Process for making a magnesium linear alkyl benzene sulphonate anionic detersive surfactant flake

A process for making a magnesium linear alkyl benzene sulphonate anionic detersive surfactant flake, wherein the process comprises the steps of:

• (a) obtaining a magnesium linear alkyl benzene sulphonate anionic detersive surfactant liquid,
• wherein the liquid comprises from about 30 wt % to about 90 wt % solid material and from about 10 wt % to about 70 wt % water,
• wherein the solid material comprises from greater than about 50 wt % to about 100 wt % linear alkyl benzene sulphonate anionic detersive surfactant,
• and wherein the linear alkyl benzene sulphonate anionic detersive surfactant comprises from about 70 wt % to about 100 wt % magnesium linear alkyl benzene sulphonate anionic detersive surfactant;
• (b) contacting the liquid to a heatable surface;
• (c) drying the contacted liquid on the heatable surface;
• and
• (d) removing the dried contacted liquid from the heatable surface to form the magnesium linear alkyl benzene sulphonate anionic detersive surfactant flake, wherein the magnesium linear alkyl benzene sulphonate anionic detersive surfactant flake comprises from greater than about 50 wt % to about 100 wt % linear alkyl benzene sulphonate anionic detersive surfactant, and wherein the linear alkyl benzene sulphonate anionic detersive surfactant comprises from about 70 wt % to about 100 wt % magnesium linear alkyl benzene sulphonate anionic detersive surfactant.
