Applicant's summary and conclusion
- Conclusions:
- CIT is to be classified as non-surface active according to EC Guideline A.5.
- Executive summary:
The surface tension of aqueous solutions of CIT determind according OECD 115 with concentrations of approx. 1g/L was
determined to be 71 mN/m at 20 °C.
