What Is Dimethyl Isosorbide?
Dimethyl isosorbide is a clear, slightly oily-feeling liquid that functions as a solvent. It may be plant-based or synthetic. This ingredient is also used to decrease the thickness of products, such as keeping a liquid in its fluid form rather than letting it revert to a lotion (or, in cosmetics chemistry parlance, an emulsion with higher viscosity).
Another desirable function of dimethyl isosorbide is to allow controlled, sustained delivery of key ingredients such as antioxidants, so they can, in theory, provide stronger and longer-lasting benefits.
Use levels of dimethyl isosorbide in cosmetics range from 1–10% depending on desired aesthetics and which ingredients, if any, may need help penetrating past skins’ surface and doing so in a more controlled manner to reduce risk of irritation. It’s considered non-irritating to skin and eyes.
