Request SDS →PEG/PPG-20/20 Dimethicone (CAS 68937-54-2) is a silicone polyether (dimethicone copolyol) supplied as a nonionic surfactant. In its silicone-surfactant class it serves as an emulsifier and wetting agent for personal-care and industrial formulations.
Frequently Asked Questions
What is PEG/PPG-20/20 dimethicone used for?
PEG/PPG-20/20 dimethicone (CAS 68937-54-2) is a silicone polyether (dimethicone copolyol) supplied as a nonionic surfactant. It serves as a silicone emulsifier for oil-in-water systems and as a wetting agent that lowers interfacial tension in personal-care and industrial formulations.
What does the 20/20 designation mean in PEG/PPG-20/20 dimethicone?
The 20/20 indicates approximately 20 ethylene-oxide (PEG) and 20 propylene-oxide (PPG) units grafted onto the dimethicone backbone. This ratio sets the balance between water and oil compatibility and the material's emulsifying behavior.
Is PEG/PPG-20/20 dimethicone the same as PEG/PPG-14/4 dimethicone?
No. Both are dimethicone copolyols but they differ in the number of ethylene-oxide and propylene-oxide units, which changes their HLB, water dispersibility, and emulsification performance. They are distinct grades with different CAS numbers (68937-54-2 vs 68937-55-3).
What is the CAS number and HS code for PEG/PPG-20/20 dimethicone?
It carries CAS 68937-54-2 and typically classifies under HS heading 3910.00 (silicones in primary forms). Verify the tariff line for your destination with your customs broker.
