Additional information

Only an inherent biodegradability test according to the OECD Guidelines for Testing of Chemicals (1992) No. 302B, was performed with the test substance. Under the conditions of the test 0% was degraded after 28 days of exposure time.

The test item cannot therefore be considered as inherently biodegradable under the experimental conditions employed in this study.

FAT 40871/A TE is not inherently biodegradable.

Regarding the hydrolysis properties of the test item, FAT 40871/A TE, was tested in a valid GLP study in accordance with the OECD Guideline 111 (Hydrolysis as a Function of pH).

The substance was found to be hydrolytically stable at pH 4, 7 and 9 with a predicted half-life of 1 year, 99.4 hours and 182 days respectivelly at 25 °C.

As the pH 7 and pH 9 results indicate that the rate of hydrolysis increases with a decrease in pH, it can be concluded that the test item will hydrolyse extremely rapidly at pH 4. However, as this wasn’t indicated by the pH 4 results, it is likely that the main “test item” peak in the pH 4 standards and samples was due to a stable, hydrolysis product (as opposed to the parent test item).
