Isopropyl myristate (IPM) is an ester of isopropyl alcohol and myristic acid widely used in cosmetics and topical formulations as an emollient, solvent, and penetration enhancer that improves skin feel and spreadability. It is considered a base/formulation ingredient rather than a therapeutic active.
