Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Due to the low log Kow of 0.35 no bioaccumulation is expected in aquatic or terrestrial organisms.
Additional information
The measured log Kow of 0.35 at 20°C (Hansch et al. 1995) indicates a low potential for bioaccumulation. This is confirmed by several publications investigating the test bioaccumulation in several marine (Jung et al. 2001) and freshwater fish (Sills, 1979), as well as in the blue shrimp (Hose et al., 1980). In all studies the BCF was determined to be <1 due to low test item concentrations in the extracted tissues. Hose et al., 1980 observed significant amounts of extractable formaldehyde during longer post-mortem storage up to 72 hours, which were produced biologically due to tissue decomposition. All in all accumulation of the test item from the environment is very unlikely. Consequently, secondary poisoning due to food-chain accumulation can be excluded.
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.
