About this ingredient

Stearic acid is a naturally occurring saturated fatty acid derived from animal or vegetable sources that functions as a versatile texturizer and stabilizer in cosmetic formulations. In creams, lotions, and sunscreens, it acts as an emulsifier and thickener to create smooth, stable products while providing emollient and mild skin-conditioning benefits that support the skin barrier.
