EC number: 205-117-2
CAS number: 133-66-4
Read-across proposed with CAS 16090-02-1No biodegradation observed
A study on the biodegradability in water of a close structural analogue
(CAS 16470-24-9) is available.
In the ready biodegradability test according to OECD guideline 301A a
DOC removal of 1.2 % was observed (CIBA - GEIGY 1992). Hence, the
substance was not readily biodegradable.
biodegradation has been calculated using BioWin v.4.10 and no ready
biodegradabilty was predicted.
Therefore, the stilbene fluorescent whitening agent with CAS 133-66-4
is considered to be not readily biodegradable.
