Carbon Black
- Dyes & colorants
- CAS 1333-86-4
- IUPAC: Carbon (amorphous)
Carbon Black (CAS 1333-86-4) appears in 7 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).
IARC Group 2B (possibly carcinogenic) classification based on occupational inhalation exposure to carbon black dust at high concentrations. In liquid paint formulations, carbon black is suspended and does not present a respirable dust hazard. No Prop 65 listing at consumer product concentrations. SDS OEL OSHA PEL 3.5 mg/m³ (as nuisance dust); ACGIH TLV 3.0 mg/m³ inhalable fraction. Primary concern is dusty application scenarios (powder pigment handling), not liquid paint use.
Carbon black is the standard black pigment in automotive paints, lacquers, inks, and plastics. It is produced by incomplete combustion of heavy petroleum products. At the particle sizes and concentrations used in liquid touch-up paints, the IARC 2B classification (based on occupational inhalation of dry carbon black dust) is not directly applicable to consumer paint application scenarios. Carbon black provides the deep, opaque black color in universal black automotive touch-up products.

They describe the ingredient itself; whether a hazard applies to a finished product depends on its concentration and how it's used.
