A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Trideceth-10 (CAS 78330-21-9) is a nonionic surfactant formed by ethoxylating tridecyl alcohol with an average of ten ethylene-oxide units. As an ethoxylated-alcohol surfactant it functions as an emulsifier, wetting agent, and solubilizer in detergent, household, and industrial cleaning systems. The degree of ethoxylation sets its hydrophile-lipophile balance, making it a co-surfactant in aqueous formulations.

Frequently Asked Questions
What is another name for polyoxyethylene 10 tridecyl ether?
It is commonly known as Trideceth-10 (CAS 78330-21-9). It is an ethoxylated-alcohol nonionic surfactant made by reacting tridecyl alcohol with an average of ten ethylene-oxide units.
What is polyoxyethylene ether?
A polyoxyethylene (ethoxylated) ether is a nonionic surfactant formed by adding ethylene-oxide units to a fatty alcohol. In Trideceth-10 the average of ten ethylene-oxide units sets the hydrophile-lipophile balance, giving its emulsifying and wetting behavior.
What is polyoxyethylene 10 tridecyl ether used for?
It acts as a nonionic emulsifier for oil-in-water systems, a wetting agent for soil and surface wetting in industrial and household cleaners, and a solubilizer that couples water-insoluble actives and fragrances into aqueous bases. It is typically used as a co-surfactant in aqueous formulations.
What is the HS code for Trideceth-10?
It classifies under HS 3402.42 (non-ionic organic surface-active agents). Confirm the destination tariff line and documentation requirements with our team before export.
What is the price of bulk polyoxyethylene 10 tridecyl ether, and how is it packaged?
Pricing varies with volume and packaging; we do not list a fixed catalog price. Request a bulk quote with your target volume and drum/tote/IBC preference, and we will confirm availability along with the CoA and SDS.
What is the REACH and TSCA regulatory status of Trideceth-10 (Polyoxyethylene 10 Tridecyl Ether)?
Trideceth-10 (Polyoxyethylene 10 Tridecyl Ether) (CAS 78330-21-9) is listed as Active on the U.S. EPA TSCA Inventory; its REACH registration status is not determined from the public ECHA registry.
