Titanium Tetraisopropanolate

  • Ceramic (SiO₂)
  • CAS 546-68-9
  • IUPAC: tetrakis(propan-2-yloxy)titanium

Titanium Tetraisopropanolate (CAS 546-68-9) appears in 3 of the 2,122 car-care products CarCareTruth tracks (as of August 2026).

Reacts vigorously with water and protic solvents. Causes skin and eye irritation (H315/H319) and releases isopropanol on hydrolysis. Not classified as a carcinogen, reproductive toxicant, respiratory sensitizer, or Prop 65 substance. At 1–3% in a petroleum-naphtha-based ceramic coating, the primary hazard pathway is the carrier solvent rather than the titanate itself. No OSHA PEL established; handle with chemical-resistant gloves.

Titanium tetraisopropanolate (TTIP, CAS 546-68-9) is an organotitanium alkoxide used as a crosslinker in some ceramic coating formulations, including CarPro Cquartz UK 3.0. It is moisture-sensitive: exposure to atmospheric humidity triggers hydrolysis to titanium dioxide (TiO₂) and isopropanol, forming the hard inorganic oxide network that contributes to the coating's scratch and chemical resistance.

Health: Irritant to skin and eyes via direct contact. Releases isopropanol on hydrolysis — a mild CNS narcotic at high concentrations but well below hazard thresholds at trace product levels. Not a sensitizer, carcinogen, or reproductive toxicant. The primary health hazard in products containing TTIP comes from the petroleum-naphtha carrier solvent rather than the titanate component itself.

Environment: Low concern at in-use concentrations. The hydrolysis product TiO₂ is the active that cures to form the coating surface; it is chemically inert and non-aquatically toxic. TTIP itself is not listed under any environmental priority-chemical frameworks.
