Additional information

Acid chlorides, coco:

The toxicity of acid chlorides, coco (CAS 68187 -89 -3) was studied under GLP following OECD 202 (BASF SE, 2012; project no. 50E0399/11X282). The test species was Daphnia magna. The test was performed under static condistions with analytical monitoring of the test item concentrations. Besides testing the test item without pH-adjustment, a neutralised test solution was run in addition. The 48 -h EC50 was determined to be 141 mg/L (not neutralised, measured). After adjustment of the pH value, no effect was observed at 800 mg/L (measured).

 

Hydrochloric acid:

The hydrolysis product hydrochloric acid (HCl) was tested in a semi-static acute toxicity test according to OECD 202 with Daphnia magna. The 48-h EC50 was 0.492 mg/L (acid equivalent to pH 5.3; OECD 2002).
