EC number: 607-759-2
CAS number: 25618-55-7
Readily biodegradable: > 70 % in 28 days (OECD 301 B)
Three studies investigating the biodegradability
of 1,2,3-Propanetriol, homopolymer (CAS 25618-55-7)
are available. The key study were conducted according
to OECD guideline 301B and GLP using non-adapted,
domestic activated sludge as inoculum (BASF 2017). A
test substance concentration of 20 mg/L as TOC was
applied. Based on C02 evolution biodegradation of
70-80% after 28 days and 80-90% after 60 days were
measured. The 10d-window was not passed; however,
since the test substance is a UVCB substance composed
of different homologues sequential degradation can be
assumed and thus the 10d-window should not be applied.
Hence, the test substance is considered to be readily
Further supporting studies and QSAR calculations
support the assumption of ready biodegradability, even
if the pass level for ready biodegradability could not
be reached in a ready biodegradability test performed
according to OECD guideline 301D (BASF 1990).
