Definitions
- the present invention relates to a skin flora improving agent and a skin topical composition that use sophorose.
- Staphylococcus epidermidis also known as Staphylococcus epidermidis.
- This resident bacterium breaks down sebum to produce fatty acids that keep the skin slightly acidic, and glycerin, a moisturizing ingredient, and produces antibacterial peptides that inhibit the growth of pathogenic bacteria, thereby enhancing the skin's barrier function.
- Staphylococcus hominis also known as Staphylococcus epidermidis, is also known as a resident bacterium of the epidermis that promotes the expression of antibacterial peptides and other substances, thereby enhancing resistance to pathogenic bacteria.
- Cutibacterium acnes known as the acne bacterium

- Patent Document 5 discloses an invention of a skin flora balance improver that contains lactosucrose as an active ingredient.
- the object of the present invention is to provide a skin flora improving agent that is useful for maintaining good skin condition.
- sophorose as a material that selectively promotes the growth of bacteria that have a positive effect on the skin, which led to the completion of this invention.
- the present invention provides a skin flora improving agent that contains sophorose as an active ingredient.
- the skin flora improving agent is preferably intended to promote the growth of Staphylococcus epidermidis and/or Staphylococcus hominis while bacteriostatically inhibiting one or more species selected from the group consisting of Cutibacterium acnes, Staphylococcus aureus, Corynebacterium xerosis, and Micrococcus luteus.
- the present invention provides a composition for external use on the skin that contains the above-mentioned skin resident flora improving agent.
- sophorose by using sophorose, it is possible to suppress the growth of bacteria that are resident on the skin and that may have a negative effect on the skin, while promoting the growth of beneficial bacteria that have a positive effect on the skin.
- FIG. 13 is a graph showing the results of investigating the change in the number of bacteria when various kinds of bacteria that are normal skin flora were cultured under culture conditions suitable for each bacteria in Test Example 5, and the culture medium was added with highly purified laminaribiose or gentiobiose, or commercially available cellobiose.
- the skin flora improving agent of the present invention uses sophorose as its active ingredient.
- Sophorose (English name: Sophorose, also known as 2-O- ⁇ -D-glucopyranosyl-D-glucose) is a disaccharide in which two glucose molecules are linked by a ⁇ -1,2 bond. It was first discovered as a sugar component of the glycoside pigment in the pods of the sophora japonica, a legume plant, but it rarely exists in nature in the form of a free disaccharide, and it is a sugar that exists in very small amounts in nature. It is only known to exist in small amounts in acid hydrolysates of starch and in royal jelly.
- sophorose can be obtained by allowing microbial ⁇ -glucosidase to act on glucose and/or ⁇ -glucooligosaccharides and utilizing the condensation and sugar transfer reactions that ⁇ -glucosidase possesses. Also, as explained in detail in Japanese Patent No. 7025941, a method in which 1,2- ⁇ -oligoglucan phosphorylase acts on ⁇ -glucose-1-phosphate and glucose can be used to obtain sophorose in higher yields.
- a composition containing sophorose can be obtained.
- the obtained composition containing sophorose can be subjected to processes such as filtration, decolorization, deodorization, and desalting, as necessary.
- it may be subjected to processes such as extraction, centrifugation, crystallization, microbial assimilation, and further fractionation by chromatography using activated carbon, porous carriers, hydrophobic resins, hydrophilic resins, ion exchange resins, adsorption resins, etc., dialysis, membrane fractionation such as ultrafiltration, etc.
- the purity of sophorose can be increased by these processes.
- sophorose can be used in a highly purified form, but any substance that contains sophorose can also be used, i.e., a sophorose-containing sugar composition can also be used.
- the sophorose content in the sophorose-containing sugar composition used in the present invention is not particularly limited, but is preferably, for example, 10% by mass or more per dry solid content, more preferably 30% by mass or more, even more preferably 50% by mass or more, and most preferably 80% by mass or more. If the sophorose content per dry solid content is less than 5% by mass, the functionality of sophorose may not be fully exerted.
- the sophorose-containing saccharide composition used in the present invention may contain other components such as saccharides and oligosaccharides having different bond patterns and degrees of polymerization.
- Typical examples include those containing one or more of sophorooligosaccharides (excluding sophorose), which are oligosaccharides with degrees of polymerization of 2 to 10, such as gentiooligosaccharides, cellooligosaccharides, and laminarioligosaccharides, each in the amount calculated as a dry solid content shown below.
- Sophorooligosaccharides 5% by mass to 80% by mass Gentiooligosaccharides: 5% by mass to 50% by mass Cellooligosaccharides: 5% by mass to 50% by mass Laminarioligosaccharides: 5% by mass to 50% by mass
- sophorose has the functionality of suppressing the growth of bacteria that are resident on the skin and that may have a negative effect on the skin (also known as "bacteriostatic"), while promoting the growth of beneficial bacteria that have a positive effect on the skin.
- beneficial bacteria that have a positive effect on the skin include, but are not limited to, Staphylococcus epidermidis, also known as Staphylococcus epidermidis, and Staphylococcus hominis, also known as Staphylococcus epidermidis.
- bacteria that may have a negative effect on the skin include Cutibacterium acnes, known as acne bacteria, Staphylococcus aureus, known as Staphylococcus aureus, Corynebacterium xerosis, known as actinomycetes, and Micrococcus luteus, known as actinomycetes.
- sophorose which has the above-mentioned functionality, is used as an active ingredient, and can therefore be suitably used to maintain the balance of the skin's resident flora and keep the skin in good condition.
- the present invention can be suitably used for the purpose of improving the balance of the resident skin flora.
- the balance of the resident skin flora is disturbed, the excessive proliferation of resident bacteria and the invasion and proliferation of other harmful bacteria occur, inducing various skin symptoms, but the present invention can be suitably used for the purpose of preventing such a state and reducing or suppressing the severity of the symptoms.
- the improvement of the balance can be, for example, increasing the proportion of Staphylococcus epidermidis or decreasing the proportion of Staphylococcus aureus.
- Staphylococcus epidermidis Since Staphylococcus epidermidis has an antagonistic effect against pathogenic bacteria such as Staphylococcus aureus and can inhibit the proliferation of such harmful bacteria, it can function as a balance regulator of the resident skin flora by promoting the proliferation of Staphylococcus epidermidis. Furthermore, the improvement of the balance of the resident skin flora can be, for example, suppressing the proliferation of harmful bacteria such as Staphylococcus aureus without affecting the proliferation of beneficial bacteria such as Staphylococcus epidermidis.
- the present invention can be suitably used for the purpose of keeping the skin slightly acidic and preventing infection by other bacteria and dryness.
- this bacterium breaks down sebum and produces fatty acids that keep the skin slightly acidic and glycerin, a moisturizing ingredient, and produces antibacterial peptides that suppress the growth of pathogenic bacteria, so the present invention can be suitably used for the purpose described above.
- the present invention can be suitably used for the purpose of suppressing the production of toxins from harmful bacteria.
- the bacteria is inhibited from producing toxins, and therefore the present invention can be suitably used for the purpose described above.
- the present invention can be suitably used for the purpose of preventing acne or reducing or suppressing the severity of its symptoms.
- the present invention can be suitably used for the purpose described above.
- the present invention can be suitably used for the purpose of preventing, reducing, or suppressing body odor.
- the present invention can be suitably used for the purpose of preventing, reducing, or suppressing body odor.
