Isopropyl Alcohol

Isopropyl Alcohol (IPA) is a three-carbon alcohol produced primarily through the hydration of propylene, a petroleum derivative. Formulators value it as a fast-evaporating solvent that enhances ingredient penetration, reduces viscosity in formulations, and provides quick-drying properties in products like toners, astringents, and hand sanitizers. Its antimicrobial properties at concentrations above 60% make it particularly useful for preservation and sanitization, though its drying nature limits use in leave-on moisturizing products.
