Problems solved by technology

Further, the person oneself or people around often feels the axillary odor itself uncomfortable rather than the body odor.
The method (1) needs professional panel members such as a skilled dermatologist, thus, it cannot be easily performed.
Also, the method (1) assesses the level of apocrine odor by smelling an odor of the cotton wool which wiped underarms of a test subject, which allows to mingle a judgment with a large degree of the assessor's subjectivity and has difficulty in a quantitative evaluation.
Further, when the evaluation is performed consecutively, a sense of smell may get tired so as to lower objectivity.
Therefore, there is a risk of false assessment with limited evaluation points and there is a possibility of ignoring axillary odor which is not actualized.
Also, such studies can be rough indications for assessing tragomaschalia habit, how

[0222] The following examples further describe and demonstrate embodiments of the present invention. The examples are given solely for the purpose of illustration and are not to be construed as limitations of the present invention.

example a

1. Screening of Test Subjects

[0223] Each of 65 healthy Japanese males selected at random as test subjects wore a new white T-shirt made of cotton for 24 hours consecutively and the T-shirts were collected. An organoleptic test by 7 professional panel members was conducted on the axillary regions of the collected T-shirts concerning kinds and strength of axillary odor.

[0224] Acid odor: sour and putrefactive odor

[0225] Cumin-like apocrine odor: spicy, woody and animal-like odor

[0226] Sulfur-like apocrine odor: fishy and soy sauce and grapefruit-like odor

[0227] 0: Odorless

[0228] 1: Slight odor

[0229] 2: Weak odor

[0230] 3: Easily perceptible odor

[0231] 4: Strong odor

[0232] 5: Very strong odor

[0233] As a result, 28 people were recognized to have little axillary odor (the strength of odor of these people was 1 or less) (herein after referred as Group A), 21 people were recognized to have weak axillary odor (the highest strength of odor of these people was 2 or 3) (herein after ...

1. Preparation of an Indicator Material for Assessing Body Odor

[0258] Mixtures of 3-hydroxy-3-methylhexanoic acid (Substance (A)) and 3-mercapto-3-methylhexanol (Substance (C)) was prepared at a 0.015% diluted concentration in ethanol, wherein Substance (A) :Substance (C)=50:1, 100:1 and 200:1, as indicator materials for assessing body odor for Example B-1, B-2 and B-3 respectively. Also, a 0.015% diluted solution of 3-methyl-2-hexenoic acid in ethanol was prepared as an indicator material for assessing body odor for Comparative Example B-2.

2. Evaluation of a Deodorizing and Masking Effect of an Indicator Material for Assessing Body Odor Against an Apocrine Odor

[0259] The test subjects were 6 people in the Group A (who were recognized to have no axillary odor) of Example A. Each of the above-mentioned indicator materials for assessing body odor (Examples B-1 to B-3 in Table 2) was sprayed to an axillary region of each test subjects once (about 30 mg) to apply the indicator mate...

Abstract

An indicator material for assessing body odor of the present invention comprises at least one member selected from the group consisting of a substance (A) which is a β-hydroxycarboxylic acid compound represented by the formula (1), a substance (B) which is a derivative of the compound represented by the formula (1), a substance (C) which is an alcohol compound having a mercapto group at the 3-position represented by the formula (2),and a substance (D) which is a derivative of the compound represented by the formula (2). The present invention also provides a method of producing the compound represented by the formula (2) by incubating perspiration originated from a human in an environment with an oxygen concentration of 10 v/v % or less. The present invention also provides a kit for assessing body odor of a human, wherein the kit for assessing body odor of a human includes a coloration reagent which reacts with β-hydroxycarboxylic acid originated from perspiration of a human.

Description

TECHNICAL FIELD [0001] The present invention relates to an indicator material for assessing a body odor, and a method for assessing a level of a body odor or effectiveness of a deodorant. [0002] Also, the present invention relates to an assessing kit and an assessment method including a coloration reagent, which reacts β-hydroxycarboxylic acid or the like originated from perspiration of a human with the coloration reagent. BACKGROUND ART [0003] Recently, number of people who are anxious about their body odor is increasing according to the growing desire for hygiene. The body odor is a collective term for an odor generated from any parts of a body, mainly a head, a mouth, underarms, a genital area, feet or the like. Particularly, since an axillary odor (odor of underarms) is easily sensed by a person oneself or people around, a level thereof, for instance, some factors including the presence, strength, difference in quality or the like of the axillary odor tends to dominate the level...
