What is Dipropylene Glycol?
Dipropylene glycol is a form of alcohol that is added to skincare products and cosmetics to help improve the texture and stability of the formula. Mainly used as a solvent or a viscosity decreasing agent, it may also be added as a fragrance ingredient to certain types of products. It is a member of compounds belonging to the glycol class, which is a term for organic compounds that belong to the alcohol family. Sometimes this ingredient may also be used as a plasticizer and intermediate in industrial chemical reactions. It has a high boiling point, no odor, and low toxicity.
Dipropylene glycol acts as a solvent that helps to dissolve or suspend ingredients in a formula without altering the other ingredients. It also helps provide even distribution of ingredients in cosmetics to help with even application and consistency. You'll often find it in makeup products like CC creams or foundations. It also helps to thin out formulas and helps improve viscosity to improve the texture of a product. This makes it an ideal addition to skin and hair care products. Dipropylene glycol also works as a masking agent in cosmetics and personal care products to help disguise the natural smell of active ingredients.
