Our sodium hexametaphosphate (SHMP) holds the formula Na6P6O18. An inorganic polyphosphate salt, it is commonly used as a food additive, water treatment chemical, deflocculant and tooth whitening agent.

We manufacture, supply and distribute SHMP to meet the requirements of many industries across the UK.


Food Additives

- Emulsifier: commonly used in canned milk, cheese powders, imitation cheese, roast beef, breakfast cereals, ice cream, packaged egg whites and more to maintain texture.

- Sequestrant: extends shelf life, enhances flavour and prevents turbidity in fruit juices and carbonated beverages.

- Stabiliser: can stabilise pigments in canned beans, vegetables and fruits.

Industrial Ingredients

- One use for SHMP is as a deflocculant in clay processing, and for preparing solutions for the production of ceramics.

Cleaning Chemicals & Detergents

- Water softening & detergents: sodium carbonate can be added to SHMP to raise its pH, which produces a number of water softening and detergent products.

Water Treatment

- SHMP is a sequestrant that can inhibit corrosion, metal leaching and biofilm formation in pipes. It can chelate certain metal oxides.


- Personal care: used in toothpaste formulations as a tooth whitening agent for tartar and stain prevention, and as a chelating and masking agent in other cosmetic products.
