Method for making water-soluble elastin hydrolyzates |
摘要 |
A water-soluble hydrolyzate of elastin, suitable for cosmetological use, is disclosed as is a method for making a water-soluble elastin hydrolyzate from starting materials containing elastin which comprises first subjecting said starting material to acid treatment at a pH below about 4 and at an elevated temperature and then enzymatically degrading the acid-treated material, while in comminuted form, in an aqueous bath in the presence of urea, with an alkaline proteinase having an activity optimum in a range between pH 9 and pH 13, the initial pH of the enzymatic treatment being within the pH range optimum for the enzyme employed.
