  In the early stage of sweating, sweat hardly generates odor, but if left under moderate temperature / humidity, a bad odor known as so-called sweat odor is generated. Such sweat odor is generally deodorized with a deodorant containing a fragrance such as a cologne or perfume or a fragrance that masks the sweat odor. However, such a masking method using a fragrance does not eliminate the sweat odor, and there is a strong demand for a technique for suppressing the generation of the sweat odor itself.

  Regarding the deodorizers described in the above Patent Documents 1 to 3, the perfume ingredients specifically used in the examples are relatively highly volatile top notes and middles for instantly masking malodors. There are many that fall within the category of notes, and there are also examples using macrocyclic musk fragrances such as ethyl brushate, but there is nothing about the fact that specific macrocyclic fragrance ingredients can suppress the occurrence of sweat odor itself. There is no suggestion.

  Accordingly, an object of the present invention is to provide a sweat odor generation inhibitor composition and a sweat odor generation suppression method capable of suppressing the generation of sweat odor itself.

  The present inventors have examined in detail the mechanism of sweat odor generation, and phenolic compounds and indoles contribute to sweat odor rather than ammonia and fatty acids, which are generally considered causes of sweat odor. It has been found that these phenolic compounds and indoles are high components and are generated by the action of β-glucuronidase derived from bacterial cells on sweat.

  And until now, it has been found that some of the perfume ingredients that have not been used in the deodorization technology by the masking method because of its high retention and low volatility inhibit the activity of β-glucuronidase, and the present invention. Has been reached.

That is, this invention provides the sweat odor generation inhibitor composition containing the following (a) component and (b) component.
Component (a): 3-methyl-4-cyclopentadecene-1-one, 3-methyl-5-cyclopentadecene-1-one, 5-cyclohexadecene-1-one, 8-cyclohexadecene-1-one , One or more β-glucuronidase inhibitors selected from 9-cycloheptadecen-1-one, 7-cyclohexadecenolide and 10-oxa-16-hexadecanolide,
Component (b): One or more selected from surfactant (b1) and solvent (b2) The present invention also relates to a sweat odor generation inhibitor composition containing the component (a), the component (b), and water. A sweat odor generation inhibitor article comprising a container filled with a trigger sprayer, and a sweat odor generation inhibitor composition containing the above components (a), (b) and water, The present invention provides a method for suppressing the generation of sweat odor by bringing it into contact with a textile product or leather product to which water adheres.

  With the sweat odor generation inhibitor composition and sweat odor generation inhibitor article of the present invention, the generation of sweat odor itself can be suppressed.

It is at least one of 15 to 17-membered macrocyclic compounds selected from -1-one, 9-cycloheptadecen-1-one, 7-cyclohexadecenolide and 10-oxa-16-hexadecanolide. These compounds have a function of inhibiting the activity of β-glucuronidase and have an effect of continuously suppressing the generation of phenolic compounds and indoles.

<Method of measuring relative activity inhibition rate of β-glucuronidase>

From the obtained measured value, the relative activity inhibition rate of β-glucuronidase was determined according to the following formula.
