Request SDS →PEG-150/Decyl Alcohol/SMDI Copolymer (CAS 193487-42-2) is a nonionic polyurethane copolymer supplied as a liquid rheology modifier. It is used to thicken and stabilize aqueous surfactant systems in personal-care and cleansing formulations.
Frequently Asked Questions
What is PEG-150/decyl alcohol/SMDI copolymer used for?
PEG-150/Decyl Alcohol/SMDI Copolymer (CAS 193487-42-2) is a nonionic polyurethane copolymer supplied as a liquid rheology modifier. It thickens and stabilizes aqueous surfactant systems, acting as an associative viscosity builder for cleansers and body washes.
How does PEG-150/decyl alcohol/SMDI copolymer thicken a formula?
It is an associative (hydrophobically modified) rheology modifier: its hydrophobic decyl/SMDI segments interact with surfactant micelles and oil phases to build a network that raises viscosity. This mechanism differs from electrolyte (salt) thickening and works well in surfactant-based cleansing systems.
What is SMDI in this copolymer?
SMDI refers to the saturated methylene diphenyl diisocyanate (hydrogenated MDI) used to link the PEG-150 and decyl-alcohol segments into a polyurethane copolymer backbone. The result is a nonionic associative thickener supplied as a liquid.
What is the CAS number and HS code for this copolymer?
It carries CAS 193487-42-2 and typically classifies under HS heading 3909.50 (polyurethanes in primary forms). Confirm the import classification for your jurisdiction with your broker.
How is bulk PEG-150/decyl alcohol/SMDI copolymer supplied, and how do I get a price?
