Description of key information

In contact with water no hydrolysis of sodium acrylate will be observed.

Key value for chemical safety assessment

Additional information

No data on hydrolysis of sodium acrylate are available; therefore, this parameter is covered by the structural analogue acrylic acid.

A study showed that 14C-acrylic acid was stable to hydrolysis at pH 3, pH 7, and pH 11 at 25°C. Since 14C-acrylic acid was stable at these pH values, no rate constants or half-lives were calculated. Therefore, hydrolysis will not contribute significantly to the abiotic degradation process of neither acrylic acid nor sodium acrylate.
