A hair styling and conditioning process comprising the steps of: contacting the hair with a compound having an electrophilic group and at least one hydrophobic group whereby the electrophilic group reacts with nucleophilic sites in and on the hair to give the hair a plurality of hydrophobic groups at the surface, in which the hydrophobic group is selected from the group consisting of C.sub.10-30 and C.sub.10-30 alkenyl groups. Preferably the electrophilic group is azlactone. Also a reversible hair styling process in which the hydrophobic group is selected from the group consisting of C.sub.1-30 alkyl, C.sub.2-30 alkenyl, phenyl, diphenyl, other aromatics, and fluoroalkanes, and the electrophilic group is selected from the group consisting of azlactone, sulphide from disulphide, sulphide from thiosulphonate, vinyl zulphone, vinyl sulphoximines, banzoxazinones and isocyanates. Novel azlactones, including pentadecyl and hexyl azlactone.

Hair styling composition and method

Cosmetic compositions comprising an emulsion, preferably an aqueous emulsion, including at least one cosmetic resin material, e.g. a hydrocarbon resin such as polyisobutylene, are made by direct emulsification of the resin without a solvent or carrier therefor. The direct emulsification may be achieved by a special mixing regime, with particular emulsifiers. The absence of solvent or carrier for the resin material avoids product thinning and gives several manufacturing and processing advantages.

Cosmetic composition comprising particles of polyisobutylene resin and

A cosmetic composition, especially for providing a conditioning benefit to hair, is provided incorporating an azlactone-functionalized copolymer consisting of vinyl azlactone and methacryloyl polydimethylsiloxane monomers.

Cosmetic treatment of substrates

A method for treating hair to impart thereto a conditioning benefit, the method involving applying to the hair an azlactone-functionalised copolymer consisting of vinyl azlactone and methacryloyl polydimethylsiloxane monomers; and allowing the copolymer to chemically bond through nucleophilic reaction of the azlactone onto the hair, the monomers of the copolymer being present in amounts sufficient to achieve both bonding to the hair and imparting conditioning properties.

A hair styling composition for imparting body and/or stylability to hair, comprises (a) at least one of surfactant, conditioning agent and water or other volatile solvent, together with (b) a per-alk(en)yl hydrocarbon material.
