Applicant's summary and conclusion
- Conclusions:
- The surface tension of 2-Hydroxydecanoic Acid was determined to 24.4 mN/m at 23.1 °C and pH 3.2 depending on the used procedure.
- Executive summary:
The surface tension of 2-Hydroxydecanoic Acid was determined to 24.4 mN/m at 23.1 °C and pH 3.2 depending on the used procedure.
2-Hydroxydecanoic Acid shows a surface tension lower than 60 mN/m. It is a surface-active material.
The execution of the determination at a temperature 3.1 °C higher than as prescribed in Method A.5 of Commission Regulation (EC) No. 440/2008 has no influence on the evaluation.
