Key result

Remarks on result:

not determinable because of methodological limitations

Details on results:

The test item is a UVCB that contains reaction products of 1-octanol and phosphorus pentoxide. The reaction products are mono‐, di‐ and trioctanyl phosphate esters and a mixture thereof. As a consequence, this mixture contains already compounds that can be obtained also during the hydrolysis study. Some of the esters produced during the hydrolysis study will be the same as the initially present esters. Since, it is not possible to differentiate the hydrolysis products from the initially present reaction products, the hydrolysis study cannot be performed.

Validity criteria fulfilled:

not applicable

Conclusions:

The test item is a UVCB that contains reaction products of 1-octanol and phosphorus pentoxide. The reaction products are mono‐, di‐ and trioctanyl phosphate esters and a mixture thereof. As a consequence, this mixture contains already compounds that can be obtained also during the hydrolysis study. Some of the esters produced during the hydrolysis study will be the same as the initially present esters.
