Glutamic Acid
What is Glutamic Acid?
Glutamic acid is a non-essential amino acid, chemically 2-aminopentanedioic acid, abundant in nature within proteins like gluten and gelatin, and produced via fermentation or extraction from plant sources. In cosmetics, it features prominently in hair conditioners, shampoos, and moisturizers. It functions as a humectant by drawing atmospheric moisture to skin and hair surfaces, enhancing hydration levels. Its structure enables bonding with keratin proteins, smoothing cuticles for improved hair texture and reduced static charge. It also stabilizes product pH as a buffer and imparts a mild scent. Valued for compatibility in both rinse-off and leave-on formulas, it supports overall product performance without heaviness.
