"On the Differences between Propylene Glycol and Glycolic Acid"

Fupropanediol and glycolic acid, although both are chemical substances, their properties are different.

Propylene glycol is a colorless and clear viscous liquid with a slightly sweet taste and hygroscopicity. It is mostly used as a solvent and moisturizer, and is involved in the pharmaceutical, food, and cosmetic industries. For example, when making pharmaceuticals, it can be used as a solvent to assist in the dissolution of drugs; when making cosmetics, it can keep the skin moist.

Glycolic acid is a colorless and easily hydrolyzed crystal. It is active and highly acidic. It is often a raw material for chemical synthesis. In skin care products, it is also commonly used because it can exfoliate and refresh the skin.

Compared with the two, propylene glycol is mild in nature and strong in glycolic acid. In terms of use, propylene glycol has tremendous support for moisture and dissolution; glycolic acid exfoliates and synthesizes raw materials. Although they belong to the same chemical category, they each perform their own duties and have different interests.
