Solvents are liquids employed to dissolve components found useful in cosmetics or drugs. Water is the most common solvent found in cosmetics. Nonaqueous solvents are required in a variety of cosmetics, such as colognes, hair sprays, and nail lacquers. Specific solvent capabilities of certain cosmetic ingredients can be used, e.g., to remove sebum from the skin, to loosen make-up, to extract essential oils, or to dissolve dyes. |
