In accordance with column 2 of REACH Annex
IX, Soil simulation testing (required in section 188.8.131.52) was not
conducted as the substance is highly insoluble in water and
hydrolytically unstable (see IUCLID5 section 5.1.2). In addition, 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.
From experience in handling and use it is very unlikely that direct and
indirect exposure of soil occurs, as the substance rapidly hydrolysis in
contact with water. In addition, the substance is incorporated in a
polymer during professional and consumer use and is thus not present in
the environment as such.
