Notified classification and labelling according to CLP criteria
General Section
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. 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.

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.

Note Title Note Text
Note U When put on the market gases have to be classified as "Gases under pressure", in one of the groups compressed gas, liquefied gas, refrigerated liquefied gas or dissolved gas. The group depends on the physical state in which the gas is packaged and therefore has to be assigned case by case.
Note 5 The concentration limits for gaseous mixtures are expressed as volume per volume percentage.
