Frequently Asked Questions
What is Trideceth-9?
Trideceth-9 (CAS 24938-91-8, C15H32O2 nominal) is the polyethylene-glycol ether of tridecyl (C13) alcohol with an average of 9 ethylene-oxide units. It is a nonionic surfactant and emulsifier used in cleaning and personal-care formulations.
What is Trideceth-9 used for?
It is used as a nonionic surfactant and wetting agent, an oil-in-water emulsifier, a solubilizer in cosmetic formulations, and a surfactant component in detergents and cleaners.
What is the difference between Trideceth-9 and Trideceth-10?
Both are ethoxylated tridecyl alcohols; the number is the average count of ethylene-oxide units (9 versus 10). The higher ethoxylate is slightly more hydrophilic, which shifts HLB and emulsification behavior in a formulation.
Is Trideceth-9 ionic or nonionic?
Trideceth-9 is a nonionic surfactant, carrying no net ionic charge. This gives it broad compatibility with anionic, cationic, and other surfactants in formulated cleaning and personal-care products.
