Our sulphur dioxide is manufactured using extra-pure (99.95%) liquid sulphur obtained from desulphurisation in the oil-refining industry. The manufacture of our Sulphur Dioxide is not based on processing contaminated residual acids.

The production process entails burning liquid sulphur to produce gaseous SO₂ which is then liquefied.

This produces a final product of ultra-pure quality and is suitable for use in food applications.
