N O T E S

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 manufacturers'classifications. 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.
Transport Emergency Card: TEC (R)-61GTC2-II
