Propylene Glycol is a synthetic liquid substance that absorbs water. It's widely used in cosmetics and personal care products as a moisturizer to maintain the soft and smooth appearance of the skin. Because of its ability to absorb water, it helps keep products from drying out. It's also used as a carrier for fragrance oils, enhancing the absorption of other ingredients into the skin.
In perfumes, Propylene Glycol serves as a solvent, carrier, and sometimes as a fixative. It is used to dissolve fragrance oils and ensure that the scent is evenly distributed throughout the product, enhancing the stability and longevity of the fragrance. Propylene Glycol's effectiveness as a solvent helps in blending the perfume's components smoothly, making it a valuable ingredient in fragrance formulations.
