Abstract: The invention relates to hair care compositions which comprise liposomes that contain 19-methyleicosanoic acid (19-MEA), an emulsion that contains 19 MEA, and a dispersion of liposomes containing 19-MEA in an emulsion. More specifically, we have now found that liposomes or nonionic surfactant vesicles (nsv's or NSV's) can be formed which are storage-stable and possess an affinity for hair. When included in a hair treatment composition, these liposomes deposit on the hair and some liposomes or liposomal fragments remain on the hair during rinsing or if not rinsed-off, such as, with a leave-on composition, and enhance the deposition on the hair of active ingredient 19-MEA with which they are combined.

Abstract: A hair shampoo composition comprising a cleansing surfactant; a water-insoluble hair treating compound, like a hair conditioner or an antidandruff agent; a suspending agent comprising an amine including at least one long carbon chain and a suitable acid; and a suitable carrier, and a method of treating hair are disclosed. The shampoo compositions effectively suspend the water-insoluble hair-treating compound, effectively cleanse the hair and effectively deliver the water-insoluble hair-treating compound to the hair or scalp.

Abstract: An opacifier comprising an amine including at least one carbon chain of at least 16 carbon atoms or a fancy amidoamine having an alkyl group including at least about thirteen carbon atoms, and a suitable acid is disclosed. The opacifier is a salt of the long-chain amine and effectively opacifies, or pearlizes, water-based compositions, such as hair treating compositions, like shampoos, conditioners, conditioning shampoos and antidandruff shampoos; and skin treating compositions, like conditioners, moisturizers and topical medicaments.

Abstract: An opacifier comprising an amine including at least one carbon chain of at least 16 carbon atoms or a fatty amidoamine having an alkyl group including at least about thirteen carbon atoms, and a suitable acid is disclosed. The opacifier is a salt of the long-chain amine and effectively opacifies, or pearlizes, water-based compositions, such as hair treating compositions, like shampoos, conditioners, conditioning shampoos and antidandruff shampoos; and skin treating compositions, like conditioners, moisturizers and topical medicaments.

Abstract: A hair setting composition that includes a water-insoluble amino- or substututed amino-containing compound, such as octylamine or an amino-functionalized silicone, and an ionizable metal salt, wherein the metal has a valence of at least II, such as aluminum chloride or zinc chloride, in a molar or molar-equivalent ratio of ionizable metal salt to water-insoluble amino-containing compound of at least 1:1, and having a pH in the range of about 2.7 to about 4.5, to provide unexpectedly durable hair set retention properties after application to human hair.

Abstract: Enzyme-containing compositions having improved stability and enzymatic activity in aqueous medium, comprising an enzyme and certain aminated polysaccharides, such as aminated cellulose and aminated starch. Enzymatic detergent compositions comprising certain organic surface-active agents in combination with enzymes and aminated polysaccharides are disclosed as well.

Abstract: Hair bleaching compositions containing arginine or various proteins or polypeptides having a high arginine content, a peroxide compound and a bleaching accelerator as essential components.

Abstract: An enzyme-based oxidative process for coloring hair wherein the hair is exposed to a solution having a pH of about 4 to about 10 and containing hydrogen peroxide, soybean peroxidase enzyme and one or more oxidation dye precursors.
