Halogenated Phenol

4-Chlororesorcinol is a halogenated phenol that is used as a hair colorant in over 30 hair dye and color products, generally at concentrations <1% Hair dye and color products containing 4-Chlororesorcinol will generally have a warning statement and patch test instructions for determining if each individual user is sensitive to the product before use. The available data do not suggest that 4-Chlororesorcinol is particularly toxic. The oral median lethal dose in rats was 369 mg/kg. Subchronic dermal exposure of rats to a hair dye product containing 2% 4-Chlororesorcinol produced no evidence of compound-induced toxicity. At that same dermal exposure, no embryotoxic or teratogenic effects, no evidence of reproductive toxicity, and no carcinogenic effects were seen. Likewise, 4-Chlororesorcinol was not mutagenic in either a micronucleus or Ames test, not did it induce aneuploidy in neurospora. A 2.5% solution was not a dermal irritant or an ocular irritant in rabbits. While there was some concern that impurity data were not available, the use of actual formulations in the reproductive toxicity and carcinogenicity studies failed to produce any evidence of toxicity. On the basis of the information in the report, it was concluded that 4-Chlororesorcinol is safe as currently used in hair dye formulations.

Anaerobic Dehalogenation

Levels of total organic hallde (TOX) in a Kraft mill wastewater ranged from 26,000 to 60,000 µg/l. An aerated stabilization basin (ASB) proved capable of removing one-third to one-half of both the total TOX as well as lower molecular weight (&lt;l,000) TOX. Influent. TOX levels varied as a function of in-mill production activities. Removal of specific size fractions of of organic halide were influenced to different extents by influent variations and seasonal effects. The major removal mechanism appears to be biosorption of TOX onto settling biomass, followed by anaerobic dehalogenation within the benthal layer of the ASB.
