1139 SODIUM TRICHLOROACETATE
IMPORTANT DATA
Physical State; Appearance Routes of exposure
HYGROSCOPIC WHITE TO YELLOW POWDER The substance can be absorbed into the body by inhalation of
its aerosol.
Chemical dangers
Inhalation risk
Reacts with strong bases producing chloroform - see ICSC
0027. A nuisance-causing concentration of airborne particles can be
reached quickly on spraying.
Occupational exposure limits
Effects of short-term exposure
TLV not established.
The substance is irritating to the eyes, the skin and the
respiratory tract.
PHYSICAL PROPERTIES
Decomposes below melting point at 165掳C Solubility in water, g/100 ml at 25掳C: 120 (very good)
Relative density (water = 1): 0.9 Octanol/water partition coefficient as log Pow: 0.002
ENVIRONMENTAL DATA
The substance is 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.
TCA is also the abbreviation for trichloroacetic acid (ICSC 0586) in some countries.
