Combined stable cationic and anionic surfactant compositions

An aqueous free flowing structured surfactant composition, comprising:

• (a) from 4% to 25% by weight of at least one anionic surfactant comprising a trideceth sulfate or a salt thereof,
• (b) from 2% to 6% by weight of at least one cationic surfactant of formula (I):
• wherein:
• R1, R2, R3, and R4 comprise hydrogen, an organic group, or a combination thereof, provided that at least one of R1, R2, R3, and R4 is not hydrogen, and
• X− is an anion,
• (c) optionally, an amphoteric/zwitterionic surfactant, a nonionic surfactant, or a mixture thereof, and
• (d) water,
• wherein the total amount of all surfactants in the composition ranges from 8% to 30%, and
• further wherein the composition:
• is visually semi-translucent, translucent, or opaque,
• 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 and partially insoluble components.

An aqueous free flowing structured surfactant composition, comprising:

• (a) from 4% to 25% by weight of at least one anionic surfactant comprising a trideceth sulfate,
• (b) at least one cationic surfactant comprising myristl trimonium bromide,
• (c) an amphoteric/zwitterionic surfactant, a nonionic surfactant, or a mixture thereof, and
• (d) water,
• wherein the at least one anionic surfactant and the at least one cationic surfactant are present in a combined amount such that the composition:
• is visually semi-translucent, translucent, or opaque, and
• possesses non-Newtonian shear thinning properties and a stable viscosity under at least one freeze/thaw cycle.
