Request SDS →Bis-PEG/PPG-20/20 dimethicone (CAS 151662-01-0) is a silicone polyether — a dimethicone backbone modified with polyethylene-glycol and polypropylene-glycol chains. As a silicone-based nonionic surfactant, it is used to emulsify and stabilize silicone and oil phases in personal-care formulations.
Frequently Asked Questions
What is Bis-PEG/PPG-20/20 dimethicone used for?
Bis-PEG/PPG-20/20 dimethicone (CAS 151662-01-0) is a silicone polyether — a dimethicone backbone modified with polyethylene-glycol and polypropylene-glycol chains. As a silicone-based nonionic surfactant it emulsifies and stabilizes silicone and oil phases in personal-care formulations.
Is Bis-PEG/PPG-20/20 dimethicone the same as amodimethicone?
No. This material is a PEG/PPG-modified silicone polyether used as a nonionic emulsifier (CAS 151662-01-0), whereas amodimethicone is an amino-functional silicone. They are chemically distinct and serve different formulation roles.
How does Bis-PEG/PPG-20/20 dimethicone function as an emulsifier?
Its silicone backbone is lipophilic while the PEG and PPG side chains are hydrophilic, giving the molecule surface activity. This lets it stabilize water-silicone and water-oil systems and act as a wetting aid in personal-care formulations.
What is the CAS number for this silicone polyether?
It is CAS 151662-01-0, an INCI Bis-PEG/PPG-20/20 dimethicone. As a defined silicone-polyether copolymer it is identified by its CAS and INCI name; confirm the assigned HS classification for your destination on the quote.
How is this silicone emulsifier supplied in bulk and can you provide a CoA and SDS?
