Sulphamic acid also called sulfamic acid is a white crystalline solid which is stable and non-hygroscopic. It is soluble in water and formamide and slightly soluble in methanol, ether, acetone and concentrated sulphuric acid. It is classified as a strong inorganic acid and is commercially produced from urea and fuming sulphuric acid. At room temperature, dilute aqueous sulphamic acid solution is stable for a long time but rapid hydrolysis occurs at elevated temperatures. It's solution is less corrosive toward metals than other mineral acids like hydrochloric acid. Sulfamic acid possesses a scale solubilising capacity which makes it ideal for removal of scale from boilers, cooling towers, coils, heat exchangers, condensers and a wide range of heating and cooling systems thereby increasing the efficiency of plant and equipment.
Sulphamic acid is used as an acidic cleaning agent, typically for metals and ceramics. It is a replacement for hydrochloric acid for the removal of rust. In households, it is often found as a descaling agent in detergents, cleaners and toilet cleaners for the removal of limescale.
