Use & Application
USP/EP grade isopropanol is used as pharmaceutical solvent and disinfectant raw material. It is applied for drug synthesis, topical antiseptic, extraction solvent and cleaning agent for pharmaceutical production equipment. It meets pharmacopoeia requirement for medical and drug formulation.
Cosmetic grade isopropanol works as solvent, viscosity reducer and astringent in skincare, hair care and perfume products. It helps dissolve fragrance and functional additives, provides quick-dry feeling in formulations such as toner, hair spray and makeup remover.
Industrial grade isopropanol serves as universal solvent for paints, coatings, inks and adhesives. It is widely used for electronic component cleaning, precision metal degreasing, extraction agent for fine chemicals, and antifreeze raw material. It is also common raw material for producing acetone and isopropyl esters.
