Inhalation of dry powder dust at industrial volumes can cause pneumoconiosis (kaolinosis) — not a hazard in formulated liquid car-care products where the clay is dispersed in a fluid matrix.

Calcined kaolin is a heat-treated aluminum silicate clay. In cleaner-waxes it provides the very fine mineral abrasive that removes light oxidation and contamination without the aggression of cutting compounds.
