Description: Dimethyl isosorbide (DMI) is an additive in cosmetics and medications that can increase absorption into the tissue. When used in diluted form, it poses low risks to consumers. Higher concentrations can cause irritation, which may lead to inflammation, redness, and a stinging sensation. Pure dimethyl isosorbide tends to be stable and safe to work with as long as chemists use reasonable precautions, like facial protection to limit facial exposure from flashbacks.

This compound is a clear, slightly oily liquid. It can act as a solvent and carrier to combine with ingredients and facilitate their absorption. When products with dimethyl isosorbide are applied to the skin, it helps them penetrate instead of just depositing on the surface. It can also be added to dental care products like compounds to strengthen teeth or reduce sensitivity, ensuring that they have time to penetrate the tooth instead of being absorbed by the gums or accidentally swallowed.

Absorption is necessary with skin care products to prevent them from rubbing off and making a mess. In addition, it ensures deep, even coverage and provides more lasting treatment. Dimethyl isosorbide can be added to moisturizers, sunscreen, and anti-aging creams designed to penetrate the skin. Products with this additive shouldn’t leave a slick or greasy feeling once they finish saturating the skin, although it can take several minutes for them to fully soak in. During this period, the skin may need to be left exposed to avoid staining garments.
