Paraffin oils (petroleum), catalytic dewaxed light (CAS 64742-71-8) appears in 4 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).

Light mineral oil. Low acute toxicity. Not classified as a skin or respiratory irritant at typical product concentrations. IARC Group 3 (not classifiable as carcinogen) for the catalytic dewaxed/hydrotreated form.

Paraffin oils (petroleum), catalytic dewaxed light (CAS 64742-71-8) is a refined light mineral oil — a lower-viscosity counterpart to the catalytic dewaxed heavy fraction. It is produced by catalytic dewaxing of lighter petroleum distillate fractions.

This ingredient serves as a light-end viscosity modifier in lubricant blends, reducing the viscosity of the finished product to improve flow and spreading characteristics without compromising the protective film formed by heavier base oils. The hydrotreated form has low aromatic content and reduced carcinogen classification risk compared to conventional mineral oils.
