Sodium Carbonate and Sodium Bicarbonate REACH Consortium

The manufacturers of sodium carbonate and bicarbonate have joined efforts for their REACH compliance activities and have launched the Soda Ash REACH consortium.

Consortium description

To prepare a consistent REACH registration dossier, the secretariat of the Soda Ash REACH consortium is handled by ReachCentrum.

The consortium members span over a large spectrum of the European chemicals industry and include members from ESAPA - the European Soda Ash Producers Association.

Substances covered

The substances to be registered under the REACH legislation by December 2010 and covered in the Soda Ash REACH consortium are:

Substance name EC Number CAS Number Other identifiers Description Tonnage band Analytical Methods
Sodium carbonate 207-838-8 497-19-8 Disodium carbonate mono-constituent substance > 1000 t/a Analytical
Sodium bicarbonate 205-633-8 144-55-8 Sodium hydrogen carbonate mono-constituent substance > 1000 t/a Analytical

The Substance Identification Profile (SIP) - anhydrous basis - is supporting the substance sameness discussions in SIEFs. The Soda Ash consortium is using this tool to describe the substance to the best of their knowledge.

Sodium Carbonate and Sodium Bicarbonate Uses

The Soda Ash REACH consortium prepared a Chemical Safety Report for Sodium Carbonate, covering a broad list of uses through various Exposure Scenarios. Downstream users of sodium carbonate are encouraged to verify if their product category, process category and environmental release category of their uses are included. If not, please inform your supplier. It is also recommended to check if the proposed risk reduction measures are appropriate.

Downstream users which have additional specific information about operational conditions or risk reduction measures can contact their supplier. In this way the information can be included in the Chemical Safety Report and the extended Safety Data Sheet.

The Sodium Bicarbonate is not a classified substance. Therefore, no Chemical Safety Assessment and no Exposure Scenarios are needed, as described in the document Sodium Bicarbonate Uses for Downstream Users.

Membership

The Soda Ash REACH consortium structure includes a Steering Committee, a Technical Committee and the consortium secretariat managed by ReachCentrum. The Soda Ash consortium is open to manufacturers/ importers/ only representatives as defined in the REACH Regulation of the substance on its own, in preparations or in articles and that are subject to the registration requirements pursuant to the REACH Regulation, or Affiliates thereof. Membership is open to any applicant fulfilling the membership criteria. Downstream users and other data holders are invited to play an active role in the work of the consortium.
