Description of key information

The chemical safety assessment carried out according to Annex I of Regulation (EC) No 1907/2006 does not indicate the need to investigate further the long-term toxicity to fish.

Key value for chemical safety assessment

Additional information

There are no long-term fish studies available for the LCAE category members. The chemical safety assessment according to Annex I of Regulation (EC) No 1907/2006 does not indicate the need to investigate further the long-term toxicity to fish. Thus, in accordance to Annex IX, column 2 no further long-term toxicity test to fish is proposed. Available short-term studies for fish, aquatic invertebrates and algae, all indicate no potential for aquatic toxicity. Moreover NOEC values obtained from algal growth studies and daphnia reproduction studies are clearly above the limit of water solubility. As there was no sign that invertebrates are less sensitive than fish in the short-term tests, it cannot be expected that a long-term test with fish will generate different results than the existing long-term tests with aquatic invertebrates. Due to their ready biodegradability it is not likely that aquatic organisms will be exposed to the LCAE category members since they will be ultimately degraded in sewage treatment plants. Thus, based on the above mentioned results, it can be excluded that any substance within the category will exhibit chronic toxicity to fish up to the limit of water solubility. Hence due to animal welfare reasons and to avoid unnecessary vertebrate tests, no further long-term test with fish was proposed.
