Description

  The present invention relates to a deodorant containing a plant or plant-derived extract as an active ingredient, which suppresses the production of volatile steroids, and a cosmetic, pharmaceutical, or quasi-drug containing the plant or plant-derived extract. The present invention relates to a deodorant preparation selected from products, fiber deodorants, and a fiber deodorant treatment method using the plant or plant-derived extract. More specifically, it contains a deodorant containing a plant or plant-derived extract, which has a volatile steroid production inhibitory effect without sterilizing resident bacteria, and contains the plant or plant-derived extract. The present invention relates to a deodorant preparation selected from cosmetics, pharmaceuticals, quasi drugs, and fiber deodorants, and a fiber deodorant treatment method using the plant or plant-derived extract.

  Conventionally, as a method for preventing body odor such as sweat odor, a deodorizing technique and a masking technique are mainly used. In recent years, a method for suppressing the generation of body odor has been put into practical use by a sterilization technique for sterilizing causative bacteria that produce a substance causing body odor. However, the deodorizing technique and the masking technique are not satisfactory in terms of the degree of effect and sustainability. Moreover, since the said sterilization technique also sterilizes skin resident bacteria other than odor-producing bacteria, there was a concern of lowering the skin barrier function (for example, see Non-Patent Document 1 below).

  Therefore, recently, a technique for suppressing the generation of body odor without sterilizing the skin resident bacteria has been proposed (see Patent Document 1 below). That is, in the metabolism of skin resident bacteria, for example, a causative substance of body odor such as androste-16-enes, which are volatile steroids, is generated. Therefore, the technique inhibits metabolic enzymes of skin resident bacteria. This suppresses the generation of the body odor causing substance and suppresses the generation of body odor.

  In Patent Document 1, β-glucuronidase inhibitors that suppress the production of androste-16-enes, which are said to be the cause odor of human body odor, mainly glandular odor, include, for example, ougon, gobishi, gardenia, shikon, peony In addition, plant extracts such as enamel, chamomile, and acupuncture are studied, and it is disclosed that the generation of unpleasant body odor can be suppressed without sterilizing the skin resident bacteria.

  On the other hand, with respect to volatile steroids, it is known that nonvolatile steroid sulfate secreted on the skin is metabolized and produced by skin resident bacteria (see Non-Patent Document 2 below).

  Examples of 4-ene reductase and 5α-reductase inhibitors that suppress the production of volatile steroids by the skin resident bacteria include (Z) -3,4,5,6,6-pentamethylhept-3-ene Perfume ingredients such as 2-one, diethyl-cyclohex-2-en-1-one and dimethyl-cyclohex-2-en-1-one, citronellol, etc. have been studied, and skin resident bacteria (odor-producing bacteria) ) Can be suppressed without sterilization (see Patent Document 2 below).

JP 2002-255776 A JP-T-2002-519369 Katsuyuki Takeda, “The New Knowledge of Skin Defense Function: Role of Acnes and Epidermidis as Permanent Bacteria”, Journal of the Japan Cosmetic Science Society, 2003, Vol. 27, No. 1, p. 29-32 Gower D. B. , J .; Steroid Biochem. Molec. Biol. , Vol. 63, no. 1-3, p. 81-89, 1997

  However, the β-glucuronidase inhibitor disclosed in Patent Document 1 cannot suppress the production of volatile steroids from non-volatile steroid sulfate, and suppresses the production of androste-16-enes. Is insufficient. Therefore, the β-glucuronidase inhibitor does not provide a satisfactory body odor suppressing effect.

  In addition, in the inhibitor of 4-ene reductase and 5α-reductase disclosed in the above-mentioned Patent Document 2, which is involved in the volatile steroid production pathway of skin resident bacteria, the production suppression of volatile steroids is suppressed. Since it is insufficient, the effect which can be satisfied in the point of suppression of body odor is not acquired. This is thought to be due to the fact that multiple pathways are involved in the generation of volatile steroids, and that 4-ene reductase and 5α-reductase inhibitors only block some of the pathways. .

  This invention is made | formed in view of the said situation, Comprising: The objective of this invention is the plant or plant-derived material which can suppress continuously the production | generation of the volatile steroid which is one of the causative substances of body odor.

Another object of the present invention is to provide a method for treating fiber deodorant.

  In order to solve the above-mentioned problems, the present inventors have made extensive studies on the volatile steroid production-inhibiting action of extracts from various plants and the like. As a result, β-glucuronidase, 4 -Regardless of whether or not the inhibitory action of enreductase and 5α-reductase is present, it has the effect of highly and continuously suppressing the production of volatile steroids, specifically androstenone, which is one of the main causative agents of body odor. The headline and the present invention were completed.

  That is, the deodorant preparation including the deodorant agent and the fiber deodorant of the present invention is characterized by containing, as an active ingredient, an extract of a plant or a plant-derived product having an effect of suppressing the generation of volatile steroids. The volatile steroid production suppression rate of the plant or plant-derived extract is 90% to 100% in a volatile steroid production system using Corynebacterium xerosis, which is one of the skin resident bacteria. Preferably there is. Moreover, it is preferable that the deodorant agent and deodorant preparation of the present invention do not exhibit bactericidal action against skin resident bacteria.

  The “deodorant agent” as used in the present invention refers to a drug used to prevent body odor such as odor and foot odor.
