Abstract

Clear, aqueous solutions of collagen suitable for the preparation of reconstituted collagen fibres and films are prepared by treating the collagen with a proteolytic enzyme other than collagenase in the presence of a neutral salt of Ca++, Sr++, Ba++, Zn++, Mg++, Cd++ or Mn++ with hydrochloric, sulphuric or thiosulphuric acid and/or a cationic surfactant, e.g. dodecylamine.
