Sodium Glutamate

What is Sodium Glutamate?

Sodium Glutamate is the sodium salt of L-glutamic acid, a non-essential amino acid present in many proteins and produced via fermentation processes. In cosmetics, it belongs to the humectant and conditioning agent category, commonly found in skincare creams, lotions, shampoos, and conditioners. It works by attracting and retaining moisture to hydrate skin and hair shafts, improving texture and flexibility. As a conditioning agent, it coats surfaces to reduce friction, static, and tangles, promoting smoothness. Additionally, it neutralizes off-odors and stabilizes fragrance notes, refining the sensory profile of formulations. Its water-soluble nature allows easy incorporation into aqueous-based products, supporting mild, everyday use without disrupting skin's natural balance.
