Description of key information

Ready Biodegradation: 36% in 28 days (OECD 301D)

Key value for chemical safety assessment

Additional information

A ready biodegradation of 36% has been determined for Tall Oil Pitch (TOP) using a method in accordance to OECD 301D (Closed Bottle Test). All validity criteria relevant to the test were met. The data was considered reliable, adequate for environmental assessment and selected as key study.

In other supporting study, a ready biodegradation of 9.2% (OECD 301B) has been determined for the test substance. The available studies gave consistent results that are adequate for assessing the biodegradation of the test substance. Tall Oil Pitch is considered not readily biodegradable.
