O-benzyl-N-hydroxyalkyl chitosan-based nail polish and novel O-benzyl-N-hydroxyalkyl derivatives of chitosan

摘要

A nail lacquer based on a film former, on a resin component and on a solvent system contains as film former and/or resin component an O-benzyl-N-hydroxyalkylchitosan of the general formula (I HO[C6H11-m-qNO4(R1)m(R2)n(R3)q]pH (I (with m = 0 to 0.6, n = 0.1 to 10, q = 0.1 to 4, p is an integer from 50 to 5000, R1 = acetyl, R2 = hydroxyethyl, 2-hydroxypropyl or 2-hydroxybutyl and R3 = benzyl). …??The lacquer films obtained with the nail lacquer have a high gloss, an excellent adhesion and, compared with nail lacquers based on nitrocellulose, increased hardness with adequate elasticity.
