According to the present invention, an externally disintegrating solid cleanser containing algin, calcium sulfate, magnesium oxide, diatomite, corn starch, a surfactant, additives, and water in the form of a discontinuous hydrogel-powder composite, and a method for producing same are provided. The algin and calcium sulfate, together with water, form a discontinuous hydrogel and act as a binder for powder particles, the corn starch is gelatinized into an adhesive starch by water and acts as an adhesive for the powder particles, and the discontinuous hydrogel and the adhesive starch, together with the powder particles, can form a discontinuous hydrogel-powder composite having a three-dimensional structure. The externally disintegrating solid cleanser according to the present invention not only has excellent handling properties and ease of use due to having high water resistance, impact resistance, and externally disintegrating properties, but can also be molded into a one-time usage amount so that none of the product is wasted, and has excellent cleansing power so that deep cleansing of even pores is possible and double cleansing is not required.La présente invention concerne un nettoyant solide à désintégration externe contenant de l'algine, du sulfate de calcium, de l'oxyde de magnésium, de la diatomite, de l'amidon de maïs, un tensioactif, des additifs et de l'eau sous la forme d'un composite discontinu constitué d'hydrogel et de poudre, ainsi que son procédé de production. L'algine et le sulfate de calcium, conjointement avec l'eau, forment un hydrogel discontinu et agissent comme liant pour les particules de poudre, l'amidon de maïs est gélatinisé en un amidon adhésif par de l'eau et agit comme un adhésif pour les particules de poudre, et l'hydrogel discontinu et l'amidon adhésif, conjointement avec les particules de poudre, peuvent former un composite discontinu d'hydrogel et de poudre possédant une structure tridimensionnelle. Le nettoyant solide à désintégrati
