UNISURF L30 (SODIUM LAURYL SARCOSINATE 30%)
General Overview
UNISURF L30 is a versatile and mild anionic surfactant based on Sodium Lauroyl Sarcosinate, offering excellent foaming, wetting, and cleansing properties with a low irritation profile. Derived from lauric acid and sarcosine (an amino acid derivative), it is ideal for personal care applications such as shampoos, facial cleansers, and oral care products. Its compatibility with other surfactants makes it a valuable component in sulfate-free and sensitive-skin formulations.
