CarCareTruth tracks Aminosiloxane Polymer (CAS 68554-54-1) as a car-care ingredient.
Carries H315 (skin irritation Cat 2) and H319 (eye irritation Cat 2A) at ingredient level. Formulated at 1–3% in aqueous products, the mixture typically does not classify as hazardous. Direct contact with concentrated form warrants skin and eye caution.
Aminosiloxane polymer (CAS 68554-54-1) is the active SiO2 precursor used in water-based ceramic spray coatings. In finished product formulations, it appears at low concentrations (1–3%) in an aqueous carrier, where it provides the crosslinked silicone hydrophobic layer when applied to vehicle surfaces. The amino functional groups promote adhesion to paint, PPF, glass, and metal substrates.
At ingredient level, the substance is classified as Skin Irritant Cat 2 (H315) and Eye Irritant Cat 2A (H319) under GHS. These classifications typically do not propagate to the product mixture at the dilution levels found in consumer spray coatings, but warrant situational PPE (splash risk for eyes, prolonged contact for skin) in professional or concentrated-handling scenarios.
