Light Aromatic Hydrocarbons (Solvent Naphtha, Light Aromatic)
- Aromatic solvents
- CAS 64742-47-8
- IUPAC: Naphtha, petroleum, light aromatic
Light Aromatic Hydrocarbons (Solvent Naphtha, Light Aromatic) (CAS 64742-47-8) appears in 3 of the 1,812 car-care products CarCareTruth tracks (as of June 2026). It is classified as a VOC.
VOC-contributing aromatic petroleum fraction. Skin defatting with prolonged contact. No confirmed systemic health hazard at mixture concentrations. Drives high-VOC classification when present at 5–10%.
Light aromatic hydrocarbons (CAS 64742-47-8) is a petroleum-derived solvent fraction used as a carrier in car care polishes and compounds. It dissolves and disperses abrasive particles and oils evenly across surfaces, improving spreadability and workability.
The aromatic fraction contributes significantly to VOC content — products containing 5–10% can push VOC readings well above 250 g/L, triggering high-VOC health_bar flags. No systemic health hazard at mixture concentrations typical in consumer polishes, but skin defatting from prolonged or repeated direct contact is possible; gloves are appropriate for extended use.
Environmentally, the compound is not aquatically toxic at product dilutions and is not persistent in the same way as PFAS, though it is a VOC and contributes to ground-level ozone.
