What is Dimethyl sebacate?
Dimethyl sebacate (CAS 106-79-6), also known as DMS, is a dibasic ester derived from sebacic acid. Also marketed as dimethyl decanedioate.
Where is Dimethyl sebacate used?
- Plastics and polymer processing: plasticizer for PVC, cellulosics and synthetic resins, improving flexibility and processing characteristics in films and coatings
- Lubricants: base fluid or co-fluid in synthetic lubricants and metalworking fluids
- Personal care: emollient and skin-conditioning agent in creams, serums and color cosmetics
- At flavor-grade purity it contributes fruity and fatty notes to food and beverage formulations.
Good to know: Low volatility and thermal stability suit demanding formulation and processing environments; oxidative stability at elevated temperatures is a requirement for industrial lubricant use.
Commercial specifications
- Clear, low-viscosity liquid in drum and IBC quantities
- Technical and high-purity grades; food- and flavor-grade material for regulated applications
- Specifications typically aligned with FCC purity benchmarks
