Sodium formaldehyde sulfoxylate, wanda aka sani da ita rongalite, is a white nubby or crystalline powder of organic compounds, chemically named formaldehyde sodium hyposulfite, molecular formula is NaHSO2-CH2O-2H2O, soluble in water, more stable at room temperature, decomposed into sulfite gishiri at high temperature, with strong reducing properties.


The rongalite is based on sodium metabisulphite, which is obtained by the reduction of zinc powder and the addition of formaldehyde in one step.


The reduction and addition of the raw materials are completed in the same kettle and the reaction products are all transformed into products without waste.


In addition to the main product, a chemically pure zinc oxide (99.5 %) is also produced.


The process is characterised by short flow times, stable technical conditions, low investment in equipment and simple operation.


The solution begins to decompose above 60 ()degrees Celsius.


It is usually used as a bleaching agent in industry.
