Quaternium-80
- Cationic surfactants
- CAS 134737-05-6
- IUPAC: Quaternium-80
Quaternium-80 (CAS 134737-05-6) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).
No GHS classification at consumer product use concentrations. Functions as an anti-static agent and surface protectant; the quaternary ammonium structure provides the charge-dissipating anti-static mechanism. Not classified as a skin sensitizer or respiratory hazard at mixture-level concentrations typical of interior cleaner formulas.
Quaternium-80 is a silicone quaternary ammonium compound (silicone quat) used as a surface modifier, conditioner, and anti-static agent in personal care and household/automotive cleaning products. Unlike cyclic silicones (D4/D5), Quaternium-80 has a different structure and regulatory profile. It functions by depositing a thin polymer-like layer on treated surfaces that dissipates electrostatic charge, reducing the attraction of airborne dust particles — the mechanism behind the anti-static dust repellency claims in interior detailer products.
In automotive interior care formulations, it serves a dual role: surface protection (the "cross-linking polymer" that cures to the surface) and anti-static dust repellency. At the concentration levels typical of ready-to-use interior cleaners, it presents no GHS hazard classification.
