CAS number: 68512-30-1
In ready biodegradability tests, no biodegradation of the
substance and of two of its components was observed. It is concluded
that the substance may not be biodegradable and could meet the P
criterion of Annex XIII of Regulation (EC) no 1907/2006.
In bioaccumulation studies with fish using the substance itself
(dietary exposure) and of two of its constituents (substituted phenol
and non-phenolic constituent) (aqueous exposure), BMF and BCF were
determined. For the dietary exposure study, only BMF but no reliable BCF
values were derived. BCF values determined in the two aqueous exposure
studies ranged from ca. 200 to ca. 2800 L/kg. A preliminary estimate
obtained from the dietary study but not suited for assessment indicates,
that BCF values for the trimeric constituents of OAPP may fall in a
range above 5000. Presently, a BCF for the substance is set at 3000 thus
not meeting the vB criterion.
T criteria are not fulfilled either with regard to aquatic
toxicity, or with regard to carcinogenicity, mutagenicity and
reproductive toxicity, or with regard to other evidence of chronic
Overall, the substance Oligomerisation and alkylation reaction
products of 2-phenylpropene and phenol is assessed not to be a PBT
