An object of the present invention is to provide a composition for reducing allergens with less coloring when performing surface processing on a building interior decoration material, a non-woven fabric, and a fibers or fiber product a spray agent capable of reducing various allergens in the environment and a building interior decoration material, such as a non-woven fabric, a fiber or fiber product, a wall paper, a floor material, and a ceiling material, allergen reducing performance. The solution of this invention is using an allergen reducing composition containing zinc salts and rare earth salts to reduce allergens such as mites and cedar pollen and imparts a function of reducing allergens to fiber or fiber product, such as carpet, tatami mat, bedding, window curtain, clothing, stuffed toy, mask, filter material, and dust collection bag of electric vacuum cleaner and building interior decoration material, such as wall paper, floor material, and ceiling material.本發明之課題的目的為提供可於建築用內裝材、不織布、纖維或纖維製品進行表面加工之著色少的降低過敏原之組成物;用以降低存在於環境中之各種的過敏原之噴霧劑;具有降低過敏原之性能的不織布、纖維或纖維製品、壁紙、地板材料、天花板材料等之建築用內裝材。本發明之解決手段係可藉由使用含有鋅鹽及稀土類鹽的降低過敏原之組成物,而使蟎或柳杉花粉等之過敏原降低,還可對地毯、榻榻米、寢具類、窗簾、衣服、布偶、口罩、過濾器材料、電動吸塵器的集塵袋等之纖維或纖維製品、壁紙、地板材料、天花板材料等之建築用內裝材賦予使過敏原降低之機能。
