A colourless acid with multiple uses in many industries from oil and gas to water treatment. We have the largest phosphoric acid storage facilities in the UK.


  • Lowers pH levels
  • Can be used as both a chelant and dispersing agent 
  • Also used as catalyst in hydration of alkenes to produce alcohols
  • Acts as an electrolyte in phosphoric acid fuel cells

The phosphoric acid we distribute is an 85% strength aqueous solution, holding the formula H3PO4 with a conjugate base of phosphate, PO3−4. It is a colourless solution with no distinctive odour.
