Sweetened Middle Distillate (CAS 64741-86-2) appears in 1 of the 2,122 car-care products CarCareTruth tracks (as of August 2026). It is classified as a VOC.
GHS Carcinogenicity Category 1B (H350 — May cause cancer) per GHS US classification, attributed to polycyclic aromatic hydrocarbon (PAH) content in this petroleum fraction. Aspiration hazard if swallowed (H304). Classified as a suspected carcinogen from petroleum-distillate processing; the SDS separately notes that the product does not contain any California Prop 65 listed carcinogens.
Sweetened middle distillate (CAS 64741-86-2) is a petroleum refinery fraction produced by treating sulfur compounds in the middle distillate cut via the Merox process. The "sweetening" refers to converting mercaptans to disulfides, improving odor without hydrotreatment.
In fuel additive formulations, it serves as a carrier solvent and provides lubricity. The GHS Carcinogenicity Cat 1B classification arises from polycyclic aromatic hydrocarbons present in the petroleum fraction — a standard classification for petroleum middle distillates that have not been fully hydrotreated. The health concern is primarily occupational, from long-term repeated skin contact or vapor inhalation, not from brief consumer use.
This ingredient is distinct from hydrotreated middle distillates (CAS 64742-46-7), which have undergone more extensive processing to reduce PAH content.
