International Chemical Safety Cards TRIBENURON-METHYL ICSC: 1359 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: BROWN SOLID IN VARIOUS FORMS PHYSICAL DANGERS: CHEMICAL DANGERS: 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 when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. PHYSICAL PROPERTIES Melting point: 141°C Relative density (water = 1): 1.5 Solubility in water: good Octanol/water partition coefficient as log Pow: -0.44 ENVIRONMENTAL DATA Avoid release to the environment in circumstances different to normal use. N O T E S 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. ADDITIONAL INFORMATION ICSC: 1359 TRIBENURON-METHYL (C) IPCS, CEC, 1994
