HYGROSCOPIC WHITE-TO-YELLOW POWDER. 

Physical dangers
 

Chemical dangers
Reacts with strong bases. This produces chloroform (see ICSC 0027). 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol. 

Inhalation risk
A nuisance-causing concentration of airborne particles can be reached quickly on spraying. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 165°C
Relative density (water = 1): 0.9
Solubility in water, g/100ml at 25°C: 120 (very good)
Octanol/water partition coefficient as log Pow: 0.002  
The substance is toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example 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.
