EC number: 291-807-9
CAS number: 90480-71-0
Simulation test: ISO 11733: 1995 - 98% mineralisation (last 30 days of test)
In accordance with Column 2 of REACH Annex IX, the simulation test on
ultimate degradation in surface water and the sediment simulation test
(required in Sections 184.108.40.206 and 220.127.116.11 respectively) do not need to
be conducted as the substance is readily biodegradable. Identification
of degradation products (required in Section 9.2.3) is also not
Radiolabelled pentadecanol (branched with an average of 1.4 branches)
was studied in a model continuous activated sludge (CAS) plant. The
CAS plant was fed daily with fresh domestic sewage, and the input
concentration of pentadecanol was 1 mg/l, dispersed with a surfactant.
The study duration was 53 days, allowing for a stabilisation period
followed by a measurement period. Over the last 30 days of the study
the substance was 98% mineralised, with 0.05% pentadecanol remaining
in the effluent, and 0.4% of the radioactivity adsorbed to the sludge.
The overall removal from influent was >99.9%, and removal from the
total system was 99.5%. Of the remaining (non-mineralised)
radioactivity there was evidence of more polar metabolites being
formed as well as lipids derived from the alcohol.
The study is Klimisch 1. GLP applies to a study conducted in
accordance with an ISO method (ISO 11733:1995) comparable to the OECD
303 method (EU C.10).
