Calcium Chloride REACH Consortium

The manufacturers of Calcium Chloride have joined efforts for their REACH compliance activities and have launched the Calcium Chloride REACH Consortium.

Consortium description

The REACH Registration dossier was originally submitted in 2010. The Lead Registrant for Calcium Chloride is Solvay Chimica Italy S.p.A and the secretariat of the Calcium Chloride 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. Calcium chloride is produced by several processes including the Ammonia-Soda process and reaction of limestone with hydrochloric acid among other methods. Calcium chloride finds use in a vast number of applications within many industrial, professional and consumer sectors. In 2010, the dossier was originally compiled with information primarily owned by the member companies. At that time the member companies also jointly decided on the common uses to be included in the CSR. In 2020, the dossier was spontaneously updated in function of the Art. 22 requirements or REACH. Again this action was performed by the group of companies active within the Calcium Chloride Consortium. The dossier was upgraded to the latest applicable IUCLID version, a new literature search was performed and the dossier was updated with the new relevant hazard information. The exposure and risk assessment was fully reviewed, slightly re-organized (see section ‘Substances covered’ for overview of uses covered) and generated within Chesar.

Substances covered

The substance to be registered under the REACH legislation by December 2010 and covered in the Calcium Chloride REACH Consortium is:

Substance CAS Number EC Number Description Tonnage band
Calcium Chloride 10043-52-4 233-140-8 mono-constituent substance > 1000 t/a


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

The uses covered by the dossier can be found here 


The Calcium Chloride REACH consortium structure includes a Steering Committee, a Technical Committee and the consortium secretariat managed by ReachCentrum.

The Calcium Chloride 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.

Current members of the Calcium Chloride REACH Consortium are:

  • Caffaro Brescia srl
  • Chimcomplex SA Borzesti
  • CIECH Soda Polska S.A.
  • Kaustik Europe B.V.
  • Macco Organiques, s.r.o.

Status of REACH Registration

Calcium chloride has been successfully submitted early October 2010-12-08.

Classification and Labelling

Calcium chloride is included in Annex VI of EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008 and is classified as Eye Irrit. 2 (Hazard statement: H319: Causes serious eye irritation). However, the results of the available studies suggest that anhydrous calcium chloride should be classified as Eye Irrit. 1 (Hazard statement: H318: Causes serious eye damage). For calcium chloride hydrates, classification as Eye Irrit. 2 (Hazard statement: H319: Causes serious eye irritation) is still considered applicable. Nevertheless, in accordance with Article 4, point 3 of EU Classification, Labeling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008, if a substance is subject to harmonised classification and labelling in accordance with Title V through an entry in Part 3 of Annex VI, that substance shall be classified in accordance with that entry, and a classification of that substance in accordance with Title II shall not be performed for the hazard classes or differentiations covered by that entry. Based on this, classification of calcium chloride as Eye Irritant Category 2, H319 shall be followed by the registrant in this dossier.

Calcium Chloride is not classified for environmental hazards or physicochemical properties.
