摘要：
A novel keratinic polymeric product is described which can be used for cosmetic purposes. This product comprises keratin peptide chains of different molecular weights, formed of amino acids bonded to one another by amide groups with more than 75 percent of the cystine linkages being in the form of S-sulphocysteine, the said peptide chains terminating at one end in a free carboxyl group and at their other end in a free amine group, the major part of said chains having a molecular weight of 1,100 to 7,500.
