The test item has a mean surface tension of 66.04 mN/m. According to regulation EC No. 440/2008 Part A Method A.5 substances showing a surface tension lower than 60 mN/m under the conditions of method A.5 should be regarded as being surface active materials.Thus, the test item is not to be regarded as surface active.
Applicant's summary and conclusion
- Conclusions:
- The surface tension at 20 °C of the test item 5-(Hydroxymethyl)furfural was determined to be 66.04 mN/m. Therefore, it is not to be regarded as surface active material.
- Executive summary:
According toOECD Test Guideline 115 and Regulation EC No. 440/2008 Part A Method A.5. the surface tension at 20 °C of the test item5-(Hydroxymethyl)furfuralwas determined to be: 66.04 mN/m
According to RegulationEC No. 440/2008 Part A Method A.5. the test item is not to be regarded as surface active material.
