Trichloroacetic acid: General information, toxicity, formulations, and histology

HALOACETIC ACIDS Haloacetic acids are derivatives of acetic acid in which one or more hydrogen atoms on the alpha carbon1 are replaced by halogens (fluorine, chlorine, bromine, or iodine) (Figure 12.1). The haloacetic acid most commonly used in peels is trichloroacetic acid, and we will therefore look at the chlorine derivatives of acetic acid.
