Propylene Glycol, USP Propylene Glycol, is a nearly odorless clear liquid with a mild sweet taste. In the skin and hair, propylene glycol works as a humescent, which causes retention of moisture content of skin or cosmetic products by preventing the escape of moisture or water.

Propylene Glycol USP is the most common moisture-carrying vehicle, other than water itself, in cosmetics. Absorbs moisture, acts as a solvent and a wetting ingredient.
