Summary of Classification and Labelling
Notified classification and labelling
General Information
EC / List no.

EC: European Community number/ List no.: List number assigned by ECHA.

List Numbers are purely technical identifiers for processing a submission via REACH-IT. More information: https://echa.europa.eu/information-on-chemicals/registered-substances/information

Name CAS Number
The CAS number associated with this substance in the EC Inventory and/or REACH-IT is reported here. In some cases, e.g. for differently hydrated forms of the same substance, alternative CAS numbers have been notified. In those cases, the additional CAS numbers are published in the column “additional notified information” below.
231-836-6 Sodium chlorite 7758-19-2

Notified classification and labelling according to CLP criteria
Classification Labelling Specific Concentration limits, M-Factors Notes Classification affected by Impurities / Additives

This check appears when a notifier has indicated that an impurity or an additive present in the substance impacts the notified classification. ECHA cannot reveal the identity of the impurity/additive or determine the exact impact it has on the classification.

Additional Notified Information

State/form: The notified state/form of the substance for all notifications classifying in this manner is reported under this link. Additional CAS number(s): Occasionally, a notification contains a different CAS number than the one reported under the general information section above. In those cases, all different notified CAS numbers associated with the aggregated classification are reported under this link. IUPAC name(s): Publicly available IUPAC names from all notifications classifying in this manner are reported under this link.

Number of Notifiers

This number indicates how many companies notified this classification. All members of a REACH registration joint submission and all participants in a group of manufacturers/importers who notified are counted. The grouping is done automatically with no manual verification.

Joint Entries

This check appears when a classification comes from a lead dossier of a REACH registration joint submission. When a member submits a classification separately under Article 11(3) of REACH (opt-out), this classification is displayed separately and not marked as a joint entry.
