Phosphate builders for detergents

Summary

In summary, the chemistry of the preparation of sodium and potassium polyphosphates, and the properties of importance to their use as detergent builders, such as hydrolysis, hydration rates and solubilities have been discussed. The properties of granular Na⁵P₃O₁₀, such as density, particle size, frangibility and absorptivity, were discussed in connection with their use in the dry blending and tabelting of detergent products.
