Description

"HAIR CONDITIONING COMPOSITION CONTAINING A NON-GUAR GALACTOMANAN POLYMER derivative"

FIELD OF INVENTION

The present invention relates to hair conditioning compositions containing a non-guar galactomannan polymer derivative.

BACKGROUND OF THE INVENTION

Human hair gets dirty from contact with the surrounding environment and the sebum secreted by the scalp.

The soiling of the hair causes it to give off a feeling of dirt and to look unattractive.

This tendency of hair to get dirty becomes shampooing with some frequency.

Shampooing cleans hair, removing excess dirt and sebum. However, shampooing can leave your hair wet, tangled, and often in a difficult-to-handle state. When hair dries, it is usually dry, rough, frizzy or armed due to the removal of natural hair oils as well as other natural conditioning and moisturizing components. Hair can also be left with increased levels of static after drying, which can interfere with combing and result in a condition commonly referred to as "frizzy hair", or contribute to the undesirable phenomenon of split ends, particularly in long hair. were developed to condition the hair after shampooing. One common method for providing hair conditioning benefit is the use of conditioning agents such as surfactants and cationic polymers, high melting point fatty compounds, low melting point oils, silicon compounds and mixtures thereof. These conditioning agents are mostly known to provide conditioning benefits upon deposition on the hair. For example, silicone compounds are known to provide conditioning benefits such as softness and smoothness to the hair by depositing on them.

It has been found that it is not yet easy to achieve the expected conditioning efficacy, especially the conditioning benefits such as softness, smoothness and combability, by applying traditional conditioning compositions.

Based on the foregoing arguments, there remains a desire for hair conditioning compositions that provide optimal deposition of the conditioning agent, thereby providing improved conditioning benefits such as smoothness, smoothness and combing.

There is also a desire for rinse-and-rinse hair conditioning compositions that provide optimal silicone deposition, while not negatively affecting other benefits such as slippery and straight-forward shifting on wet hair.

The present invention relates to a hair conditioning composition comprising:

(a) from about 0.01% to about 10% by weight of a non-guar galactomannan polymer derivative has a ratio of mannose to galactose greater than 2: 1 monomer to monomer base, said monomer-polymer derivative. non-guar galactomannan selected from the group consisting of a cationic non-guar degalactomannan polymer derivative and an amphoteric non-guar galactomannan polymer derivative had a positive net charge;

i. said non-guar degalactomannan polymer derivative having a molecular weight of from about 1,000 to about 10,000,000;

ii. said non-guar degalactomannan polymer derivative having a cargacathonic density of from about 0.7 meq / g to about 7 meq / g;

(b) a grouping conditioning agent consisting of cationic surfactants, polymersatonic, nonvolatile silicones, nonvolatile hydrocarbons, quaternary ammonium salts, saturated straight chain C1 to C22 alcohols, nonvolatile hydrocarbon esters and mixtures thereof; and

c) wherein said hair conditioning composition is substantially free of an anionic surfactant. DETAILED DESCRIPTION OF THE INVENTION

While the descriptive report ends with claims that particularly point to and distinctly claim the invention, it is believed that it will be better understood from the following description.

The hair conditioning compositions of the present invention comprise a cationic galactomannan-guar polymer, a conditioning agent and less than about 5% of an anionic surfactant. Each of these essential components, as well as the preferred or optional components, is described in detail later in this document.

All percentages, parts and ratios are based on the total weight of the compositions of the present invention, unless otherwise indicated. All such weights, as matched to related ingredients, are based on the level of the asset and therefore do not include solvents or by-products that may include commercially available materials unless otherwise indicated. The term "weight percent" may be referred to as "weight percent" in this document.

All molecular weights used in the present invention are weight average molecular weights expressed in grams / mol, unless otherwise indicated.

For use in the present invention, the term "substantially free of an anionic surfactant" means that the composition comprises less than 5% by weight of a detersive surfactant. The term "water soluble" for use in the present invention means that the polymer is water soluble in the present composition. Generally, the polymer should be soluble at 25 ° C and at a concentration of at least 0.1% by weight of the water solvent, preferably at least 1%, more preferably at least 5%, and most preferably at least 15%. %.

The term "water insoluble" for use in the present invention means that the compound is not water soluble in the present composition. Therefore, the compound is not miscible with water.

NON-GUAR GALACTOMANAN POLYMER DERIVATIVE

The hair conditioning compositions of the present invention comprise non-guar degalactomannan polymer derivatives having a ratio of mannose and egalactose greater than 2: 1 on a monomer to monomer basis, the non-guarselected galactomannan polymer derivative of the group consisting of a cationic non-guar galactomannan polymer derivative and an amphoteric non-guar galactomannan polymer derivative having a positive liquid charge. For use in the present invention, the term "non-guar cationic galactomannan" refers to a non-guar degalactomannan polymer to which a groupocathionic is added. The term "amphoteric non-guar galactomannan" refers to a non-guar galactomannan polymer to which a cationic group and an anionic group are added such that the polymer has a positive net charge. Non-guar galactomannan polymer derivatives have been found to provide optimal efficacy as conditioning agents.

Optimized conditioning benefits include increased silicon deposition, which results in improved hair smoothness and combability. In addition, non-guar galactomannan polymer derivatives have been found to reduce the overall avidity of the conditioning compositions, which increases the benefits of tactile sensation.

The gum for use in the preparation of the non-guar galactomannan polymer derivatives is typically obtained as a naturally occurring material such as seeds or grains from plants. Examples of diverse non-guar galactomannan polymers include, but are not limited to, tara gum (3 parts mannose / 1 part degalactose), locust bean or mesquite (4 parts mannose / 1 part galactose), and cassia gum (5 parts mannose / 1 partegalactose).

In one embodiment of the present invention, the cationic non-guar galactomannan polymer derivatives have a molecular weight of from about 5,000 to about 3,000,000. For the purposes of the present invention, the term "molecular weight" refers to weight average molecular weight. The weight average molecular weight can be measured by gel permeation chromatography.

The hair conditioning compositions of the present invention include non-guar degalactomannan polymer derivatives having a cargacathonic density of from about 0.7 meg / g to about 7 meq / g. In one embodiment of the present invention, non-guar galactomannan polymer derivatives have a charge density of from about 0.9 meq / g to about 7 meq / g. The degree of disubstitution of the cationic groups on the non-guar degalactomannan structure needs to be sufficient to provide the cationic charge density described above.

In one embodiment of the present invention, the non-guar galactomannan polymer derivative is a cationic non-guar galactomannan polymer derivative which is obtained by splicing between the hydroxyl groups of the galactomannan-guar polymer and quaternary ammonium reactive compounds.

Any anionic counterions may be used for cationic polymers, provided that the water-solubility criterion is met. Suitable counterions include halides (e.g. Cl, Br, I or F, preferably Cl, Br or I), sulfate and methyl sulfate. Others may also be used as this list is not exclusive.

A nitrogen cationic moiety will generally be present as a substituent on a fraction of the total monomeric units of the hair conditioning cationic polymers. Therefore, the cationic polymer may comprise copolymers, terpolymers, etc., of quaternary ammonium or aminacathionic substituted monomeric units and others referred to in this invention as spacer monomeric units. These polymers are known in the art, and several of them can be found in "CTFACosmetic Ingredient Dictionary", 3a. Edition, edited by Estrin, Crosley and Haynes, (The Cosmetic, Toiletry, and Fragrance Association, Inc., Washington, D.C., 1982).

Suitable cationic polymers include, for example, vinyl monomer copolymers having cationic amine or quaternary ammonium functionalities, with water-soluble spacer monomers such as acrylamide, methacrylamide, alkyl and dialkyl acrylamides, alkyl edialkyl methacrylamyl, alkylacrylate acrylate caprolactone vinyl and pyrrolidone vinyl. Substituted alkyl and dialkyl substituted monomers preferably have C1 -C7 alkyl groups, more preferably C1 -C3 alkyl groups. Other suitable monomeric spacers include vinyl esters, alcohol solvin (produced by hydrolysis of polyvinyl acetate), maleic anhydride, propylene glycol and ethylene glycol.

Cationic amines may be primary, secondary or tertiary amines, depending on the specific species and pH of the composition. In general, aminesecondary and tertiary, especially tertiary, are preferred.

The cationic polymers of the present invention may comprise mixtures of amine and / or quaternary ammonium-substituted demonomer derived monomer units and / or compatible spacer monomers.

Suitable cationic hair conditioning polymers include, for example: 1-vinyl-2-pyrrolidone copolymers and 1-vinyl-3-methylimidazolium salt (eg chloride salt) (called in the industry by CTFA ("Cosmetic, Toiletry , and FragranceAssociation ") of polyquaternium-16), such as those available commercially from BASF Wyandotte Corp. (Parsippany, NJ, USA) under the tradename LUVIQUAT (e.g., LUVIQUATFC 370); copolymers of 1-vinyl-2-pyrrolidone and dimethyl amino ethyl methacrylate (referred to as CTFA depolyquaternium-11) as those available commercially from Gaf Corporation (Wayne, NJ, USA) under the tradename GAFQUAT (e.g. GAFQUAT 755N); quaternary ammonium-containing diallyl cationic polymers, including, for example, the dimethyldiallylammonium chloride homopolymer and the acrylamide copolymers and the dimethyldiallylammonium chloride, known in the industry (CTFA) as polyquaternium 6 and epiquiquaternium 7, respectively; and amino acid salts of aminoalkyl esters of homo and unsaturated carboxylic acid copolymers having from 3 to 5 carbon atoms as described in U.S. Patent No. 4,009,256.

As discussed above, the cationic polymer of the present invention is water soluble. This does not mean, however, that said polymer needs to be soluble in the composition. Preferably, however, the cationic polymer is either soluble in the composition or in a complex coacervate phase present in the composition formed by the cationic polymer and anionic material. The complex polymeracacionate coacervates may be formed with anionic surfactants or anionic compolymers which may optionally be added to the compositions of the present invention (e.g. sodium polystyrenesulfonate). However, the present hair conditioning composition is substantially free of anionic detestants. When anionic surfactants are present, they are used in amounts of less than about 5%, preferably less than about 3% and most preferably less than about 2%, by weight of the hair conditioning composition. silicone

The compositions of the present invention may also include non-volatile, soluble or insoluble silicone based conditioning agents. The term "soluble" means that the silicone-based conditioning agent is miscible with the aqueous vehicle of the composition to form part of the same phase.

Preferred, however, are soluble silicones. The insoluble desilicone based hair conditioning agent for use in the present invention will preferably have a viscosity of about 0.001 m 2 / s (1,000 cSt) at about 2 m 2 / s (2,000,000 centistokes) at 25 ° C, with more than preferably from about 0.01 m2 / s (10,000 cSt) to about 1.8 m2 / s (1,800,000 cSt) and more preferably about 0.1 m2 / s (100,000 cSt) about 1.5 m2 / s (1,500,000 cSt). Viscosity can be measured by means of a glass capillary viscometer as demonstrated by the Dow CorningCorporate CTM0004 test method of July 20, 1970.

Suitable non-volatile insoluble silicone fluids include polyalkyl siloxane, polyaryl. siloxanes, polyalkyl aryl siloxanes, polyether siloxane copolymers and mixtures of these items. Other non-volatile insoluble silicone fluids with hair conditioning properties may also be used. For use in the present invention, the term "non-volatile" means that the silicone has a melting point of at least about 260 ° C, preferably at least about 275 ° C, and more preferably at least about 300 ° C. . These materials exhibit very low or insignificant vapor pressure under ambient conditions. The term "desilicone fluid" means fluxable silicone materials having a viscosity of less than 1 m2 / s (1,000,000 centistokes) at 25 ° C. Generally, the viscosity of the fluid will be in the range of about 5E-6 m 2 / s (5 cSt) to 1 m 2 / s (1,000,000 centistokes) at 25 ° C, preferably between about 1 e 5 m / s (10 cSt). ) and about 0.3 m2 / s (300,000 centistokes).

The silicone fluids of the present invention also include polyalkyl or polyaryl siloxanes having the following structure:

<formula> formula see original document page 20 </formula> where R is alkyl or aryl, and x is an integer from about 7 to about 8,000, which may be used. "A" represents groups that block the ends of the silicone chains.

Substituted alkyl or aryl groups on the siloxane (R) chain or at the ends of the siloxane (A) chains may have any structure as long as the resulting silicones remain fluid at room temperature, are hydrophobic, non-irritating, toxic or otherwise modonocative when applied. hair, are compatible with other components of the composition, are chemically stable under normal conditions of use and storage, and are capable of depositing on and conditioning the hair.

Suitable groups A include methyl, methoxy, ethoxy, propoxy and aryloxy. The two R groups on the silicon atom may represent the same or different groups.

Polyalkyl aryl siloxane fluids that may be used also include, for example, polymethyl phenylsiloxanes. Such siloxanes are available, for example, from General Electric Company as SF 1075 methylphenylfluid, or from Dow Corning as 556 Cosmetic Grade Fluid.

Especially preferred to accentuate the shine characteristics of the hair are the highly arylated silicones, such as highly phenylated polyethylene, with refractive indices of about 1.46 or higher, especially about 1.52 or higher. When such high refractive index silicones are used, they need to be mixed with a diffuser, such as a surfactant or a silicone resin, as described hereinafter, to decrease surface tension and enhance the film-forming ability of the material.

Polyether siloxane copolymers which may be used include, for example, a polypropylene oxide-modified polydimethyl siloxane (e.g., DowCorning DC-1248®) although ethylene oxide or mixtures of ethylene oxide and depropylene oxide may also be used. The contents of ethylene oxide and polypropylene oxide need to be low enough to avoid their water solubility and the composition described herein.

References describing silicone fluids include U.S. Patent No. 2,826,551, Geen, U.S. Patent No. 3,964,500, Drakoff, issued June 22, 1976, U.S. No. 4,364,837, Pader and British Patent 849,433, Woolston. Also useful are the silicon compounds distributed by Petrarch Systems, Inc., 1984. These references offer an extensive (but not exhaustive) list of suitable silicone fluids.

Another silicone-based hair conditioner which may be especially useful in silicone-based conditioning agents is insoluble silicone gum. The term "silicone gum" for use in the present invention means polyorganosiloxane materials having a viscosity at 25 ° C greater than or equal to 1 m2 / s (1,000,000 centistokes). Silicone gums are described by Petrarch and others, including US Patent No. 4,152,416, Spitzer et al., Issued May 1, 1979 and Noll, Walter, Chemistry and Technology of Silicones, New York: Academic Press 1968. Silicone gums are also described in General Electric's "Silicone Rubber Product DataSheets" SE 30, SE 33, SE 54 and SE 76 product leaflets. "Silicone gums" typically have a molecular weight above about 200,000 and generally between about 200,000 and about 1,000,000. Specific examples include polydimethylsiloxane, (polydimethyl siloxane) (methyl vinylsiloxane) copolymer, poly (dimethyl siloxane) (diphenylsiloxane) (methyl vinyl siloxane) copolymer, and mixtures thereof.

Preferably, the silicone-based hair conditioning agent comprises a mixture of a depolidymethyl siloxane gum having a viscosity greater than about 1 m2 / s (1,000,000 centistokes) and a polydimethylsiloxane fluid having a viscosity of about 1E-5 m2 / s ( 10 centistokes) at about 0.1 m2 / s (100,000 centistokes), wherein the ratio of gum to fluid is in the range of about 30:70 to about 70:30, preferably about 40: 60 to about 60:40.

An optional ingredient that may be included in the silicone-based conditioning agent is desilicone resin. Silicone resins are highly crosslinked siloxanopolymer systems. Cross-linking is introduced by incorporating etetrafunctional trifunctional silanes with monofunctional, difunctional or both silanes during the manufacture of the silicone resin. As is well understood in the art, the degree of crosslinking required to produce a silicone resin varies according to the specific silane units incorporated into that resin. In general, silicone materials which have a sufficient level of three-dimensional and three-functional three-unit siloxane monomer units and thus a sufficient level of crosslinking to dry as a rigid or hard film are considered silicone resins. The ratio of oxygen atoms to silicon atoms is indicative of the crosslinking of the silicone material. Desilicon materials having at least about 1.1 oxygen atoms per silicon will generally be silicone resins in the present invention. Preferably, the ratio of oxygen to silicon atoms is at least about 1.2: 1.0. Ossilanes used in the manufacture of silicone resin include monomethyl, dimethyl, trimethyl, trimethyl, demonophenyl, methylphenyl diphenyl, monovinyl and demethyl vinyl chloro silanes, the most commonly used methyl silanes being substituted. Preferred resins are available from General Electric under the names GE SS4230 and GE SS4267. Commercially available silicon resins are generally supplied in a form dissolved in a low viscosity volatile or nonvolatile silicone fluid. Silicone resins for the present invention need to be provided and incorporated into the present compositions in such dissolved form as will be apparent to those skilled in the art.

Silicone resins can optimize the deposition of silicone on hair, and can enhance the brightness of the same with high refractive index volumes.

Informational material on silicones, which includes information on silicone fluids, gums and resins, as well as their manufacture, can be found in "Encyclopedia of Polymer Science and Engineering", Volume15, Second Edition, pages 204-308, John Wiley & Sons, Inc., 1989.

Silicone materials and particularly silicone resins may be conveniently identified according to a stenographic nomenclature system known to those skilled in the art as "MDTQ" nomenclature.

Under this system, silicone is described according to the presence of the various units of siloxane monomers that comprise it. Briefly, M denotes the functional unit (CH3) 3Si0), 5, D denotes the difunctional unit (CH3) 2SiO, T denotes the trifunctional unit (CH3) SiOij5 and Qdenota denotes the qadri or tetrafunctional unit SiO2. Pleated unit symbols, such as M ', D', T 'and Q', denote substitutes other than methyl, and need to be specifically defined for each occurrence. Typical alternative substituents include groups such as vinyl, phenyl, amines, hydroxyls, and the like. The molar ratios of the various units, either in terms of subscriptions to symbols indicating the total number of each unit type in silicone (or an average of these values), or as specifically indicated reasons, complete, in combination with molecular weight, the description of the silicone material in the silicone. "MDTQ" system. Higher relative molar amounts of T, Q, T1 and / or Q1 for D, D1, M and / or M1 in a silicone resin indicate higher levels of crosslinking. However, as discussed earlier, the total level of crosslinking can also be indicated by the ratio of oxygen to silicon.

Preferred for use in the present invention are silicone resins MQ, MT, MTQ, MQ and MDTQ. Therefore, the preferred silicone substitute is methyl. Particularly preferred are MQ resins, where M: Q is in the range of from about 0.5: 1.0 to about-1.5: 1.0 and the average molecular weight of the resin is about 1,000 to about 10,000.
