Abstract
The invention provides a hair treatment composition comprising a hair substantive polymer, the hair substantive polymer comprising a polymeric backbone bearing: (a) at least one side chain which is formed from a hair fiber targeting group which is covalently linked to the polymeric backbone, the hair fiber targeting group being a non-cationic species which is capable of specifically interacting with the protein surface of the hair fiber in a non-covalent interaction having a bond energy ranging from 0.5 to 3 Kcal/mol, when the composition is applied to hair; (b) preferably, at least one side chain which is different to side chain (a) and which comprises a hair benefit agent. Compositions of the invention provide for deposition and delivery of benefit agents to hair in a more efficient and targeted manner.
