Description
Glutamic Acid (CAS 56-86-0) is a naturally occurring amino acid commercially available under names including Glusate, Aciglut, and GLUTACID, and abbreviated as GLU or L-Glu. It carries no E-number designation. It is produced via fermentation and is the free acid form of glutamate, distinct from its sodium salt.
In personal care formulations, Glutamic Acid functions as a pH buffer and skin conditioner by donating or accepting protons within the physiological range, stabilising emulsion systems without aggressive acidification. In food and pharmaceutical applications, it acts as a humectant and antioxidant, binding water molecules and slowing oxidative degradation in sensitive matrices.
Glutamic Acid is sourced in food-grade (FCC-compliant) and pharmaceutical-grade (Ph.Eur.) specifications, with REACH registration covering supply within the EU. It is available as a white crystalline powder in standard packaging from 25 kg bags to bulk quantities. Procurement teams should confirm grade suitability against application-specific regulatory requirements.
