The invention relates to a cosmetic agent for the treatment of hair and skin, which contains new macromolecular, surface-active, quaternary, N-substituted chitosan derivatives of the formula (I) HO [C₆H 11-xyz NO₄ (R¹) x (R²) y (R³) z ] p H (I), (x = 0.04 - 0.4; y = 0.04 - 0.92; z = 0.04 - 0.92; (x + y + z) ≦ 2; p = 100 - 100,000; R¹ = acetyl ; R⁴ = C₁ to C₄ alkyl; X = Cl, Br, J or CH₃SO₄; o = 1 = 5; n = 5 - 20) is marked.n n n It also relates to the new chitosan derivatives of the formula (I). The new chitosan derivatives are characterized in particular by their surface-active properties, for example their foaming and emulsifying properties, and their hair-setting and hair-conditioning properties. |
