Key value for chemical safety assessment

Additional information

One guideline study investigating the ready biodegradability of Uvinul A Plus is available. The biodegradation of the substance was tested in a Manometric Respirometry Test according to OECD guideline 301F using domestic activated sludge as inoculum. At test termination after 28 days Uvinul A Plus was degraded by 0 - 10 % (BASF AG, 2001). Thus, Uvinul A Plus is not readily biodegradable according to OECD criteria.
