Abstract: A hair treatment composition for straightening hair. The composition comprises: i) 0.1 to 7.9 wt % of the total formulation of a sugar lactone; and ii) cationic surfactant of formula (1): [N(R1)(R2)(R3)(R4)]+(X)? in which R1, R2, R3, and R4 are independently selected from (a) an aliphatic group of from 1 to 22 carbon atoms, or (b) an aromatic, alkoxy, polyoxyalkylene, alkylamido, hydroxyalkyl, aryl or alkylaryl group having up to 22 carbon atoms; and X is a salt-forming anion selected from halogen, acetate, citrate, lactate, glycolate, phosphate nitrate, sulphate, and alkylsulphate.

Abstract: A delivery system comprising an active agent encapsulated by a polymeric film comprising a polymeric backbone derived from a polymer which is water soluble, and one or more derivatising groups attached to the backbone, the derivatising group(s) being derived from a parent material having a ClogP of from 0.5 to 6, the delivery system also comprising a surfactant on the outside of the polymeric film.

Abstract: Hair treatment compositions comprise: at least one polymer comprising at least two hydrogen-bonding moieties, which may be the same or different, covalently bonded to each other by at least one polymeric, oligomeric or monomeric linker, each moiety having at least 3 groups capable of forming a hydrogen bond with the same moiety or a different moiety; and from 0.1 to 50% by weight of the total composition of a hair conditioning agent and/or a cosmetically acceptable surfactant.
