Dipropylene glycol is a member of the glycol compound class. In cosmetics, dipropylene glycol acts as a solvent, reducing viscosity, masking agent, and fragrance ingredient. As a solvent, dipropylene glycol helps to dissolve or suspend other ingredients in the formula without chemically changing other ingredients. Dipropylene glycol ensures an even distribution of all ingredients in a cosmetic formula and provides the appropriate consistency for the product. Dipropylene glycol also acts as a masking agent in cosmetics. A masking agent is used to mask the natural odor of active ingredients, especially those with an unpleasant odor. Sometimes, a masking agent can make a product so "clean" that consumers believe that the product has no odor.
