| abstract |
Cosmetic preparations with excellent film-forming or texture-forming properties contain, in addition to the usual components, a chitosan additive obtained from sources other than crustaceans and insects, for example from algae, fungi, yeasts, moulds and lichens. A particularly useful product is obtained by known processes from the culture residues of Fungi imperfecti, such as Aspergillus niger or Mucor cercinelloides, which are produced as waste products of biochemical reactions. |
