Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
Distribution
Adsorption to organic particles:
In view of the adsorption/desorption screening test,
adsorption coefficients on soil for both components of the
substance are:
Koc = 3200 (log Koc = 3,5) for 6PPD
Koc= 25000 (log Koc = 4,4) for p-cumyl-6PPD.
The substance is expected to be immobile in soil [Mensik et al 1995]
Based on the Log Kow, transport of the compound from water
to soil/sediment is expected. The values of water solubility
and vapour pressure indicate that the transport from water
to air is of low relevance.
Chemical degradation:
The notified substance is an antioxidant and antiozonant and
as such necessarily reacts very quickly with oxygen.
Therefore fast oxidation in diluted solution, where oxygen
is readily available, is to be expected. Based on the results of
modified test of hydrolysis as function of pH it is possible to state
that Dusantox L in the aqueous medium is subject to hydrolysis, which is
depended on pH and temperature. In buffered aerobic solution at pH 7 and
25°C, the half lives of the two main components 6PPD and cumyl 6PPD are
3,3 and 9 h, respectively, which increased to 4,9 h and 10,2 h at 15°C.
The half lives at pH 10 and 25°C are 6,4 and 16,7 which increased to
13,7 h and 31,5 h at 15°C.
Biodegradation
As the biodegradation tests clearly show, Dusantox L is not readily
biodegradable. The three tests on ready biodegradation ( OECD 301 B, 301
D, 301 F) indicates 46%, 33%, and 9% degradation after 28 days. The used
substance concentration 18,2 mg/l and 100 mg/L could not have inhibiting
activity on the microbial polulation, since the EC 50 for activated
sludge was determined to > 2000 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
