Description

  The present invention relates to a skin care composition that can maintain and improve skin health.

Conventionally, various goods have been developed for skin care of various parts of the body such as face care, hand care, foot care and the like. For example, Patent Document 1 discloses a bag-shaped pack article that is used by being attached to a hand.
On the other hand, sanitary masks are widely used as a countermeasure against colds, pollen, infectious diseases, and various types of sanitary masks are sold regardless of the season. For example, Patent Document 2 discloses a preparation for external use in which a semi-solid preparation or a liquid preparation containing a koji-derived component is applied to a mask or the like to prevent the entry of pollen or virus from a gap in the mounting portion. In recent years, the number of people who wear sanitary masks on a daily basis has been increasing every year for reasons other than such hygiene purposes, such as hiding faces without makeup, hiding facial expressions, and worrying about bad breath. There is a tendency.

JP 2014-47140 A Japanese Patent No. 5467678

  By the way, conventionally known skin care compositions have been developed on the assumption that they are directly applied to the skin, and many of them have a good penetration ability into the skin and an idea of supplementing active ingredients for the skin. However, if the aerobic bacteria such as Staphylococcus and Micrococcus that inhabit the surface layer of the human skin can be successfully used without depending on various cosmetic ingredients, the health condition of the skin can be maintained and improved. In addition, excessive use of the skin care composition applied to the skin may give a burden to the skin and may cause a decrease in the regeneration ability inherent to the skin.

The pack article like the above-mentioned patent document 1 is a goods aiming to infiltrate the skin care composition applied to the hand etc. more effectively with a pack effect, and proposes a skin care composition applied to the pack article itself. It is not a thing. Such packs are used for home care at home, and are not configured to be worn on a daily basis or during work.
Moreover, although the external preparation disclosed by the said patent document 2 intends to prevent the entrance | invasion of pollen and a virus by applying to a sanitary mask, the skin care effect cannot be anticipated.

  The present invention has been made on the basis of the above knowledge, and a novel skin care composition capable of maintaining and improving the health condition of the skin by being applied to the skin surface side of a skin contact material such as a sanitary mask. The purpose is to provide.

The composition for skin care according to the present invention is used by being applied to the skin surface side of a skin contact material attached to the skin surface of a human body.
The skin care composition of the present invention is a skin care composition with an unprecedented concept called a skin care composition for application to a skin contact material to be worn on the skin surface of a human body.
According to the skin care composition of the present invention, since skin care ingredients can be supplied from the skin contact material without being applied directly to the skin, the occurrence of skin troubles (dullness, sagging, rough skin, etc.) due to excessive application of cosmetics. There is no fear. Also, since the skin care composition of the present invention may be applied to the skin surface side of the skin contact material that comes into contact with the skin, the method of use is very easy and the skin contact material can be worn in a state of touching the skin. If you do, you are always doing skin care.

In the present invention, the composition for skin care may contain a component that selectively grows useful bacteria in the skin environment.
According to the skin care composition of the present invention, since it contains a component that selectively grows useful bacteria in the skin environment, it is applied to the skin surface side of the skin contact material, and the skin contact material is applied to the human skin surface. If used in a worn state, the normal skin flora can be sounded. Thereby, the glycerin produced by beneficial skin resident bacteria keeps the skin moist and suppresses the growth of undesirable bacteria. Moreover, since it is covered with the skin contact material, the skin surface can be kept in a good moist state, so that drying can be prevented and skin troubles can be improved.

In the present invention, the useful bacterium may be Staphylococcus epidermidis, and the component may be an effective component for the growth of Staphylococcus epidermidis.
According to the composition for skin care of the present invention, Staphylococcus epidermidis that plays a role in protecting the skin grows. Therefore, when used in the same manner as described above, the skin surface of the human body is more effectively cared for.

In the present invention, the effective component for the growth of Staphylococcus epidermidis may be glucooligosaccharide, and the base composed of an oil and fat base may contain the glucooligosaccharide and other components.
According to the skin care composition of the present invention, when used in the same manner as described above, the glucooligosaccharide specifically propagates only beneficial resident bacteria on the skin, and as a result, glycerin produced by the beneficial resident bacteria is produced. Keeps skin moisturized and effectively suppresses fine lines. In addition, the ph value of the skin surface is kept weakly acidic, and the antimicrobial activity is also exhibited by suppressing the proliferation of undesirable bacteria. In addition, since it is based on fats and oils, it is easy to put it into practical use as a cosmetic that can be easily applied to skin contact materials. In addition, the application state can be maintained for a long time. Is done.

In the present invention, the skin contact material may be a sanitary mask.
According to the skin care composition of the present invention, the moisturizing effect of the sanitary mask is synergistic, and the skin care effect is more effectively exhibited. Further, the component does not penetrate into the skin or evaporate, and stays on the skin surface for a long time, and the characteristics are continuously exhibited. Further, skin care is performed while exhibiting the original functions of a sanitary mask such as cold prevention and pollen prevention. In addition, even when a sanitary mask is worn during a fashion sensation or during work, the above skin care effect can be obtained.

  According to the composition for skin care according to the present invention, by applying to the skin surface side of a skin contact material such as a sanitary mask to be worn on the skin surface of the human body, the skin resident flora is made healthy, and the skin Can maintain and improve their health.

It is a schematic perspective view which shows the usage example of the composition for skin care which concerns on one Embodiment of this invention, and shows the state apply | coated inside the sanitary mask. It is an external appearance perspective view which shows the example which embodied the composition for skin care which concerns on one Embodiment of this invention in the stick type cosmetics. It is the table | surface which put together the result of having implemented the efficacy test of the composition for skin care which concerns on one Embodiment which concerns on this invention.

  Hereinafter, embodiments of the composition for skin care according to the present embodiment will be described with reference to the drawings. FIG. 1 shows a state in which a skin care composition 2 according to the present invention is applied to the inner surface 10a side (skin surface side) of a sanitary mask 1 as a skin contact material. The sanitary mask 1 shown in the figure includes a rectangular mask body 10 made of a non-woven fabric and the like, and ear hooks 11 made of rubber strings fixed to both sides of the mask body 10. The mask body 10 is provided with a plurality of pleats 12 extending in the longitudinal direction. When the mask body 10 is attached to the face (not shown) of the human body, the central portion of the mask body 10 is widened in a direction perpendicular to the pleats 12. Is configured to cover the nose. FIG. 2 shows an example in which the skin care composition 2 according to the present invention is used as a stick-type cosmetic, and the stick container 3 is filled with a solid skin care composition 2 produced by the method described later. Has been. The stick container 3 shown in FIG. 2 is a cylindrical container body 30 filled with the skin care composition 2, a cap 31, and a payout for allowing the filled skin care composition 2 to protrude from the upper end of the container body 30. It is comprised by the mechanism part 32. FIG. Reference numeral 33 denotes an operation dial for operating the feeding mechanism portion 32 by hand. In FIG. 2, a cap 31 indicated by a solid line indicates a state where the cap 31 is removed from the container body 30, and a cap 31 indicated by a two-dot chain line indicates a state where the cap 31 is attached to the upper end of the container body 30. The feeding mechanism of the stick container 3 is not limited to the example of FIG.

  When handling the stick container 3 for skin care shown in FIG. 2, the user removes the cap 31 and rotates the operation dial 33 to cause a part of the skin care composition 2 to protrude from the upper end of the container body 30. And the container main body 30 is hold | gripped and it applies so that the protrusion part of the solid skin care composition 2 may be pressed on the inner surface 10a side of the sanitary mask 1 shown in FIG. Thus, the sanitary mask 1 to which the skin care composition 2 is applied is worn around the mouth of the human body by putting the ear hook 11 on the ear. In this wearing state, the skin care composition 2 comes into contact with the skin surface around the wearer's mouth. Since the composition 2 for skin care contains a component that selectively grows useful bacteria in the skin environment, the normal skin flora can be made healthy by contacting the skin surface. Thereby, the glycerin produced by beneficial skin resident bacteria keeps the skin moist, suppresses the generation of fine lines, and suppresses the undesirable growth of bacteria. In addition, since it is covered with the sanitary mask 1 and the skin surface around the mouth is kept in a good moist state, drying is prevented and, for example, a constriction line around the mouth is improved and is less noticeable. can do.

  Formulation examples, production methods, and efficacy tests of one embodiment of the solid skin care composition 2 will be described. First, an oil base is prepared. A solid oil such as carnauba wax, candelilla wax, microcrystalline wax, beeswax, paraffin wax, ozokerite, ceresin wax, etc. and petroleum jelly are mixed uniformly in an appropriate ratio by a hot water bath to prepare a fat base. An appropriate amount of 4 to 6 parts by weight of gluco-oligosaccharide, 4 to 6 parts by weight of xylitol, 0.15 to 0.025 part by weight of fanesole and, if necessary, an auxiliary cosmetic material is blended with 100 parts by weight of the oil base. And after kneading these uniformly, it fills with a container and it is made to cool and solidify.

Here, the gluco-oligosaccharide (α-glucan oligosaccharide) which is contained as a component for selectively proliferating useful bacteria in the skin environment is an oligosaccharide obtained by condensing maltose (starch saccharified starch) and sucrose. . This oligosaccharide specifically propagates only beneficial resident bacteria on the human skin, and as a result, glycerin produced by beneficial resident bacteria keeps the skin moist and keeps ph weakly acidic, which is undesirable. Suppresses bacterial growth.
Ingredients for selectively growing useful bacteria in the skin environment include gluco-oligosaccharides, isomalou oligosaccharides, xylo-oligosaccharides, soybean oligosaccharides, galactooligosaccharides, fructooligosaccharides, dairy oligosaccharides, isomerized lactose, hinokitiol glycosides, etc. Unsaturated fatty acids such as saccharides, α-linolenic acid, arachidonic acid, and γ-linolenic acid, and inorganic salts such as magnesium chloride and magnesium sulfate can also be used.

  Xylitol is a kind of sugar alcohol synthesized from xylose and is a maison compound. The birch resin extract xylitol has a function of forming a stratum corneum excellent in the function of maintaining the moisture of the skin such as amino acids while promoting turnover of the skin surface and promoting metabolism. Farnesol (trimethyldecatriere) is a kind of terpenoid organic compound of linear sesquiterpene, is a colorless liquid at normal temperature and pressure, and has volatility. It is contained in the essential oils of roses, lemongrass or sitoneella, and is one of the ingredients that bring about their fragrance, and is used when making perfume.

  In addition, the solid oil used for the fat base can be employed regardless of whether it is vegetable, animal or mineral as described above, and these may be appropriately selected and used, or a fat base other than the above may be employed. it can. Moreover, main components (xylitol, fanesol) other than the gluco-oligosaccharide added to the fat and oil base are not limited to the above examples. Furthermore, in addition to the above blending examples, a touch improver or the like that suppresses the stickiness may be added. In addition, while the fat base is melted, various cosmetic ingredients such as transdermal absorption accelerators, anti-wrinkle agents, anti-aging agents, moisturizers, antioxidants, vitamins, amino acids, etc. You may mix and knead what is prescribed to have. Further, if necessary, a substance containing an effect such as deodorant sterilization may be formulated. Examples of such substances include epigallocatechin galade (ECGC), a green tea component, antibacterial activity EGCg oil of green tea catechin, polyphenol derived from green tea, and the like. Furthermore, a nasal congestion relieving component, diet aroma component, awakening aroma component, and the like may be added.

Aerobic bacteria such as Staphylococcus and Micrococcus belong to the surface layer of the human skin (especially the face), while anaerobic bacteria such as Acne bacteria exist in the hair follicles and sebaceous glands. Staphylococcus bacteria resident on the skin surface are Staphylococcus aureus and Staphylococcus epidermidis, and Staphylococcus aureus is a typical food poisoning bacterium, but Staphylococcus epidermidis has low pathogenicity and feeds sebum and sweat. Produces weakly acidic fatty acids. Staphylococcus epidermidis produces a sebum membrane and an antibacterial peptide in combination with fatty acids excreted from acne that inhabits the sebaceous glands, keeping the skin surface weakly acidic. Keeping the skin weakly acidic suppresses the growth of Staphylococcus aureus and mold that prefer weak alkalinity. Staphylococcus epidermidis suppresses the number of these bacteria, thereby suppressing bad odors such as free fatty acids, ammonia and indole. Acne gonococci decomposes sebum to produce fatty acids called propionic acid and glycerin. This fatty acid forms a sebum film, absorbs pathogens and other ultraviolet rays, and protects the skin by absorbing ultraviolet rays at a high level, and is essential for human skin care. In this way, Staphylococcus epidermidis and Acne gonorrhoeae that play a role in protecting the skin, but recently, skin resident bacteria not only prevent the entry of pathogens from outside, but are also important for the activation of the host immune system. It became clear that there was. It has been reported that the proper functioning of immune cells in the skin requires signals from skin resident bacteria. In this way, it has been clarified that skin resident bacteria affect the immune response in the same way as intestinal bacteria, and harmony with not only the intestinal bacteria but also the skin resident flora has a major effect on human health and beauty. ing. And the skin resident bacteria which are the skin moisturizing ingredients originally possessed by humans do not decrease or become less effective with aging.
The skin care composition 2 in the present embodiment has been developed to be applied to a skin contact material such as the sanitary mask 1 by paying attention to the above-mentioned points, and of course, various cosmetic ingredients are blended. Although not insane, it differs from a skin care composition for application to the skin. In recent years, point makeup and skin care tend to be more important than excessive makeup, and the skin care composition 2 in this embodiment can be said to be skin care in the era of wearing a sanitary mask for purposes other than hygiene as described above. . That is, skin care can be performed at any time in daily life as long as the sanitary mask 1 is worn as well as at the time of going to bed as described later.
The skin contact material is not limited to the sanitary mask 1 as shown in FIG.
Although not shown, for example, socks, gloves, neck warmers, arm sleeves, supporters to be worn on knees / elbows / thighs, underwear, etc. may be used. For example, if the composition 2 for skin care is applied to the inner surface (skin surface side) of the sock and the sock is worn, the heel and the sole of the foot can be cared for. Among them, the point that the sanitary mask is excellent in the pack effect will be described later.

Next, a test method for the effect of growth of adherent bacteria on the skin and the result obtained using the skin care composition 2 obtained as described above will be described.
<Test method>
When the composition 2 for skin care is applied to the inner surface 10a of the sanitary mask 1 as shown in FIG. 1 and sleeps while the sanitary mask 1 is worn, and when the sanitary mask is not directly worn and applied to the skin. , Staphylococcus epidermidis adhering to the facial cheek was collected, and the change over time of the number of bacteria was measured. The composition 2 for skin care employed 5 parts by weight of glucooligosaccharide, 5 parts by weight of xylitol, and 0.02 part by weight of fanesol with respect to 100 parts by weight of the fat and oil base. In the former case, the sanitary mask was updated daily and a new one was attached.
More specifically, a subject wearing a sanitary mask (46 years old to 55 years old) who applied the skin care composition 2 during sleep in a home bedroom maintained at a temperature of about 18 to 20 ° C. and a humidity of about 40 to 50% by air conditioning. The test was carried out for 7 consecutive days, respectively, on 3 healthy females (aged healthy women) and 3 non-sanitary mask subjects (healthy females aged 46 to 55 years old) who directly applied the skin care composition 2 to their skin.
The medium used was an egg yolk-added mannitol salt stamp medium (surface area: about 10 cm ² ), washed with hot water at a temperature of 30 ° C. for 30 minutes, and then the medium collected from each subject's face and cheeks at 35 ° C. overnight (18-20 hours). ) The increased state of colonies was observed in the cultured medium. FIG. 3 shows the observation results. In FIG. 3, the number of Staphylococcus epidermidis colonies of three subjects on the day before the implementation is averaged to 100, and then the number of Staphylococcus epidermidis colonies after 7 days of continuous use is shown. In FIG. 3, the sanitary mask wearing group is an experimental example, and the sanitary mask non-wearing group is a comparative example.

<Consideration of test results>
From the results of FIG. 3, it was confirmed that the increase in staphylococcus epidermidis for 7 days was significant in the experimental example as compared to the comparative example. Thereby, when the sanitary mask 1 which apply | coated the composition 2 for skin care of this embodiment is mounted | worn, it is understood that there exists a proliferation effect of Staphylococcus epidermidis. As described above, the moisturizing and warming action of the contained gluco-oligosaccharide (useful component) and sanitary mask improves the growth environment of Staphylococcus epidermidis (useful fungus), and the use of useful fungi on the skin surface causes harmful bacteria. It is possible to effectively suppress the growth of the skin, maintain the harmony of the normal skin flora, and maintain and improve the health of the skin. By the way, the percentage of each bacterial species in the skin resident flora is affected by various factors, but in particular, excessive washing and friction, UV stress, drying and low temperatures due to air conditioning, chemicals such as cosmetics, aging If the growth of useful bacteria is hindered by factors such as lack of exercise or sweating, or complex factors, harmful bacteria become dominant and harmony of the skin bacterial flora may be lost, leading to various skin diseases. Therefore, it is very effective for the health of the normal flora of skin to apply a useful ingredient that only useful bacteria can selectively serve as a nutrient to a hygiene mask and attach it to the skin. This is supported by the test results. In addition, by applying useful components indirectly from the skin contact surface by applying to a sanitary mask without directly applying to the skin, the generated sebum easily spreads especially on the surface of wet skin, 4 cm ² per minute. It is also conceivable that there is an effect that it can spread at a high speed and can easily wash the face and avoid excessive friction. And a useful component will remain on the skin surface for a long time without penetrating into a skin and evaporating by apply | coating to a sanitary mask. Also, the skin surface temperature where body heat is dissipated is lower than the deep body temperature, and the comfortable skin temperature is said to be 33-34 ° C. Since the humidity is maintained, the skin surface temperature becomes 35 ° C. or higher, so that the skin resident bacteria become active, and in combination with useful components that are in close contact with the skin, the environment is suitable for the growth of Staphylococcus epidermidis. This is also supported by this result.

  From the above test results, when the sanitary mask 1 to which the skin care composition 2 of the present embodiment is applied is worn and used, the normal skin flora is made healthy, so that the health condition of the skin can be maintained and improved. Therefore, the generation of skin wrinkles and the like can be effectively prevented, and the skin dullness can be effectively improved. That is, if the sanitary mask 1 to which the skin care composition 2 is applied is worn and the mouth and nose are covered, it becomes a packed state, the constriction lines around the mouth are less noticeable, and the lips are rough. Can be improved. In particular, the function of parasympathetic nerves is dominant in the body during sleep, so that metabolism is actively promoted, and growth hormone and nutrition can be distributed throughout the body. Among them, the peak that promotes skin metabolism is said to be between 22:00 and 2 hours, and that the harmony of the normal flora of the skin during sleep is consistent with the use of sanitary masks. Can do. Therefore, by wearing and using the sanitary mask 1 to which the skin care composition 2 is applied at the time of sleeping, it is possible to keep the mouth humidity high, and the effect of suppressing the survival rate of the influenza virus can be expected. If you make it a habit to wear it, you can expect a synergistic effect of skin care and influenza prevention. Furthermore, since the composition for skin care of this embodiment also contains a fragrance component, it is possible to wear a sanitary mask with a refreshing feeling without discomfort.

  In the embodiment, a sanitary mask made of a nonwoven fabric or the like is exemplified as the skin contact material. However, the present invention is not limited to this, and cloth, paper, chemical conversion film, and the like that can be attached to the human skin surface can also be used. Moreover, the structure of the sanitary mask 1 is not limited to FIG. Further, as an embodiment of the skin care composition of the present invention, a solid stick-type cosmetic is illustrated, but it may be semi-solid, and the shape and configuration of the stick container 3 are also limited to the example of FIG. It is not a thing. It is possible to make a cosmetic filled in a stick container 3 spray container, or fill a tube-type or cream-type container as a gel or cream and apply it to the skin contact material with fingers or the like. In these cases, a liquid oil base or a gel oil base is used as the oil base.
