To improve a use effect and safety without degrading the taste and use feel of an object to be added with this deodorant by using the tannin extracted from Caesalpiniaceous spinosa as an effective component.
This deodorant is formed by using the tannin extracted from the legumes of the spinosa of the Leguminoous perennial plants grown in the dry zones in the Western parts of the South American continent as the effective component. The extracted tannin is the hydrolysis decomposition type gallotannin basically consisting of a structure in which plural pieces of gallic acids are ester bonded to a quinic acid which is cyclic polyhydric alcohol. This tannin is extracted by water, hydrophilic org. solvent or their mixture by pulverizing the trunks, branches, legumes and pericarps of the spinosa as they are or after drying the same. Methanol, ethanol, etc., are usable as the hydrophilic org. solvent. As a result, the deodorization of the object to be added with the deodorant is made possible without impairing the taste and use feel thereof.
