Description

HAIR CONDITIONING COMPOSITION COMPRISING

CARBOXYLIC ACID/CARBOXYLATE COPOLYMER AND

VINYLPYRROLIDONE COPOLYMER

TECHNICAL FIELD The present invention relates to hair conditioning compositions comprising an carboxylic acid/carboxylate copolymer and vinylpyrrolidone copolymer.

BACKGROUND

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 the hair in a wet, tangled, and generally unmanageable state. Once the hair dries, it 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 "fly-away hair", or contribute to an undesirable phenomena of "split ends", particularly for long hair.

A variety of approaches have been developed to alleviate these after- shampoo problems. These approaches range from post-shampoo application of hair conditioner such as leave-on and rinse-off products, to hair conditioning shampoos which attempt to both cleanse and condition the hair from a single product. Although some consumers prefer the ease and convenience of a shampoo which includes conditioners, a substantial proportion of consumers prefer the more conventional conditioner formulations which are applied to the hair as a separate step from shampooing, usually subsequent to shampooing. Such consumers who prefer the conventional conditioner formulations value the relatively higher conditioning effect, or convenience of changing the amount of conditioning depending on the condition of hair or portion of hair.

Conditioning formulations can be in the form of rinse-off products or leave- on products, and can be in the form of an emulsion, cream, gel, spray, and mousse. Products in the form of cream, gel, and mousse are suitable in that the consumer can easily control the amount and distribution of the product. As such, these products are particularly suitable for leave-on products.

A common method of providing conditioning benefit to the hair is through the use of hair conditioning agents such as cationic surfactants and polymers, silicone conditioning agents, hydrocarbon oils, and fatty alcohols. Cationic surfactants and polymers, hydrocarbon oils and fatty alcohols are known to enhance hair shine and provide moistness, softness, and static control to the hair. However, such components can also provide greasy or waxy feeling. Silicone conditioning agents are also known to provide conditioning benefits such as smoothness and combing ease due to the low surface tension of silicone compounds. However, silicone conditioning agents can cause dry feel or frizzy condition to the hair. Moreover, when these conditioning agents are included in a leave-on product, they may further leave the hands with a tacky, dirty, feeling.

Furthermore, most of these conditioning agents are also known to weigh down the hair, when these conditioning agents are included in a hair conditioning compositions. The weighed down hair gives an appearance of reduced bulk hair volume. For consumers who desire hair volume-up such as consumers having fine hair, the effect of hair weighing down is not desirable. The term "hair volume- up" as used herein is not equal to fly-away hair. Fly-away hair is due to the increased level of static, and represents volume increase of only very minor amount of the hair as a whole, and is not desirable. On the other hand, hair volume-up as used herein relates to increase of the bulk of the hair volume. Consumers having fine hair have the desire to achieve hair volume-up while controlling undesirable fly-away of the hair.

Based on the foregoing, there remains a desire to provide hair conditioning compositions suitable for leave-on use which provide improved conditioning benefits to the hair such as smoothness, softness, and reduction of friction, are easy to apply on the hair, and leave the hair and hands with a clean feeling.

It is also desirable to provide hair conditioning compositions which provide hair volume-up while not deteriorating conditioning benefits such as softness, moisturized feel, and fly-away control.

None of the existing art provides all of the advantages and benefits of the present invention.

CARBOXYLIC ACID/CARBOXYLATE COPOLYMER

The compositions of the present invention comprise a carboxylic acid/carboxylate copolymer. The carboxylic acid/carboxylate copolymers herein are hydrophobically-modified cross-linked coplymers of carboxylic acid and alkyl carboxylate, and have an amphiphilic property. These carboxylic acid/carboxylate copolymers are obtained by copolymerizing 1 ) a carboxylic acid monomer such as acrylic acid, methacrylic acid, maleic acid, maleic anhydride, itaconic acid, fumaric acid, crotonic acid, or α-chloroacrylic acid, 2) a carboxylic ester having an alkyl chain of from 1 to about 30 carbons, and preferably 3) a crosslinking agent of the following formula:

wherein R52 is a hydrogen or an alkyl group having from about 1 to about 30 carbons; γ1 , indepedently, is oxygen, CH2O, COO, OCO,

30. The carboxylic acid/carboxylate copolymers herein are believed to provide appropriate viscosity and rheology properties to the composition, and to emulsify and stabilize certain conditioning agents in the composition. It is further believed that, because of the alkyl group contained in the copolymer, the carboxylic acid/carboxylate copolymers do not make the composition undesirably sticky.

The composition of the present invention preferably comprises the carboxylic acid/carboxylate copolymer at a level by weight of from about 0.01 % to about 10%, more preferably from about 0.1 % to about 2%. The weight of the carboxylic acid/carboxylate copolymer is preferably greater than about 0.5 times, more preferably 1.0 times, the weight of the high melting point compound.

VINYLPYRROLIDONE COPOLYMER

The compositions of the present invention comprise a vinylpyrrolidone copolymer. The vinylpyrrolidone copolymers useful herein are those which comprise monomers other than vinylpyrrolidone. The vinylpyrrolidone copolymers useful herein are believed to provide increase in bulk hair volume while not deteriorating conditioning benefits such as fly-away control. Vinylpyrrolidone copolymers are typically included in the hair styling compositions as a film former or a hair fixative. It has been surprisingly found that when the copolymers are included in the hair conditioning compositions, together with carboxylic acid/carboxylate copolymer, increase in bulk hair volume is significantly improved.

Buffers and other pH adjusting agents can be included to achieve the desirable pH. SILICONE COMPOUND

Preferably, the compositions of the present invention contain a silicone compound. The silicone compounds useful herein include volatile soluble or insoluble, or nonvolatile soluble or insoluble silicone conditioning agents. By soluble what is meant is that the silicone compound is miscible with the carrier of the composition so as to form part of the same phase. By insoluble what is meant is that the silicone forms a separate, discontinuous phase from the carrier, such as in the form of an emulsion or a suspension of droplets of the silicone. The silicone compounds herein may be made by any suitable method known in the art, including emulsion polymerization. The silicone compounds may further be incorporated in the present composition in the form of an emulsion, wherein the emulsion is made my mechanical mixing, or in the stage of synthesis through emulsion polymerization, with or without the aid of a surfactant selected from anionic surfactants, nonionic surfactants, cationic surfactants, and mixtures thereof.

The silicone compounds herein are preferably used at levels by weight of the composition of from about 0.1 % to about 40%, more preferably from about 0.1% to about 10%, still more preferably from about 0.1 % to about 5%.

A nonvolatile dispersed silicone that can be especially useful is a silicone gum. The term "silicone gum", as used herein, means a 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 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. The "silicone gums" will typically have a mass molecular weight in excess of about 200,000, generally between about 200,000 and about 1 ,000,000. Specific examples include polydimethylsiloxane, poIy(dimethylsiloxane methylvinylsiloxane) copolymer, poly(dimethylsiloxane diphenylsiloxane methylvinylsiloxane) copolymer and mixtures thereof.

Also useful are silicone resins, which are highly crosslinked polymeric siloxane systems. The crosslinking is introduced through the incorporation of tri- functional and tetra-functional silanes with mono-functional or di-fu notional, 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 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:si!icon 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 (CH₃)₃SiO₀₅; D denotes the difunctional unit (CH₃)₂SiO; T denotes the trifunctional unit (CH₃)SiO., 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 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 average molecular weight of the resin is from about 1000 to about 10,000.

The silicone compounds herein also include polyalkyl or polyaryl siloxanes with the following structure (I)

wherein R⁹³ is alkyl or aryl, and x is an integer from about 7 to about 8,000. Z⁸ represents groups which block the ends of the silicone chains. The alkyl or aryl groups substituted on the siloxane chain (R⁹³) or at the ends of the siloxane chains Z⁸ can have any structure as long as the resulting silicone remains fluid at room temperature, is dispersible, is neither irritating, toxic nor otherwise harmful when applied to the hair, is compatible with the other components of the composition, is chemically stable under normal use and storage conditions, and is capable of being deposited on and conditions the hair. Suitable Z⁸ groups include hydroxy, methyl, methoxy, ethoxy, propoxy, and aryloxy. The two R⁹³ groups on the silicon atom may represent the same group or different groups. Preferably, the two R⁹³ groups represent the same group. Suitable R⁹³ groups include methyl, ethyl, propyl, phenyl, methylphenyl and phenylmethyl. The preferred silicone compounds are polydimethylsiloxane, polydiethylsiloxane, and polymethylphenylsiloxane. Polydimethylsiloxane, which is also known as dimethicone, is especially preferred. The polyalkylsiloxanes that can be used include, for example, polydimethylsiloxanes. These silicone compounds are available, for example, from the General Electric Company in their Viscasil® and SF 96 series, and from Dow Corning in their Dow Corning 200 series.

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 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 ability of the material.

The silicone compounds that can be used include, for example, a polypropylene oxide modified polydimethylsiloxane 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 interfere with the dispersibility characteristics of the silicone. These material are also known as dimethicone copolyols. Other silicone compounds include amino substituted materials. Suitable alkylamino substituted silicone compounds include those represented by the following structure (II)

wherein R⁹⁴ is H, CH₃ or OH, p¹, p², q¹ and q² are integers which depend on the molecular weight, the average molecular weight being approximately between 5,000 and 10,000. This polymer is also known as "amodimethicone".

Suitable amino substituted silicone fluids include those represented by the formula (III) (R⁹⁷)_aG₃. -Si-(OSiG₂)_P3-(OSiG_b(R⁹⁷)₂._b)_p4-O-SiG₃._a(R⁹⁷)_a (III) in which G is chosen from the group consisting of hydrogen, phenyl, OH, C.,-C₈ alkyl and preferably methyl; a denotes 0 or an integer from 1 to 3, and preferably equals 0; b denotes 0 or 1 and preferably equals 1 ; the sum p³+p⁴ is a number from 1 to 2,000 and preferably from 50 to 150, p³ being able to denote a number from 0 to 1 ,999 and preferably from 49 to 149 and p⁴ being able to denote an integer from 1 to 2,000 and preferably from 1 to 10; R⁹⁷ is a monovalent radical of formula C_q3H_2q3L in which q³ is an integer from 2 to 8 and L is chosen from the groups

— N(R⁹⁶)CH₂— CH₂— NR⁹⁶H₂X' in which R⁹⁶ is chosen from the group consisting of hydrogen, phenyl, benzyl, a saturated hydrocarbon radical, preferably an alkyl radical containing from 1 to 20 carbon atoms, and X' denotes a halide ion.

An especially preferred amino substituted silicone corresponding to formula (II) is the polymer known as "trimethylsilylamodimethicone" wherein R⁹⁴ is CH₃. Other amino substituted silicone polymers which can be used are represented by the formula (V):

where R⁹⁸ denotes a monovalent hydrocarbon radical having from 1 to 18 carbon atoms, preferably an alkyl or alkenyl radical such as methyl; R⁹⁹ denotes a hydrocarbon radical, preferably a C C₁₈ alkylene radical or a C C₁₈, and more preferably C|-C₈, alkyleneoxy radical; Q^" is a halide ion, preferably chloride; p⁵ denotes an average statistical value from 2 to 20, preferably from 2 to 8; p⁶ denotes an average statistical value from 20 to 200, and preferably from 20 to 50.

Cationic Polymers

Cationic polymers are useful herein. 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 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 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.

PRODUCT FORMS

The hair conditioning compositions of the present invention can be in the form of rinse-off products or leave-on products, can be transparent or opaque, and can be formulated in a wide variety of product forms, including but not limited to creams, gels, emulsions, mousses and sprays. Preferably, the compositions of the present invention may be leave-on products. The compositions of the present invention are preferably transparent, especially when leave-on products. What is meant by transparent, is that a black substance having the size of a 1cm X 1 cm square can be detected by the naked eye through 1cm thickness of the present composition. METHOD OF USE

The hair conditioning composition of the present invention are used in conventional ways to provide the conditioning and other benefits of the present invention. Such method of use depends upon the type of composition employed but generally involves providing hair, or a hair sample, having a bulk hair area, applying an effective amount of the product to the hair, and then drying the hair. Before drying, the hair conditioning composition may be either 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 conditioning benefits and desired increase in bulk hair volume. In general, from about 1 g to about 50 g is applied to the hair, and/or the scalp. The phrase "increase in bulk hair volume" as used herein is not equal to fly-away hair. Fly-away hair is due to the increased level of static, and represents volume increase of only very minor amount of the hair as a whole, and is not desirable. On the other hand, increase in bulk hair volume as used herein relates to the volume increase of the hair as a whole while controlling fly-away of the hair.

During the applying step, the hair care 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. For a leave-on form, the hair care composition is preferably applied to wet or damp hair prior to drying of the hair. After such hair care compositions are applied to the hair, the hair is dried and styled in accordance with the preference of the user. In the alternative, it may be applied to already dry hair, and the hair is then combed or styled, and dried in accordance with the preference of the user.
