Secondary Alcohol Ethoxylate

  • Nonionic surfactants
  • CAS 84133-50-6
  • IUPAC: Alcohols, C11-14-iso-, C13-rich, ethoxylated

Secondary Alcohol Ethoxylate (CAS 84133-50-6) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026). It is readily biodegradable.

Low mammalian toxicity. May cause mild skin and eye irritation at concentrate concentrations. At product use dilutions, health hazard is minimal. No respiratory sensitizer or carcinogen classification.

Secondary alcohol ethoxylates (SAE) are nonionic surfactants made from branched C11-C14 alcohols that are ethylene oxide-condensed. They function as wetting agents and emulsifiers in aqueous formulas. In leather care sprays they help disperse the conditioning oils and silicones into the water phase.

The branched structure makes them more readily biodegradable than their linear counterparts but also gives them moderate aquatic toxicity at higher concentrations. In finished products at typical 0.1-2% concentrations, risk to aquatic environments is low when properly disposed of.
