What is Diethylhexyl sebacate?
Diethylhexyl sebacate (CAS 122-62-3), abbreviated DOS and also sold as bis(2-ethylhexyl) sebacate, is a long-chain diester plasticizer and lubricant base fluid.
Where is Diethylhexyl sebacate used?
- PVC and synthetic rubber: cold-flexibility plasticizer for wire insulation, automotive seals and refrigeration gaskets
- Industrial lubricants: synthetic base fluid in compressor oils, greases and hydraulic fluids
- Personal care: emollient and skin-conditioning agent in creams, sunscreens and color cosmetics
- Food-contact packaging uses approved grades as a plasticizer in films and gasket materials.
