CA 2295781

A granular detergent product is made by contacting a liquid binder and a solid neutralising agent. The binder has an acidic component comprising an anionic surfactant acidic precursor and an inorganic acid. The inorganic acid is at least 2.5 % by weight of the acidic component. The neutralising agent and at least some of the binder are granulated in a low-shear granulator, especially a gas fluidisation granulator.
