Applicant's summary and conclusion
- Conclusions:
- The values of the single determinations show no significant difference (2.00% between
mean values of the two measurement series). All measured values lay above the threshold
for surface tension which is stated in the guidelines.
The surface tension of the negative control was determined with a difference of 0.01 %
from the stated literature value.
Therefore, the result of the test is considered valid and the test item
Allyltributylphosphonium chloride is classified as “not surface active” in a concentration
of 1.00 g/L. - Executive summary:
The surface tension of an aqueous solution of Allyltributylphosphonium chloride was determined
as 67.39 ± 0.12 mN/m at 19.9 °C. One measurement was performed for verification
(after 59 minutes). No significant changes and thus no significant dependence on time
was observed.
As these values were higher than 60 mN/m, Allyltributylphosphonium chloride was classified
as
not surface active.
The surface tension of the negative control lay within the accepted range.
