  • Applications

    Propylene glycol di(2-methylbutyrate) (CAS 155514-30-0) is a diester of propylene glycol with 2-methylbutyric acid and is typically used as a plasticizer for polymers and coatings, improving the flexibility and processability of materials. It also functions as a solvent and processing aid in coatings, inks, and adhesives. In cosmetics and personal care, it can act as an emollient and co-solvent in formulations. As an intermediate in the synthesis of specialty esters and fragrance components, it is often used in chemical manufacturing workflows. Its applications depend on formulation, polymer choice, and local regulatory restrictions.
