Hydroxystearic Acid description

Hydroxystearic acid is a fatty acid-based ingredient that has much versatility. It can work in cleansing formulas as a surfactant while adding emollient and texture-enhancing properties to products such as moisturisers, makeup, and sunscreens. The natural form derived from castor oil is used most, but hydroxystearic acid can also be made synthetically. It is chemically similar to stearic acid, another fatty acid used in thousands of skin care, makeup, and hair care products since it is non-irritating and works well in many types of formulas. Emerging research from a supplier of an oleic acid-derived form of hydroxystearic acid shows it may play a role in reducing pore size and fading discolourations; however, independent research is needed to verify such claims. Research from Unilever shows it works to help offset hyperpigmentation triggered by exposure to airborne pollutants, possibly due to its antioxidant ability which prevented the oxidation of lipids (fats) in skin that would normally occur when exposed to such pollutants. Hydroxystearic acid is considered safe as used in cosmetics at concentrations of 10% or less. The typical usage level for this ingredient is 1-5%.
