Abstract
An aqueous, low pH structured surfactant composition, contains, based on 100 parts by weight of the composition, from about 3 parts by weight to about 40 parts by weight of one or more anionic surfactants selected from anionic phosphate ester surfactants, anionic sulfonate surfactants, and anionic carboxylate surfactants, wherein the composition exhibits a pH of less than about 5, exhibits shear-thinning viscosity, and is capable of suspending water insoluble or partially water soluble components.
Claims17
An aqueous, low pH structured surfactant composition, comprising, based on 100 parts by weight of the composition, from about 3 parts by weight to about 40 parts by weight of one or more anionic surfactants selected from anionic phosphate ester surfactants, anionic sulfonate surfactants, and anionic carboxylate surfactants, wherein the composition exhibits a pH of less than about 5, exhibits shear-thinning viscosity, and is capable of suspending water insoluble or partially water soluble components.
An aqueous, low pH composition, comprising:
- a continuous structured surfactant phase, said structured surfactant phase comprising water and one or more anionic surfactants selected from anionic phosphate ester surfactants, anionic sulfonate surfactants, and anionic carboxylate surfactants, and exhibiting shear-thinning viscosity, and
- one or more water insoluble or partially water soluble components suspended in the structured surfactant phase,
- wherein the composition exhibits a pH of less than about 5.
An aqueous, low pH composition, comprising at least two at least substantially distinct phases, wherein at least one of such phases is a structured surfactant phase that comprises water and one or more anionic surfactants selected from anionic phosphate ester surfactants, anionic sulfonate surfactants, and anionic carboxylate surfactants, and exhibits shear-thinning viscosity and wherein the composition exhibits a pH of less than about 5.
