Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
As the substance is readily biodegradable (OECD 301B), has a low (photo-) stability in air and is not directly applied to the soil, direct and indirect exposure of the soil compartment is unlikely.
Additional information
There is no information concerning terrestrial toxicity of Butyldiglycol methacrylate available.
However, the substance shows a low adsorptive as well as a low bioaccumulative potential (based on log Pow = 3.1 (measured) and fast metabolisation). According to test guideline OECD 301 B Butyldiglycol methacrylate was assessed to be readily biodegradable (meeting 10-d window criteria) in sewage sludge (CIT, 2000). Therefore the direct exposure of soil due to STP sludge application can be negelcted.
Results from a Mackay level III distribution modelling indicate that if Butyldiglycol methacrylate is released into water, it mainly remains in water (99.7%). If the substance is released to air, it mainly distributes to soil (77.9%) and a small amount remains in the air (11.2%) or partitions to water (10.8%) (see chapter 5.4.3 Distribution modelling). The release into the environment can be expected to be mainly into the water compartment, as the substance has a low Henry's law constant (0.0083 Pa*m3/mol). And as the substance has a low (photo-) stability in air, the exposure of the soil compartment via air is unlikely.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
