Water supply worldwide has a very high mineral content hard water, which causes scale deposition, conducing the usage of descalers. Sulphamic acid is a white crystalline solid, stable and non-hygroscopic widely used as an acid cleaning agent, typically for metals and ceramics. It is a better replacement for hydrochloric acid in rust removal.
For cleaning boilers, heat exchangers, condenser jackets and coils, descaling toilets, removing excess grout on tiles, efflorescence and other mineral deposits, sulphamic acid is widely used. It helps remove hard water scales, protein deposits, beer and milk stones, light rust and copper corrosion. It stabilizes chlorine in swimming pools and cooling towers along with its inhibitor properties serving as an efficient penetrant and dispersant to enhance the effectiveness of the acid. In households, it is often found as a descaling agent in detergents, cleaners and toilet cleaners for the removal of lime scales.
Sulfamic acid is used as an acidic cleaning agent, sometimes pure or as a component of proprietary mixtures, typically for metals and ceramics. It is frequently used for removing rust and limescale, replacing the more volatile and irritating hydrochloric acid, which is cheaper. Often a component of household descaling agents or detergents for the removal of limescale. When compared to most of the common strong mineral acids, sulfamic acid has desirable water descaling properties, low volatility, and low toxicity. It forms water-soluble salts of calcium and ferric iron.
It also finds applications in the industrial cleaning of dairy and brewhouse equipment. Although it is considered less corrosive than hydrochloric acid, corrosion inhibitors are often added to the commercial cleansers of which it is a component. It can be used for descaling home coffee and espresso machines and in denture cleaners.
Other uses include Catalyst for esterification process, Dye and pigment manufacturing, Herbicide, Coagulator for urea-formaldehyde resins, Ingredient in fire extinguishing media. Sulfamic acid is the main raw material for ammonium sulfamate which is a widely used herbicide and fire retardant material for household product, Pulp and paper industry as a chloride stabilizer, Synthesis of nitrous oxide by reaction with nitric acid, The deprotonated form (sulfamate) is a common counterion for nickel(II) in electroplating, Separation of nitrite ions from mixture of nitrite and nitrate ions( NO3-+ NO2-), Silver polishing.
Sulfamic acid is preferable to hydrochloric acid in household use, due to its intrinsic safety. If erroneously mixed with hypochlorite based products such as bleach, it does not form chlorine gas, whereas the most common acids would; the reaction (neutralization) with ammonia, produces a salt.
