High purity polyglutamic acid (cosmetic grade) high moisturizing biopolymer
Polyglutamic Acid (INCI: POLYGLUTAMIC ACID) / Fermentation-derived high molecular weight moisturizing ingredient
Next-generation high-moisturizing ingredient that complements hyaluronic acid. A fermentation-derived polymer that excels in moisture retention and lasting hydration.
Polyglutamic Acid is a high molecular weight amino acid polymer obtained through microbial fermentation, characterized by its high moisturizing properties and the ability to form a supple film, making it an excellent cosmetic ingredient. Its amino acid-derived hydrophilicity allows it to retain moisture effectively, supporting the hydration of the skin's surface. When used in conjunction with hyaluronic acid, it enables richer texture design and is widely adopted in formulations aimed at enhancing moisturizing power. This product is a highly transparent water-soluble ingredient that can accommodate a wide range of types from low to high viscosity, making it suitable for various categories such as serums, lotions, emulsions, and gel creams. It has properties that leave a soft finish on the skin, providing a moist after-feel while minimizing stickiness, which has been highly praised by cosmetic manufacturers both domestically and internationally. It maintains stable quality and high purity unique to fermentation, making it suitable for products that appeal to clean beauty. It does not compromise formulation transparency and has almost no scent, allowing it to be used in concept lines for sensitive skin or minimal formulations. Its versatility as a moisturizing ingredient is extremely high, making it a valuable raw material for diverse product development.
