EC number: 254-179-7
CAS number: 38888-98-1
Available information:SAS-40 In a 96-h acute toxicity study, zebra fish (Danio rerio) were exposed to SAS-40 at nominal concentrations of 0 (control and solvent control), 1, 2.24, 5, 11.18 and 25 mg/L under static conditions. The LC50 based on the nominal concentration was 8.4 mg/L. The results have to be interpreted with caution since the LC50 is on the limit of water solubility of SAS-40. SAS-296: In a 96-h acute toxicity study, rainbow trout (Oncorhynchus mykiss) were exposed to SAS-296 at nominal concentrations of 0 (control and solvent control) and 0.56 mg/L under static conditions. The LD50 was greater than the solubility limit of 0.56 mg/l. Water concentrations were not measured and the poor solubility of test substance requires a careful interpretation of test results. SAS-296:The toxicity of 1,4-dimethyl-2-(1-phenylethyl) was determined in a freshwater fish, Orizias latipes according to OECD 203. A 96h LC50 of 0.31 mg/L was reported QSARs - Data based on calculations using EPI Suite v4.10 (KOCWIN (Molecular Connectivity Method; worst case)/ ECOSAR Program v1.00. ECOSAR is a known and reliable calculation tool for this endpoint and therefore this estimation can be used in a weight-of-evidence approach. For PTE the calculated 96 h LC50 was 0.64 mg/L, for 11-DPE was 1.8 mg/L, for BT was 0.78 mg/L, for SAS-296 was 0.226 mg/L and for SAS-305 was 0.12 mg/L.
The key studies for the effect assessment
are reliable with restrictions and were conducted according to an
internationally accepted guideline. The lowest LC50 value is read across
to 1,1 -DPE. No further testing is required.
For detailed read across rationale and
justification see section 13, Read across document.
