Overview

EPA has finalized the Toxicological Review of Trichloroacetic Acid: in support of the Integrated Risk Information System (IRIS). Now final, this assessment may be used by EPA’s program and regional offices to inform decisions to protect human health.

Background

The Toxicological Review of Trichloroacetic Acid provides scientific support and rationale for the hazard identification 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.
