  • Applications

    Chemical name: 1-Propanol, 2-methoxy-, 1-acetate; CAS number: 70657-70-4. This glycol ether acetate is used primarily as a solvent and dispersing medium in a range of industrial formulations, notably coatings, inks, and adhesives. It also serves as a solvent or co-solvent in cleaning formulations and household products, and can function in cosmetics and personal care products as a solvent or formulation aid. In fragrance applications, it may act as a solvent or fixative for certain fragrance compositions. In polymers and plastics, it can act as a plasticizer or processing aid, and in industrial manufacturing it can serve as a processing solvent or intermediate in organic synthesis.
