Cosmetic composition based upon chitosan derivatives, new chitosan derivatives as well as processes for the production thereof

摘要

Cosmetic compositions useful for treatment of hair or skin contain macromolecular glyceryl-chitosan having (a) 4-40 Mol-% units of the Formula (I) and (b) 60-96 Mol-% units of the Formula (II) wherein R1, R2 and R3 are the same or different and are wherein R4 and R5 are the same or different and are wherein either X=H and Y=CH2OH, or Y=H and X=CH2OH and n=2 to 5, with the proviso that for at least half of the units of the formula II, R1, R2 and R3 are not uniformly H, or their salts with organic or inorganic acids, in a suitable cosmetic carrier. Also disclosed are the compounds per se and a process for their production wherein chitosan composed of 60-96% entacetylated chitin is reacted with glycidol.
