Description of key information

Determination of Biodegradability of butylal in the Manometric Respirometry Test (according to Annex of EEC-Directive 92/69; corresponds to OECD Guideline 301 F and ISO Standard 9408) shows:

Biodegradation degree (BOD of ThOD) after 28 days : 30 - 40 %

Biodegradation degree (BOD of ThOD) after 34 days : 40 - 50 %

The test substance is in this test partly or moderately biodegradable and not readily biodegradabie (according to OECD criteria).

Key value for chemical safety assessment
