Isopropyl Stearate is an ester of isopropyl alcohol and stearic acid that used as binder, emollient, and moisturizer in the pharmaceutical and cosmetic industries. Stearate esters act primarily as lubricants on the skin's surface, which gives the skin a soft and smooth appearance. Isopropyl Stearate has the unique properties of low viscosity and oily nature, which results in a nongreasy, hydrophobic film when applied to the skin or lips. Undiluted Isopropyl Stearate was classified as a slight ocular irritant.
