A variation in the measured surface tension during the test time period indicates that there is an ageing effect.
Applicant's summary and conclusion
- Conclusions:
- Test 1. 57.6 mNm-1 at 22°C (1.042% w/v solution) Test 2. 65.6 mNn-1 at 22°C (0,0948% w/v solution)
A variation in the measured surface tension during the test time period indicates that there is an ageing effect associated with this endpoint. No further investigations where conducted and this was not considered to effect the integrity of the study. - Executive summary:
A variation in the measured surface tension during the test time period indicates that there is an ageing effect associated with this endpoint. No further investigations where conducted and this was not considered to effect the integrity of the study.
The substance is not considered to be a surface active material.
