Description

CONCENTRATED HAIR CONDITIONING COMPOSITION

FIELD OF THE INVENTION

The present invention relates to concentrated hair conditioning compositions comprising a silicone conditioning agent which deposits well on the hair and delivers hair conditioning benefit to the hair by dispersing the composition to the rinse water and rinsing the hair with such treated rinse water.

BACKGROUND

Human hair becomes soiled due to its contact with the surrounding environment and from the sebum secreted by the scalp. The soiling of hair causes it to have a dirty feel and an unattractive appearance. The soiling of the hair necessitates shampooing with frequent 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 hair 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 conditioners such as leave-on and rinse-off products, to hair conditioning shampoos which attempt to both clean 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. The conditioning formulations thus applied to the hair would then typically be rinsed off from the hair, and the hair would be left to dry.

In order to meet the needs of consumers living in locations where water supply is unstable and thereby desiring conditioning benefit to the hair without using water excess to the amount that would be used for shampooing the hair, a concentrated hair conditioning composition and its method of use was proposed in co-pending PCT application PCT/US00/24973. Such concentrated hair conditioning composition is used for conditioning the hair by: providing a treated water by dispersing the concentrated hair conditioning composition to water in, for example, a basin and/or scoop; and rinsing the hair with the treated water. In view of such method of use, good dispersing properties upon contact with water is desired for concentrated hair conditioning compositions. Yet, consumers do not wish to compromise on conditioning performance for good dispersing properties. A conditioning agent that has good deposition on the hair is desired for such method of use.

Based on the foregoing, there remains a desire to provide concentrated hair conditioning compositions which, when applied to the hair as treated water, provide good deposition on the hair, thereby providing hair conditioning benefits such as smooth feel when the hair is wet, combing ease when the hair is wet or dry, and softness when the hair is dry. There is also a desire to provide such hair conditioning compositions which disperse easily upon contact with water.

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

SUMMARY The present invention is directed to a concentrated hair conditioning composition for preparing a treated water having a silicone conditioning agent concentration of 0.001% to 2% for applying to the hair comprising:

(1) from about 0.01% to about 20% by weight of a silicone conditioning agent; and

(2) an aqueous carrier; wherein the composition is capable of providing a deposition of from about 10ppm to about 5000ppm of silicone conditioning agent when applied to the hair as the treated water.

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.

DETAILED DESCRIPTION While the specification concludes with claims which particularly point out and distinctly claim the invention, it is believed the present invention will be better understood from the following description.

All cited references 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. METHOD OF CONDITIONING AND PRODUCT FORM

The present invention is directed to a concentrated hair conditioning composition which is used by a method comprising the steps of: (a) providing a treated water by dispersing the conditioning composition to water, wherein the treated water has a concentration by weight of from 0.001 % to 2% of the silicone conditioning agent; and (b) rinsing the hair with the treated water.

In the method of the present invention, the concentrated hair conditioning composition is dispersed in water, and the treated water thus obtained is applied to the hair. The term "treated water" is defined under the Definitions Section above. This term as used herein describes water provided by the user and to which at least the conditioning composition is dispersed, and in addition, optionally other components such as rinse aid systems are dispersed in the same water. Such treated water is applied to dry or wet hair for providing conditioning benefit to the hair. The treated water can be made in a basin and/or scoop, or any other convenient vessel, typically a basin and/or scoop available in the user's home.

In one preferred embodiment, the concentrated hair conditioning composition is used by a method comprising the steps of:

(a) applying a shampoo composition comprising a detersive surfactant to the hair;

(b) providing a treated water by dispersing the conditioning composition to water, wherein the treated water has a concentration by weight of from 0.001% to 2% of the silicone conditioning agent; and

(c) rinsing the hair with the treated water.

Steps (a) and (b) can be reversed. In this embodiment, the treated water is applied to the hair after a shampoo composition comprising a detersive surfactant is applied and worked through the hair. Thus, rinsing the hair with treated water provides two functions at the same time, namely, it washes away the shampoo composition and soils from the hair while also providing conditioning benefit to the hair. This allows the user to provide conditioning benefits to the hair without using water excess to the amount that would be used for shampooing the hair. The shampoo composition to be used in step (a) can be any composition comprising detersive surfactants and is suitable for washing off soils from the hair. The term detersive surfactant, as used herein, is intended to distinguish these surfactants from surfactants which are primarily emulsifying surfactants, i.e. surfactants which provide an emulsifying benefit and which have low cleansing performance. It is recognized that most surfactants have both detersive and emulsifying properties. It is not intended to exclude emulsifying surfactants from the present invention, provided the surfactant also possesses sufficient detersive properties to be useful herein. Detersive surfactants are typically selected from the group consisting of anionic surfactants, amphoteric surfactants, nonionic surfactants, and mixtures thereof. In one preferred embodiment, at least an anionic surfactant is included in the shampoo composition to be used in step (a).

The present invention is also directed to a method of purifying water for applying to the hair comprising the step of adding a rinse aid system to the water. It has been surprisingly found that, when the pre-purified water contains a high amount of heavy metal ions and salts, the purified water obtained by the method herein can provide benefit to the hair when applied, such as soft feel to the hair, even without any hair conditioning agents, as compared to the pre-purified water. The rinse aid system for purifying water is preferably included in the concentrated hair conditioning composition. For providing a conditioning benefit to the hair while not negatively affecting the rinsing ability of the shampoo composition and soils from the hair, the treated water has a concentration by weight of from 0.001 % to 2%, preferably from about 0.001 % to about 0.5% of silicone conditioning agent. In order for the user to achieve this suitable concentration of treated water, the conditioning composition of the present invention may be provided in a package means containing a unit dose of the conditioning composition, or with a measuring means. The dosage of the composition is determined based on the amount of water contained in an average size vessel provided by the user, for example a basin and/or scoop, for making the treated water. The conditioning composition of the present invention can be provided in any form which is suitable for transportation and storage at ambient temperatures, and is readily applicable to the water upon use to make the treated water. As the conditioning composition is designed to readily disperse in water, the composition is typically easily degraded by humidity. Packaging for any product form is selected to avoid humidity and preferably, accidental contact with water.

The conditioning composition of the present invention is in the form of a liquid such as a gel or paste, the carrier being aqueous. Suitable packaging for such product form include sachets, or constructed packaging having one or more compartments.

SILICONE CONDITIONING AGENT

The present composition comprises from about 0.01% to about 20%, preferably from about 0.5% to about 5% of a silicone conditioning agent. The silicone conditioning agents useful herein include those which are capable of providing a deposition of from about 10ppm to about 5000ppm, preferably from about 20ppm to about 500ppm, when applied to the hair as the treated water. The term "deposition" is defined in the Definitions Section above. Of notice is that the deposition measurement is conducted using the treated water having a measured concentration of the silicone conditioning agent, wherein such concentration is controlled to be between 0.001% to 2%. The conditioning composition for making such treated water may contain additional conditioning agents and other components. Such additional conditioning agents and other components may or may not affect the deposition of the silicone conditioning agents. The level and species of the silicone conditioning agent is selected so that the given deposition is achieved, in consideration of the influence of such additional conditioning agents and other components. Without being bound by theory, it is believed that, by having a controlled level of deposition on the hair, hair conditioning benefits such as smooth feel when the hair is wet, combing ease when the hair is wet or dry, and softness when the hair is dry can be provided, while still providing good dispersability upon making the treated water. Preferred are silicone conditioning agents which are also dispersible upon making the treated water. The term "dispersible" is defined in the Definitions Section above.

The silicone conditioning agents useful herein include hydrophilically substituted silicone conditioning agents. The silicone conditioning agents for use herein will preferably have a viscosity of less than about 5,000 mPa*s at 25 °C, more preferably less than about 1 ,000 mPa *s at 25°C. The viscosity can be measured by means of a glass capillary viscometer as set forth in Dow Corning Corporate Test Method CTM0004, July 20, 1970. Other nonvolatile silicone conditioning agents having hair conditioning properties can also be used. Without being bound by theory, silicone conditioning agents having lower viscosities are believed to provide faster dispersion when in contact with water. Silicone conditioning agents having no hydrophilic functionality and/or viscosities of over 5,000 mPa ^«s at 25 °C can be used, although are preferably kept to a small amount, as they tend to make the composition less dispersible.

Particularly preferred silicone conditioning agents herein are those having substitute groups selected from the group consisting of alkoxy groups, amino groups, quaternary amino groups, and mixtures thereof. Silicone conditioning agents having alkoxy groups such as ethylene oxide groups are preferred as they are easily dispersed in water, and provide good transparency to the treated water. Silicone conditioning agents having amino groups and/or quaternary amino groups are preferred as they have good solubility, and also provide good conditioning performance as being substantive to the hair surface.

In one embodiment, the silicone conditioning agents provide a transparent conditioning composition, as well as a transparent treated water. The term "transparent" is defined in the Definitions Section above.

The hydrophilically substituted silicone conditioning agents that can be used include, for example, a polyethylene oxide modified polydimethylsiloxane although mixtures of ethylene oxide and propylene oxide can also be used. The polypropylene oxide level should be sufficiently low so as not to interfere with the dispersability characteristics of the silicone. . These materials are also known as dimethicone copolyols. These materials can be directly dispersed in water. Other hydrophilically substituted silicone conditioning agents include amino substituted materials. Suitable alkylamino substituted silicone conditioning agents include those represented by the following structure (II)

Silicone conditioning agents herein also include polyalkyl or polyaryl siloxanes with the following structure (I)

wherein R¹²³ 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 (R¹²³) 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 R¹²³ groups on the silicon atom may represent the same group or different groups. Preferably, the two R¹²³ groups represent the same group. Suitable R¹²³ 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 (Waterford, New York, USA) in their Viscasil® and SF 96 series, and from Dow Corning Corp. (Midland, Michigan, USA) in their Dow Corning 200 series and BY22-067.

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. Highly arylated silicone compounds can be used for enhancing the shine characteristics of hair, are 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.

Other silicone conditioning agents that can be 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 a/., issued May 1 , 1979 and Noil, 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 weight average molecular weight in excess of about 200,000, generally between about 200,000 and about 1 ,000,000. Specific examples include polydimethylsiloxane, polydimethylsiloxane methylvinylsiloxane) copolymer, polydimethylsiloxane 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-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 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 (CH₃)₃SiO₀.₅; D denotes the difunctional unit (CH₃)₂SiO; T denotes the trifunctional unit (CH₃)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 above, 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 conditioning agents which are useful herein include Dimethicone with tradename DC200, 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.

A preferred organo-monophosphonic acid is 2-phosphonobutane-1 ,2,4- tricarboxylic acid commercially available from Bayer under the trade name of Bayhibit. Dispersant Polymers

Suitable polymeric dispersing agents include polymeric polycarboxylates and polyethylene glycols, although others known in the art can also be used. It is believed, though it is not intended to be limited by theory, that polymeric dispersing agents enhance overall rinsing performance. Polymeric polycarboxylate materials can be prepared by polymerizing or copolymerizing suitable unsaturated monomers, preferably in their acid form. Unsaturated monomeric acids that can be polymerized to form suitable polymeric polycarboxylates include acrylic acid, maleic acid (or maleic anhydride), fumaric acid, itaconic acid, aconitic acid, mesaconic acid, citraconic acid and methylenemalonic acid. The presence in the polymeric polycarboxylates herein of monomeric segments, containing no carboxylate radicals such as vinylmethyl ether, styrene, ethylene, etc. is suitable provided that such segments do not constitute more than about 40% by weight.

Particularly suitable polymeric polycarboxylates can be derived from acrylic acid. Such acrylic acid-based polymers which are useful herein are the water- soluble salts of polymerized acrylic acid. The average molecular weight of such polymers in the acid form preferably ranges from about 2,000 to 10,000, more preferably from about 4,000 to 7,000 and most preferably from about 4,000 to 5,000. Water-soluble salts of such acrylic acid polymers can include, for example, the alkali metal, ammonium and substituted ammonium salts. Soluble polymers of this type are known materials.

Acrylic/maleic-based copolymers may also be used as a preferred component of the dispersing/anti-redeposition agent. Such materials include the water-soluble salts of copolymers of acrylic acid and maleic acid. The average molecular weight of such copolymers in the acid form preferably ranges from about 2,000 to 100,000, more preferably from about 5,000 to 75,000, most preferably from about 7,000 to 65,000. The ratio of acrylate to maleate segments in such copolymers will generally range from about 30:1 to about 1 :1 , more preferably from about 10:1 to 2:1. Water-soluble salts of such acrylic acid/maleic acid copolymers can include, for example, the alkali metal, ammonium and substituted ammonium salts. Soluble acrylate/maleate copolymers of this type are known materials which are described in European Patent Application No. 66915, published Dec. 15, 1982, as well as in EP 193,360, published Sep. 3, 1986, which also describes such polymers comprising hydroxypropylacrylate. Still other useful dispersing agents include the maleic/acrylic/vinyl alcohol terpolymers. Such materials are also disclosed in EP 193,360, including, for example, the 45/45/10 terpolymer of acrylic/maleic/vinyl alcohol.

Polyaspartate and polyglutamate dispersing agents may also be used, especially in conjunction with zeolite builders. Dispersing agents such as polyaspartate preferably have a molecular weight (avg.) of about 10,000.

A group of preferred clay soil removal/anti-redeposition agents are the cationic compounds disclosed in European Patent Application 111 ,965, Oh and Gosselink, published June 27, 1984. Other clay soil removal/antiredeposition agents which can be used include the ethoxylated amine polymers disclosed in European Patent Application 111 ,984, Gosselink, published June 27, 1984; the zwitterionic polymers disclosed in European Patent Application 112,592, Gosselink, published July 4, 1984; and the amine oxides disclosed in U.S. Patent 4,548,744, Connor, issued October 22, 1985. Other clay soil removal and/or anti- redeposition agents known in the art can also be utilized in the compositions herein. Another type of preferred anti-redeposition agent includes the carboxymethylcellulose (CMC) materials. Builders

The rinse aid used in the compositions of the present invention may also comprise builders to assist in controlling mineral hardness. Inorganic as well as organic builders can be used.

Inorganic or P-containing builders include, but are not limited to, the alkali metal, ammonium and alkanolammonium salts of polyphosphates (exemplified by the tripolyphosphates, pyrophosphates, and glassy polymeric meta-phosphates), phosphonates, phytic acid, silicates, carbonates (including bicarbonates and sesquicarbonates), sulphates, and aluminosilicates. However, non-phosphate builders are required in some locales. Importantly, the compositions herein function surprisingly well even in the presence of the so-called "weak" builders (as compared with phosphates) such as citrate, or in the so-called "underbuilt" situation that may occur with zeolite or layered silicate builders. Examples of silicate builders are the alkali metal silicates, particularly those having a Si02 :Na20 ratio in the range 1.6:1 to 3.2:1 and layered silicates, such as the layered sodium silicates; NaSKS-6 is the trademark for a crystalline layered silicate marketed by Hoechst (commonly abbreviated herein as "SKS-6"). Unlike zeolite builders, the Na-SKS-6 silicate builder does not contain aluminum. Na-SKS-6 has the delta-Na2 Si05 morphology form of layered silicate. SKS-6 is a highly preferred layered silicate for use herein, but other such layered silicates, such as those having the general formula NaMSix 02x+1.yH2 O wherein M is sodium or hydrogen, x is a number from 1.9 to 4, preferably 2, and y is a number from 0 to 20, preferably 0 can be used herein. Various other layered silicates from Hoechst include NaSKS-5, NaSKS-7 and NaSKS-1 1 , as the alpha, beta and gamma forms. As noted above, the delta-Na2 Si05 (NaSKS-6 form) is most preferred for use herein.

Aluminosilicate builders are useful in the present invention. Useful aluminosilicate ion exchange materials are commercially available. These aluminosilicates can be crystalline or amorphous in structure and can be naturally-occurring aluminosilicates or synthetically derived. A method for producing aluminosilicate ion exchange materials is disclosed in U.S. Pat. No. 3,985,669, Krummel, et al, issued Oct. 12, 1976. Preferred synthetic crystalline aluminosilicate ion exchange materials useful herein are available under the designations Zeolite A, Zeolite P (B), Zeolite MAP and Zeolite X. Particularly preferred is Zeolite A. Dehydrated zeolites may also be used herein. Preferably, the aluminosilicate has a particle size of about 0.1-10 microns in diameter.

Citrate builders, e.g., citric acid and soluble salts thereof (particularly sodium salt), are polycarboxylate builders of particular importance for liquid detergent formulations due to their availability from renewable resources and their biodegradability.

Also suitable in the compositions of the present invention are the 3,3- dicarboxy-4-oxa-1 ,6-hexanedioates and the related compounds. Useful succinic acid builders include the C5 -C20 alkyl and alkenyl succinic acids and salts thereof. A particularly preferred compound of this type is dodecenylsuccinic acid. Specific examples of succinate builders include: Iaurylsuccinate, myristylsuccinate, palmitylsuccinate, 2-dodecenylsuccinate (preferred), 2- pentadecenylsuccinate, and the like. Laurylsuccinates are the preferred builders of this group. Fatty acids, e.g., C12 -C18 monocarboxylic acids, can also be incorporated into the compositions alone, or in combination with the aforesaid builders, especially citrate and/or the succinate builders, to provide additional builder activity.

In situations where phosphorus-based builders can be used, the various alkali metal phosphates such as the well-known sodium tripolyphosphates, sodium pyrophosphate and sodium orthophosphate can be used. Phosphonate builders such as ethane-1-hydroxy-1 ,1-diphosphonate and other known phosphonates can also be used. ADDITIONAL COMPONENTS A wide variety of other additional components can be formulated into the present compositions. These include: other conditioning agents such as hydrolysed collagen with tradename Peptein 2000 available from Hormel, vitamin E with tradename Emix-d available from Eisai, panthenol available from Roche, panthenyl ethyl ether available from Roche, hydrolysed keratin, proteins, plant extracts, and nutrients; preservatives such as methyl chloroisothiazolinone, methyl isothiazolinone, benzyl alcohol, methyl paraben, propyl paraben and imidazolidinyl urea; thickeners such as hydroxyethyl cellulose, hydroxypropyl methylcellulose, polyacrylamide, and cetyl hydroxyethyl cellulose; salts, in general, such as potassium acetate and sodium chloride; coloring agents, such as any of the FD&C or D&C dyes; perfumes; ultraviolet and infrared screening and absorbing agents such as octyl salicylate; antidandruff agents such as zinc pyridinethione; and optical brighteners, for example polystyrylstilbenes, triazinstilbenes, hydroxycoumarins, aminocoumarins, triazoles, pyrazolines, oxazoles, pyrenes, porphyrins, imidazoles, and mixtures thereof.
