Dimethyl Isosorbide

Dimethyl Isosorbide is a bio-based solvent derived from renewable plant sugars (typically corn glucose) that has become highly valued in modern cosmetic formulations for its exceptional ability to enhance the penetration and efficacy of active ingredients without irritation. Unlike traditional solvents, it offers a unique dual functionality: it dissolves both hydrophilic and lipophilic actives while simultaneously improving their delivery into skin, making it particularly popular in high-performance serums containing retinoids, peptides, and antioxidants. Formulators choose it for its elegant skin feel, lack of tackiness, and ability to boost active ingredient performance at concentrations of 1-10%.
