CARBENDAZIM ICSC: 1277
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS OR GREY TO WHITE POWDER.

CHEMICAL DANGERS:
The substance decomposes slowly on contact with bases.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: Germ cell mutagen group: 3A; (DFG 2005).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Animal tests show that this substance possibly causes toxicity to human reproduction or development.
PHYSICAL PROPERTIES
Melting point (decomposes): 302-307C
Density: 0.27 g/cm
Solubility in water, g/100 ml at 24C: 0.0008
Vapour pressure, Pa at 20C: negligible
Octanol/water partition coefficient as log Pow: 1.49
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal.
NOTES
If the substance is formulated with solvents also consult the ICSCs of these materials. Carrier solvents used in commercial formulations may change physical and toxicological properties.
