2-Ethylhexanol

  • Alcohol solvents
  • CAS 104-76-7
  • IUPAC: 2-ethylhexan-1-ol

2-Ethylhexanol (CAS 104-76-7) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026). It is classified as a VOC.

H315 (skin irritation Cat 2), H319 (eye irritation Cat 2), H332 (harmful if inhaled Cat 4), H335 (respiratory irritation STOT-SE Cat 3) at the substance level. ACGIH TLV 5 ppm TWA. At 1-5% in a diesel treatment mixture, these classifications may not propagate to the mixture level depending on the SDS classification methodology.

2-Ethylhexanol (2-ethylhexan-1-ol, CAS 104-76-7) is a branched-chain fatty alcohol used as a co-solvent and processing aid in fuel additive formulations. It is also a known decomposition product of 2-EHN (2-ethylhexyl nitrate) and may be present as both a formulation ingredient and a trace byproduct. At the substance level it carries H315 (skin irritation), H319 (eye irritation), H332 (harmful if inhaled), and H335 (respiratory irritation), though at typical fuel additive concentrations of 1-5% these classifications often do not propagate to the mixture-level SDS classification.
