IMPORTANT DATA
Physical State; Appearance HYGROSCOPIC WHITE TO YELLOW POWDER Chemical dangers Reacts with strong bases producing 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, the skin and the respiratory tract.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Decomposes below melting point at 165°C Relative density (water = 1): 0.9 Solubility in water, g/100 ml 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 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.
