Description of key information

With high probability no toxic effects on aquatic algae in the range of water solubility.

Key value for chemical safety assessment

Additional information

Since no test data on acute toxicity of the test substance to aquatic algae are available a conclusion by analogy approach to the structure analogue substance 4,6-bis(octylthiomethyl)-o-cresol (CAS 110553-27-0) has been applied.

In this GLP limit test conducted according to OECD guideline 201, no effects of the structure analogue substance at the highest test concentration of 100 mg/l on the growth of Scenedesmus subspicatus was observed. The total mean measured concentration with 100 mg/L loading was calculated as 0.008 mg/l during the test.
