Description of key information
No mortality was observed within the water solubility of the test substance.
Key value for chemical safety assessment
Additional information
No tests with homosalate itself are available. Read-across to the structurally very similar 2 -ethylhexyl salicylate was done (see read-across justification in IUCLID section 13 respectively in the appendix to the CSR).
In all three fish tests with 2 -ethylhexyl salicylate no mortality was observed within water solubility. The key study (Scheerbaum, 1996) showed that even in an emulsion with 100 mg/L nominal, no effects were observed (LC50 > 82 mg/L measured conc.). A study using an emulsifier (Caspers, 1996) showed as well no mortality up to the water solubility limit (LC0 >= 0.22 mg/L; loading rate 2.5 mg/L). In a third study (Caspers, 1992) the toxicity was tested far above the water solubility of the substance (62 to 1000 mg/L). Up to 250 mg/L (nominal) no mortality was observed. The LC50 was determined to be 613 mg/L (nominal), where the mortality can be attributed to physical effects instead of systemic effects.
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).
