Sulfamic acid is a white crystalline solid which is non-hygroscopic and stable. Sulfamic acid is a super-efficient agent for descaling. It is used for cleaning a number of domestic appliances and industrial equipment. Sulfamic acid is used as an acidic cleaning agent, usually for ceramics and metals. Sulfamic acid is a safe and powerful acid, which is suitable for descaling applications and acid cleaning.
Sulfamic acid also called as amido sulfuric acid is a white crystalline solid which is non-hygroscopic and stable. It is soluble in formamide and water, and slightly soluble in concentrated sulfuric acid, methanol, acetone, and ether. It is commercially produced from fuming sulfuric acid and urea, and classified as a strong inorganic acid. The sulfamic acid with dilute aqueous solution is stable for longer periods at room temperature. However, a rapid hydrolysis arises at high temperatures. The sulfamic acid is considered as less corrosive to metals compared to other strong acid such as hydrochloric acid. As the sulfamic acid retains a scale solubilizing capacity it is considered ideal for removal of scale from cooling towers, boilers, coils, condensers, heat exchangers and a wide range of cooling and heating systems thereby amassing the efficiency of equipment and plant.

Uses of Sulfamic Acid
As sulfamic acid is super-efficient agent for descaling, it is used for cleaning a number of domestic appliances and industrial equipment. It is used for cleaning heat exchangers, boilers, condensers, descaling toilets, jackets and coils, efflorescence other deposits of mineral deposits, removing excess grout on tiles, etc. It helps remove protein deposits, hard water scale, beer and milk stone, copper corrosion, and light rust. Some other uses of sulfamic acids are listed below.

Sulfamic Acid as a Cleaning Agent
As per Research Dive analyst review, sulfamic acid is used as an acidic cleaning agent, usually for ceramics and metals. Over the last few years sulfamic acid has replaced hydrochloric acid as a remover of the rust. In homes, it is frequently found as a descaling agent in toilet cleaners, and detergents for the removing the lime scale. When compared to other strong and most common strong mineral acids, the sulfamic acid has the needed low toxicity, low volatility, and water descaling properties. It forms water-soluble salts of ferric iron and calcium.
Sulfamic acid provides intrinsic safety and hence it is preferred over hydrochloric acid for household use. Unlike the most common acids, the sulfamic acid does not form chlorine gas if invalidly mixed with hypochlorite based products.

Industrial Applications of Sulfamic Acid
The sulfamates have been used in the design of various types of therapeutic agents such as nucleotide/nucleoside HIV, antibiotics, HIV protease inhibitors (PIs), weight loss drugs, antiepileptic drugs, and anticancer drugs. Sulfamic acid is also used as a chlorine stabilizer in cooling towers and swimming pools.
Sulfamic acid is a safe and powerful acid, which is suitable for descaling applications and acid cleaning. One of the most common use of sulfamic acid is for descaling heating coils and heated vessels in the food handling premises owing to its ability to quickly dissolve hardness deposits without objectionable odors or fumes. Hence, sulfamic acid is considered as the most popular, safe, preferred acid in various industries.
