Sodium Stearoyl Lactylate

Overview

Sodium stearoyl lactylate is an anionic surfactant, which means it is a negatively charged molecule that features both a water-loving head group and an oil-loving tail.

This ingredient is used as an emulsifier, which means it blends oils with water to form a stable product, like a lotion or a cream. Specifically, sodium stearoyl lactylate forms oil-in-water emulsions.

It can also serve as a cleansing agent, and although anionic surfactants are typically irritating on their own, sodium stearoyl lactylate is uncharacteristically gentle on skin. However, it will still be found blended with other types of surfactants.
