Description of key information
Long-term invertebrate studies are not required based on exposure considerations.
Key value for chemical safety assessment
Additional information
According to REACH REGULATION No 1907/2006 (EC), Official Journal of the European Union L 396/354, the study does not need to be conducted since the chemical safety assessment does not indicate the need to investigate further the effects on aquatic organisms.
Homosalate has shown no signs of toxicity when tested in acute tests at three trophic levels (fish, algae and daphnia) within the water solubility. In the algae test it was observed that the concentration of homosalate in the test system could not be maintained over 72-hours and no substance was detectable after 72hours (0h: 19µg/L; 72h: < LOQ). Furthermore it is known that homosalate hydrolyses quite fast under environmental conditions (pH 7) in the aquatic environment with a half-life of only 9 days. Therefore the substance can be regarded as rapidly degradable in the aquatic environment (according to CLP/GHS criteria) and is not expected to be present in the aquatic system for a longer time. The hydrolysis degradation products salicylic acid (2-hydroxylbenzoic acid) [CAS 69-72-7] and 3,3,5-trimethylcyclohexanol [CAS 116-02-9] are as well not classified as hazardous to the aquatic environment.
Furthermore an exposure assessment for the environment (surface water, sediment, soil) was carried out and shows that there is no risk for the aquatic environment (RCR < 1). Also the PEClocal and PECregional are <1/100th of the water solubility.
Thus, the chemical safety assessment does not indicate the need to investigate further the effects on aquatic organisms.
