Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The potential for bioaccumulation of the substance is solely driven by lipophilicity as the substance is not surface active or ionisable at environmental pH (pH 4 – 9). Thus, this endpoint can be waived on the basis of low octanol-water partition coefficient. Based on the low log Kow of the substance, NMMO is not expected to have any potential for bioaccumulation. This was confirmed by a study of Lackner (1991), in which a BCF of < 10 L/kg ww was obtained for rainbow trout and zebra mussel (no NMMO detected in whole organisms/tissues).
