Description of key information
Aryl sulphonate condensate can be regarded as being non-toxic to aquatic algae Selenastum capricornutum and cyanobacteria under the conditions of the experiment given a calculated EC50 of 330 (biomass) and 1000 mg/l (growth rate), which are greater than the 96-hour EC50 threshold value (for algae or other aquatic plants) of 1 mg/l (CLP Regulation (EC) No 1272/2008). The 96-hour NOEC according to biomass and growth rate was determined to be 100 and 32 mg/l, respectively.
Following an acute toxicity test to Daphnia magna, Aryl sulphonate condensate was calculated to have a 24-hour EC50 of 777 mg/l and a 48-hour EC50 of 529 mg/l. It can be concluded that aryl sulphonate condensate is not a short-term aquatic hazard to aquatic invertebrates as the 48-hour EC50 is greater than the cut-off value of 1 mg/l (CLP Regulation (EC) No 1272/2008).
Based on the summary of an acute toxicity experiment with Salmo gairdneri, the 96-hour LC50 of Aryl sulphonate condensate was concluded to be >100 mg/l. However, as the full test report was not available this information should not be used for classification.
Based on the information available, the Aryl sulphonate condensate is concluded to be non-toxic to aquatic plants and organisms.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
