In accordance with Sect. 9.4, Col. 2
Annex IX of REACH Regulation (EC) No 1907/2206 the performance of a test
for toxicity to soil microorganisms was considered scientifically not
justified. Direct exposure to the terrestrial compartment is not
intended. In addition, indirect exposure to the soil compartment via
sewage sludge can practically be excluded, since the substance is
hydrolytically unstable. In a biodegradation study (MITI, 2011), the
test substance Sika Hardener LH was completely hydrolyzed to
2,2-dimethyl-3-oxopropyl dodecanoate and hexamethylenediamine. These
converted products were biodegraded. The percentage (average) of
biodegradation by BOD was 91 % after 28 days. Therefore, the test
substance is considered to be readily biodegradable. During professional
and consumer use, the substance is incorporated in a polymer matrix, and
is in conclusion not present as such in the environment. Safe use was
shown in the CSR for all uses and environmental compartments. In
conclusion, the CSR does not indicate the need to investigate further
no tests on soil microorganisms are provided.
