  • Applications

    Di-O-benzoyldiethylene glycol (CAS number: 120-55-8) is commonly used as a plasticizer for polymer and resin systems, improving flexibility in coatings, adhesives, sealants, and PVC formulations. It also serves as a solvent or processing aid in coatings, inks, and cleaning formulations, leveraging its polar character and moderate volatility. As an organic synthesis intermediate, it is often used to prepare other benzoate esters and related specialty chemicals. In fragrance and cosmetic applications, it can function as a solvent or carrier for fragrance ingredients, and may be used as a solvent component in cosmetic formulations under applicable regulations. It is also encountered as a processing solvent/diluent in household cleaning products.
