desired. Dyeing the hair would provide the consumer with a stable color of hair for a relatively long period. However, dyeing the hair is generally time-consuming, cumbersome, and messy. Dyestuff may also be chemically harsh to the hair, scalp, and skin. The hair can be further damaged by dyeing. Thus, hair dye products are not suitable for daily use. Further, dyeing can leave the hair with a dull appearance, making the hair look less shiny.
Based on the foregoing, there is a need for a hair composition which can be used daily and which can alter the color of the hair, while enhancing the shininess of the hair, and protecting the hair from further damage.
Use of optical brighteners, or compounds otherwise described by names such as fluorescent whitening agents, fluorescent brighteners, or fluorescent dyes, in the hair care field has been known in the art, such as in United States Patent 3,658,985, United States Patent 4,312,855, Canadian Patent 1,255,603, United States Patent 3,577,528, Great Britain Patent Specification 1 ,328, 108, South African Application 676,049, European Publication 87,060, and Great Britain Patent Specification 2,307,639.
However, the addition of large amounts of optical brighteners to hair compositions can actually lessen the hair's shininess if the amount of optical brightener is such that it crystallizes after the aqueous components of the composition have evaporated or the hair has dried. Such crystallization can make the hair look dull or "dusty". Accordingly, there is a need for a hair care composition comprising optical brighteners in which a high deposition of the optical brightener on the hair is attainable, and yet in which a dulling or dusting of the hair's shininess is avoided.
None of the existing art provides all of the advantages and benefits of the present invention.
SUMMARY
The present invention is directed to a hair care composition comprising:
(a) an effective amount of an optical brightener; and (b) a non-volatile solvent for solubilizing at least 0.01 wt% of the optical brightener; wherein the optical brightener is deposited on the hair without crystallizing. These and other features, aspects, and advantages of the present invention will become evident to those skilled in the art from a reading of the present disclosure.

Suitable imidazoles include those with tradename of Cl. Fluorescence Brightener 352, or Uvtex AT available from Ciba Speciality Chemical. NON-VOLATILE SOLVENTS
The non-volatile solvents solubilize the optical brightener. As used herein,
465 "non-volatile" means having a boiling point greater than about 100°C Preferably the non-volative solvent is capable of dissolving at least 0.01 wt% of the optical brightener.
Optical brighteners in a water or ethanol solution, without a non-volatile solvent, can make the hair look dull or dusty after the water or ethanol has
470 evaporated, i.e., after the hair has dried. This dullness or dustiness results from crystallization of the optical brightener on the hair. If a non-volatile solvent is not added to the composition, the level of optical brightener in the composition must be reduced in order to prevent crystallization and the consequent dulling or dusting of the hair. This, however, is undesirable, because reduction in the level 475 of optical brightener causes a reduction in the benefits (e.g., color enhancement, shine, UV protection) provided by the optical brightener.
Without being bound by theory, it is believed that the addition of a nonvolatile solvent as described herein reduces the crystallization effect, and thus permits a high level of the optical brightener to be added to the hair care
480 composition, and thus deposited on the hair, but without compromising the benefits provided by the optical brightener.
Non-volatile solvents useful herein include alkyl alcohols having more than 3 carbons, and polyhydric alcohols. The polyhydric alcohols useful herein include 1 ,2-propane diol or propylene glycol, 1 ,3-propane diol, hexylene glycol, 485 glycerin, diethylene glycol, dipropylene glycol, 1 ,2-butylene glycol, and 1 ,4- butylene glycol. Preferably the hair care compositions of the present invention contain at least about 0.1 wt% of the non-volatile solvent. CARRIER
The hair care compositions of the present invention may comprise a 490 carrier. The level and species of the carrier are selected according to the compatibility with other components, and desired characteristic of the product.
The carrier useful in the present invention include volatile solvents, propellants, and mixtures thereof.

495 from 1 to 3 carbons, and hydrocarbons having from about 5 to about 8 carbons.
The preferred volatile solvents are water, ethanol, isopropanol, pentane, hexane, and heptane. The water useful herein include deionized water and water from natural sources containing mineral cations. Deionized water is preferred.
Propellants may be used for mousse and hair spray product forms. 500 Propellants, when used in the present invention, are selected depending on variables such as the remainder of components, the package, and whether the product is designed to be used standing or invert.
Propellants useful herein include fluorohydrocarbons such as difluoroethane 152a (supplied by DuPont), dimethylether, and hydrocarbons such
505 as propane, isobutane, n-butane, mixtures of hydrocarbons such as LPG
(liquefied petroleum gas), carbon dioxide, nitrous oxide, nitrogen, and compressed air. COMPOSITIONS

5io component which characterizes the form of the product. Product forms useful herein include, but are not limited to, shampoo, conditioner, treatment, mousse, spray, lotion, gel, and cream products, all of which can be designed for rinse-off or leave-on convenience. Product functions useful herein include, but are not limited to, cleansing, and conditioning products. For example, a detersive
515 surfactant, a hair conditioning agent, and mixtures thereof may be comprised. The components and their levels are selected by one skilled in the art depending on the desired characteristic of the product. DETERSIVE SURFACTANT
Compositions herein may include a detersive surfactant. The detersive
520 surfactants herein are those suitable for cleansing the hair. Detersive surfactants useful herein include anionic surfactants, amphoteric and zwitterionic surfactants, and nonionic surfactants.
The detersive surfactants, when present, are preferably included at a level of from about 0.01% to about 75% by weight of the composition. Two or more
525 surfactants can be used. Anionic Surfactant
Anionic surfactants useful herein include alkyl and alkyl ether sulfates. These materials have the respective formulae ROSOgM and RO(C2H40)χS03M, wherein R is alkyl or alkenyl of from about 8 to about 30
530 carbon atoms, x is 1 to about 10, and M is hydrogen or a cation such as ammonium, alkanolammonium (e.g., triethanolammonium), a monovalent metal cation (e.g., sodium and potassium), or a polyvalent metal cation (e.g., magnesium and calcium). Preferably, M should be chosen such that the anionic surfactant component is water soluble. The anionic surfactant or surfactants
535 should be chosen such that the Krafft temperature is about 15°C or less, preferably about 10°C or less, and more preferably about 0°C or less. It is also preferred that the anionic surfactant be soluble in the composition hereof.
Krafft temperature refers to the point at which solubility of an ionic surfactant becomes determined by crystal lattice energy and heat of hydration,
540 and corresponds to a point at which solubility undergoes a sharp, discontinuous increase with increasing temperature. Each type of surfactant will have its own characteristic Krafft temperature. Krafft temperature for ionic surfactants is, in general, well known and understood in the art. See, for example, Myers, Drew, Surfactant Science and Technology, pp. 82-85, VCH Publishers, Inc.

615 Other anionic surfactants for use herein include polyhydrophilic anionic surfactants. By "polyhydrophilic" herein, is meant a surfactant that has at least two hydrophilic groups which provide a hydrophilic nature. Polyhydrophilic surfactants useful herein are only those having at least two hydrophilic groups in the molecule, and is not intended to encompass those which only have one
620 hydrophilic group. One molecule of the polyhydrophilic anionic surfactant herein may comprise the same hydrophilic groups, or different hydrophilic groups. Specifically, the polyhydrophilic anionic surfactants comprise at least one group selected from the group consisting of carboxy, hydroxy, sulfate, sulfonate, and phosphate. Suitable polyhydrophilic anionic surfactants are those which
625 comprise at least one of a carboxy, sulfate, or sulfonate group, more preferably those which comprise at least one carboxy group.
Nonlimiting examples of polyhydrophilic anionic surfactants include N-acyl- L-glutamates such as N-cocoyl-L-glutamate and, N-lauroyl-L-glutamate, laurimino diproprionate, N-acyl-L-aspartate, di-(N-lauroyl N-methyl taurate),

C=0
R
645 wherein R is an alkyl of 8 to 18 carbons. Other polyhydrophilic anionic surfactants include olefin sulfonates having about 10 to about 24 carbon atoms. The term "olefin sulfonates" is used herein to mean compounds which can be produced by the sulfonation of alpha-olefins by means of uncomplexed sulfur trioxide, followed by neutralization of the acid reaction mixture in conditions such
650 that any sulfones which have been formed in the reaction are hydrolyzed to give the corresponding hydroxy-alkanesulfonates. The sulfur trioxide can be liquid or gaseous, and is usually, but not necessarily, diluted by inert diluents, for example by liquid SO2, chlorinated hydrocarbons, etc., when used in the liquid form, or by air, nitrogen, gaseous SO2, etc., when used in the gaseous form. The α-olefins
655 from which the olefin sulfonates are derived are mono-olefins having about 8 to about 24 carbon atoms, preferably about 10 to about 16 carbon atoms. Preferably, they are straight chain olefins. In addition to the true alkene sulfonates and a proportion of hydroxy-alkanesulfonates, the olefin sulfonates can contain minor amounts of other materials, such as alkene disulfonates
660 depending upon the reaction conditions, proportion of reactants, the nature of the starting olefins and impurities in the olefin stock and side reactions during the sulfonation process. A specific α-olefin sulfonate mixture of the above type is described more fully in U.S. Patent 3,332,880, to Pflaumer and Kessler, issued July 25, 1967, which is incorporated by reference herein in its entirety.
665 Another class of polyhydrophilic anionic surfactants are amino acid surfactants which are surfactants that have the basic chemical structure of an amino acid compound, i.e., that contains a structural component of one of the naturally-occurring amino acids. It is understood by the artisan that some surfactants may be regarded as both a polyhydrophilic anionic surfactant, and an
670 amino acid surfactant. These surfactants are suitable anionic surfactants.
Nonlimiting examples of amino acid surfactants include, N- cocoylalaninate, N-acyl-N-methyl-β-alanate, N-acylsarcosinate; N-alkylamino propionates and N-alkyliminodipropionates, specific examples of which include N-lauryl-β-amino propionic acid or salts thereof, and N-lauryl-β-imino- dipropionate, N-acyl-DL-alaninate, sodium lauryl sarcosinate, sodium lauroyl sarcosinate, lauryl sarcosine, cocoyl sarcosine, N-acyl-N-methyl taurate, lauroyl taurate, and lauroyl lactylate.
Commercially available anionic surfactants suitable are N-acyl-L- glutamate with a tradename AMISOFT CT-12S, N-acyl potassiumglycine with a tradename AMILITE GCK-12, lauroyl glutamate with a tradename AMISOFT LS- 1 1 , and N-acyl-DL-alaninate with tradename AMILITE ACT12 supplied by Ajinomoto; acylaspartate with tradenames ASPARACK and AAS supplied by Mitsubishi Chemical; and acyl derivaties of tradename ED3A supplied by Hampshire Chemical Corp. Optionally the counter ion of anionic surfactants may be polyvalent cations. It has been found that these anionic surfactants, along with the cationic conditioning agents, and polyvalent metal cations as described later, form a coacervate in the compositions. Cationic conditioning agents may be included in the present composition to provide a shampoo which both cleanse and condition the hair from a single product.
Coacervate formulation is dependent upon a variety of criteria such as molecular weight, component concentration, and ratio of interacting ionic components ionic strength, charge density of the cationic and anionic components, pH, and temperature. Coacervate systems and the effect of these parameters are known in the art.
It is believed to be particularly advantageous, for the anionic surfactants and the polyvalent metal cations at certain levels to be present with the cationic conditioning agents in a coacervate phase. The coacervates formed in the compositions are believed to readily deposit on the hair upon diluting the coacervate with abundant water, i.e., rinsing of the shampoo.
Without being bound by theory, it is believed that the coacervates provide two major effects to the present shampoo composition. First, it reduces the Critical Micelle Concentration (hereinafter "CMC") of the composition. The reduction of the CMC relates to reduction of the surface tension, thereby improving lather performance. Second, the existence of the anionic surfactants along with the polyvalent metal cations expand the coacervate region in the composition. As the cationic conditioning agents in the composition are mainly delivered to the hair via these coacervates, expansion of the coacervate region results in delivery of more cationic conditioning agents to the hair. Consequently, 710 compositions which both cleanse and condition the hair from a single product, which have improved overall conditioning benefits and improved lathering are provided.
Techniques of analysis of formation of complex coacervates are known in the art. For example, microscopic analysis of the shampoo compositions, at any
715 chosen stage of dilution, can be utilized to identify whether a coacervate phase has formed. Such coacervate phase will be identifiable as an additional emulsified phase in the composition. The use of dyes can aid in distinguishing the coacervate phase from other insoluble phases dispersed in the shampoo composition.

The compositions may comprise a high melting point compound having a melting point of at least about 25°C selected from the group consisting of fatty
1045 alcohols, fatty acids, fatty alcohol derivatives, fatty acid derivatives, hydrocarbons, steroids, and mixtures thereof. Without being bound by theory, it is believed that these high melting point compounds cover the hair surface and reduce friction, thereby resulting in providing smooth feel on the hair and ease of combing. It is understood by the artisan that the compounds disclosed in this
1050 section of the specification can in some instances fall into more than one classification, e.g., some fatty alcohol derivatives can also be classified as fatty acid derivatives.

1200 As used herein, the term "polymer" shall include 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. By "water soluble" cationic polymer, what is meant is a polymer which is sufficiently
1205 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 polymer will be sufficiently soluble to form a substantially clear solution at 0.5% concentration, more preferably at 1.0% concentration.
The cationic polymers hereof will generally have a weight average i2io molecular weight which is at least about 5,000, typically at least about 10,000, and is less than about 10 million. Preferably, the molecular weight is from about 100,000 to about 2 million. The cationic polymers will generally have cationic nitrogen-containing moieties such as quaternary ammonium or cationic amino moieties, and mixtures thereof.
1215 The cationic charge density is preferably at least about 0.1 meq/gram, more preferably at least about 1.5 meq/gram, even more preferably at least about 1.1 meq/gram, still more preferably at least about 1.2 meq/gram. Cationic charge density of the cationic polymer can be determined according to the Kjeldahl Method. Those skilled in the art will recognize that the charge density of
1220 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 counterions can be utilized for the cationic polymers so long as the water solubility criteria is met. Suitable counterions include halides (e.g.,
1225 Cl, Br, I, or F, preferably Cl, Br, or I), sulfate, and methylsulfate. Others can also be used, as this list is not exclusive.
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 can comprise copolymers,
1230 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 can be found in the CTFA Cosmetic Ingredient Dictionary, 3rd edition, edited by Estrin, Crosley, and Haynes, (The Cosmetic, Toiletry, and Fragrance Association, Inc.,

Amine-substituted vinyl monomers can be polymerized in the amine form, and then optionally can be converted to ammonium by a quaternization reaction.
1250 Amines can also be similarly quaternized subsequent to formation of the polymer. For example, tertiary amine functionalities can be quaternized by reaction with a salt of the formula R'X wherein R' is a short chain alkyl, preferably a C-| - C7 alkyl, more preferably a C-| - C3 alkyl, and X is an anion which forms a water soluble salt with the quaternized ammonium.

These silicone compounds are available, for example, from the General Electric Company in their ViscasilR and SF 96 series, and from Dow Corning in their Dow Corning 200 series.
1360 Polyalkylaryl siloxane fluids can also be used and include, for example, polymethylphenylsiloxanes. These siloxanes are available, for example, from the General Electric Company as SF 1075 methyl phenyl fluid or from Dow Corning as 556 Cosmetic Grade Fluid.
Especially preferred, for enhancing the shine characteristics of hair, are
1365 highly arylated silicone compounds, such as highly phenylated polyethyl silicone having refractive index of about 1.46 or higher, especially about 1.52 or higher. When these high refractive index silicone compounds are used, they should be mixed with a spreading agent, such as a surfactant or a silicone resin, as described below to decrease the surface tension and enhance the film forming
1370 ability of the material.
The silicone compounds that can be used include, for example, a polypropylene oxide modified polydimethylsiioxane although ethylene oxide or mixtures of ethylene oxide and propylene oxide can also be used. The ethylene oxide and polypropylene oxide level should be sufficiently low so as not to

1450 References disclosing suitable nonvolatile dispersed silicone compounds include U.S. Patent No. 2,826,551 , to Geen; U.S. Patent No. 3,964,500, to Drakoff, issued June 22, 1976; U.S. Patent No. 4,364,837, to Pader; and British Patent No. 849,433, to Woolston, all of which are incorporated herein by reference in their entirety. Also incorporated herein by reference in its entirety is
1455 "Silicon Compounds" distributed by Petrarch Systems, Inc., 1984. This reference provides an extensive, though not exclusive, listing of suitable silicone compounds.
Another nonvolatile dispersed silicone that can be especially useful is a silicone gum. The term "silicone gum", as used herein, means a
1460 polyorganosiloxane material having a viscosity at 25°C of greater than or equal to 1 ,000,000 centistokes. It is recognized that the silicone gums described herein can also have some overlap with the above-disclosed silicone compounds. This overlap is not intended as a limitation on any of these materials. Silicone gums are described by Petrarch, and others including U.S. Patent No. 4,152,416, to
1465 Spitzer et al., issued May 1 , 1979 and Noll, Walter, Chemistry and Technology of Silicones, New York: Academic Press 1968. Also describing silicone gums are General Electric Silicone Rubber Product Data Sheets SE 30, SE 33, SE 54 and SE 76. All of these described references are incorporated herein by reference in their entirety. The "silicone gums" will typically have a mass molecular weight in
1470 excess of about 200,000, generally between about 200,000 and about 1 ,000,000. Specific examples include polydimethylsiioxane, poϊy(dimethylsiloxane methylvinylsiloxane) copolymer, polydimethylsiioxane diphenylsiloxane methylvinylsiloxane) copolymer and mixtures thereof.
Also useful are silicone resins, which are highly crosslinked polymeric
1475 siloxane systems. The crosslinking is introduced through the incorporation of tri- functional and tetra-functional silanes with mono-functional or di-functional, or both, silanes during manufacture of the silicone resin. 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
1480 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
1485 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
1490 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
1495 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
1500 material given the CTFA designation poiymethylsilsequioxane, 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, which is incorporated herein by
1505 reference in its entirety.
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 i5io make up the silicone. Briefly, the symbol M denotes the mono-functional unit (CH3)3SiO) 5; D denotes the difunctional unit (CH3)2SiO; T denotes the trifunctional unit (CH3)SiO-| 5; and Q denotes the quadri- or tetra-functional unit Siθ2- 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
1515 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 molecular weight, complete the description of the silicone material under the MDTQ system.
1520 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,
1525 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 average molecular weight of the resin is from about 1000 to about 10,000. Nonionic Polymer
1530 Nonionic polymers useful herein include cellulose derivatives, hydrophobically modified cellulose derivatives, ethylene oxide polymers, and ethylene oxide/propylene oxide based polymers. Suitable nonionic polymers are cellulose derivatives including methylcellulose with tradename BENECEL, hydroxyethyl cellulose with tradename NATROSOL, hydroxypropyl cellulose with
1535 tradename KLUCEL, cetyl hydroxyethyl cellulose with tradename POLYSURF 67, all supplied by Herculus. Other suitable nonionic polymers are ethylene oxide and/or propylene oxide based polymers with tradenames CARBOWAX PEGs, POLYOX WASRs, and UCON FLUIDS, all supplied by Amerchol. Polyalkylene Glycols
1540 These compounds are particularly useful for compositions which are designed to impart a soft, moist feeling to the hair. When present, the polyalkylene glycol is typically used at a level from about 0.025% to about 1.5%, preferably from about 0.05% to about 1 %, and more preferably from about 0.1 % to about 0.5% of the compositions.
1545 The polyalkylene glycols are characterized by the general formula:
H ( OCH2 CH) n - OH
I R
1550 wherein R is selected from the group consisting of H, methyl, and mixtures thereof. When R is H, these materials are polymers of ethylene oxide, which are also known as polyethylene oxides, polyoxyethylenes, and polyethylene glycols. When R is methyl, these materials are polymers of propylene oxide, which are also known as polypropylene oxides, polyoxypropylenes, and polypropylene
1555 glycols. When R is methyl, it is also understood that various positional isomers of the resulting polymers can exist.
In the above structure, n has an average value of from about 1500 to about 25,000, preferably from about 2500 to about 20,000, and more preferably from about 3500 to about 15,000.
1560 Polyethylene glycol polymers useful herein are PEG-2M wherein R equals H and n has an average value of about 2,000 (PEG-2M is also known as Polyox WSR® N-10, which is available from Union Carbide and as PEG-2,000); PEG-5M wherein R equals H and n has an average value of about 5,000 (PEG-5M is also known as Polyox WSR® N-35 and Polyox WSR® N-80, both available from
1565 Union Carbide and as PEG-5,000 and Polyethylene Glycol 300,000); PEG-7M wherein R equals H and n has an average value of about 7,000 (PEG-7M is also known as Polyox WSR® N-750 available from Union Carbide); PEG-9M wherein R equals H and n has an average value of about 9,000 (PEG 9-M is also known as Polyox WSR® N-3333 available from Union Carbide); and PEG-14 M wherein
1570 R equals H and n has an average value of about 14,000 (PEG-14M is also known as Polyox WSR® N-3000 available from Union Carbide). Other useful polymers include the polypropylene glycols and mixed polyethylene/polypropylene glycols. ADDITIONAL COMPONENTS
1575 The compositions of the present invention may include a variety of additional components, which may be selected by the artisan according to the desired characteristics of the final product. Additional components include, for example, polyvalent metal cations, suspending agents, and other additional components.
1580 Polyvalent Metal Cations
Suitable polyvalent metal cations include divalent and trivalent metals, divalent metals being preferred. Exemplary metal cations include alkaline earth metals, such as magnesium, calcium, zinc, and copper, and trivalent metals such as aluminum and iron. Preferred are calcium and magnesium.
1585 The polyvalent metal cation can be added as an inorganic salt, organic salt, or as a hydroxide. The polyvalent metal cation may also be added as a salt with anionic surfactants as mentioned above.
Preferably, the polyvalent metal cation is introduced as an inorganic salt or organic salt. Inorganic salts include chloride, bromide, iodine, nitrate, or sulfate,
1590 more preferably chloride or sulfate. Organic salts include L-glutamate, lactate, malate, succinate, acetate, fumarate, L-glutamic acid hydrochloride, and tartarate.
It will be clear to those skilled in the art that, if polyvalent salts of the anionic surfactant is used as the mode of introducing the polyvalent metal cations
1595 into the compositions hereof, only a fraction of the anionic surfactant may be of polyvalent form, the remainder of the anionic surfactant being necessarily added in monovalent form.
Hardness of the conditioning shampoo compositions can be measured by standard methods in the art, such as by ethylene diamine tetraacetic acid (EDTA)
1600 titration. In the event that the composition contains dyes or other color materials that interfere with the ability of EDTA titration to yield a perceptible color change, hardness should be determined fro the composition in the absence of the interfering dye or color. Suspending Agents
1605 A preferred additional component is a suspending agent, particularly for compositions comprising silicone compounds of high viscosity and/or large particle size. When present, the suspending agent is in dispersed form in the compositions.

EXAMPLES
1670 The following examples further describe and demonstrate 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, as many variations thereof are possible without departing from the sprit and scope of the invention. Ingredients are identified by chemical or CTFA
1675 name, or otherwise defined below. Method of Preparation
The hair spray, mousses, lotions and conditioners are suitably made as follows: If included in the formula, polymeric materials are dispersed in water at room temperature. If required, the polymeric materials such as Carbomer and
1680 Acrylates/Steareth-20 Methacrylate Copolymer may be neutralized after dispersing. The mixture is then heated up to above 60°C, and fatty alcohols and emulsifiers are added if included in the formulation. After cooling down to below 50°C, the remaining components are added with agitation then cooled down to about 30°C Ethanol is added here if included in the formula. A triblender and mill
1685 can be used if necessary to disperse the materials. As appropriate, the mixture thus obtained can be packed into an aerosol can with propellant.
The shampoos are suitably prepared by any conventional method well known in the art. A suitable method is as follows: polymer and surfactants are dispersed in water to form a homogeous mixture. To this mixture are added the
1690 other ingredients except for silicone emulsion (if present), perfume, and salt; the obtained mixture is agitated. If present, the silicone emulsion is made with Dimethicone or Dimethiconol, a small amount of detersive surfactant, and a portion of water. The obtained mixture is then passed through a heat exchanger to cool, and the silicone emulsion, perfume, and salt are added. The obtained
1695 compositions are poured into bottles to make hair shampoo compositions.
Alternatively, water and surfactants and any other solids that need to be melted can be mixed together at elevated temperature, e.g., above about 70°C, to speed the mixing into shampoo. Additional ingredients can be added either to this hot premix or after cooling the premix. The ingredients are mixed thoroughly
1700 at the elevated temperature and then pumped through a high shear mill and then through a heat exchanger to cool them to ambient temperature. If present in the composition, silicone emulsified at room temperature in concentrated surfactant is added to the cooled mix.
