Dimethyl Isosorbide (DMI) is a high purity solvent and carrier which offers a safe, effective delivery enhancement mechanism for active ingredients in personal care products. Sunless tanners, facial and eye-zone treatments, skin serums, anti-acne formulations and make-up removers are just some of the products whose performance can be improved with the use of Dimethyl Isosorbide in formulation. In addition to improving performance, its use as an epidermal penetration enhancer can allow formulators to reduce the amount of actives required to achieve effects, resulting in reduced formulation costs, and lower skin irritation with aggressive active ingredients.
