Description of key information

Biodegradation in water: screening tests

Data waiving: In accordance with column 2 of REACH Annex VII, the study does not need to be conducted for inorganic substances.

Sodium chlorite is expected to be rapidly reduced to sodium chloride in the environment, especially in anaerobic conditions.

Biodegradation in water and sediment: simulation tests

Data waiving:In accordance with column 2 of REACH Annex IX, the biodegradation in water and sediment studies (simulation tests) do not need to be conducted since there is no need to investigate further the degradation of the substance and its degradation products.

Data waiving: In accordance with column 2 of REACH Annex IX, the biodegradation studies in soil do not need to be conducted since there is no need to investigate further the degradation of the substance and its degradation products.

 

Additional information

Sodium chlorite is a strong oxidizing agent and under proper reducing conditions is readily reduced to chloride, and to a lesser extent, chlorate. In strong acidic conditions, chlorite can change into chlorine dioxide (from pg. 11, USEPA/OPPTS; Reregistration Eligibility Decision (RED) for Chlorine Dioxide and Sodium Chlorite (Case 4023) p.1 (August 2006) EPA-HQ-OPP-2006-0328-0022/EPA 738-R-06-007.
