Water-based, hair care products containing homogeneous terpolymers having both hair styling and conditioning properties is described.

Water-based, hair care products containing homogeneous terpolymers having both hair styling and conditioning properties

What is described herein are conditioning/styling terpolymers of vinylpyrrolidone (VP), dimethylaminopropyl methacrylamide (DMAPMA) and C,-C,alkyl dimethylaminopropyl methacrylic acid quaternized monomers (QDMAPMA), in a defined compositional range. Hair and skin care compositions which include these terpolymers exhibit advantageous low tackiness and high humidity resistance.

Conditioning/styling terpolymers

A homogeneous terpolymer of random monomer distribution containing (a) from abut 32 to about 90% of an N-vinyl lactam, (b) from about 0.5 to about 20% of a mono- or di-functional polysiloxane and (c) from about 5 to about 48% of quaternized or non-quaternized dimethylaminoalkyl-acrylate, methacrylate, acrylamide or methacrylamide combined to form a 100% terpolymer having an excess of vinyl lactam moiety with respect to (c); which terpolymer is useful in a personal care applications, particularly as a hair fixative and conditioner where colorless and clear film forming properties of the terpolymer provides a superior silky, lustrous appearance to the hair without altering hair color or shade, particularly without alteration to dyed or bleached hair.

A process is described for making substantially homogeneous polymers of at least two monomers having substantially differing reactivity rates.

Process for making substantially homogeneous polymers

A process is described for making substantially homogeneous copolymers comprising 20-99% of vinyl pyrrolidone (VP) and 1-80% of N-3,3-dimethylaminopropyl methacrylamide, (DMAPMA), preferably 50-95% VP and 5-50% DMAPMA, and, most preferably, about 80:20, by weight, having a weight average molecular weight of about 200,000 to 1,500,000, as a clear, low viscosity aqueous solution of the homogeneous copolymer, at a 5-20% solids level, preferably about 10-15%, by weight of the solution, having a viscosity of about 5,000 to 80,000 cps, preferably about 10,000 to 70,000 cps. The solution obtained herein has lower viscosity and better clarity, and provides hair care products with enhanced curl retention (hold), when compared to non-homogeneous copolymers of the same composition, or related existing commercial products.

Process for making substantially homogeneous copolymers of vinyl

A multicomponent homogeneous polymer of (a) from about 30 to about 90 wt. % of a N-vinyl lactam, (b) from about 5 to about 30 wt. % of a quaternized and/or non-quaternized aminoalkylacrylic -ester and/or -amide, (c) from about 0.5 to about 30 wt. % of an unsaturated monomer selected from the group consisting of an acrylic ester or amide having a C.sub.4 to C.sub.22 alkyl group, a C.sub.4 to C.sub.22 .alpha.-olefin, a C.sub.4 to C.sub.22 vinyl ether (VE) and a vinyl ester of a C.sub.2 to C.sub.22 carboxylic acid and (d) from about 1 to about 30 wt. % of an unsubstituted acrylic or methacrylic acid and/or an unsubstituted amide of said acrylic or methacrylic acid and optionally, (e) up to 20 wt. % of a mono- or di-functional polysiloxane; all monomers combined to form a 100% polymer composition of randomly distributed monomers for use in personal care formulations, particularly as a hair fixative where the clear, colorless and conditioning film forming properties of the polymer produces a silky, lustrous appearance to the hair and long lasting styling hold.

A process is described for increasing the viscosity and high humidity curl retention of aqueous solutions of homogeneous copolymers of 20-99% vinyl pyrrolidone (VP) and 1-80% N-3,3-dimethylamino-propyl methacrylamide (DMAPMA). The high viscosity solutions are particularly useful as the active component of hair care products.

Low VOC hair spray resin compositions containing homogeneous terpolymers of vinyl pyrrolidone, vinyl caprolactam and 3-(N-dimethylaminopropyl) methacrylamide are described. The hair spray compositions are made using a solution of the terpolymer which is clear and low in viscosity, and which provides a spray of relative small particle size. The hair spray compositions exhibit an effective high humidity curl retention property.
