    摘要： A process for making a polysiloxane block copolymer which is built up from units of the formula [A] [B], in which A is a polymeric block built up from radically polymerisable monomer, and B is a polysiloxane block, the process comprising the steps of polymerising a radically polymerisable monomer in the presence of an atom transfer radical initiator to form an polymer which is end-functionalized with a leaving group capable of nucleophilic substitution by nucleophilic end-groups on a polysiloxane, and reacting the polymer with a polysiloxane having nucleophilic end-groups so that a polysiloxane block copolymer is formed via a nucleophilic displacement reaction between the end-groups on the polysiloxane and leaving groups on the polymer respectively. Also provided is a cosmetic and personal care composition, such as a hair styling composition, comprising the polysiloxane block copolymer as described above.

    摘要： 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 fibre targeting group which is covalently linked to the polymeric backbone, the hair fibre targeting group being a non-cationic species which is capable of specifically interacting with the protein surface of the hair fibre 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
