Frequently Asked Questions

What is PEG/PPG-14/4 dimethicone used for?

PEG/PPG-14/4 dimethicone (CAS 68937-55-3) is a water-dispersible silicone polyether (dimethicone copolyol) supplied as a nonionic surfactant. It functions as a silicone emulsifier for oil-in-water systems and as a wetting agent that lowers interfacial tension in aqueous personal-care and industrial formulations.

What is a dimethicone copolyol?

A dimethicone copolyol is a silicone backbone grafted with polyethylene-glycol and/or polypropylene-glycol chains, giving it both silicone and water-compatible character. The PEG/PPG-14/4 designation indicates roughly 14 ethylene-oxide and 4 propylene-oxide units, which set its water dispersibility and surface activity.

Is PEG/PPG-14/4 dimethicone water soluble?

It is described as water-dispersible rather than freely water-soluble; the polyether grafts allow it to disperse and emulsify in aqueous systems. Exact dispersion behavior depends on formulation pH, electrolytes, and temperature.

What is the CAS number and HS code for PEG/PPG-14/4 dimethicone?

It carries CAS 68937-55-3 and typically classifies under HS heading 3910.00 (silicones in primary forms). Confirm the import classification for your jurisdiction with your broker.
