Solvent, Penetration Enhancer

Dimethyl Isosorbide

Dimethyl Isosorbide (DMI) is a bicyclic ether derived from isosorbide, itself a renewable sugar-based (sorbitol/glucose) compound. In cosmetic formulations it functions primarily as a high-purity solvent and skin penetration enhancer, capable of dissolving a wide range of active ingredients and helping them to penetrate more deeply into the skin. Because it can carry actives through the stratum corneum, it is particularly valued in formulations targeting anti-acne, skin-brightening, and self-tanning results.
