A METHOD FOR PURIFYING AND RECOVERING SILK PROTEINS IN SOLUBLE FORM AND USES THEREOF

摘要

A method for purifying and recovering silk proteins in water-soluble form is described. The method is based upon precipitation of the silk protein at a temperature below room temperature, which results in a protein pellet that redissolves in water without the addition of harsh chemicals. When the precipitation is done at room temperature, the resulting protein pellet cannot be redissolved in water. Applications for the water-soluble silk proteins in cosmetics, skin care, hair care, hair coloring products, and for pigment coating and wound healing bandages are described.
