Abstract: A composition and method for using the same which improves curl retention and mechanical properties of human hair. More particularly, hair dressing compositions containing a complex of glyoxal and pentaerythritol and an inert cosmetic carrier are found to enhance the curl retention and mechanical properties of the hair while not causing a substantial color change in bleached or dyed hair.

Abstract: A composition and method for treating the hair and skin characterized by a greasy, unaesthetic appearance to reduce or essentially eliminate this greasy appearance which includes topically applying to a human having hair or skin so characterized a cosmetic composition containing as an active ingredient a cis or trans 3,4-thiolannediol, its cis or trans S-oxide derivatives or its cis or trans S-dioxide derivatives.

Abstract: A cosmetic composition is provided which comprises at least one graft and cross-linked copolymer obtained by copolymerization of:A. at least one non-ionic monomer,B. at least one ionic monomer or N-vinyl pyrrolidone,C. polyethylene glycol, andD. a cross-linking agent selected from ethylene glycol dimethacrylate, diallyl o-, m- and p-phthalates, a divinylbenzene, tetrallyloxyethane and a polyallylsucrose possessing 2 to 5 allyl groups per mol of sucrose, and a cosmetically acceptable vehicle.Such compositions are particularly useful as hair lacquers and wavesetting lotions; they adhere well to the hair while giving a good glossy appearance. Certain of the copolymers are novel.

Abstract: A hair-dressing composition for setting and imparting greater luster to hair which comprises, a hydrophilic polymer containing at least 3% by weight structural units which contain at least one sulfonate group.

Abstract: Copolymers having tertiary amine groups and composed of 16 - 43% methyl methacrylate, 25 - 54% dimethylamino ethyl methacrylate and 12 - 52% octadecyl methacrylate are particularly useful as hair treating resins with conventional carriers and additives. The copolymers can be crosslinked by up to 0.15 by an unsaturated agent to produce preferred copolymers used in wavesetting lotions in amounts of 1 - 3%. Such copolymers can also be partially or wholly quaternized by a quaternizing agent. Those copolymers not crosslinked are particularly useful as hair lacquers, especially in aerosol sprays in amounts of 1 - 4%. The molecular weight for the subject copolymers average 10,000 - 1,500,000 and copolymerization can be effected in a solvent with a catalyst wherein the reaction mixture is heated for about 6 to 24 hours at about 80.degree.C. When applied to the hair, the amount of lotion or lacquer used can be 10 - 100 cc. and the treated hair is rolled.

Abstract: A pressurized package containing a conventional pressure propellant is divided into two compartments arranged for mixing of their contents simultaneously with dispensing, one compartment containing a peroxide solution and the other containing a hair treating composition including certain selected compounds in quantity sufficient to prevent development of unsafe pressure should the peroxide decompose within the package.
