Sodium Polyglutamate is a cutting-edge cosmetic ingredient celebrated for its exceptional moisturizing and skin-smoothing properties. Chemically, it is derived from polyglutamic acid, a natural peptide found in fermented soybeans. In cosmetics, Sodium Polyglutamate often appears as a white to off-white powder or a clear, slightly viscous liquid, depending on its form. This ingredient works by binding moisture to the skin, enhancing hydration and promoting a smoother, plumper complexion. Further, Sodium Polyglutamate is commonly used in high-end skincare products due to its superior moisture retention abilities.
Origin
Sodium Polyglutamate is typically produced through a fermentation process using microorganisms like Bacillus subtilis. During fermentation, polyglutamic acid is synthesized from glutamic acid, and then sodium ions are added to form the sodium salt. The resulting compound is then purified and processed into various forms, such as powders or liquids, for use in cosmetics.
Safety profile
Sodium Polyglutamate is safe for topical use on skin and hair. It is not known to be toxic or pose significant health risks when used as directed. However, in case of known allergies or sensitivities, a patch test must be performed.
