Description of key information

Di-pentaerythritol is stable to hydrolysis at environmentally relevant pH ranges, i.e. half life of greater than 1 year. 

Key value for chemical safety assessment

Additional information

A test was conducted according to OECD 111 to assess abiotic hydrolytic transformations of di-pentaerythritol in aquatic systems at pH values normally found in the environment (pH 4 – 9). After 5 days, no significant transformation was observed. As such di-pentaerythritol cannot be considered to be rapidly hydrolysed and the results suggest that abiotic removal by hydrolysis will not be an important pathway of degradation for di-pentaerythritol in the environment. It is therefore estimated that di-pentaerythritol will have a hydrolytic half life of greater than 1 year at environmentally relevant pH`s (4 -9) and temperatures (20 °C).
