Applicant's summary and conclusion

Conclusions:

The test item was determined to be stable at a nominal concentration of 10 g/L solution in acetone, n-octanol and methanol for at least 28 days at 25± 2ºC. This conclusion was drwaun from the absence of any significant changes (<5%) in the concentration of the test item in solution over the incubation period.

Executive summary:

The test item was determined to be stable at a nominal concetration of 10 g/L solution in acetone, n-octanol and methanol for at least 28 days at 25 ± 2ºC. this conclusion was drawn from the absence of any significant changes (<5%) in the concentration of the test item in solution over the incubation period.
