Lubricating oils (petroleum), C15-30, hydrotreated neutral oil-based

  • Aliphatic solvents
  • CAS 72623-86-0

Lubricating oils (petroleum), C15-30, hydrotreated neutral oil-based (CAS 72623-86-0) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).

H304 (aspiration hazard Cat 1) present at ingredient level. At the mixture level in Petro-Canada SDS for ACDelco Dexron-VI ATF (GHS 2.0, rev 2015-01-26), the mixture is classified as NOT hazardous — no mixture-level H-codes. Kinematic viscosity at 40°C ~29.8 mm²/s (from SDS §9), above the 20.5 mm²/s CLP exemption threshold — H304 is waived from mixture-level classification. No skin, eye, or respiratory irritation classification at mixture level. California Prop 65 cancer warning appears on bottle; the listed substance is attributed to this petroleum base stock.

A REACH-registered Group III hydrotreated petroleum base stock (CAS 72623-86-0) with a C15-30 carbon chain range. Produced by severe hydrotreatment of neutral petroleum fractions to reduce aromatic content. Used as the primary base oil in ATF formulations, motor oils, and gear lubricants marketed as "full synthetic" under the API Group III synthetic definition.

The ingredient carries H304 (aspiration hazard Cat 1) at the ingredient level. However, at the high kinematic viscosity typical of this material (~29.8 mm²/s at 40°C for ATF base stocks), the CLP regulation's viscosity exemption waives H304 from the mixture-level GHS classification — meaning finished ATF formulations using this base stock at >20.5 mm²/s KV40 typically classify the mixture as NOT hazardous in SDS §2. California Prop 65 warnings on products containing this substance reflect petroleum-derived mineral oil mist carcinogenicity under state law.
