Process for production of highly pure quaternary ammonium salt

High odor eliminating property is provided to a building material for interiors by compounding a hydrazide compound. Additionally, the odor eliminating property of the building material for interiors is improved and hygroscopicity and size stability at the time of use are provided by adding and compounding an organic carbide, an inorganic hygroscopic material, and a water repellent. Also, an interior structure in which these building materials for interiors are employed is provided.

Interior construction material having deodorizing activity
