<p>Conventional tannic acid and polyphenol anti-allergen agents are known as anti-allergen agents capable of deactivating allergens such as mites and pollen, but these agents have inferior heat resistance and pose problems with coloration, discoloration and elution. The purpose of the present invention is to provide an anti-allergen agent that has excellent heat resistance, shows no coloration, and has excellent water resistance and workability. It was discovered that using an inorganic substance having a high acid site concentration with acid site concentration being defined as the number of acid sites having a pKa of 4.8 or less, it is possible to realize an anti-allergen that manifests strong anti-allergen effects, has excellent heat resistance and water resistance, shows little coloration, and has excellent workability.</p> |
