Talc

  • Abrasives
  • CAS 14807-96-6
  • IUPAC: Magnesium silicate hydroxide

Talc (CAS 14807-96-6) appears in 2 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).

Industrial talc (not cosmetic-grade) may contain trace asbestos-form fibers depending on mineral source; ACGIH TLV 2 mg/m³ (respirable fraction). In liquid coatings, talc is suspended and does not create a respirable dust hazard during normal application. Not Prop 65–listed. IARC has classified some talc-based body powder containing asbestiform fibers as possibly carcinogenic (Group 2B) but this applies to specific mineral sources, not the talc used in automotive coatings.

Talc is a naturally occurring magnesium silicate mineral used as a filler and rheology modifier in automotive undercoatings and rubberized coatings. It contributes body and texture to the film and helps control sag resistance during overhead application. In liquid coatings formulations, the relevant health concern (respirable silicate dust) does not apply since the talc is suspended in the liquid matrix. The mineral is chemically inert under normal use conditions.
