Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Sodium chlorate is highly soluble in water (95.7 g/100 ml at 20°C). Sodium chlorate in aqueous solutions is known for its chemical stability under environmental conditions (Urbanski 1998).

Based on the chemical structure it is expected that sodium chlorate is resistant to hydrolysis.Due to its chemical structure, sodium chlorate is considered as stable in sterile water whatever the pH is. There are no relevant metabolites, degradation or reaction products that necessitate studies to answer this point.

Sodium chlorate is rapidly biodegradable only under anaerobic conditions. Studies on the hydrolysis as a function of the pH are therefore not required.
