Dipropylene Glycol Methyl Ether is a colorless liquid with a mild and pleasant odor. It is a solvent used in paints, pastes, dyes, resins, brake fluids and inks, and in making cosmetics. 
DPM is similar in its properties to DPG ( Di-propylene Glycol) and is often used as alternative to DPG due to its milder odor and lower potential for skin irritation. Like DPG , DPM has good solubility properties and can effectively dissolve a wide range of fragrance oils
DPM is an important ingredient in most perfumes and fragrances. Dipropylene Glycol's role in perfume is that it binds and carries the essential oils of the fragrance element of a perfume. It not only acts to bind and carry, but also acts as a diluter to help determine the strength of the fragrance oils.
