Halogenated Polyaromatics
White to light tan or pink solid; [Hawley]
Used in household, hospital, and veterinary disinfectants; Also used as a fungicide, herbicide, antimicrobial, and cosmetics preservative; [HSDB] Used as a disinfectant (swimming pool decks, industrial water systems, poultry houses and other farming premises, food processing, and restaurants); [Reference #1]
Emergency medical treatment: see phenol and related agents; A skin irritant; One of the chemicals that can cause toxic vitiligo; [HSDB] Chemical leukoderma is indistinguishable from vitiligo; May occur in workers exposed to hydroquinones, catechols, phenols, or mercaptoamines; [White, p. 285] A mutagen, tumorigen, and mild skin irritant; Causes somnolence and convulsions in lethal-dose studies of mice; [RTECS] A skin, mucous membrane, and respiratory tract irritant; Corrosive to eyes; "It has also caused severe porphyria cutanea tarda." [CAMEO] Chemical associated with acquired porphyria include hexachlorobenzene, 2,4-dichlorophenol, 2,4,5-trichlorophenol, 2,3,7,8-tetrachlorodibenzo-p-dioxin, o-benzyl-p-chlorophenol, 2-benzyl-p-dichlorophenol, vinyl chloride, lead, and aluminum; However, recent studies have failed to find an association between 2,3,7,8-tetrachlorodibenzo-p-dioxin and porphyrin levels; [LaDou, p. 266, 519] Corrosive to eyes; Causes kidney injury in chronic animal experiments and is a possible human carcinogen; [Reference #1] An irritant; Effects in high-dose animal studies include convulsions; [MSDSonline]
