Date Nov. 17, 1988.The cosmetic agent for the treatment of the hair and skin contains macromolecular surface-active, quaternary N-substituted chitosan derivatives having the formula (I) HO[C6H11-x-y-zNO4(R1)x(R2)y(R3)z]pH (1) wherein x is from 0.04-0.4; y is from 0.04-0.92; z is from 0.04-0.92; (x+y+z)</=2; p is an integer from 100-100,000; R1 is acetyl; <IMAGE> <IMAGE> R4 is a C1 to C4-alkyl radical; X is Cl, Br, I or CH3SO4; o is 1-5; n is 5-20. The present invention also comprises chitosan derivatives having the formula (I). The chitosan derivatives are distinguished particularly by their surface-active properties, for example, their foam-forming and emulisyfing properties, and by their hair-setting and hair-conditioning effect.</p> |
