International Chemical Safety Cards TRICLOPYR-2-BUTOXYETHYLESTER ICSC: 0963 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: BROWN OILY LIQUID PHYSICAL DANGERS: As a result of flow, agitation, etc., electrostatic charges can be generated. CHEMICAL DANGERS: The substance decomposes on heating producing toxic and corrosive fumes . OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by ingestion. INHALATION RISK: No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is mildly irritating to the eyes . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. PHYSICAL PROPERTIES Boiling point: 370°C Relative density (water = 1): 1.3 Solubility in water, g/100 ml: (none) Octanol/water partition coefficient as log Pow: 4.3 ENVIRONMENTAL DATA This substance may be hazardous in the environment; special attention should be given 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. N O T E S The substance is combustible but no flash point is available in literature. Carrier solvents used in commercial formulations may change physical and toxicological properties. Garlon, Turflon are trade names. ADDITIONAL INFORMATION ICSC: 0963 TRICLOPYR-2-BUTOXYETHYLESTER (C) IPCS, CEC, 1994
