a standard 301F ready biodegradation Vammar D10 achieved 33%
biodegradation in 28 d. In an enhanced OECD 301F test with acclimated
sludge, 63% biodegradation of Vammar D10 was achieved after 28 dand
81.5% was reached after 60 days.In this enhanced test, the
non-acclimated test system reached 41.8% in 28 days and 51.3% by the end
of the test (68d). Vammar D10, although not readily biodegradable,has
been shown to be inherently degradableand as such does not meet the
criterion for persistence according to REACH Guidance R.18.104.22.168"
simulation biodegradation studies are not technically feasible for
petroleum-derived UVCB substances, therefore in accordance with Annex XI
Section 1.3 testing is not scientifically necessary and the endpoint has
been fulfilled using QSAR calculations for relevant constituents. Full
justifications for this QSAR are presented in 'Attached justification'
within the individual study records, but in brief these are justified
the results are obtained from a QSAR model whose scientific validity has
been established (CATALOGIC v5.11.19)
Identified substance constituents fall within the applicability domain
of the QSAR model
results are adequate for the purposes of risk assessment
adequate and reliable documentation is provided
