Ammonium Chloride (CAS 12125-02-9) appears in 2 of the 2,122 car-care products CarCareTruth tracks (as of August 2026). It is readily biodegradable.

H302 (harmful if swallowed) and H319 (eye irritation) at undiluted ingredient strength. At 1–5% in cleaning formulas, the product-level effect is mild eye irritation only. Not a skin sensitizer.

Ammonium chloride is a common inorganic salt used as a mild buffering agent and surfactant booster in interior and leather cleaners. At ingredient strength it is classified Acute Tox. 4 (H302) and Eye Irrit. 2 (H319), but at consumer product concentrations of 1–5%, the working risk is limited to eye irritation from spray exposure.
