Organo moly-sulfur complex (molybdenum dithiocarbamate-type friction modifier) (CAS 1928735-59-4) appears in 1 of the 2,179 car-care products CarCareTruth tracks (as of August 2026).

Disclosed in the finished motor oil's SDS §3 at 0.1-0.3% by weight. The finished product's SDS §2 classifies the mixture as 'Not classified' with no signal word and no mixture-level H-codes, and §11 confirms no expected skin sensitization, mutagenicity, or carcinogenicity for the mixture. No ingredient-level H-code was disclosed for this specific substance in the sourcing SDS.

An organomolybdenum-sulfur friction-modifier additive (CAS 1928735-59-4) belonging to the same general dithiocarbamate/dithiophosphate complex family as other molybdenum-based anti-friction additives used in full-synthetic motor oils, disclosed in the sourcing SDS at 0.1-0.3% by weight. These additives work by depositing a low-friction molybdenum disulfide layer on metal surfaces under boundary-lubrication conditions, reducing friction and wear independent of, or alongside, traditional zinc-based anti-wear chemistry.

No substance-specific regulatory dossier (ECHA, PubChem) was located for this exact CAS registration at the time of research; the finished product's own SDS discloses it only as a named component at a trade-secret-protected concentration range, with no ingredient-level hazard statement. Health and environmental defaults here follow the established molybdenum friction-modifier class by structural analogy, consistent with the low disclosed concentration.
