Description of key information
Waiving of study:
For a liquid such as the aqueous solution of sodium hypochlorite, the primary value for ease of ignition is the flash point. No flash point was observed up to 111°C. Thus the substance is not regarded as flammable.
A test on flammability in contact with water does not need to be conducted as the substance is marketed and used in aqueous solution and experience in handling and use gives no indications that the substance reacts with water.
A test on pyrophoric properties does not need to be conducted as experience in handling and use gives no indications that the substance ignites or reacts with air.
Key value for chemical safety assessment
- Flammability:
- non flammable

Justification for classification or non-classification
Based on the results of the flash point study (no flash point observed up to 111°C) and taking into account experience in handling and use together with the provisions laid down in Council Directive 67/548/EEC and CLP, sodium hypochlorite does not have to be classified with respect to flammability.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
