1. A method of preparing a solidified surfactant composition comprising:
adding to a drying device:
a liquid anionic surfactant comprising a sodium lauryl ether sulfate surfactant;
a solid binder comprising a polyethylene glycol (PEG); wherein the solid binder is dissolved with the liquid surfactant in a ratio of between about 4:1 to about 1:60 by actives, and
a solid carrier comprising an alpha olefin sulfonate, wherein the carrier and the liquid surfactant are in a ratio of between about 5:1 to about 1:30 by actives;
drying the liquid surfactant and binder and solid carrier to form a solidified surfactant composition;
wherein the drying device comprises a fluidized bed; and
wherein the liquid surfactant is solidified in the solidified surfactant composition, and wherein the solidified surfactant composition has less than about 5 wt-% water.
