Applicant's summary and conclusion
- Conclusions:
- The surface tension of an aqueous solution of 5-Aminotetrazol Potassium was determined as 72.38 ± 0.08 mN/m at 20.1°C. As these values are higher than 60 mN/m, the test item 5-Aminotetrazol Potassium is classified as not surface active.
- Executive summary:
The surface tension of an aqueous solution of 5-Aminotetrazol Potassium was determined as 72.38 ± 0.08 mN/m at 20.1°C. One additional measurement was performed for verification (after 60 minutes). No significant changes and thus no significant dependence on time and temperature were observed. As these values are higher than 60 mN/m, the test item 5-Aminotetrazol Potassium is classified as not surface active. The surface tension of the negative control lay within the accepted range.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
