Distillates (petroleum), hydrotreated light

  • Aliphatic solvents
  • CAS 64742-47-8

Distillates (petroleum), hydrotreated light (CAS 64742-47-8) appears in 7 of the 2,122 car-care products CarCareTruth tracks (as of August 2026). It is classified as a VOC.

Aspiration hazard Cat 1 (H304) at the substance level — may be fatal if swallowed and liquid enters airways. Skin-irritant/defatting with repeated contact. Hydrotreating reduces aromatic and sulfur content relative to straight-run distillates, lowering carcinogen concern, but it remains a volatile petroleum solvent.

Distillates (petroleum), hydrotreated light (CAS 64742-47-8) is a refined petroleum-distillate fraction produced by hydrotreating a light distillate cut to remove sulfur and reduce aromatic content. It is widely used as a carrier solvent in fuel additives, penetrating oils, and cleaning concentrates.

Hydrotreating lowers the aromatic and sulfur burden compared with straight-run or catalytically cracked distillates, which reduces the carcinogen and odor profile. The fraction remains a volatile hydrocarbon solvent (a VOC) and carries an aspiration hazard (H304) at the substance level because its kinematic viscosity falls below the CLP exemption threshold — a swallowing hazard rather than an inhalation one.

In aquatic terms this cut is not benign: measured toxicity data place it in the "toxic to aquatic life with long-lasting effects" range (LL50 in the single-digit mg/L for fish), and it is not readily biodegradable, so it counts as a persistent, aquatic-toxic petroleum solvent in environmental scoring.
