What is Sorbitan Stearate?

Sorbitan Stearate is a non-ionic emulsifier created by combining sorbitol, a sugar alcohol sourced from corn or fruits, with stearic acid, a saturated fatty acid from plant oils like palm or coconut. Commonly used in skincare formulations such as moisturizers, foundations, and cleansers, it functions by lowering the surface tension at the oil-water interface. This action forms a protective film that prevents phase separation, ensuring products maintain a uniform, creamy consistency over time. Its surfactant properties also aid in dispersing ingredients evenly and providing a subtle foaming or dispersing effect in rinse-off products. Overall, it contributes to the sensory appeal and stability of emulsions without dominating the formula.
