- Aliphatic solvents
- CAS 108-87-2
- IUPAC: Methylcyclohexane
Methylcyclohexane (CAS 108-87-2) appears in 2 of the 1,812 car-care products CarCareTruth tracks (as of June 2026). It is classified as a VOC.
Mild CNS depressant at high vapor concentrations. Highly flammable (flash point −4°C). Less hazardous than hexane or heptane — no reproductive toxicity classification. ACGIH TLV-TWA: 400 ppm. Use with adequate ventilation.
Methylcyclohexane is a cycloaliphatic solvent (C7) common in petroleum distillate and naphtha-based aerosol formulas. It has moderate evaporation rate and low residue. Flash point −4°C makes it flammable. Mild CNS depressant at high inhalation concentrations; no chronic toxicity or reproductive concerns at typical use levels.
