Abstract:
A packaged product of a stable, extrudable, multiphase liquid cleansing composition, comprising:at least one aqueous lamellar structured phase and at least one isotropic phase which abuts said at least one lamellar phase; a surfactant selected from the group consisting of amphoteric, zwitterionic, or a mixture thereof; an anionic surfactant in the concentration range of about 3 to 40 wt. % in each of said lamellar and said isotropic phase; a lamellar structurant present in said lamellar phase of said liquid composition, selected from the group consisting of fatty acids, fatty esters, or trihydroxystearin, wherein said lamellar phase contains about 5% to 70% by wt. of oil/emollient particles and wherein said isotropic phase contains at least about 3% by wt. of surface active material; each of said lamellar phases having a low shear viscosity value above about 80 K cps at 25Â° C.; and each of said isotropic phases having a low shear viscosity value above about 15 K cps at 25Â° C.
