Description

Body odor composition and fragrance composition for suppressing body odor

technical field

The present invention relates to a body odor composition which is closer to the special smell of real body odor, more specifically, relates to a body odor composition which is closer to the special smell of body odor, for example, due to the Sweat odor and armpit odor, preferably the composition can be used to evaluate the effects of masking, reconciling or removing sweat odor, armpit odor, etc.; method with equal effect.

Furthermore, the present invention relates to a fragrance composition for suppressing body odor, and more particularly, relates to a fragrance composition for suppressing body odor, which can effectively mask and/or moderate odors due to body odor and sweat. Acidic odor, and a deodorant composition or topical treatment composition containing the same, and a novel method for suppressing body odor.

Background technique

Odor has become very important especially recently for the reasons of feeling clean and pleasant; among them, the need to remove odor emanating from the human body, that is, the need to remove body odor is particularly strong. Odors known to emanate from the human body include scalp or hair odor, oral odor, sweat odor, underarm odor, foot odor, and the like. On the other hand, it is also highly desirable to remove mouth odor, feces and urine odor due to sulfur compounds, etc., and putrefaction odor due to specific components of decomposition products of organic compounds. Among these odors, underarm odor is considered to be an odor produced by the secretion of sweat glands, such as sebaceous glands, eccrine glands, eccrine glands, etc., through oxidation or the action of microorganisms. Odors such as sweat and feet, including underarm odor, create unpleasant sensations between people. Therefore, there have been various means to remove this odor so far. Based on this situation, it is highly desirable to provide the market with products for suppressing or reducing body odor including underarm odor and sweat odor.

For the method of removing odor, various methods are known, such as a method of suppressing odor generation by inhibiting the formation of substances capable of generating odor, a method of inhibiting the proliferation of microorganisms related to odor generation, and masking with special fragrances. method of odorous substances. In various products available on the market, at least one of these methods is used to remove the odor. To further illustrate, for example, in a commercially available product, an antiperspirant is combined according to its use, which inhibits profuse sweating which produces an odorous substance, a bacteriostatic or fungicide, and Inhibits the proliferation of microorganisms, a masking agent, has components that emit fragrance, etc. An astringent aluminum compound is the main ingredient in almost all antiperspirants, usually aluminum chloride. In addition, hexachlorophene and various quaternary ammonium chlorides are commonly used as bacteriostats or fungicides. Also, for the masking agent having a fragrance-releasing component, various fragrances can be used, for example, in Published Japanese Patent Application (JP-A) No. 6-179610, Japanese Patent Application National Publication (Published) No. .2002-505264, and Japan Patent Office: Published collection of well-known prior arts (perfume), partI, general of perfume (Jan.29, 1999) the spices recorded in pages 230-250.

When developing these various products having an odor masking or deodorizing effect, it is necessary to pre-evaluate the odor masking effect and deodorizing effect of substances or compositions used therein for screening. So far, when evaluating the masking effect and deodorizing effect of these odors, the evaluation has generally been performed using human bodies. However, there are some problems with the human body used for the evaluation. It is difficult to guarantee the reliability of the test taker who participates in the evaluation besides the excessive tension imposed on the test taker, and it is impossible to guarantee that the same The phenomenon. Furthermore, just as new compounds and compositions are being evaluated, there are safety concerns. At this time, if a pseudo-odor composition is used in the evaluation, new compounds and compositions can be evaluated without taking the above-mentioned problems into consideration.

Therefore, it is necessary to search for human body simulated odors for simple masking, blending and deodorizing evaluation of odors, such special odors include, for example, sweat odor, underarm odor, and the like. So far, components of various body odors such as mouth odor, scalp odor, underarm odor, foot odor, sweat odor, etc. have been studied (see, for example, Journal of Chemical Ecology , (USA) 1991, 17(7), pp. 1469- 1492 pp.; Head Office of 46 ^th TEAC Meeting (hosted by the Chemical Society of Japan), 46 ^th Discussion on perfume/Terpene and essential oil chemical, contents of lecture , 2002, pp. 124-126; and Published European Patent Application No. .1,258,531). If a body odor composition that is very close to the real body odor can be obtained, obviously, as mentioned above, on the one hand, research to ensure the safety of new substances or compositions used in the human body, on the other hand, in parallel, do not consider safety For underarm odor and sweat odor, research on how to accurately, simply and effectively evaluate the masking, blending or deodorizing effects of substances or compositions can effectively screen substances and compositions with such effects.

On the basis of the study of body odor components, further research is needed to prepare model odors and propose model odors. Among human simulated odors, for scalp odors, model odors for evaluation containing squalene, cholesterol, and fatty acids as main components have been disclosed (JP-A Nos. 2001-220593 and 2001-271088) . On the other hand, as for the smell of sweat, the component that is produced when lipid-secreting substances and higher fatty acids are oxidatively decomposed by bacteria inherent in the skin has been mainly studied. However, pseudo-odors closer to real sweat smells, in particular, special smells secreted from exocrine glands such as armpits have not been obtained. Exocrine glands are also present in the eyelids, external auditory canal, around the anus, around the nipples, etc. other than the armpits.

On the other hand, in deodorant products, various fragrance compositions can be mixed; however, those fragrance materials which can effectively mask armpit odor and fragrance materials which have sufficiently satisfactory characteristics have not been provided yet.

Contents of the invention

Based on the above situation, the present inventors analyzed the components obtained from human axillary parts through solvent extraction by gas chromatography, odor determination, mass spectrometry, etc., and found that the peaks at this time represent the odor characteristics of underarm odor. Furthermore, by means of mass spectrometry and chemical synthesis, the composition can be determined. So far, various carboxylic acids including 3-methyl-2-hexenoic acid and acetic acid have been reported as components of sweat odor. In addition, as a result of research by the present inventors, it was recently found that the ratio of enantiomers of 3-hydroxy-3-methylhexanoic acid and hydroxycarboxylic acid contained in the underarm odor component, that is, enantiomeric The ratio of the R-body to the S-body of the body is 1:3. The odor of the compound may indicate underarm odor different from those hitherto known odors of 3-methyl-2-hexenoic acid. As for the odor of hydroxycarboxylic acid, no method of masking it with an odorous component has been reported.

Therefore, the object of the present invention is to provide a kind of body odor composition, and this composition is closer to the real sweat smell, especially the special smell secreted from the exocrine glands, so that the masking and suppression of sweat smell and underarm odor can be correctly evaluated. effects, etc.; and a method for evaluating the masking, harmonizing or deodorizing effect on sweat odor, such as underarm odor, using the composition.

Therefore, with this composition, it is possible to accurately and effectively evaluate the masking ability, toning effect, or deodorizing effect against sweat odor, underarm odor, and the like. As a result, substances having a masking ability, a conditioning effect, or a deodorizing effect on odors such as sweat odor and underarm odor can be effectively screened. Therefore, the body odor composition and evaluation method according to the present invention can be applied to the development of odor masking agents, deodorants and odor suppressants, and various body deodorants, various body deodorants mixed with masking agents, deodorants or odor suppressants.
