PURPOSE:To provide the titled composition containing copper gluconate and a polar solvent extract of plant of Camellia family, capable of completely eliminating foul breath composed of amine smell and sulfur compound smell by the use of an extremely small amount of the composition nd usable without causing color staining. CONSTITUTION:The objective composition contains (A) an extract produced by extracting leaf of a plant of Camellia family with a polar solvent, preferably with a 20-80% aqueous solution of glycerol at 50-100 deg.C and (B) copper gluconate. The amounts of the components A and B having deodorizing titer of (n) are nX(4.5-5.5)pts.wt. and 1pt.wt., respectively. The deodorizing titer is defined by the volume (m1) of 500ppm aqueous solution of the extract necessary to essentially eliminate the smell of 1ml of 1,000ppm aqueous solution of trimethylamine. The composition is added to mouth wash, chewing gum, candy, dentifrice, etc., at ratios of 0.0005-0.5wt% component A (in terms of 1.0 deodorizing titer) and 0.0001-0.1wt% component B.
