EC number: 947-384-4
CAS number: -
The substance is characterized by a water solubility of < 1.51
mg/L at 20 °C (OECD 105), a vapour pressure of 0.588 Pa at 25 °C
(EpiSuite v4.11) and a log Koc of 4.08 - 13.1 (EpiSuite v4.11). Thus, if
the substance is released to the environment it has a high potential for
adsorption to sediment and soil particles. Hydrolysis is not considered
to be a relevant degradation pathway since QSAR calculations do not
indicate a fast hydrolysis under environmental conditions. Moreover,
sterical hindrance of the glycosidic bond by fatty acids does not allow
for significant hydrolysis. Thus, the substance is considered to be
hydrolytically stable in the environment. Significant biodegradation by
activated sludge microorganisms is not expected. 19-28% degradation was
recorded in a standard biodegradation study according to OECD 301D and
66.6% degradation was observed in an inherent biodegradation study
according to OECD 302C. Thus, the substance is primary biodegradable but
not readily biodegradable according to the OECD criteria. Even though
the substance is stable in the environment, bioaccumulation is
considered to be low based on the log Pow values of the different
constituents of the UVCB substance.
