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

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.

Carboxylic polymers useful in detergent compositions contain keto structural units incorporated into the polymer backbone. The units may be introduced by means of the compound 2,2'-diphenyl-4-methylene-1,3-dioxolane. The polymers show better biodegradability than the acrylic and acrylic/maleic polymers commonly used in detergent compositions, while the detergency building (calcium binding) is comparable or better.
