example 1

Preparation of Deodorant Composition

[0129] A deodorant composition was obtained by adding 1 mol of each polyphenol described in Table 1 to the inside of a stirring vessel containing 50 mL of a 0.05M Na2CO3 solution (pH 11.2) and stirring the whole at 25° C. under conditions that air could freely flow and the surface of the reaction liquid could thoroughly come into contact with the air or allowing it to stand after the stirring under the same conditions. The stirring time and standing time are shown in Table 1.

example 2

Deodorizing Effect on Methyl Mercaptan

[0130] Into a 50 mL vial were placed 2 mL of the deodorant composition of Example 1 and 4 μL of a 15% aqueous solution of methyl mercaptan (Tokyo Kasei Kogyo Co., Ltd.) and the vial was capped with Parafilm, followed by stirring at 25° C. After 10 minutes, 50 mL of the head space gas in the vial was passed through a gas detecting tube (manufactured by Gastech Corporation) to measure the concentration of sulfur compounds, which remained in the gas and were malodor components, and a deodorization rate was calculated according to the following expression. The results are shown in Table 1.

Deodorization rate (%)=100×{1−(A / B)}

[0131] In the above expression, A means the measured concentration of the malodor components and B means the concentration of the malodor components measured in the control.

[0132] The control was prepared by adding a 0.05M Na2CO3 solution (pH 11.2) instead of the addition of 2 mL of the deodorant composition of Example 1.

Preparation of Deodorant Composition

[0137] One mmol of chlorogenic acid was added to the inside of a stirring vessel containing 50 mL of a 0.05M Na2CO3 solution (pH 11.2) and the whole was stirred at 25° C. for 3 hours under conditions that air could freely flow and the surface of the reaction liquid could thoroughly come into contact with the air. Then, the reaction liquid was freeze-dried to obtain 460 mg of an ocher powdered deodorant composition.

Abstract

It is intended to provide a novel deodorant composition which is excellent in the deodorizing effect, is capable of affording a deodorant composition by a convenient method, and shows no decrease in the deodorizing performance even after a long period of time, once the deodorant being prepared. Specifically, there is provided a deodorant composition containing, as the active component, a colored compound obtainable by reacting a polyphenol in a solvent showing alkalinity in the coexistence of an oxygen molecule at a reaction pH value of 6.5 or more. As a substitute for a polyphenol, use can be made of a plant extract containing a polyphenol but containing substantially no amino acid. It is also possible to further employ an amino acid. Furthermore, use can be made of a plant extract and / or a plant body containing a polyphenol and an amino acid.

Description

TECHNICAL FIELD [0001] The present invention relates to a novel deodorant composition. Specifically, it relates to a novel deodorant composition comprising a colored compound obtainable by reacting a polyphenol in a solvent showing alkalinity in the coexistence of oxygen molecules at a reaction pH value of 6.5 or more. Precisely, it relates to a novel deodorant composition comprising a colored compound obtainable by reacting a specific polyphenol in a solvent showing alkalinity in the coexistence of oxygen molecules at a reaction pH value of 6.5 or more and to a novel deodorant composition comprising a colored compound obtainable by reacting a specific polyphenol and an amino acid in a solvent showing alkalinity in the coexistence of oxygen molecules at a reaction pH value of 6.5 or more. More precisely, it relates to a novel deodorant composition to be used for elimination or reduction of odors felt in daily life, such as bad breath (halitosis), body odor, odor in refrigerator, odo...
