Frequently Asked Questions
What is Quaternary-80 Blend used for?
Quaternary-80 Blend (CAS 68439-46-3) is a C9-C11 alcohol ethoxylate nonionic surfactant used as a detergent surfactant in household and industrial cleaning concentrates, a wetting agent, an emulsifier for oil-in-water systems, and a dispersant for suspending solids in liquid systems.
What is Quaternary-80 Blend made from?
It is produced by ethoxylating C9-C11 fatty alcohols, giving an alcohol ethoxylate of the type widely used as a general-purpose wetting, emulsifying, and detergent surfactant. Despite the name, it is a nonionic ethoxylate supplied under CAS 68439-46-3.
Is Quaternary-80 Blend a wetting agent or an emulsifier?
Both. As an alcohol ethoxylate it lowers surface tension for uniform substrate coverage (wetting) and also stabilizes oil-in-water systems in processing and formulation (emulsifying), and it functions as a dispersant. The intended role depends on dose and the rest of the formulation.
What CAS number and HS code apply to Quaternary-80 Blend?
It is supplied under CAS 68439-46-3 and classified under HS heading 3402.42 (nonionic organic surface-active agents). Confirm the final import classification with your customs broker for your destination country.
What is the cost of bulk Quaternary-80 Blend and how is it packaged?
Pricing depends on volume and market conditions, so we quote per order rather than publish a fixed price. Request a bulk RFQ with your required quantity for pack sizes, MOQ, lead time, and a CoA/SDS.
What is the REACH and TSCA regulatory status of Alcohols, C9-11 Ethoxylated (C9-11 Pareth, Fatty Alcohol Ethoxylate)?
Alcohols, C9-11 Ethoxylated (C9-11 Pareth, Fatty Alcohol Ethoxylate) (CAS 68439-46-3) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 614-482-0).
