COSMETIC BASED ON N-HYDROXY-PROPYL-ISOPROPYL ETHER DERIVATIVES OF CHITOSANE

摘要

The present invention relates to a cosmetic for the treatment of hair and skin which is characterized by a content of novel N-hydroxy-propyl-isopropyl ether chitosanes consisting of a) 4 to 40 mole percent of monomer units having the formula (I) (I) and b) 60 to 96 mole percent of monomer units having the formula (II) (II), wherein R1 and R2 are identical or different and represent hydrogen or the group , wherein n equals 1 or 2, on the condition that in at least half the units having the formula (II) R1 and R2 do not simultaneously the units having the formula (II) R1 and R2 do not simultaneously represent hydrogen. The present invention also relates to novel N-hydroxy-propyl-isopropyl ether chitosanes.
