Additional information
Toxicity to aquatic invertebrates
In a semi-static short term study the surrogate test item was found to affect the mobility of Daphnia magna after 48 hours with the following effect values (based on geometric mean measured test item concentrations): The EC50 and EC10-values were 4.2 mg/L and 2.9 mg/L.
Toxicity to alga and cyanobacteria
In a static short term study the surrogate test item isobutyl salicylate was found to inhibit the growth of the freshwater green alga Pseudokirchneriella subcapitata after 72 hours with the following effect values (based on geometric mean measured test item concentrations): The EC50 and EC10-values for inhibition of growth rate were 0.791 mg/L and 0.614 mg/L respectively. The NOEC-values for both inhibition of growth rate and yield after 72 hours were 0.173 mg/L, respectively.
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.
