Description

CONDITIONING SHAMPOO COMPOSITIONS COMPRISING QUATERNARY POLYALKOXYLATED POLYALKYLENEAMINE

TECHNICAL FIELD

The present invention relates to conditioning shampoo compositions comprising quaternary polyalkoxylated polyalkyleneamine.

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 conditioning and moisturizing components. The hair can further be left with increased levels of static upon drying, which can interfere with combing and result in a condition commonly referred to as "flyaway hair."

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 cleanse and condition the hair from a single product. Hair conditioners are typically applied in a separate step following shampooing. The hair conditioners are either rinsed-off or left-on, depending upon the type of product used. Hair conditioners, however, have the disadvantage of requiring a separate and inconvenient treatment step. Conditioning shampoos are highly desirable products because they are convenient for consumers to use by providing cleansing and conditioning benefits to the hair in one step.

In order to provide hair conditioning benefits in a cleansing shampoo base, a wide variety of conditioning actives have been proposed. However, they have not been totally satisfactory for a variety of reasons. One problem relates to compatibility between anionic detersive surfactants and the many conventional cationic conditioning agents. Whereas efforts have been made to minimize adverse interaction through the use of alternative surfactants, it remains highly desirable to utilize anionic surfactants to some extent because of its overall superior cleaning properties. On the other hand, some consumers desire mild or non-stimulating shampoo compositions which usually comprise other classes of surfactants in addition to said anionic surfactants. Thus, a conditioning agent which is compatible with a wide variety of detersive surfactants is desired.

Materials which can provide improved overall conditioning benefits while maintaining cleaning performance with the use of anionic detersive surfactants are silicone conditioning agent However, conditioning shampoos comprising silicone conditioning agents have a tendency of leaving the hair feeling coated, heavy, or soiled after the hair is dried. Further, in order to provide a well dispersed, storage stable shampoo composition including silicone conditioning agents, a silicone suspending agent such as acyl derivatives or long chain amine oxide is required. The combination of silicone conditioning agents and its suspending agents often provide a formulation which is relatively viscous and milky in appearance. However, in view of the various consumer needs, shampoos of less viscosity or transparent appearance are also desired. It would be desirable to provide a conditioning shampoo composition that would provide improved overall conditioning benefits with or without silicone conditioning agents.

It is believed that excellent overall conditioning benefits of a conditioning shampoo is achieved by the balance of good deposition of the conditioning agent to the hair and good cleaning properties. Good deposition of the conditioning agent results in soft and smooth feel of the hair after drying, which also positively effects easy dry combing. Good cleaning properties result in absence of negatives such as hair feeling coated, heavy, or soiled.

In the present invention new classes of conditioning agents; quaternary polyalkoxylated polyalkyleneamines; have been developed which are water soluble and compatible with a wide variety of components commonly formulated in conditioning shampoos, particularly with detersive surfactants, which provide good cleaning properties. Further, the quaternary polyalkoxylated polyalkyleneamines of the present invention provide improved overall conditioning benefits with or without silicone conditioning agents. Particularly, conditioning benefits such as wet and dry hair conditioning benefits recognized by the consumer as soft and smooth feel of the hair and easy dry combing; and absence of coated, heavy, or soiled hair feel, are improved.

SUMMARY The present invention relates to conditioning shampoo compositions comprising an quaternary polyalkoxylated polyallcyleneamine and one or more detersive surfactant.

In further embodiments, the present invention relates to a conditioning shampoo composition comprising by weight, from about 0.01% to about 10% of quaternary polyalkoxylated polyalkyleneamine, from about 0.01% to about 20% of a cationic surfactant conditioning agent, from about 5% to about 50% of a detersive surfactant, and from about 20% to about 90% of water. Such compositions satisfy the need for a conditioning shampoo composition with improved overall conditioning benefits with or without silicone conditioning agents, and/or a conditioning shampoo composition with good cleaning properties.

These and other objects and benefits as may be discussed or apparent may be obtained with the present invention, which is described below.

DETAILED DESCRIPTION

All percentages herein are by weight of the compositions unless otherwise indicated. All ratios are weight ratios unless otherwise indicated. All percentages, ratios, and levels of ingredients referred to herein are based on the actual amount of the ingredient, and do not include solvents, fillers, or other materials with which the ingredient may be combined as commercially available products, unless otherwise indicated.

The invention hereof can comprise, consist of, or consist essentially of the essential elements described herein as well as any of the preferred or optional ingredients also described herein. QUATERNARY POLYALKOXYLATED POLYALKYLENEA.MINE The quaternary polyalkoxylated polyalkyleneamine of the present invention can be described by the following formula:

A A R¹ N+ (CH₂)_n N+ R² 2X"

I I

A A wherein R¹ and R² are independently CH3, CH2CH2OH or CH2CH(OH)CH3, n is an integer of from 1 to about 20; A is a polyalkoxy of the formula (R*O)_mH wherein R³ is a C2 to C4 alkylene, and m is an integer from 2 to about 100; and X is a salt-forming anion selected from the group consisting of chloride, bromide, acetate, citrate, lactate, glycolate, phosphate nitrate, sulfonate, sulfate, alkyl sulfate, and alkyl sulfonate radicals. R' and R² are preferably CH3; n is preferably from 2 to about 10, more preferably 4 to 8; and A is preferably a polyethoxy or polypropoxy, most preferably a polyethoxy; and m is preferably from about 10 to about 80, more preferably from about 20 to about 60. The total of the polyalkoxy moieties constitute more than about 50% by molecular weight, more preferably 70% most preferably 80% of the entire molecule. These quaternary polyalkoxylated polyalkyleneamines are water soluble and compatible with any detersive surfactant including anionic detersive surfactants, and also provide excellent conditioning benefits to the hair. Without being bound by theory, at most wash pH's, it is believed that the nitrogen atoms of these compounds are quaternized. This quaternization is believed to aid in the adsoφtion of the compound onto the negatively charged layers of the hair. Such adsoφtion is believed to provide conditioning benefits similar to that obtained by cationic conditioning agents. It is also believed that, when the hydrophilic alkoxy units of the compound meet an abundant amount of water in the rinsing process, the compound loses its cohesive character so that excess quaternary polyalkoxylated polyalkyleneamine is removed from the hair Consequent) , the hair is not left feeling coated, heavy, or soiled

The pH of the present compositions generally will be from about 2 to about 9, preferably from about 5 to about 7

Exemplary quaternary polyalkoxylated polyalkyleneamines are quateπuzed forms of polyethoxylated and polypropoxylated, pentylenediamine, n-butylenediamme, hexamethylenediamine, heptamethylenediamine, and octamethylenediamine A highly preferred compound is chJoπde salt of quaternary polyethoxylated hexamethyleneamine wherein m is an integer of from about 20 to about 60, as shown below

It is not intended to exclude emulsifying surfactants from the present invention, provided the surfactant also possesses sufficient detersive properties to be useful herein

The detersive surfactants will generally compπse from about 5% to about 50%, preferably from about 8% to about 30% and more preferably from about 10% to about 25%, by weight of the composition Anionic Surfactants

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, 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. (New York, New York, USA), 1988 (ISBN 0-89573-399-0), which is incorporated by reference herein in its entirety. In the alkyl and alkyl ether sulfates described above, preferably R has from about 12 to about 18 carbon atoms in both the alkyl and alkyl ether sulfates. The alkyl ether sulfates are typically made as condensation products of ethylene oxide and monohydric alcohols having from about 8 to about 24 carbon atoms. The alcohols can be derived from fats, e.g., coconut oil, palm oil, tallow, or the like, or the alcohols can be synthetic. Lauryl alcohol and straight chain alcohols derived from coconut oil and palm oil are preferred herein. Such alcohols are reacted with 1 to about 10, and especially about 3, molar proportions of ethylene oxide and the resulting mixture of molecular species having, for example, an average of 3 moles of ethylene oxide per mole of alcohol, is sulfated and neutralized.

Specific examples of alkyl ether sulfates which can be used in the present invention are sodium and ammonium salts of coconut alkyl triethylene glycol ether sulfate; tallow alkyl triethylene glycol ether sulfate, and tallow alkyl hexaoxyethylene sulfate. Highly preferred alkyl ether sulfates are those comprising a mixture of individual compounds, said mixture having an average alkyl chain length of from about 12 to about 16 carbon atoms and an average degree of ethoxylation of from 1 to about 4 moles of ethylene oxide. Such a mixture also comprises from 0% to about 20% by weight Cj2-13 compounds; from about 60% to about 100% by weight of C 4._j5. 6 compounds, from 0% to about 20% by weight of C_j7._jg._j9 compounds; from about 3% to about 30% by weight of compounds having a degree of ethoxylation of 0; from about 45% to about 90% by weight of compounds having a degree of ethoxylation of from 1 to about 4; from about 10% to about 25% by weight of compounds having a degree of ethoxylation of from about 4 to about 8; and from about 0.1% to about 15% by weight of compounds having a degree of ethoxylation greater than about 8. Other suitable anionic surfactants are the water-soluble salts of organic, sulfuric acid reaction products of the general formula [RJ-SO3-M] where R_j is selected from the group consisting of a straight or branched chain, saturated aliphatic hydrocaibon radical having from about 8 to about 24, preferably about 10 to about 18, carbon atoms; and M is as previously described above in this section. Examples of such surfactants are the salts of an organic sulfuric acid reaction product of a hydrocarbon of the methane series, including iso-, neo-, and n-paraffins, having about 8 to about 24 carbon atoms, preferably about 12 to about 18 carbon atoms and a sulfonating agent, e.g., SO3, H2SO4, obtained according to known sul- fonation methods, including bleaching and hydrolysis. Preferred are alkali metal and ammonium sulfonated C Q. S n-paraffins.

Still other suitable anionic surfactants are the reaction products of fatty acids esterified with isethionic acid and neutralized with sodium hydroxide where, for example, the fatty acids are derived from coconut or palm oil; or sodium or potassium salts of fatty acid amides of methyl tauride in which the fatty acids, for example, are derived from coconut oil.

Other suitable 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 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 alpha-olefins from which the olefin sulfonates are derived are mono-olefins having about 12 to about 24 carbon atoms, preferably about 14 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 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 alpha-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.

These conditioning agents are comprised at a level of from about 0.01% to about 20% of the conditioning shampoo composition of the present invention.

Water Soluble Cationic Polymers

Water soluble cationic polymers are useful herein. By "water soluble" is meant 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, i.e. distilled or equivalent, at 25°C. Preferably, the polymer will be sufficiently soluble to form a substantially clear solution at a 0.5% concentration, more preferably at a 1.0% concentration.

The water soluble 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. The cationic polymers will generally have cationic nitrogen-containing moieties such as quaternary ammonium or cationic amino moieties, and mixtures thereof.

The cationic charge density is preferably at least about 0.1 meq/gram, more preferably at least about 0.2 meq/gram, and preferably less than about 3.0 meq/gram, more preferably less than about 2.75 meq/gram.

The cationic charge density of the cationic polymer can be determined according to the Kjeldahl Method, which is well-known to those skilled in the art. Those skilled in the art will recognize that the charge density of amino-containing polymers can 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 water soluble cationic polymers so long as the water solubility criteria is met. Suitable counterions include halides (e.g., 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 water soluble cationic polymer can comprise copolymers, terpolymers, etc. of quaternary ammonium or cationic amine-substituted monomer units and other non-cationic units referred to herein as spacer monomer units. Such polymers are known in the art, and a variety can be found in International Cosmetic Ingredient Dicitonary, Fifth Edition, 1993, which is incorporated by reference herein in its entirety.

Suitable water soluble cationic polymers include, for example, copolymers of vinyl monomers having cationic amine or quaternary ammonium functionalities with water soluble spacer monomers such as acrylamide, methacrylamide, alkyl and dialkyl acrylamides, alkyl and dialkyl methaciγlamides, alkyl aciylate, alkyl methacrylate, vinyl caprolactone, and vinyl pyrrolidone. The alkyl and dialkyl substituted monomers preferably have C1-C7 alkyl groups, more preferably C1-C3 alkyl groups. Other suitable spacer monomers include vinyl esters, vinyl alcohol (made by hydrolysis of polyvinyl acetate), maleic anhydride, propylene glycol, and ethylene glycol.

The cationic amines can be primary, secondary, or tertiary amines, depending upon the particular species and the pH of the composition. In general, secondary and tertiary amines, especially tertiary amines, are preferred.

Amine-substituted vinyl monomers can be polymerized in the amine form, and then optionally can be converted to ammonium by a quaternization reaction. Amines can also be similarly quatemized subsequent to formation of the polymer. For example, tertiary amine functionalities can be quatemized by reaction with a salt of the formula R'X wherein R' is a short chain alkyl, preferably a C\-Cη alkyl, more preferably a C1-C3 alkyl, and X is an anion which forms a water soluble salt with the quatemized ammomum. Suitable cationic amino and quaternary ammonium monomers include, for example, vinyl compounds substituted with dialkyiaminoalkyl acrylate, dialkyiaminoalkyl methacrylate, monoalkyl- aminoalkyl acrylate, monoalkylaminoalkyl methacrylate, trialkyl methacryloxyalkyl ammonium salts, trialkyl aciyloxyalkyl ammonium salts, diallyl quaternary ammonium salts, and vinyl quaternary ammomum monomers having cyclic cationic nitrogen-containing rings such as pyridinium, imidazolium, and quatemized pyrrolidone, e.g., alkyl vinyl imidazolium, alkyl vinyl pyridinium, alkyl vinyl pyrrolidone salts. The alkyl portions of these monomers are preferably lower alkyls such as the C1-C3 alkyls, more preferably Cl and C2 alkyls. Suitable amine-substituted vinyl monomers for use herein include dialkyiaminoalkyl acrylate, dialkyiaminoalkyl methacrylate, dialkyiaminoalkyl acrylamide, and dialkyiaminoalkyl methacrylamide, wherein the alkyl groups are preferably C1-C7 alkyl and more preferably C1-C3, alkyl.

The water soluble cationic polymers hereof can comprise mixtures of monomer units derived from amine- and/or quaternary ammonium-substituted monomer and/or compatible spacer monomers.

I I I R R R wherein R is alkyl or aryl, and x is an integer from about 7 to about 8,000. "A" represents groups which block the ends of the silicone chains. The alkyl or aryl groups substituted on the siloxane chain (R) or at the ends of the siloxane chains (A) 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 A groups include hydroxy, methyl, methoxy, ethoxy, propoxy, and aryloxy. The two R groups on the silicon atom may represent the same group or different groups. Preferably, the two R groups represent the same group. Suitable R groups include methyl, ethyl, propyl, phenyl, methyiphenyl and phenylmethyl.

References disclosing suitable nonvolatile dispersed silicones include U.S. Patent No. 2,826,551, to Geen; U.S. Patent No. 3,964,500, to DrakofT, 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 "Silicon Compounds" distributed by Petrarch Systems, Inc., 1984. This reference provides an extensive, though not exclusive, listing of suitable silicones. Another 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 silicones. This overlap is not intended as a limitation on any of these materials. Silicone gums are described by Petrarch, ϋ, 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. AH of these described references are incorporated herein by reference in their entirety. 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, (polydimethylsiloxane) (methylvinylsiloxane) copolymer, poIy(di- methylsiloxane) (diphenyl siloxane)(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 trifunctional and tetrafunctional silanes with monofunctional or difunctional, 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 methylvinyl-chlorosilanes, and tetra- chlorosilane, 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 silicones 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 polymethylsiisequioxane, which is commercially available as Tospearl^M f_rom Toshiba Silicones.

Background material on silicones, including sections discussing silicone fluids, gums, and resins, as well as the manufacture of silicones, 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 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 make up the silicone. Briefly, the symbol M denotes the monofunctional unit (C^^SiO) 5; D denotes the difunctional unit (Q-T-^SiO; T denotes the trifunctional unit (O SiO_j 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 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 M¹ in a silicone resin is indicative of higher levels of crosslinking.
