1. A water-soluble refill dose article for forming a cleanser comprising:
a water-soluble film defining a single closed internal space in which a liquid concentrated cleanser composition is encapsulated, the liquid concentrated cleanser composition comprises:
a rheology modifier selected from the group consisting of carbohydrate gums, swellable acrylate polymers, cationic guar, cationic modified cellulose, synthetic cationic polymer, high molecular weight polyethylene glycols, superabsorbent polymers, and combinations thereof;
a first surfactant comprising an anionic surfactant 10% wt/wt to 99% wt/wt of the liquid concentrated cleanser composition, the first surfactant being selected from the group consisting of ammonium lauryl sulfate, ammonium laureth sulfate, triethylamine lauryl sulfate, triethylamine laureth sulfate, triethanolamine lauryl sulfate, triethanolamine laureth sulfate, monoethanolamine lauryl sulfate, monoethanolamine laureth sulfate, diethanolamine lauryl sulfate, diethanolamine laureth sulfate, lauric monoglyceride sodium sulfate, sodium lauryl sulfate, sodium laureth sulfate, potassium laureth sulfate, sodium lauryl sarcosinate, sodium lauroyl sarcosinate, potassium lauryl sulfate, sodium trideceth sulfate, sodium methyl lauroyl taurate, sodium lauroyl isethionate or methyl isethionate, sodium lauroyl lactylate, sodium laureth sulfosuccinate, sodium lauroyl sulfosuccinate, sodium tridecyl benzene sulfonate, sodium dodecyl benzene sulfonate, sodium olefin sulfonate, sodium decyl sulfate, olivoil avenate, disodium coco-glucoside citrate, ammonium ether sulfate, laureth-5 carboxylic acid, potassium olivoyl hydrolyzed oat protein, sodium cocoyl glutamate, an aliphatic sulfonate, and mixtures thereof;
a first alkaline substance comprising an ethoxylated amine present as a stabilizing amount to prevent the rheology modifier from increasing the viscosity before water dissolves the water-soluble film;
about 10% or less by wt/wt water; and
about 20% or less by wt/wt glycol;
wherein the article has an article to water ratio in a range of 1:1 to 1:20 and, upon addition of the article and water of a preselected cleanser volume, a cleanser having a viscosity within a range of 2000 cps to 50,000 cps is formed.
