Origin and properties of ingredients

Zeolite A (sodium aluminium silicate), the main ingredient of the softener, is made from the easily accessible raw materials water glass and sodium aluminate. This silicate intercepts the water hardness-forming calcium and magnesium ions according to the principle of ion exchange and thus prepares soft water for washing with soap detergent. Soda, made from lime and common salt, forms a chemical compound with the lime in the water and thus removes some of the water hardness-forming substances from the washing water. Citrate, the salt of citric acid, which is obtained by fermenting sugar-containing by-products such as molasses, binds lime to itself, especially at low temperatures.
