JP2857736B2 - Deodorant containing rooibos tea aqueous extract - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a deodorant consisting of an aqueous extract of rooibos tea.

[0002]

2. Description of the Related Art Various deodorants have been conventionally known as daily necessities, but they are not always in a satisfactory state.

On the other hand, Aspalat, a plant from South Africa
There is a kind of health drink obtained by drying and fermenting the leaves of hus Linearis, Rooibo
Also known in Japan as s tea). The present invention
It was completed based on the discovery that an aqueous extract of rooibos had a strong deodorant effect.

[0004]

[Means for Solving the Problems]

That is, the present invention provides rooibos with water,
Particularly preferred is a deodorant containing an extract obtained by extraction with hot water. For extraction, hot water alone or ethanol, glycerol, 1,3
-A hydrophilic organic solvent such as butylene glycol may be added. By concentrating under reduced pressure after the extraction, a fluid or viscous liquid containing the extract having a desired concentration can be obtained. This may be used as it is as a deodorant, or it may be further concentrated and solidified to be used as a powder. The concentrated liquid containing the extract or the solidified extract may be mixed with a suitable excipient to form a powder or granules. Suitable excipients include, for example, zeolite, lactose,
Starch, dextrin, crystalline cellulose and the like can be mentioned, but other excipients can be appropriately selected.

It is also possible to use an extract obtained by mixing the extract with a gel substance, adsorbing it on a porous material, for example, a porous sintered material, or impregnating paper or other fiber material.

[0007] The deodorant of the present invention is excellent either by bringing it into contact with a gas containing an odor in the gas phase or by adding it to a liquid (such as water) containing a compound serving as an odor source. Demonstrate the deodorant effect. Thus, for example, liquid drinking water, for the deodorization of seasoning foods, and as quasi-drugs for deodorization in the mouth, deodorization such as axillary odor, and further in the form of spray,
In the form of being mixed with a gel substance and adsorbed on a porous material or impregnated in paper or other fibrous material and supported, indoor deodorization,
It can be used for deodorizing refrigerators, deodorizing shoes, and other various deodorizing applications. The following experimental examples demonstrate the effect of the deodorant of the present invention.

Experimental Example 1 Deodorizing action in gas phase. The following four types of standard malodorous gases were collected in a 500 mL sealed Erlenmeyer flask, and at the same time, the aqueous extract of rooibosty, which is an active ingredient of the deodorant of the present invention, was concentrated in each flask. 1 g of an aqueous solution having a solid content of 5% was added, and after 10 minutes and 30 minutes, the residual concentration of the malodorous gas in the container was measured with a detector tube, and the removal rate was calculated. As a result, as shown in Table 1 below, the deodorant of the present invention based on the aqueous extract of rooibos tea effectively removed standard malodorous gases such as ammonia, acetaldehyde, trimethylamine and hydrogen sulfide.

Experimental Example 2 Deodorizing action in liquid phase. To a solution prepared by dissolving 0.1 g of garlic extract in 100 mL of water was added 1 mL or 2 mL of a 5% solids aqueous solution obtained by concentrating the aqueous extract of rooibosty, which is an active ingredient of the deodorant of the present invention. The presence or absence of odor was determined by six subjects in the following six stages. Odorless = 0 Smell detectable = 1 at last. Weak smell = 2 to know what smell it is. Smell to be able to know easily = 3. Strong smell = 4. Strong smell = 5. As a result, as shown in the following Table 2, the addition of the deodorant of the present invention based on the aqueous extract to rooibos effectively deodorized the odor of the aqueous garlic extract solution.

[Example 1] Solution Embossy (5 mm cut tea leaf) 7.0 g in 1000 mL
And boiled for 10 minutes. After keeping it warm and leaving it for 20 hours, it was boiled again for 10 minutes. The tea leaves were removed, and the extract was concentrated under reduced pressure to obtain a deodorant. The solid content was about 0.8 g.
