Fatty Alcohol Ethoxylate (2-Propyl, 7 EO)

  • Nonionic surfactants
  • CAS 160875-66-1
  • IUPAC: 1-heptanol, 2-propyl, 7 EO

Fatty Alcohol Ethoxylate (2-Propyl, 7 EO) (CAS 160875-66-1) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026). It is readily biodegradable.

At 1–5% concentration in a product formula, no systemic hazard classification. Eye irritant at high concentrations; may contribute to skin sensitization potential in concentrated aqueous product. Not Prop 65-listed. No asthmagen or respiratory sensitizer classification.

1-Heptanol, 2-propyl, 7 EO (CAS 160875-66-1) is a branched fatty alcohol ethoxylate surfactant used as a wetting agent in aqueous coating maintenance formulations. The 7-EO (ethylene oxide) chain provides good water dispersibility and film uniformity during spray application.

Health: Low systemic hazard at normal formulation concentrations (1–5%). Eye and skin irritation are the relevant exposure pathways at concentrate strength; at working-solution concentrations, irritation potential is minimal. Not classified as a sensitizer at mixture level by ECHA, though nonionic ethoxylates can contribute to the overall sensitization burden in multi-sensitizer formulations.

Environment: Aquatically toxic at ingredient level — nonionic ethoxylates of this type typically exhibit Aquatic Acute 1 and Aquatic Chronic 3 GHS classification. Biodegrades under aerobic conditions. No bioaccumulation concern owing to the relatively short carbon chain.
