Results and discussion

Surface tension
Key result
Remarks on result:
not determinable
Remarks:
The solubility of the sample was < 1 mg/L and therefore no further testing is required.

Any other information on results incl. tables

- A solution of 1 g/L was prepared. After shaking the majority of the sample sank to the bottom of the glassware. After 20 minutes sonication the sample remained insoluble.

- A second solution of 1 mg/L was prepared which sank to the bottom of the glassware. After 30 minutes of sonication the sample remained insoluble.

- The solubility of the sample was < 1 mg/L and therefore no further testing is required.

- The endpoint it exempt under Column 2 of Annex VII (EC 440/2008) as the water solubility is < 1 mg/L.

Applicant's summary and conclusion

Conclusions:
In accordance with Column 2 of Annex VII (EC 440/2008) the endpoint is exempt as the water solubility is < 1 mg/L.
Executive summary:

The surface tension of the test material was investigated in accordance with the standardised guidelines OECD 115 and EU Method A.5, under GLP conditions using the ring method.

A solution of 1 g/L was prepared. After shaking the majority of the sample sank to the bottom of the glassware. After 20 minutes sonication the sample remained insoluble. A second solution of 1 mg/L was prepared which sank to the bottom of the glassware. After 30 minutes of sonication the sample remained insoluble. The solubility of the sample was < 1 mg/L and therefore no further testing is required.

In accordance with Column 2 of Annex VII (EC 440/2008) the endpoint is exempt as the water solubility is < 1 mg/L.
