Dipropylene Glycol Dibenzoate

An oily liquid that makes your skin nice and smooth (aka emollient). It is also claimed to have some humectant and moisturizing properties without a greasy after-feel. But its real superpower is being an outstanding solvent for hard to solubilize sunscreen agents (that is most of the chemical sunscreen filters) making it an excellent emollient choice in high SPF products.
