Fragrance and Dye

• Fragrance is added to the scouring powder to improve its scent and to cover up any chemical odor. Colgate-Palmolive doesn't specify what type of fragrance is used. The dye is also unnamed but is included to give the Ajax its clean white color.
  
  

Calcium Carbonate

• Calcium carbonate, also known as monocalcium carbonate, is used in Ajax as a cleaning agent. It's also used in a wide range of other products, from arts and crafts putties to personal care items, including toothpastes and makeup. Ajax is made from limestone, which is heated and then mixed with water. Carbon dioxide is added and produces calcium carbonate, which is then dehydrated to form a powder.
  
  

Sodium Dodecylbenzenesulfonate

• Sodium dodecylbenzenesulfonate, sometimes called Sodium dodecyl benzene sulfonate, is a second cleaning agent in Ajax cleaner. Among other things it's used in car waxes and other auto products, as well as many detergents and a few soaps. It can be dangerous if inhaled or if you get it in your eyes. While prolonged contact with the skin can cause some irritation, it doesn't often cause allergic reactions, which are the usual causes of injury by the use of detergents.
  
  

Trichlorocyanuric Acid

• Trichlorocyanuric acid (TCCA) is used as a stain remover in Ajax cleaners. It's a solid white powder. It is corrosive and, if mixed with acids or acid cleaners, it can release hazardous chlorine gas. It's also used to control bacteria in swimming pools.
  
  

Hazards

• Ajax scouring powder is an eye irritant and should immediately be flushed out with water, but it shouldn't cause any permanent damage. If mixed with ammonia, as well as other cleaning products, it may release harmful fumes. You shouldn't use other cleaners in conjunction with Ajax. Inhaling too much of the dust can irritate your respiratory system.
