Abstract: The invention relates to dye compositions for keratinous fibres, containing:(a) at least one dye precursor belonging to group (A) of single bases chosen from para-phenylenediamines;(b) at least one dye precursor of group (B) of double bases chosen from N,N'-diphenylalkylenediamines;the dye precursors of groups (A) and (B) being chosen so that the intensity of the colour on dyed bleached hair (V.sub.B) and the intensity on dyed permanent-waved bleached hair (V.sub.PB) is such that V.sub.B -V.sub.PB =0.+-.0.5, the values of intensity or "value" being determined according to the Munsell notation, the molar ratio of the single bases of group (A) to the double bases of group (B) being between 3 and 10.

Abstract: Composition for dyeing or bleaching hair, to be mixed with an oxidizing solution at the time of use and containing:(a) a fatty acid soap,(b) a cationic or amphoteric silicone polymer,(c) a cationic surface agent,(d) an alkalifying agent, and(e) a cationic polymer chosen from quaternary polyammonium polymers, quaternized or unquaternized vinylpyrrolidone/dialkylaminoalkyl acrylate or methacrylate copolymers, poly(methacrylamidopropyltrimethylammonium chloride), cationic proteins and polyaminoamides which may crosslinked or alkylated.When these compositions are intended for dyeing hair, they also contain oxidation dye precursors and, if desired, couplers, as well as a reducing agent.This composition, which foams slightly, allows a very easy distribution throughout the hair and it improves the cosmetic properties of the hair, especially its disentangling, and imparts a silky feel thereto.

Abstract: The invention provides a pressurized composition based on cationic and anionic polymers and containing at least one cationic polymer and/or one anionic polymer which foams in aqueous solution, in an aqueous solvent medium such that, in the atmosphere, the composition forms an unstable foam on contact with the hair.

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 wave-setting 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 averages 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 c.c. and the treated hair is rolled. After treatment, the hair holds its shape well and is easy to comb.

Abstract: A sprayable aerosol hair lacquer composition packaged under pressure in an aerosol container comprises a synthetic polymer for fixing the hair, an aliphatic alcohol and as an aerosol propellant a mixture of trifluoromonochloroethane and carbon dioxide and/or nitrous oxide.

Abstract: A process for the permanent reshaping of hair consists in reducing the bisulfide bonds of the keratin by applying a reducing composition containing a cationic polymer and reforming the said bonds by applying an oxidizing composition in the presence of an anionic surface active agent.

Abstract: Hair lacquer compositions in pressurized containers are rendered less inflammable consistently throughout the emptying of the container by incorporating bromotrifluoromethane therein in an amount from 5 to 30% by weight based on the weight of the composition and providing the container with a valve provided with an inlet for additional gas.

Abstract: Aerosol foam compositions which have improved stability and foaming containing 2-14% liquified gas and nitrous oxide propulsive agent, 0.2-6% of a tensio-active amphoteric foaming agent, and 0.2-3% tertiary amino oxide.
