Benzalkonium Chloride
كلوريد البنزالكونيوم
Quaternary ammonium disinfectant (quat) · CAS: 8001-54-5
Common disinfectant - fine on surfaces; ventilate sprays (asthma link).
Why this verdict
GHS-hazardous (corrosive/irritant/oxidiser) but a legitimate cleaning active - handle with care.
What It Is
A 'quat' disinfectant found in many wipes and antibacterial sprays.
The disinfectant in most antibacterial wipes and sprays. Effective at use-dilution, but it's a concentrate that's corrosive and toxic to aquatic life - and repeated spray exposure is linked to occupational asthma. Reasonable for surfaces; ventilate, and don't drench yourself daily.
