1. A moldable solid washing agent composition comprising a starch-based polymer, a polyol, and a surfactant, wherein the starch-based polymer is comprised in an amount of more than 0 wt % and less than 20 wt % based on the total weight of the composition,
wherein the content of the polyol is 0.1-10 wt % based on the total weight of the composition,
wherein the surfactant is a nonionic surfactant,
wherein the content of the nonionic surfactant is 0.1-4 wt % based on the total weight of the composition,
wherein the starch-based polymer is one or more selected from the group consisting of corn starch, dextrin, hydroxypropyl starch phosphate, and sodium polyacrylate starch,
wherein the polyol is one or more selected from the group consisting of glycerin, butylene glycol, propylene glycol, dipropylene glycol, polyethylene glycol, and sorbitol,
wherein the nonionic surfactant is one or more selected from the group consisting of an alkanolamide-based surfactant, an amine oxide-based surfactant, a mono- or polysaccharide-based surfactant, a fatty acid ethoxylate-based surfactant, a PEG-based surfactant, a polyethylene oxide-polypropylene oxide copolymer, a polyethylene oxide-polypropylene oxide-polyethylene oxide triblock copolymer, polyvinylpyrrolidone, a polyoxyethylene alkyl ether-based surfactant, and a sorbitan-based surfactant, and
wherein an article can be molded from the composition by applying a pressure of 5-100 mbar to said moldable solid washing agent composition at room temperature and atmospheric pressure.
