Abstract

What is described herein are conditioning/styling polymers of vinyl caprolactam (VCL), vinylpyrrolidone (VP), dimethylaminopropyl methacrylamide (DMAPMA) and optionally C8-C24 alkyl quaternized dimethylaminopropyl (meth)acrylamide or methacrylic acid quaternized monomers (QDMAPMA). Personal care/cosmetic compositions such as hair and skin care compositions which include these polymers exhibit advantageous low tackiness and high humidity resistance.

CONDITIONING/STYLING RESIN

Abstract

            What is described herein are conditioning/styling polymers of vinyl caprolactam (VCL), vinylpyrrolidone (VP), dimethylaminopropyl methacrylamide (DMAPMA) and optionally C8-C24 alkyl quaternized dimethylaminopropyl (meth)acrylamide or methacrylic acid quaternized monomers (QDMAPMA).  Personal care/cosmetic compositions such as hair and skin care compositions which include these polymers exhibit advantageous low tackiness and high humidity resistance.

CONDITIONING/STYLING RESIN

This invention relates to polymers for use in hair and skin care compositions, and, more particularly, to conditioning and styling tetrapolymers having advantageous high humidity resistance, low tackiness and a predetermined cloud point.

            Copolymers of vinylpyrrolidone (VP) and dimethylaminopropyl methacrylamide (DMAPMA) have been used extensively as active components of hair and skin compositions.  While these copolymers are generally suitable polymers for such products as conditioners and shampoos, it is desired to provide new polymers having improved performance characteristics in these and other personal care products.

            What is described herein is a polymer of vinyl caprolactam (VCL), vinylpyrrolidone (VP), dimethylaminopropyl methacrylamide (DMAPMA) and optionally C9-C24 alkyl quaternized dimethylaminopropyl methacrylic acid or quaternized (meth) acrylamide monomers, for use in hair and skin care compositions, which are characterized by particularly high humidity resistance, low tackiness and advantageous high cloud points.

            The polymers of the invention preferably comprise the following four monomers, namely A, B, C and D, and preferably in the compositional ranges by wt.% given below:

                                                                         

vinyl caprolactam                                                                                                      (A)

(5-85%, preferably 55-75%)

or analogs thereof

                                                                         

vinylpyrrolidone                                                                                                          (B)

(5-85%, preferably 20-40%)

or analogs thereof

            CH2=C(R1)-CO-P-R5-N(R3)(R4)                               (0.05-20%,                 (C)
