Abstract: The present invention concerns an auxochrome substituent for an oxidative dye coupler. The auxochrome substituent enables ready developer reaction with the coupler to form azomethine and leuco dyes. Manipulation of the auxochrome substituent enables a bathochromic or hypsochromic shift of the light absorbance by the azomethine dye formed with the auxochrome substituted coupler.

Abstract: A novel class of 3-halo-1H-indol-4-amine derivatives, particularly for dyeing keratin fibers, the azomethine dyes formed from them, their uses as a coupler for dyeing keratin fibers, hair dyeing compositions comprising them, method of dyeing hair thereof, and a hair dyeing kit thereof are disclosed. The products of the oxidative coupling with hair dye primary intermediates, particularly pyrazole derivative, a p-phenylenediamine derivative, a p-aminophenol derivative, have improved fastness properties over currently used violet-blue to blue azomethine dyes.

Abstract: A cosmetic method for treating strands of hair comprising the subsequent steps of: placing the strands of hair to be treated between two substrates on which a first and second compositions capable of reacting together are applied, and implement for the same. The implement for carrying out the method may comprise a first and a second substrates in the form of strips of material that may be folded over each other such that at least one section of the strands of hair to be treated is sandwiched between the first and second compositions.

Abstract: Aqueous compositions containing about 0.5-10% of at least one salt of a fatty acid amide of an amino acid, and about 0.05-0.2% of a salt of an acrylates/C10-30 alkyl acrylate crosspolymer, or about 0.1-0.75% of a salt of acrylates copolymer, are clear, foamable and ultra-mild on skin. When dispensed by a pump sprayer the compositions afford a dense, uniform, stable foam which when spread on the skin gives an elegant cushioning foam pad effect between the hand and skin.

Abstract: The present invention relates to skin moisturizing compositions comprising a liquid crystal/gel network (LCGN) emulsion system comprising water, cationic emulsifiers, low HLB emulsifiers and emollients. In one aspect, the compositions comprise an emollient component as an occlusive agent, such as a petroleum-derived or a non-petroleum-derived occlusive agent, in the LCGN emulsion system. Additives such as adjuvants, active agents, or excipients may also be included in the compositions of the invention. The compositions of the present invention provide excellent moisturization and improved aesthetics (faster absorbency with more pleasant afterfeel properties) compared with traditionally available moisturizing products having different compositions and components and containing petroleum and/or mineral oil, to which are attributed greasiness and other unpleasant, user-perceived attributes.

Abstract: A process for preparing dye compositions which comprises hydrolyzing an O-protected 5,6-dihydroxyindole with an alkaline material under anaerobic condition and the products made by such process.

Abstract: Processes for conditioning human hair by treatment with selected sulfur containing quaternary ammonium compounds, compositions useful for such processes and novel quaternary compounds useful in the processes.

Abstract: A hair dyeing process which comprises of steps of contacting the hair to be dyed with an aqueous solution of a metal salt that promotes melanogenses in air. Before or after the aforementioned step contacting the hair with a solution of 5,6-dihydroxyindole, rinsing the hair between the two contacting steps, maintaining the contact with the second-used solution until a desired darker color is obtained, rinsing or shampooing the hair, then contacting the hair with a solution of hydrogen peroxide until the desired color shade is obtained, and then again rinsing the hair.

Abstract: Certain dispersant free substituted diaminoanthaquinone colorants are useful in hair dye compositions to more intensely color hair. Coloring kits, mousses, gels, and aerosols may contain the compositions.

Abstract: The present invention relates to a method of imparting a controlled tanning of skin by treating the skin with an aqueous medium containing melanin or a precursor of melanin.

Abstract: A substituted m-aminophenol coupler useful in hair dyeing having the formula ##STR1## and acid addition salts thereof wherein x and y are selected from the group consisting of halogen and the groups OR of which R is the same or different alkyl, aminoalkyl or hydroxyalkyl groups, at least one of x or y being a group OR and a process for preparing these compounds.

Abstract: 5,6-Dihydroxyindole is prepared by the catalytic reductive cyclization of 4,5-dihydroxy-2,.beta.-dinitrostyrene in a single step using hydrogen with a palladium, platinum or rhodium catalyst in a polar hydroxylic reaction system. No reaction byproducts or only a single reaction byproduct are produced. The 4,5-dihydroxy-2,.beta.-dinitrostyrene intermediate can be prepared by the chemoselective debenzylation of 4,5-dibenzyloxy-2,.beta.-dinitrostyrene using trifluoroacetic acid. 5,6-Dihydroxyindole is a useful component in hair dye formulations and as an intermediate in the synthesis of melanin.
