Thus, the following value for water solubility of the test item Stearyl Erucamide can be reported according to test procedure according to EU test method L142A/57-66 (EEC A.6).
Water solubility Stearyl Erucamide < 0.05 mg/L
pH value HPLC water: 6.4
The water solubility was determined at 20 °C.
Working range
The calibration curve fits over the whole working range from 0.05 to 2.05 mg/L with r2= 1. A quadratic fit was used.
Recovery
In the course of the recovery experiment, an average recovery rate of 99 % was determined.
Description of key information
< 0.05 mg/L at 20 °C
Key value for chemical safety assessment
- Water solubility:
- 0.05 mg/L
- at the temperature of:
- 20 °C
Additional information
A water solubility value of < 0.05 mg/L at 20 °C was determined according to EU Method A.6 (column elution).
