Description of key information

A study on hydrolysis according to the OECD Test Guideline 111 with Reaction mass of decyl acrylate and octyl acrylate was performed. After 5 days at each pH, the test item was shown to have hydrolysed by more than 10% compared to T0. This indicated that the test item was hydrolytically unstable and significant hydrolysis had occurred at each pH.

The half-lives obtained were:

6.3 days at pH 1.2

12.8 days at pH 4

9.6 days at pH 7

0.65 days at pH 9
