What Is Sorbitan Stearate?
Sorbitan stearate is primarily used as an emulsifier to enhance the texture of skin care and makeup products. It helps thicken and stabilize the formulation and may also act as a dispersing agent.
Sorbitan stearate is derived from a type of sugar known as sorbitol + the gentle fatty acid stearic acid. As a raw material, it is light cream to tan in color and can take the form of beads, flakes, or a hard waxy solid.
In 2019, the Cosmetic Ingredient Review (CIR) Expert Panel re-reviewed sorbitan stearate and deemed it safe in cosmetic use (their report looked at products containing up to 5%). That same report mentions 8% is permitted in topically applied drugs.
Sorbitan stearate does have the ability to impart fragrance but only if used in high concentration (closer to the 5% end of spectrum).
