ESFENVALERATE ICSC: 1516
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO WHITE CRYSTALS.

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

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 SHORT-TERM EXPOSURE:
The substance is mildly irritating to the eyes, is irritating to the skin and the respiratory tract. The substance may cause effects on the nervous system.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization.
PHYSICAL PROPERTIES
Melting point: 59-60C
Density: 1.2 g/cm
Solubility in water: none
Vapour pressure, Pa at 20C: negligible
Flash point: 256C
Octanol/water partition coefficient as log Pow: 6.2
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
Carrier solvents used in commercial formulations may change physical and toxicological properties. If the substance is formulated with solvents also consult the ICSCs of these materials. Do NOT take working clothes home. The technical product is a brown to yellow liquid, with a melting point between 43-54C and a boiling point between 151-167C. See ICSC 0273 Fenvalerate.
Card has been partly updated in April 2005. See section EU classification.
