1. A method of preparing a solidified surfactant composition comprising:
adding a liquid surfactant comprising one or more of an amine oxide, a betaine, and a sultaine, and a solid binder comprising a natural polymer, urea, a urea derivative, an inorganic salt, an organic salt or a combination thereof to a spray dryer drying device, wherein the solid binder is dissolved with the liquid surfactant in a ratio of between about 1:1 to about 1:30 by actives;
drying the liquid surfactant and binder to form a solidified surfactant composition;
wherein the liquid surfactant is solidified in the solidified surfactant composition, and
wherein the solidified surfactant composition has less than about 5 wt-% water.
