| 摘要 |
The present invention relates to a conditioning composition for keratin fibres especially human hair comprising a special cationic polymer. The present inventor has surprisingly found out that an aqueous hair conditioning composition comprising at least one fatty alcohol, at least one emulsifier and at least one cationic polymer with multi cationic sites and ester groups improves hair combability, smoothness shine, elasticity and more interestingly hair treated with such a composition has enough volume and body and manageable. The cationic polymer preferably comprises at least 4 ester groups, at least 3 cationic sites in form of quaternary ammonium groups and 3 alkyl groups with an average chain length of 18 carbon atoms which are one of the alkyl groups of different cationic quaternary ammonium site. Such kind of cationic polymer, and most preferred cationic polymer within the meaning of present invention, is known as Polyquaternium-70.
