Description

Sodium Polyglutamate is a biodegradable, water-soluble polymer derived from glutamic acid, a naturally occurring amino acid. This versatile compound is valued for its exceptional moisture-retention, film-forming, and chelating properties, making it a high-performance ingredient for demanding formulations. It is essential for manufacturers in the cosmetics, personal care, food, and agricultural industries seeking natural, multifunctional, and environmentally friendly additives.

Application

• Cosmetics & Personal Care: Acts as a highly effective humectant and moisturizer in creams, lotions, serums, and hair care products, improving skin feel and hydration.
• Food Industry: Functions as a flavor enhancer (umami), thickener, and stabilizer in various food products, leveraging its natural origin and safety profile.
• Agriculture: Used as a biodegradable chelating agent in fertilizers and plant growth promoters to enhance nutrient absorption and soil conditioning.
• Pharmaceuticals: Employed as an excipient in drug delivery systems for its biocompatibility and ability to modify drug release profiles.
• Industrial Applications: Serves as a dispersant, scale inhibitor, and biodegradable additive in water treatment and textile processing.
