International Chemical Safety Cards TRINEXAPAC-ETHYL ICSC: 1268 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE POWDER. 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: A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Melting point: 36°C Relative density (water = 1): 1.3 Solubility in water, g/100 ml at 20°C: 0.28-2.11 (pH-dependant) Vapour pressure, Pa at 20°C: 0.003 Flash point: 133°C Auto-ignition temperature: 355°C Octanol/water partition coefficient as log Pow: 2.44 (pH-dependant) ENVIRONMENTAL DATA The substance is harmful to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to algae, water plants and soil organisms. Avoid release to the environment in circumstances different to normal use. N O T E S Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. 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. The technical product is a yellow-brown liquid. Moddus, Primo, Vision are trade names. ADDITIONAL INFORMATION ICSC: 1268 TRINEXAPAC-ETHYL (C) IPCS, CEC, 1994
