CHLOROBENZILATE ICSC: 0749
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS OR PALE YELLOW CRYSTALS.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic and corrosive fumes. Reacts with strong acids, bases and strong oxidants, causing fire hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established. MAK not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and by ingestion.

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the skin. The substance may cause effects on the central nervous system, resulting in impaired functions.

PHYSICAL PROPERTIES
Melting point: 37C
Density: 1.28 g/cm^3
Solubility in water: very poor
Vapour pressure, Pa at 20C: negligible
Flash point: see Notes
Octanol/water partition coefficient as log Pow: 4.74
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish. 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
The substance is combustible but no flash point is available in literature. Carrier solvents used in commercial formulations may change physical and toxicological properties. Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
