PHYSICAL STATE; APPEARANCE:
ODOURLESS WHITE OR COLOURLESS CRYSTALS.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on burning producing toxic and corrosive fumes of nitrogen oxides and chlorine (see ICSC 0126). Solutions are corrosive to aluminum, iron and tin.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body through the skin and by ingestion.

INHALATION RISK:
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Melting point: 151-152°C
Solubility in water, g/100 ml at 20°C: poor
Vapour pressure, Pa at 25°C: 0.002

ENVIRONMENTAL
DATA

Avoid release to the environment in circumstances different to normal use.

N O T E S

Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. Lontrel and Matrigon are trade names.
