CarCareTruth tracks Silica, Mica (CAS 12001-26-2) as a car-care ingredient.
Mica (phyllosilicate mineral) used as inert filler. Respirable mica dust has established OEL (TWA 3 mg/m³ respirable). Not classified as a carcinogen in standard form; not an asthmagen.
Silica, Mica (CAS 12001-26-2) is a group of layered silicate minerals used as inert fillers and thickeners in paste formulations including anti-seize compounds, brake lubricants, and electrical joint compounds. The mica platelet structure provides body and consistency to the paste carrier while remaining chemically inert across a wide temperature range.
The primary health concern is respirable dust exposure in occupational settings; at product-use concentrations in a paste format (bound in grease carrier), the respirable dust pathway is negligible. Standard occupational exposure limits (OEL) apply for handling the dry mineral in manufacturing contexts.
