Dolomite

  • Abrasives
  • CAS 16389-88-1
  • IUPAC: Calcium magnesium carbonate

Dolomite (CAS 16389-88-1) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).

Dolomite used as a coatings filler is not classified as a GHS health hazard in liquid formulations. Not Prop 65–listed. The mineral is chemically inert at the concentrations used in consumer putties. Crystalline silica content in dolomite is typically very low — verify source-specific SDS for respirable crystalline silica if processing in powder form, but this concern does not apply to liquid coatings.

Dolomite is a naturally occurring calcium magnesium carbonate mineral (CaMg(CO₃)₂) used as an inert filler in automotive putties and body repair compounds. At concentrations below 3% in liquid formulations, dolomite contributes minor body and viscosity modification without significant health or environmental impact. The mineral is chemically stable, not classified as a GHS hazard in liquid coatings, and not listed under California Proposition 65.
