Diketone activity inhibitor

Abstract

The present invention provides a diketone activity inhibitor with which it is possible to effectively inhibit the activity of a diketone compound, and provides a body odor suppressant with which it is possible to effectively suppress body odor, especially acid smells in the axillary region and oily smells in the head region. The present invention is: a diketone activity inhibitor that inhibits the activity of a diketone compound represented by general formula (I): R1-(CO)-(CO)-R2 (I) (In the formula, R1 and R2 each independently represent C1-4 alkyl groups), said diketone activity inhibitor containing at least one type of extract selected from the group consisting of meadowsweet extract, Himalayan raspberry extract, Tilia miqueliana extract, and rose extract; and a body odor suppressant that contains said diketone activity inhibitor.

Description

technical field [0001] The present invention relates to a diketone action inhibitor. More specifically, the present invention relates to a diketone action inhibitor and a body odor inhibitor useful in cosmetics, quasi-drugs, pharmaceuticals, miscellaneous goods, and the like for people who are concerned about body odor. Background technique [0002] In recent years, with the continuous improvement of cleanliness intentions, there is an increasing trend of people who are concerned about their own or other people's body odor. Body odor is a mixture of various odors from various parts such as armpits, head, trunk, toes, and soles of feet. Among these parts, for example, the armpits and the head are the parts with a large amount of sweat secretion, and the sweat is not easy to evaporate, and it becomes an environment where the skin resident microorganisms are easy to multiply. In the armpits and the head, components contained in sweat are decomposed by skin resident microorgan...

AI Technical Summary

Problems solved by technology

[0005] However, in the above-mentioned deodorants, body odor, especially sour odor of the armpits and oily odor of the head cannot be sufficiently suppressed in some cases, and therefore a body odor suppressant capable of effectively suppressing such body odors is required.

In addition, the present inventors have not found any literature that specifically describes the correlation between the production of diketone compounds on the skin and body odor, or the means for suppressing body odor by utilizing this correlation.
