*The mixture was treated in an ultrasonic bath.

The solubility of the test item in water at room temperature was estimated to be < 9.8 mg/L.

Final Results

According to OECD Test Guideline 105 (1995) and Regulation EC No. 440/2008 Method A.6. the water solubility of the test item Na-ETS-4was estimated by performing the preliminary test to:
cS < 9.8 mg/L

Description of key information

< 9.8 mg/L under ambient conditions (Flask method preliminary test, OECD 105)

Key value for chemical safety assessment
