Product Description

Sodium Lauroyl Sarcosinate is a mild anionic surfactant derived from sarcosine and lauric acid. It is widely used in personal care, cosmetics, oral care, and cleansing formulations due to its excellent foaming, cleansing, emulsifying, and conditioning properties.

Compared with traditional sulfate-based surfactants, Sodium Lauroyl Sarcosinate provides a gentler cleansing effect with lower irritation potential, making it particularly suitable for sensitive skin and premium personal care products.

It also offers good compatibility with various surfactants and active ingredients, making it highly versatile in modern formulation systems.
