Description of key information
The toxicity of the target substance to microorganisms was assessed by category read-across to other linear saturated substances in the alkyl ether sulfates (AES) category. Based on the read-across a NOEC (14 d) of 54.8 mg/L is assumed for the target substance.
Key value for chemical safety assessment
Additional information
The toxicity of the alkyl ether sulfates (AES) substances to microorganisms was assessed by read-across based on the grouping of substances (category approach). All data on toxicity to microorganisms available for the category were used to assess the toxicity of category substances to microorganisms. The available data indicate no adverse effects of alkyl ether sulfates on microbial activity. All substances of the alkyl ether sulfates category are considered readily biodegradable. In the available screening studies including a toxicity control, no inhibition of the degradation process by the test substance was observed. The available studies investigating the respiration inhibition of activated sludge organisms and Pseudomonas putida determined no detrimental effects of the tested alkyl ether sulfates.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
