Two studies were conducted to investigate the ready biodegradability of
the substance. Both were conducted in accordance with standardised
guidelines under GLP conditions and awarded a reliability score of 1 in
accordance with the criteria for assessing data quality set forth by
Klimisch et al. (1997).
The key study has been selected on the basis that the OECD 301 B study
is historically more sensitive than the OECD 301 C study. In this key
study, the substance attained 74 % degradation after 28 days and
satisfied the 10-Day window validation criterion. The test material can
therefore be considered to be readily biodegradable.
In the supporting study, the biodegradation of the test material was
investigated in accordance with the standardised guideline OECD 301 C
under GLP conditions. Some of the anionic component of the test material
(1,2-cyclohexanedicarboxylic acid ion) was biodegraded by microorganisms
and changed into a structure-unknown converted product. The
structure-unknown converted product and the rest of the anionic
component of the test material were not biodegraded by microorganisms
and remained. In this study biodegradation levels were determined to be
in the 15-21% range.
Given that the substance was determined in the key screening study to be
readily biodegradable, no higher level biodegradation testing has been
proposed by the registrant.
