  • CAS 64742-71-8

Paraffin Oils (Petroleum) (CAS 64742-71-8) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).

H350 (suspected carcinogen Cat 1B at ingredient level) — classification is driven by residual polycyclic aromatic hydrocarbon (PAH) content in certain highly refined petroleum mineral oils. Highly refined grades are tested to minimize PAH residues, but the GHS Cat 1B classification is maintained for untested or sub-threshold grades.

Paraffin Oils (CAS 64742-71-8) is a highly refined, heavy paraffinic mineral oil fraction used as a carrier and plasticizer in polymer-based coatings and restoration products. The H350 (suspected carcinogen Cat 1B) classification stems from polycyclic aromatic hydrocarbons (PAHs) that can persist in petroleum mineral oils below full-refinery treatment. At typical product concentrations (2.5–10%), the contribution to mixture-level carcinogenicity classification is significant. This ingredient is a key driver of the H350 classification in the Rust-Oleum Wipe New headlight restorer.
