Hypochlorite laundry detergents

Lithium hypochlorite is used in I I laundry detergents and I I dry laundry bleaches. Like sodium hypochlorite, it does not precipitate soaps and other anionic detergents. However, lithium hypochlorite is an expensive source of available chlorine and not much is used for bleaching. Its principal use is as a shocking agent for swimming pool disinfection.

The largest use of calcium hypochlorite is for water treatment. It is also used for I I and household disinfectants, cleaners, and mildewcides. Most of the household uses have been limited to in-tank toilet bowl cleaners. In areas where chlorine cannot be shipped or is otherwise unavailable, calcium hypochlorite is used to bleach textiles in commercial laundries and textile mills. It is usually first converted to sodium hypochlorite by mixing it with an aqueous solution of sodium carbonate and removing the precipitated calcium carbonate. Or, it can be dissolved in the presence of sufficient sodium tripolyphosphate to prevent the precipitation of calcium salts. However, calcium hypochlorite is not usually used to bleach laundry and textiles because of problems with insoluble inorganic calcium salts and precipitation of soaps and anionic detergents as their calcium salts. 

Controlled chlorination of cyanuric acid results in the formation of di- and tri-chloroisocyanuric acids containing more than 90% available chlorine, which are used in dishwashing detergents and industrial and commercial laundries for their effective bleaching and disinfecting properties. They can be dry-packaged for domestic use and compete with the commonly used sodium hypochlorite. 

Chlorinated trisodium phosphate was introduced in 1928, about the same time as calcium hypochlorite. It is a crystalline complex of hydrated trisodium orthophosphate and sodium hypochlorite with an approximate formula of (Na3P04 11H20)4 NaOCl. It also contains other phosphate salts and sodium chloride. Chlorinated trisodium phosphate is still used in commercial laundries and disinfectant cleaners. In other products, such as powdered abrasive cleansers and automatic dishwash detergents, it has been largely replaced by chlorinated isocyanurates to reduce cost, improve performance, or comply with phosphate restrictions. 

Mildly alkaline solutions of ordinary laundry soaps develop a protective coating on zinc and its alloys. They are satisfactory for both warm and cold applications. Detergent solutions are more corrosive however, the better grades include inhibitors, which reduce corrosion to allow reasonably satisfactory service for zinc alloys. Strong alkalies (e.g., hypochlorite bleach solutions) or acid solutions (e.g., Harpic, which contains trisodium hydrogen disulfate) are to be avoided. 

Although it may deliver the same benefit to the laundry, sodium hypochlorite bleach is also used in some European countries, mostly in northern Europe (from France to Scandinavia), to disinfect and deodorize household hard surfaces. Whereas detergent and hot-water cleaning produce limited reduction in microbial contamination, sodium hypochlorite has been proven to provide a substantial reduction in bacterial contamination in the home [27].
