The largest market for phosphonates is in domestic and industrial detergents. Phosphonates ensure detergents wash effectively, enabling consumers to use lower doses. Manufacturers also utilise phosphonates to create detergents with a lower chemical load.

In detergents, phosphonates:

• Prevent mineral deposits (for example, scale) in washing machines and dishwashers, and on the clothes and tableware being washed. Phosphonates modify the properties of calcium and magnesium salt deposits in hard water, which stops these deposits from adhering to surfaces. This increases the lifespan of the machine and maintains the eco-efficiency of the appliance
• Reduce re-deposition of dirt on cleaned textiles
• Stabilise peroxide bleaches
• Contribute to the removal of stains in bleach-free detergents
• Protect the fragrances and natural (bio-derived) ingredients in detergents from oxidation
• Prevent colours from fading.

Other applications

The same phosphonates that are found in detergents can be utilised in applications such as:

• Ceramic, cement, and concrete production
• Cosmetics and shampoos
• Drinking water production, desalination systems, and purification of water membranes
• Heating and cooling circuits
• Industrial and large-scale cleaning applications
• Medical drugs used for the treatment of conditions such as osteoporosis, vascular calcification, and bone cancer
• Production processes for metal finishing, oil and petroleum, paint, paper, pulp, and textiles.
