Nonane

  • Aliphatic solvents
  • CAS 111-84-2
  • IUPAC: Nonane

Nonane (CAS 111-84-2) appears in 2 of the 1,812 car-care products CarCareTruth tracks (as of June 2026). It is classified as a VOC.

Aliphatic C9 hydrocarbon. OSHA TSCA §12(b) export notification substance. H304 aspiration hazard at ingredient level — standard for C7–C10 aliphatic hydrocarbons. CNS depression effects at high vapor concentration. Not classified as a carcinogen or reproductive toxin. Not a Prop 65 substance.

Nonane (CAS 111-84-2) is a straight-chain C9 alkane naturally present in petroleum fractions and used as a wicking co-solvent in penetrating-oil and cleaner formulations. Its low molecular weight and low surface tension contribute to capillary penetration into corroded fastener threads alongside the primary petroleum-distillate carrier.

At trace concentrations (0.1–1.5% in CRC Screwloose 03060), nonane is a minor formula component. Its significance for environmental scoring is its log Kow of 5.65 — above the bioaccumulation threshold (log Kow ≥ 5.0) used in the penetrating-oil environment rubric, contributing to the bioaccumulative-ingredient deduction alongside the light petroleum distillate carrier fraction.

Nonane is a US TSCA §12(b) export notification substance and appears in some regulatory chemical inventories. It is not listed under California Proposition 65.
