Abstract
A free-flowing surfactant composition comprising at least one anionic surface-active agent, an alkanolamide, an electrolyte, and water is described. In particular, the composition is a surfactant composition that has free-flowing non-Newtonian shear thinning properties and the ability to suspend components and is stable under at least one freeze/thaw cycle.
