Packaging and delivery
•
Packaging in bulk bags 1.1 metric T on pallet.
Storage
•
Sodium carbonate is particularly sensitive to
hydration with caking when exposed to
humidity.
After two months of storage, there are risks of
caking. Store in cool and dry place.
The stacking of pallets is inadvisable.

Uses
The chemical properties of sodium carbonate
(source of carbonate, alkalinity, melting
properties) allow its use in a lot of industries.
