Sodium Lauroyl Glutamate description

Sodium lauroyl glutamate (SLG) is a mild cleansing agent often used in rinse-off skin care products. SLG’s the salt form of the combination of amino acid glutamic acid and lauric acid, a fatty acid commonly sourced from coconut oil. As a surfactant, SLG helps cleanse skin, which is why it’s commonly included in face washes and cleansers. Because of the amino and fatty acids present in SLG, it’s often referred to as a great option for sensitive skin. It imparts a smooth and soft feeling after use. The Cosmetic Ingredient Review Expert Panel reviewed SLG and deemed it safe for use in cosmetics. It can appear in cosmetics and hair care in amounts ranging from 0.003% all the way to 40%. In its raw material state, SLG appears as a white or pale-yellow powder.
