Dimethyl Isosorbide description

Dimethyl isosorbide is a clear, slighlty oily-feeling liquid that functions as a solvent and may be plant-based or synthetic. It is also used to decrease the thickness of products, such as keeping a liquid in its fluid form rather than wllowing it to rever to a lotion (or, in cosmetics chemistry parlance, a thicker emulsion). Another function of this ingredient is to allow controlled, sustained delivery of key ingredients such as antioxidants, so they can, in theory, provide stronger benefits.
