Abstract

The invention relates to cosmetic agents for treating of hairs or the skin which is characterized by a content of novel quaternary chitosan derivatives of the formula EQU HO[C.sub.6 H.sub.11-m NO.sub.4 (R.sup.1).sub.m (R.sup.2).sub.n (R.sup.3).sub.q ].sub.p H (m=0-0.5; n=0-6; q=0.005-3.0; p=10-50,000; R.sup.1 =acetyl; R.sup.2 =--CH.sub.2 CH(OH)--CH.sub.2 --O--, --CH.sub.2 --CH(CH.sub.2 OH)--O-- or --CH(CH.sub.2 OH)--CH.sub.2 --O--; R.sup.3 = ##STR1## with R.sup.4 =C.sub.1 - to C.sub.4 -alkyl and X=Cl, Br, or CH.sub.3 SO.sub.4. It relates in furtherance to the novel quaternary chitosan derivatives as well as processes for making the same. These chitosan derivatives have a good substantivity, among others, to hair keratin and show hair strengthening and hair conditioning characteristics.
