PYRIPROXYFEN ICSC: 1269
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic fumes including nitrogen oxides, carbon monoxide.

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

INHALATION RISK:
Evaporation at 20°C 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:
The substance may have effects on the blood and liver, resulting in anaemia, impaired functions and tissue lesions.
PHYSICAL PROPERTIES
Melting point: 45-47°C
Relative density (water = 1): 1.2
Solubility in water: none (<0.1g/100ml)
Vapour pressure, Pa at 20°C: 0.0003
 		Octanol/water partition coefficient as log Pow: 5.37
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. In the food chain important to humans, bioaccumulation takes place, specifically in aquatic organisms. The substance may cause long-term effects in the aquatic environment. Avoid release to the environment in circumstances different to normal use.
NOTES
If the substance is formulated with solvent(s) also consult the card(s) (ICSC) of the solvent(s). Carrier solvents used in commercial formulations may change physical and toxicological properties. Sumilarv is a trade name.
