Allergen-reducing composition, spray agent and surface treating agent containing said composition, allergen-reducing method, and fiber structure and building core material from which allergens are reduced
Provided is an allergen-reducing composition which can reduce allergens such as dust mites and cedar pollen, and which hardly colors an object from which allergens are to be reduced. Also provided are: a spray agent and surface treating agent using said composition； an allergen-reducing method； and a fiber structure and building core material from which allergens are reduced. The allergen-reducing composition contains one or more compounds (A) selected from a group consisting of zinc salt and copper salt, and one or more compounds (B) selected from rare earth salts. The spray agent and the surface treating agent contain one of the abovementioned allergen-reducing compositions, and water or a water-soluble solvent. The allergen-reducing method processes the allergen-reducing composition in an environment in which allergens are present. The fiber structure is a structure in which the allergen-reducing composition is processed, and the building core material is a material in which the allergen-reducing composition is processed.
