Automatic Dishwasher Detergent

This formulation features Van Gel ES. magnesium aluminum silicate, as a suspending agent and rheology modifier. The sodium hypochlorite functions as a disinfectant, cleaning agent and bleach. Sodium metasilicate adjusts the formula pH. The phosphate blend provides detergency and the surfactants contribute excellent rinsability.

About 264,000 metric tons of elemental capacity is available in North America, plus another 79,000 t (P equivalent) of purified wet phosphoric acid (14). About 85% of the elemental P is burned to P2 5 hydrated to phosphoric acid. Part of the acid (ca 21%) is used direcdy, but the biggest part is converted to phosphate compounds. Sodium phosphates account for 47% calcium, potassium, and ammonium phosphates account for 17%. Pinal apphcations include home laundry and automatic dishwasher detergents, industrial and institutional cleaners, food and beverages, metal cleaning and treatment, potable water and wastewater treatment, antifree2e, and electronics. The purified wet acid serves the same markets. 

The use of chlorinated trisodium phosphate is declining. It has been largely replaced by chlorinated isocyanurates in powdered abrasive cleansers and automatic dishwash detergents to reduce cost, improve performance, or comply with restrictions on the use of phosphates. Some chlorinated trisodium phosphate is stiU used in commercial laundries and in disinfectant cleaners. 

Phospha.tes, Pentasodium triphosphate [7758-29-4] sodium tripolyphosphate, STPP, Na P O Q, is the most widely used and most effective builder in heavy-duty fabric washing compositions (see also Phosphoric acid and phosphates). It is a strong sequestrant for calcium and magnesium, with a p c of ca 6, and provides exceUent suspending action for soils. Because of its high sequestration power, it also finds extensive appHcation in automatic-dishwashing detergents. Sodium tripolyphosphate forms stable hydrates and thus aids in the manufacture of crisp spray-dried laundry powders.

Nonionic surfactants are also used in substantial amounts in laundry detergents and in automatic dishwashing detergents, both applications reflecting in particular their generally lower sudsing characteristics than the anionics. Commercially important examples uf the nonionics include the alkyl ethoxylates, the ethoxylated alkyl phenols, the fatly acid ethanol amides, and complex polymers of ethylene oxide, propylene oxide, and alcohols.

Lye is used in household drain cleaners, ammonia, automatic dishwasher detergents, Clinitest tablets, oven cleaners, and bleaches. It is also used in the manufacture of soaps and cleaners and in chemical synthesis. 

Liquid automatic dishwasher detergents (LADDs) were first introduced to the U.S. and European markets in 1986. Prior to that, all dishwasher detergents were in powder form. LADDs have slowly gained popularity since their introduction. At the same time there has been an increase in the number of households with dishwashers, especially in the U.S. and Europe. By the early 2000s about half of U.S. households had dishwashers. LADDs account for about 40% of the dishwasher detergent market 40% is accounted for by the powder form and 20% by the new unit-dosed form.
