What is Polyethylene glycol dimethyl ether?
Polyethylene glycol dimethyl ether (CAS 24991-55-7), abbreviated PEGDME and known commercially as Selexol, is a series of end-capped polyethylene glycol oligomers.
Where is Polyethylene glycol dimethyl ether used?
- Industrial gas treatment: active solvent in physical absorption processes removing CO2, H2S and other acid gases from natural gas and syngas streams
- Personal care: humectant and emollient carrier in skin creams, hair conditioners and leave-on treatments
- Polymer processing: plasticizer improving flexibility and workability in PVC compounds and adhesive formulations
- Cleaning and industrial solvents dissolve a broad range of soils.
Commercial specifications
- Commercial grades range from PEGDME 250 to PEGDME 2000, reflecting average molecular weight
