- the duckbill valve 52 is opened and flows into the inner pipe 53 of the cartridge 50.
- the cold water or hot water that has flowed into the inner tube 53 flows into the medicine container 54 through the communication hole 53 c of the inner tube 53.
- the cold water or hot water that has flowed into the medicine container 54 dissolves the medicine in the medicine container 54 and becomes a moisturizing liquid. Then, the moisturizing liquid flows out from the communication hole 53 c into the inner pipe 53 and flows into the flow path 72 from the outlet member 55 through the strainer 57.
- the moisturizing liquid in the flow path 72 is mixed with cold water or warm water flowing in the flow path 71 from the water passage gap 12 c on the downstream side of the switching unit 20 to become a diluted moisturizing liquid. Then, the diluted moisturizing liquid is discharged from the sprinkling holes 16.
- the hole is not formed in the wall of the valve chamber 51b, if the volume of the shower cosmetic 100 is reduced by dissolution, cold water and hot water that have entered the medicine container 54 through the communication hole 53c are reduced in volume. A turbulent flow is formed around the later shower cosmetic 100, and the shower cosmetic 100 after the volume reduction is lifted. For this reason, even if a hole is not formed in the wall of the valve chamber 51b, the shower cosmetic 100 is appropriately dissolved and flows out from the communication hole 53c.
- a normal shower that does not include the moisturizing liquid and a shower that includes the moisturizing liquid can be obtained by the selection operation of the first and second operating members 45 and 48.
- the inner diameter of the inner tube 53, the size and number of the openings of the communication hole 53c, the arrangement position, and the like are set so that a moisturizing liquid with an appropriate concentration can be obtained. If it does in this way, the cosmetics 100 for showers will be scraped off little by little by the cold water or warm water which flowed in the chemical
- a space 101 is formed on the downstream side of the shower cosmetic 100, and an interval is formed between the upper end of the shower cosmetic 100 and the strainer 57.
- the strainer 57 bulges downstream. It is formed in a shape. Therefore, a relatively large particle peeled from the shower cosmetic 100 moves so as to fluctuate due to the water flow on the upstream side of the strainer 57. For this reason, it can prevent that such a granular material adheres to the inside of the strainer 57, and a flow path is blocked.
- the shower cosmetic 100 contains a PEG / PPG copolymer as an essential component, it can exhibit a certain solubility while suppressing its solubility in cold water or warm water. Moreover, since the shower cosmetic 100 contains PVA, the solubility in warm water is particularly enhanced. Furthermore, the moisturizing agent as a beauty agent can improve the moist feeling of the skin after taking a shower.
- a humectant is used as the medicine stored in the cartridge 50.
- the medicine contained in the cartridge 50 is not limited to this, but is a perfume, a slimming agent, other cosmetic additives such as whitening lotion, antiperspirant, acne, atopy, and a dermatological drug. May be.
- medical agent was used, the shape and form of a chemical
- a gel-like or particulate drug may be used.
- the duck bill valve 52 is provided in the cartridge 50 so that the water does not flow into the cartridge 50 when only water is sprayed from the shower head 10.
- the check valve that prevents water from flowing into the cartridge when only water is sprayed may have a configuration other than the duckbill valve 52. Further, when only water is sprayed, if the solution in which the medicine is dissolved in the cartridge 50 does not flow out, the water may flow into the cartridge 50.
- the shower cosmetic of the present embodiment was configured to include a PEG / PPG copolymer as an essential component.
- a PEG / PPG copolymer as an essential component.
- the shower cosmetic was further configured to contain PVA.
- the solubility of PVA in water varies depending on the temperature, and the solubility in hot water is higher than that in cold water. Therefore, the solubility of the entire cosmetic for shower with respect to cold water or hot water can be adjusted by adjusting the addition amount of PVA. Moreover, the swelling property of the cosmetic for shower can be suppressed by adding PVA.
- the shower cosmetic is further configured to include a cosmetic agent. Therefore, effects such as moisturizing property, deodorizing property, antiperspirant property, antiseptic property and the like based on the beauty agent can be exhibited while maintaining appropriate solubility of the cosmetic for shower in cold water or hot water.
- the PEG / PPG copolymer, the PVA, and the beauty agent were uniformly dispersed and solidified at room temperature. As a result, these components can be uniformly eluted during use.
- the mass ratio of PEG to PPG in the PEG / PPG copolymer is (150 to 200) / (35 to 70). In this case, it is possible to improve the sustainability by suppressing the solubility of the cosmetic for shower in water and warm water.
- the PVA is a partially saponified PVA having a saponification degree of 86 to 90 mol%.
- the content of the PVA is 0.7 to 15% by mass. As a result, it is possible to reduce the possibility that the shower cosmetic agent swells when touched with cold water or hot water when the shower cosmetic agent is used.

Abstract
Description
PEG/PPG共重合体は、分子中にポリオキシエチレングリコール(ポリエチレングリコール)単位とポリオキシプロピレングリコール(ポリプロピレングリコール)単位とを有し、ノニオン界面活性剤であって、保湿効果を有する。シャワー用化粧剤に用いられるPEG/PPG共重合体としては、常温で固体であるものが好適である。 (PEG / PPG copolymer)
The PEG / PPG copolymer has a polyoxyethylene glycol (polyethylene glycol) unit and a polyoxypropylene glycol (polypropylene glycol) unit in the molecule, is a nonionic surfactant, and has a moisturizing effect. As the PEG / PPG copolymer used in the cosmetic for shower, those that are solid at room temperature are suitable.
PEG/PPG共重合体としては、下記のものを挙げることができる(数字は質量比を示す)。 The copolymerization ratio of PEG and PPG in the PEG / PPG copolymer is not particularly limited. Therefore,
Examples of the PEG / PPG copolymer include the following (numbers indicate mass ratio).
PVAは、多数の水酸基を有することから、非常に強い親水性を有し、特に温水に可溶という特性がある。従って、シャワー用化粧剤にPVAを配合することにより、特に35℃以上の温水に対するシャワー用化粧剤の溶解性を高めることができる。 (PVA)
Since PVA has a large number of hydroxyl groups, it has a very strong hydrophilic property and is particularly soluble in hot water. Therefore, by adding PVA to the shower cosmetic, the solubility of the shower cosmetic particularly in warm water of 35 ° C. or higher can be enhanced.
ここで、PVAの重合度はm+n、ケン化度はm/(m+n)で表される。 -[CH 2 -CH (OH)] m- [CH 2 -CH (OCOCH 3 )] n
Here, the polymerization degree of PVA is represented by m + n, and the saponification degree is represented by m / (m + n).
美容剤としては、コラーゲン、セラミド、プラセンタ、各種ビタミン(ビタミンC、ビタミンE等)、天然香料、合成香料、調合香料(フレグランス等)、油剤、保湿剤、香料、消臭剤、制汗剤、色素、防腐剤、乳化剤、アミノ酸、水等を挙げることができる。美容剤の種類は限定されるものではなく、公知のものを使用してもよい。 (Beauty agent)
Beauty agents include collagen, ceramide, placenta, various vitamins (vitamin C, vitamin E, etc.), natural fragrances, synthetic fragrances, formulated fragrances (fragrances, etc.), oils, moisturizers, fragrances, deodorants, antiperspirants, Examples thereof include pigments, preservatives, emulsifiers, amino acids and water. The kind of beauty agent is not limited, You may use a well-known thing.
その他の添加剤成分としては、粘度調整剤、賦形剤等が適宜選択して用いられる。 (Other additive components)
As other additive components, viscosity modifiers, excipients and the like are appropriately selected and used.
シャワー用化粧剤を構成するPEG/PPG共重合体は、シャワー用化粧剤の主成分であって、シャワー用化粧剤中に80~97質量%含まれることが好ましい。このPEG/PPG共重合体の含有量が80質量%を下回ると、冷水や温水に対するシャワー用化粧剤の適度な溶解性を得ることが難しく、また保湿性を得ることも難しくなる。一方、PEG/PPG共重合体の含有量が97質量%を上回ると、PVAや美容剤の含有量が相対的に減少し、それらの成分に基づく効果が得られず、好ましくない。 (Composition of cosmetic for shower)
The PEG / PPG copolymer constituting the shower cosmetic agent is a main component of the shower cosmetic agent, and is preferably contained in an amount of 80 to 97% by mass in the shower cosmetic agent. When the content of the PEG / PPG copolymer is less than 80% by mass, it is difficult to obtain appropriate solubility of the cosmetic for shower in cold water or hot water, and it is difficult to obtain moisture retention. On the other hand, when the content of the PEG / PPG copolymer exceeds 97% by mass, the content of PVA and the cosmetic agent is relatively decreased, and an effect based on those components cannot be obtained, which is not preferable.
