Amides, C8-18 (even) & C18-unsatd., N,N-bis(hydroxyethyl)

  • Nonionic surfactants
  • IUPAC: Amides, C8-18 (even numbered) and C18-unsaturated, N,N-bis(2-hydroxyethyl)

Amides, C8-18 (even) & C18-unsatd., N,N-bis(hydroxyethyl) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026). It is readily biodegradable.

Ingredient-level classification includes Skin Irrit. 2 and Eye Dam. 1 at undiluted concentration (per SDS). At product-use dilutions (0.1–0.5%), primary concern is skin contact during prolonged handling. Mixture-level risk for skin irritation is typically not classified at these concentrations.

A fatty acid amide mixture derived from C8–C18 even-chain and C18-unsaturated fatty acids reacted with diethanolamine. Used as a co-surfactant, foam stabilizer, and wetting agent in water-based cleaning formulations. At low concentrations (0.1–0.5%), this ingredient contributes to cleaning efficacy without significant health or environmental concern at use dilution.

Ingredient-level GHS classification reflects undiluted substance testing; mixture-level classifications at product concentrations are typically lower. Biodegrades aerobically. Low aquatic toxicity concern at product-use concentrations.
