EC number: 225-805-6
CAS number: 5089-70-3
Testing is waived on the basis
that the chemical safety assessment according to Annex I indicates that
it is not necessary to conduct the simulation test on ultimate
degradation in surface water and the sediment simulation test, or to
identify degradation products.
Simulation tests (water and
sediments) are not considered necessary because:
· The substance hydrolyses
moderately rapidly to form (3-chloropropyl)silanetriol and ethanol. The
parent substance and the silanol hydrolysis product have log Kow
values of 3.13 and -1.1 respectively and, therefore, exposure of the
sediment compartment is expected to be low.
· The risk characterisation
ratios (RCRs) for the aquatic and sediment compartments, based on the
assumption that both the parent substance and the silanol hydrolysis
product are not biodegradable, are <1.
· The non-silanol
hydrolysis product, ethanol, is readily biodegradable.
