Stearic Acid

Home / Ingredient Glossary / Stearic Acid

Stearic acid is a non-essential fatty acid that can be synthesized by our bodies. It functions as an emollient to help prevent transepidermal water loss (TEWL) and supports healthy function of the skin barrier. It is often added to formulas to thicken and to help keep the oil and water components from separating.
