Details on results:

Using HYDROWIN v2.00 (September 2010), © 2000 U.S. Environmental Protection Agency, all nine potentially hydrolysable components of the test item were considered to be stable towards hydrolysis at pH 4, 7 and 9.

Validity criteria fulfilled:

not applicable

Conclusions:

It was concluded that the test item would be stable towards hydrolysis at pH 4, 7 and 9.

Executive summary:

FAT 93580/A was evaluated for hydrolytic stability. Due to the complex nature and low solubility of the test item in water, it was considered that determination of the hydrolytic stability according to Method 111 of the OECD Guidelines for Testing of Chemicals, 13 April 2004 was not feasible.

A preliminary scientific assessment of the main constituent (ten components) of the test item indicated that nine of these components contained at least one potentially hydrolysable functional group; whereas, the remaining component did not contain any hydrolysable functional groups, and thus, would be stable towards hydrolysis.

The hydrolytic stability of each of the nine, potentially hydrolysable components was estimated using the specialist estimation software, HYDROWIN v2.00 (September 2010), © 2000 U.S. Environmental Protection Agency.

Hence; it was concluded that the test item would be stable towards hydrolysis at pH 4, 7 and 9.

Description of key information

Hence; it was concluded that the test item would be stable towards hydrolysis at pH 4, 7 and 9.

Key value for chemical safety assessment
