JPS63174920A - Deodorant - Google Patents

Abstract

PURPOSE:To obtain a deodorant quickly impregnating into skin, free from irritation and side effects and exhibiting deodorizing effect against various kinds of offensive odor, by using a deodorizing active substance selected from the group of SHAKUYAKU (dried root of Paeonia albiflora), BOTANPI (dried root skin of Paeonia moutan) and their extract. CONSTITUTION:The objective deodorant contains one or more kinds of substances selected from SHAKUYAKU, BOTANPI and the their extract as a deodorizing active substance. The extract is produced by the extraction of the root of Paeonia albiflora or root skin of Paeonia moutan with water or aqueous alcohol usually at 15-25 deg.C. The amount of the active substance is >=0.005wt.% and preferably up to about 10wt.%.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a deodorant containing one or more deodorizing active substances selected from the group consisting of crude drugs such as peony, botanpi, and extracts thereof.

[Prior Art] Many explanations for the causes of biologically-derived bad odors such as armpit odor, sweat odor, foot odor, hair products, and menstrual odor are that they are caused by bacterial decomposition of sweat [for example, Labows and Kligman]. 'J, Soc, Cosme
t, Chem, 34 (1982) J, p. 193]. A large number of products are available to prevent or treat these odors, and many of these products contain antiperspirants, disinfectants, masking agents, adsorbents, and the like. Most antiperspirants that reduce sweat production are astringent aluminum compounds, usually aluminum chloride. On the other hand, hexachlorophene and various quaternary ammonia compounds are often used as disinfectants to inhibit the growth of bacteria that cause bad odors. Further, as a masking agent, a substance having a pleasant odor such as eugenol is used.

Currently, these antiperspirants, disinfectants, and masking agents are blended into products alone or in any combination.

[Problems to be solved by the invention] By the way, antiperspirants have the effect of reducing sweat, which is the source of sweat odor components, but it is impossible to completely suppress sweating from a physiological perspective. Moreover, considering its mechanism of action, it has the disadvantage that it cannot control sweat odor that has already occurred.

On the other hand, disinfectants that decompose sweat and inhibit the growth of bacteria that cause bad odors have been pointed out to have safety issues, and have the disadvantage that they cannot be formulated in sufficient concentrations to be effective.

Furthermore, masking agents have the disadvantage that they may mix with sweat odor and generate unpleasant odors.

Therefore, the above-mentioned conventional deodorizers or deodorizers containing antiperspirants, disinfectants, and masking agents are not effective, safe, or effective.
Furthermore, there was a problem that the usability was not fully satisfactory.

Therefore, the present inventors conducted research to solve the problems of the prior art and found that one or more selected from the group consisting of peonies, botanpis and their extracts are used as deodorizing active substances. The inventors have discovered that the above-mentioned problems can be solved by the following methods, and have arrived at the present invention.

[Means for Solving the Problems] That is, the present invention provides a deodorant containing one or more kinds selected from the group consisting of peonies, botanpis, and extracts thereof as deodorizing active substances. Examples include external deodorants such as aerosols, roll-ons, powders, creams, and sticks, milky lotions, lotions, lotions, and even household deodorants.

The present invention will be explained in detail below.

The peony used as a component of the deodorizing active substance in the present invention is a member of the Paeonaceae family (Paeon 1aceae).
) Peony root, and botanpi is the dried root bark of peony, also a member of the peony family. The extract of Peony or Botanpi is obtained by extracting the root of the peony or the root end of Botanpi using water or an aqueous alcohol such as ethanol, usually at 15 to 25°C.

The amount of the extract (residue after distilling off the extraction solvent) is approximately 0.005% in the total composition. The upper limit of the blending amount is not particularly limited, but from the viewpoint of commercial value such as coloring, it is preferable that the blending amount of peony, botanpi and their extracts is about 10% by weight in total as the dry residue.

As other components of the deodorant, any conventionally known components can be blended. For example, aluminum hydroxychloride, aluminum chloride, aluminum sulfate, basic aluminum bromide, aluminum phenolsulfonic acid,
Antiperspirants such as tannic acid, aluminum naphthalene sulfonic acid, basic aluminum iodide, 3.4.4-trichlorocarbanilide (TCC), benzalkonium chloride, benzethonium chloride, alkyltrimethylammonium chloride, resorcin, phenol, sorbin Acid, salicylic acid, disinfectants such as hexachlorophene, Jacora,
In addition to masking agents such as skatole, lemon oil, lavender oil, absolute, jasmine, vanillin, benzoin, benzyl acetate, and menthol, oils, surfactants, water, alcohols, etc. may vary depending on the dosage form. Sugars, esters, preservatives, vitamins such as vitamin A1 vitamin D1 vitamin E1, hormones such as estradiol and cortisone, anti-inflammatory agents such as allantoin, humectants, thickeners, fragrances,
Dyes and the like may be appropriately added within a range that does not impair the effects of the present invention.

[Effect of the invention] A deodorant characterized by containing one or more kinds selected from the group consisting of peony, botanpi and their extracts as a deodorizing active substance penetrates particularly well into the skin and does not cause irritation or irritation. It has no side effects and exhibits deodorizing effects against various bad odors. It is also effective against bad odors that occur at home.

[Examples] Next, the present invention will be described in detail with reference to Examples, but the scope of the present invention is not limited to these Examples. The test method is as follows.

(Deodorization test method) A deodorant containing peony according to the present invention was tested using a panel of 10 healthy men who were aware of having underarm odor. The test product was applied directly to the test subject's armpit only four times, once in the morning and once in the afternoon, for two days. The area under the armpit where it is not applied is used as a control.

Judgment is based on the following five-stage criteria, namely: 0: No armpit equipment i = Slight smell of armpits 2: There is a distinct smell from the armpits. 3: Armpit equipment smells 4: Very strong armpits According to.
