The draft Toxicological Review of trichloroacetic acid provides scientific support and rationale for the hazard and dose-response assessment pertaining to chronic exposure to trichloroacetic acid. Trichloroacetic acid is used as an antiseptic, skin peeling agent, and chemical intermediate to produce a variety of organic chemicals. Trichloroacetic acid is also used industrially as an etching and pickling agent for surface treatment of metals and as a solvent in the plastics industry. Trichloroacetic acid is formed from organic materials during water chlorination. This assessment contains the derivation of a chronic reference dose and cancer oral slope factor.
