ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms.
NOTES
The EU classification refers to a group of substances known as quaternary ammonium compounds, benzyl C8-18-alkyldimethyl chlorides. Benzalkonium
chloride itself is a mixture of very similar substances with different chain length and molecular mass. Other CAS RNs: 8001-54-5 XXXX Other UN and
Transport Emergency Card numbers are possible, depending on manufacturers1classifications.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and
medical observation is therefore essential.
This substance is usually commercially available as a solution. Strong solutions (>10%) are corrosive.
