Dimethyl Isosorbide
What is Dimethyl Isosorbide?
Dimethyl Isosorbide, often abbreviated as DMI, is a synthetic, colorless liquid produced by methylating isosorbide, a diol derived from the dehydration of sorbitol sourced from natural carbohydrates. In cosmetics, it serves as a solvent for hydrophilic ingredients like peptides, vitamins, and humectants, and as a penetration enhancer in categories such as serums, gels, and anti-aging creams. It works by dissolving polar compounds and temporarily disrupting the skin's lipid barrier to allow deeper delivery of actives, without leaving residue. Its low viscosity and compatibility with aqueous systems also aid in stabilizing formulations, preventing separation and ensuring consistent texture. This makes it valuable in lightweight, fast-absorbing products designed for targeted application.
