Dipropylene Glycol description

Dipropylene glycol is a synthetic slip agent, texturizer, and solvent, the latter a common use when combined with plant extracts, since it enhances their penetration into skin. It is a byproduct made in the production of propylene glycol. Its raw form is a colourless, odourless liquid. In cosmetics, it is used in concentrations as low as .004% to as high as 50% in some perfumes. The independent Cosmetic Ingredient Review panel has ruled dipropylene glycol is safe as used in cosmetics.
