- CAS 64742-56-9
Distillates (petroleum), solvent-dewaxed light paraffinic (CAS 64742-56-9) appears in 1 of the 2,179 car-care products CarCareTruth tracks (as of August 2026).
A lighter paraffinic distillate fraction than the heavy paraffinic distillates used alongside it. The Ergon HyGold P71N SDS built on this same CAS classifies the finished product 'Not classified' for physical, health, and environmental hazards, with serious eye damage/irritation 'Not classified (may cause minor irritation),' skin sensitization 'Not classified,' and no aspiration-hazard classification confirmed via IP 346 testing. That SDS also carries an affirmative state-regulatory statement that the product is not known to contain any Prop 65-listed carcinogens or reproductive toxins.
A severely-refined light paraffinic petroleum distillate fraction (CAS 64742-56-9) used as a minor base-oil component in finished lubricant blends, contributing lower-viscosity flow characteristics than the heavy paraffinic fractions it is typically blended with. Produced by solvent-dewaxing a petroleum distillate cut to remove normal paraffins, yielding a finished oil with viscosity below roughly 19 cSt at 40°C.
At the severe refining level used in modern base-oil production (confirmed via IP 346 DMSO-extract testing below the 3% carcinogen-exemption threshold), this fraction is not classified as a carcinogen, mutagen, or skin/eye hazard. A third-party SDS built primarily on this CAS number (Ergon HyGold P71N) reports the finished product as "Not classified" across physical, health, and environmental hazard categories, with an affirmative negative Prop 65 statement. This differs from the "untreated or mildly treated" mineral oil class that carries a California Prop 65 listing; severe hydroprocessing and solvent dewaxing removes the substance from that class.
