HIGH WATER-RETENTIVE PROTEOGLYCANS, COSMETICS AND METHOD FOR PRODUCTION OF HIGH WATER-RETENTIVE PROTEOGLYCANS

摘要

PROBLEM TO BE SOLVED: To provide high water-retentive proteoglycans by improving the water retention of proteoglycans.SOLUTION: Proteoglycans as raw materials are treated with strong acidic cation exchange resins of alkali metal ion type such as sodium ion type or potassium ion type, or sodium and potassium ion mixture type.SELECTED DRAWING: Figure 2
