In accordance with column 2 of REACH Annex IX, Bioaccumulation in aquatic species (required in section 9.3.2) was not conducted as direct and indirect exposure of the aquatic compartment is unlikely. From experience in handling and use it is very unlikely that direct and indirect exposure of the aquatic compartment occurs, as the substance rapidly hydrolysis in contact with water (see IUCLID5 section 5.1.2) and is highly insoluble in 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. In addition based on the very high predicted log Pow of over 10 (14.22 as estimated by EPIWIN) the substance has a very low potential to pass biological membranes and thus will not be easily bioavailable. Furthermore, 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. Further, the test substance is considered to be readily biodegradable.
