摘要: The invention relates to the use of nanoscale chitosanes and/or chitosane derivatives with particle diameters of 10 to 300 nm for producing cosmetic and/or pharmaceutical formulations. Compared to known chitosanes and chitosane derivatives, the particularly small size of the particles of the inventive chitosanes and chitosane derivatives ensures that when applied topically, they rapidly penetrate the stratum corneum of the skin or the keratin fibrillars of the hair.
