Applicant's summary and conclusion
- Conclusions:
- The determination of the surface tension was performed according to the OECD ring method. The surface tension of N-(Isopropoxycarbonyl)phophoric acid triamide (P204/98) is 44.9 mN/m (value 50 hours after start of measurement). If the surface tension is < 60mN/m, the test item is surface active. Due to the final result it can be concluded that the test item is surface active.
- Executive summary:
The determination of the surface tension was performed according to the OECD ring method. The surface tension of N-(Isopropoxycarbonyl)phophoric acid triamide (P204/98) is 44.9 mN/m (value 50 hours after start of measurement). If the surface tension is < 60mN/m, the test item is surface active. Due to the final result it can be concluded that the test item is surface active.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
