- 90 vol%
- Conclusions:
- Naphthenic acids, zinc salts was determined not to be surface active at 20°C by the harmonized ring method. The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 61.6 mN/m.
- Executive summary:
The surface activity of naphthenic acids, zinc salts was determined in a GLP-compliant harmonized ring method test, following OECD guideline 115 (CRL 2018). The study is considered relevant and reliable for use. Naphthenic acids, zinc salts was determined not to be surface active at 20°C by the harmonized ring method. The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 61.6 mN/m.
