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.

1-52. (canceled)
A composition comprising:
- (a) an anionic surfactant or a mixture of anionic surfactants, wherein the anionic surfactant or at least one anionic surfactant of the mixture comprises sodium trideceth sulfate,
- (b) at least one alkanolamide,
- (c) at least one electrolyte,
- (d) at least one benefit agent, and
- (e) water,
- wherein the composition possesses non-Newtonian shear thinning properties and a stable viscosity under at least one freeze/thaw cycle and is capable of suspending water-insoluble particles or partially insoluble components;
- and
- further wherein the initial viscosity of the composition is equal to or greater than 3,000 cps.

A stable, multi-phase personal care formulation comprising a composition, wherein said composition comprises, based on the weight of the composition:
- (a) from about 5% to about 30% of an anionic surfactant or a mixture of anionic surfactants, wherein the anionic surfactant or at least one anionic surfactant of the mixture comprises sodium trideceth sulfate,
- (b) from about 2% to about 10% of at least one alkanolamide,
- (c) from about 1% to about 15% of at least one electrolyte,
- (d) at least one benefit agent, and
- (e) water,
- wherein the composition possesses non-Newtonian shear thinning properties and a stable viscosity under at least one freeze/thaw cycle and is capable of suspending water-insoluble particles or partially insoluble components;
- and
- further wherein the initial viscosity of the composition is equal to or greater than 3,000 cps.
