Sodium Carbonate and Sodium Bicarbonate REACH Consortium

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.
