Use of a non-phosphate detergent builder, alanine, N,N-bis(carboxymethyl)-trisodium salt (ABCT), has been expanded to wide range of washing and cleaning products for consumer uses and industrial applications including cleaning agents in food or pharmaceutical factories. Therefore, determination of acceptable daily exposure (ADE) of ABCT by oral, parenteral or inhalation route based on updated toxicity database could provide valuable information on the risk management for protection of consumers, patients and workers. Here, we proposed the ADEs based on the toxicological information of various in vivo and in vitro non-human studies. Because the full report of each toxicity study was not disclosed, derivation of the ADE was done based on available information mainly from ECHA database. ABCT exhibited renal toxicity as a main effect; however, ABCT did not exhibit carcinogenicity, genotoxicity, reproductive toxicity, irritation, and sensitization. Applying modification factors to the NOAEL of the animal study of longest treatment period, oral ADE was determined as 260 mg/person/day. Taking the oral bioavailability into the consideration of conversion to other routes, parenteral and inhalation ADEs were determined as 50 mg/person/day.
