Key value for chemical safety assessment

Additional information

In Annex IX of Regulation (EC) No 1907/2006, it is laid down that chronic toxicity tests shall be proposed by the registrant if the chemical safety assessment indicates the need to investigate further the effects on fish. According to Annex I of this regulation, the chemical safety assessment triggers further action when the substance or the preparation meets the criteria for classification as dangerous according to Directive 67/548/EEC or Directive 1999/45/EC or is assessed to be a PBT or vPvB. The hazard assessment of AH-salt reveals neither a need to classify the substance as dangerous to the environment, nor is it a PBT or vPvB substance, nor are there any further indications that the substance may be hazardous to the environment. In Particular, AH salt does not appear as harmful to fish in acute toxicity test. Furthermore, chronic toxicity tests of the hydrolysis products Adipic acid (CAS: 124-04-9) and Hexamethylendiamine (CAS: 124-09-4) towards Daphnia magna revealed no observed effect concentrations (NOECreproduction) of 6.3 and 4.2 mg/l, respectively and by thereby clearly underlining the little hazard potential of AH-salt (MOE 1997, 2002). Therefore, and for reasons of animal welfare, a long-term toxicity study on fish is not provided.
