Sodium Myristoyl Glutamate

Sodium myristoyl glutamate is a surfactant derived from glutamic acid, a naturally occurring amino acid, combined with myristic acid (a fatty acid). It functions as a mild cleanser in skincare formulations, helping to remove excess oil, makeup and surface impurities.Unlike harsher synthetic surfactants, this ingredient is designed to cleanse while maintaining the skin's natural barrier. It appears in a relatively small proportion of skincare products, typically in cleansers and micellar waters where its gentle action is valued.

As a surfactant, sodium myristoyl glutamate works by reducing the surface tension between oil and water, allowing oil-soluble impurities to be suspended and rinsed away. Its amino acid origin suggests it may interact more gently with skin proteins compared to conventional surfactants.The ingredient's structure — combining a hydrophilic (water-loving) head with a lipophilic (oil-loving) tail — enables it to sit at the boundary between oil and water, facilitating the removal of sebum and makeup whilst minimising disruption to the skin's protective layer.

This ingredient typically appears in cleansing products rather than leave-on treatments. Use as directed on the product label — usually as part of a water-based cleanser that is rinsed away. It can be incorporated into both morning and evening routines depending on the formulation and your skin's needs.

Sodium myristoyl glutamate is generally well-tolerated and considered mild. As with any cleansing ingredient, discontinue use if signs of irritation develop, particularly on sensitive or compromised skin.
