Description of key information

The substance, di-pentaerythritol, is not readily biodegradable.

Key value for chemical safety assessment

Additional information

The potential for biodegradation of di-pentaerythritol was determined in a study according to SS-EN ISO 7827:1996/OECD 301 A. The quantity of test substance DOC that was degraded in this study was less than 20%. According to OECD guidelines for testing chemicals, a test compound is regarded as easily biodegradable if the loss of DOC within 28 days is greater than 70 %. This criterion was not reached for the test article and, as such, Di-Pentaerythritol cannot be regarded as readily biodegradable.

In a further supportive study the aerobic biodegradability of di-pentaerythritol was investigated in a study with methodology closely corresponding to OECD 301 D. The results of this study suggested that little biodegradation took place during the test period.
