Endpoint:
oxidising liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 7 to 11 July, 2016.
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.21 (Oxidising Properties (Liquids))
Deviations:
no
GLP compliance:
yes (incl. certificate)
Contact with:
other: Fibrous cellulose
Key result
Sample tested:
test mixture 1:1
Parameter:
mean pressure rise time
Result:
25.53 s
Sample tested:
test mixture 1:1
Remarks:
65 % nitric acid: cellulose
Parameter:
mean pressure rise time
Result:
4.59 s
Interpretation of results:
GHS criteria not met
Conclusions:
The sample of Sodium Chlorite Solution 25.6 % (w/w) was found to have a mean pressure rise time greater than that observed for the nitric acid reference sample. The sample was therefore not considered to be an oxidising liquid.
Executive summary:

A physicochemical test was conducted in order to determine the oxidising properties of an aqueous solution of sodium chlorite 25.6 % w/w. The test was conducted according to the EEC method A.21 under GLP conditions. The test item was found to have a mean pressure rise time greater than that observed for the nitric acid reference sample. The sample was therefore not considered to be an oxidising liquid.

Description of key information

Weight of evidence:

Handbooks peer reviewed:
Sodium chlorite is a strong oxidizing agent. No data on the test method.
Sodium chlorite is a powerful oxidizing.
Publication: 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. No data provided on the method.

Aqueous solution (25.6% w/w):

Key study: Test method according to EU A.21. under GLP conditions. A solution of 25.6 % w/w sodium chlorite was not considered a oxidising liquid.

Key value for chemical safety assessment

Oxidising properties:
oxidising

Additional information

Sodium chlorite (solid) is a strong oxidizing agent

Aqueous solution: A 25.6 % w/w solution of sodium chlorite was not a oxidising liquid.

Justification for classification or non-classification

Based on the available data, sodium chlorite is classified as oxidizing solid Category 1 in accordance with CLP Regulation (EC) no. 1272/2008
