Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The likely environmental fate of the substance has been assessed based on the substances physico-chemical properties and relevant available study data (hydrolysis as a function of pH, ready biodegradation, adsorption coefficient).

The substance is highly water soluble (30.5 g/L) and has a very low octanol/water partition coefficient (log10Pow 0.491), indicating that the substance will predominately stay in the aquatic environment. The substances low adsorption coefficient (log10Koc) <1.25 indicates that the substance has low potential for adsorption to sediments and soils and is therefore not likely to partition from the aquatic compartment into the sediment or soil compartments.

Therefore the predominate environmental fate pathway is considered to be the aquatic environment.

The substance is not readily biodegradable (14% degradation after 28 days) based on the results of a "Ready Biodegradability CO2 Evolution Test (OECD Guideline No 301B)".

The substance was determined to be hydrolytically stable at pH 4, 7 and 9 based on the results of a "Hydrolysis as a function of pH" study. The estimated half-life at 25°C at pH 4, 7 and 9 (and therefore environmentally relevant pH's) has been determined to be greater than 1 year.

Based on these results the substance is considered to have potential to persist in the aquatic environment.

Further biodegradation in soils and sediments is considered to be unnecessary to assess, as the substance is not anticipated to accumulate in these compartments.

Although persistent in the aquatic environment, the substances log10Pow (0.491) indicates that the substance has very low potential for bioaccumulation in aquatic organisms.
