Description of key information

Based upon weight of evidence of important physico-chemical properties and available information. The water solubility of the chemical is reported to be 17.52 mg/L indicating slight water solubility which will ensure that the chemical shall be transferred by the blood to various parts of the body. The Log Kow value of the chemical is 1.4454 which according to the Lipinski rule shall ensure that the chemical shall be bio-available if ingested inside the human or animal body. The chemical has a Classification in the acute toxicity category 4 by the oral route of exposure. The chemical 3,7-bis(diethylamino)phenoxazin-5-ium acetate is used as an dyes. Thus, exposure by the oral route is unlikely but exposure by the dermal route is likely. The vapour pressures of the chemical suggest that toxicity by the inhalation route is also likely. The bio-concentration factor (BCF) of the chemical 3,7-bis(diethylamino)phenoxazin-5-ium acetate is reported to be 3.162 L/kg wet-wt(Predicted value) which suggest a low bio-accumulation potential (Bio-accumulation factor, BAF = 2.58 L/kg wet-wt). However, in the absence of any authoritative information pertaining to the absorption, distribution, metabolism and excretion of the chemical 3,7-bis(diethylamino)phenoxazin-5-ium acetate, bio-accumulation potential cannot be judged relying on certain physico-chemical properties and available information on BCF and BAF.
