Justification for data waiving:
the study does not need to be conducted because the substance is inorganic

Description of key information

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.

Key value for chemical safety assessment

Additional information

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.

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.
