Sodium Carbonate Monohydrate (Na2CO3.H2O)
With 25% water of crystallisation, Sodium Carbonate Monohydrate is the most stable species of Sodium Carbonate. It has all of the properties of Sodium Carbonate, coupled with cold water solubility.
Sodium Carbonate Decahydrate starts to lose its water content above 33oC. As it cools, the product can therefore set hard; although it is still water soluble, it's more difficult for the end user to use. The Sodium Carbonate Monohydrate granule is stable to 100oC before losing its water so is sometimes referred to as 'heat stable soda crystals'; it is an ideal export grade concentrated soda crystals product. It is also ideal as an ingredient in low temperature laundry or dishwash formulations where the higher alkalinity of this product compared to Sodium Sesquicarbonate is important.
Recent advances in our crystallisation process allow us to produce Sodium Carbonate with any level of water of crystallisation between 25% and 60%. Please enquire for any specific properties you are trying to achieve.
Other additives such as Polycarboxylates and Surfactants can also be incorporated to this product.
