Sodium Myristoyl Glutamate

What is Sodium Myristoyl Glutamate?

Sodium Myristoyl Glutamate is an anionic surfactant synthesized from glutamic acid, an amino acid naturally found in proteins, and myristic acid, a saturated fatty acid often sourced from coconut or palm kernel oil. It belongs to the acyl glutamate family, prized in cosmetics for its biodegradable and skin-friendly profile. Primarily used in rinse-off products like facial cleansers, body washes, shampoos, and baby formulations, it functions by reducing surface tension between water, oils, and dirt. This enables effective micelle formation, where impurities are encapsulated and easily rinsed away without stripping the skin's natural moisture barrier. Its mild nature stems from its amphoteric-like behavior despite being anionic, providing rich foam and emulsification while minimizing disruption to the skin's pH and lipid layer. Often featured in 'sulfate-free' or natural-leaning products for daily use.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Surfactant
Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.
Cleansing agent
Removes dirt, oil, and impurities by lowering surface tension and forming micelles, enabling soils to be lifted and rinsed away from skin, hair, or teeth.

Benefits

Delivers gentle yet effective cleansing without harshness.

Supports mild foaming and emulsification in washes.

Compatible with sensitive skin formulations due to low irritation potential.
