A process for preparing a flexible porous dissolvable solid structure article, comprising the steps of: a. preparing a pre-mixture comprising a surfactant, a water soluble polymer, and optionally a plasticizer, wherein said pre-mixture comprises: i. from 15% to 70%, alternatively from 30% to 70%, alternatively from 30% to 60%, alternatively from 32% to 55%, alternatively from 34% to 50%, alternatively from 36% to 45%, solids by weight of the pre-mixture before drying; and ii. a viscosity of from 2,500 cps to 150,000 cps, alternatively from 15,000 cps to 150,000 cps, alternatively from 20,000 cps to 125,000 cps, alternatively from 25,000 cps to 100,000 cps, alternatively from 30,000 cps to 75,000 cps, as measured using a TA Instruments AR500 Rheometer with 4.0 cm diameter parallel plate and 1,200 micron gap at a shear rate of 1.0 reciprocal seconds for a period of 30 second at 23°C; b. heating the pre-mixture, before and during the aeration process, between 40°C and 99°C, alternatively between 50°C and 95°C, alternatively between 60°C and 90°C; c. aerating said pre-mixture by introducing a gas into the pre-mixture to form a wet aerated pre-mixture; d. forming the wet aerated pre-mixture into one or more shapes to formed an aerated wet pre-mixture; e. drying the formed aerated wet pre-mixture in a drying environment, wherein the drying environment is heated to a temperature between 100°C and 150°C, alternatively between 105°C, to 145°C, alternatively between 110°C and 140°C, alternatively between 115°C, and 135°C, such that the pre-mixture is dried within 3 to 90 minutes, alternatively from 5 to 60 minutes, alternatively from 7 to 45 minutes, to a final moisture content from 0.1% to 25% moisture to form the flexible porous dissolvable solid structure article; and f. optionally cutting the flexible dissolvable porous solid structure article. a. preparing a pre-mixture comprising a surfactant, a water soluble polymer, and optionally a plasticizer, wherein said pre-mixture comprises: i. from 15% to 70%, alternatively from 30% to 70%, alternatively from 30% to 60%, alternatively from 32% to 55%, alternatively from 34% to 50%, alternatively from 36% to 45%, solids by weight of the pre-mixture before drying; and ii. a viscosity of from 2,500 cps to 150,000 cps, alternatively from 15,000 cps to 150,000 cps, alternatively from 20,000 cps to 125,000 cps, alternatively from 25,000 cps to 100,000 cps, alternatively from 30,000 cps to 75,000 cps, as measured using a TA Instruments AR500 Rheometer with 4.0 cm diameter parallel plate and 1,200 micron gap at a shear rate of 1.0 reciprocal seconds for a period of 30 second at 23°C; i. from 15% to 70%, alternatively from 30% to 70%, alternatively from 30% to 60%, alternatively from 32% to 55%, alternatively from 34% to 50%, alternatively from 36% to 45%, solids by weight of the pre-mixture before drying; and ii. a viscosity of from 2,500 cps to 150,000 cps, alternatively from 15,000 cps to 150,000 cps, alternatively from 20,000 cps to 125,000 cps, alternatively from 25,000 cps to 100,000 cps, alternatively from 30,000 cps to 75,000 cps, as measured using a TA Instruments AR500 Rheometer with 4.0 cm diameter parallel plate and 1,200 micron gap at a shear rate of 1.0 reciprocal seconds for a period of 30 second at 23°C; b. heating the pre-mixture, before and during the aeration process, between 40°C and 99°C, alternatively between 50°C and 95°C, alternatively between 60°C and 90°C; c. aerating said pre-mixture by introducing a gas into the pre-mixture to form a wet aerated pre-mixture; d. forming the wet aerated pre-mixture into one or more shapes to formed an aerated wet pre-mixture; e. drying the formed aerated wet pre-mixture in a drying environment, wherein the drying environment is heated to a temperature between 100°C and 150°C, alternatively between 105°C, to 145°C, alternatively between 110°C and 140°C, alternatively between 115°C, and 135°C, such that the pre-mixture is dried within 3 to 90 minutes, alternatively from 5 to 60 minutes, alternatively from 7 to 45 minutes, to a final moisture content from 0.1% to 25% moisture to form the flexible porous dissolvable solid structure article; and f. optionally cutting the flexible dissolvable porous solid structure article.
