- Certificate of Analysis Date: February 17, 2017
- Physical Appearance / Colour: Solid / White
- Water Solubility: > 543 g/L (20 °C)
- Expiry Date: February 03, 2019
- Storage Conditions at Test Facility: at 20 °C ± 5 °C, in the dark - Key result
- Surface tension:
- 33.4 N/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of an aqueous solution of the test item (1g/L) was determined to be: 33.4 mN/m at 20 °C.
- Executive summary:
The purpose of the study was to determine the surface tension of an aqueous solution of the test item means of a ring tensiometer.The study was performed in accordance with OECD 115. In conclusion, the surface tension of an aqueous solution of the test item (1g/L) was determined to be: 33.4 mN/m at 20 °C. Therefore, Benzethonium chloride needs to be regarded as surface active material.
