PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
HYGROSCOPIC WHITE-TO-YELLOW POWDER WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic and corrosive fumes including ammonia, chlorine and nitrogen oxides. 

Formula: C6H5CH2N(CH3)2RCl, R=C8H17 - C18H37

Melting point: 29-34°C
Solubility in water at 20°C: good 


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body through the skin and by ingestion. 

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. If a solution is swallowed, aspiration into the lungs may result in chemical pneumonitis. 

Inhalation risk
 

Effects of long-term or repeated exposure
 


Occupational exposure limits
 

ENVIRONMENT
The substance is very toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment. 

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 RN: 8001-54-5; Other UN 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.
