C.I. Solvent Black 29

  • Dyes & colorants
  • CAS 117527-94-3
  • IUPAC: Solvent Black 29

C.I. Solvent Black 29 (CAS 117527-94-3) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).

GHS classification: combustible dust (OSHA003). No health H-codes at typical use concentrations in formulated products. No skin irritation, sensitization, or respiratory codes for this ingredient at 1–5% in linseed-oil matrix.

C.I. Solvent Black 29 (CAS 117527-94-3) is a solvent-soluble black dye used in penetrating trim restorers to supplement or replace the natural darkening provided by linseed oil oxidation. In Adam's Black Trim Restorer, it appears at 1–5% in a ≥80% boiled linseed oil matrix, providing color depth and a more uniformly black result than linseed oil alone would produce on heavily faded plastic.

Aquatic hazard: SDS Section 12 for the formulated product classifies C.I. Solvent Black 29 as "harmful to aquatic life with long lasting effects" — LC50 112 mg/L in fish over 96 hours. Chronic EC50 is >1,000 mg/L in aquatic invertebrates. The stay-on-car application pattern (trim restorer is not rinsed off) limits direct waterway exposure during use, but wash runoff over subsequent vehicle washes does carry trace amounts.

Environmental note: No PBT or vPvB classification — the persistence concern is mild compared to silicone-based or fluoropolymer ingredients. Biodegradation data are not available.

Health and environment notes translate the manufacturer Safety Data Sheet, the GHS classification, and authoritative regulatory listings (California Prop 65, EPA). Not medical advice. They describe the ingredient itself; whether a hazard applies to a finished product depends on its concentration and how it's used.
