  • Applications

    Di-tert-butyl decanedioate (CAS 143050-66-2) is a diester of sebacic acid with tert-butyl groups, providing thermal stability and high molecular weight characteristics. In practice, it is used primarily as a plasticizer for polymers such as PVC, polyurethanes, and coatings, and it also serves as a processing solvent or processing aid for coatings, inks, and adhesives. In cosmetics and personal care, it may be used as a solvent or emulsifying/compatibility agent in formulations; in fragrance applications, it may function as a solvent or fragrance fixative in formulation. Additionally, it may be employed as an intermediate in the synthesis of specialty polymers or as a component in plasticizer systems for plastics and elastomers. Use is subject to local regulations and formulation limits.
