PURPOSE: A powdery deodorizing agent is provided to increase the foul odor removal range and to be easily handled. CONSTITUTION: A powdery deodorizing agent is formed in the form of power which is prepared by mixing 40-70 wt% of activated carbon as an inorganic material and 20-50 wt% of biotite and grinding the mixture. The inorganic material comprises 40-84 wt% of silicic acid, 10-30 wt% of alumina, 1-5 wt% of iron oxide, 1-5 wt% of calcium oxide, 1-5 wt% of magnesium oxide, 1-5 wt% of sodium oxide, 1-5 wt% of potassium oxide, and 1-5 wt% of IgLoss. The activated carbon and biotite are ground in 280-330 mesh.본 발명의 분말형 탈취제는 규산질광물 또는 규산알루미늄광물 중 어느 하나의 무기질재료로 이루어지는 첨착활성탄 40~70중량% 및 흑운모 20~50중량%를 혼합하여 분쇄시킨 분말의 형태로 이루어진다.
