- Conclusions:
- Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The water solubility of the test item at a temperature of 20 °C was determined to be 35 mg/L (+/- 3 mg/L). - Executive summary:
The water solubility of the test item Methyl-4-tert-butylbenzoate at a temperature of 20 °C was determined to be 35 mg/L (+/- 3 mg/L).
Reference
Different amounts of the test item and water were treated with ultrasound or stirred at room temperature until the mixture appeared dissolved or the water solubility could be estimated to be below 10
mg/1. According to the preliminary visual estimation the water solubility of the test item is between 30 mg/l and 94 mg/1. Consequently the flask method was performed as main test.
