As a deodorizing method for odors and off-flavors represented by ammonia, amine, mercaptan, and sulfide, silica gel, activated carbon, etc. can be used to adsorb odors, or inclusion compounds such as cyclodextrin can be included in odorants, fragrances, etc. How to mask offensive odors and offensive odors with
A method of deodorizing a bad odor or a bad odor by a chemical reaction is known. This method is widely used mainly as a deodorizing device, but it cannot be applied to the human body or animal body, and the adsorption power of silica gel or activated carbon is low. The method described in (1) masks offensive odors and off-flavors with the odor of the deodorant itself, but it is difficult to control the amount of fragrance required for masking, and there are a wide variety of human tastes for fragrance. It is uncommon for some people to feel disgust. The method of (1) requires careful handling of the drug used, and is difficult to apply to the human body or animal body. Therefore, these methods can be used to remove the offensive odors and offensive odors generated in homes and factories according to their respective purposes. As a method,
These methods are not suitable.

On the other hand, with the recent increase in cleanliness,
Development of deodorants for removing halitosis, fecal odors and body odors of humans and animals is desired. Copper chlorophyllin Na is known as an active ingredient for removing bad breath and is often used in various oral compositions. However, when copper chlorophyllin Na is added to an oral composition such as toothpaste in an amount capable of exerting an effective deodorizing effect on mercaptan and the like, the color of the oral composition becomes very dark. Further, as deodorant active ingredients, red beet extract, cacao extract, coffee parsley extract (JP-A-60-2076).

EXAMPLES The present invention will be further described below with reference to examples, but the present invention is not limited to these examples.

<Preparation of Specimen> Guava leaves, sycamore leaves, lotus roots, and puerh tea are cut into pieces,
Extracts obtained by crushing and slicing each of the following plants: 200 g of 50% ethanol was added, and the mixture was heated under reflux for 1 hour and filtered through Celite. The liquid was concentrated under reduced pressure to remove ethanol, purified water was added to make the total amount 200 ml, and the sample was filtered with filter paper to obtain a sample. After adjusting the pH to 7.2 by adding 1N sodium hydroxide solution to 75 ml of this sample (corresponding to 3 g of plant), a phosphate buffer (pH 7.2) was added to bring the total volume to 100 ml. As a control, copper chlorophyllin Na (manufactured by Tama Seikagaku)
To a solution of 1 g dissolved in 75 ml of purified water, p with 10% phosphoric acid.
After adjusting to H7.2, phosphate buffer (pH 7.2) was added to make the total volume 100 ml. As a blank, phosphate buffer (pH 7.2) was added to 75 ml of purified water to bring the total volume to 10 ml.
What was made 0 ml was used.

<Deodorization test> A methyl mercaptan standard solution (1 μg / μl benzene solution: manufactured by Wako Pure Chemical Industries, Ltd.) was poured into a 3500 ml glass reagent bottle so as to have a concentration of 6 to 7 ppm, and the bottle was tightly sealed and kept at room temperature for 10 minutes. After standing at (25 ° C.), the concentration of methyl mercaptan gas (0 minutes) in the container was measured using a gas detector tube (all mercaptan 70L: manufactured by Gastec). To this, 100 ml of the sample solution was quickly added, shaken and mixed, and the concentration of methyl mercaptan gas in the container after standing for 5 minutes and 60 minutes was measured. The sampling amount to the gas detector tube was 50 ml (1.4%) above 4 ppm and 100 ml (2.8%) below 4 ppm, and the same amount of air was introduced into the container after sampling. Table 1 shows the results.
