Additional information
The ready biodegradability was determined with a non-adapted activated sludge for the test item
WOLLWACHSALKOHOL/LANOLINALKOHOL batch no. Eucerit 6480 over a test period of 28 days in the Modified Sturm Test. The study was conducted from 2001-06-07 to 2001-07-06 according to OECD 301 B/C02 evolution test in the DR.U.NOACK-LABORATORIUM FÜR ANGEWANDTE BIOLOGIE.
The 10 % level (beginning of biodegradation) was reached after a adaptation period of 9 days. In the 10 -day-window the mean biodegradation came only to 21 %. The pass level of a biodegradation > 60 % was not reached neither in the 10 -day-window nor after 28 days.
The test item must be regarded to be not readily biodegradable in the 10-day-window and after 28 days. The validity criteria according to the guideline are fulfilled.
The test material attained 39 % degradation after 28 days and therefore cannot be considered to be readily biodegradable under the strict terms and conditions of OECD Guideline No 301B.
