The specific embodiment
Cosmetic sheet of the present invention has at lip-deep skin patch of carrier, and wherein skin patch is to form with the wet pressing sensitive adhesive compositions that contains water-soluble polymer and polyoxyethylene sorbitan fatty acid ester.
For cosmetic sheet of the present invention, the polyoxyethylene sorbitan fatty acid ester must ooze out on the surface of skin patch.And the polyoxyethylene sorbitan fatty acid ester is preferably formed stratiform.
For example, as shown in Figure 6, cosmetic sheet of the present invention has the opposite side (opposite side) (skin adhesive side) that lip-deep skin patch 2 and polyoxyethylene sorbitan fatty acid ester at moisture permeable carrier 1 are distributed in the carrier of skin patch 2 unevenly.And, as shown in the figure, the polyoxyethylene sorbitan fatty acid ester is oozing out with carrier facing surfaces part (surface of skin adhesive side), and its part also can be present on this surface with the exfiltrating part 3 of polyoxyethylene sorbitan fatty acid ester.Exfiltrating part (outflow part) is preferably formed stratiform.At Fig. 6, sealing coat is not expressed out, but in some cases, can have sealing coat, so that cover the surface of skin patch 2.
In cosmetic sheet of the present invention, the polyoxyethylene sorbitan fatty acid ester oozes out on the surface of skin patch.Polyoxyethylene sorbitan fatty acid ester layer can be on skin patch by the combined amount of the kind of suitable control water-soluble polymer and combined amount, polyoxyethylene sorbitan fatty acid ester, and/or the kind of inorganic filler and combined amount form.
A kind of method that the polyoxyethylene sorbitan fatty acid ester is oozed out is to mix filler in being used for forming the wet pressing sensitive adhesive compositions of skin patch.Yet as employed filler here, using has the material of good affinity can cause that the polyoxyethylene sorbitan fatty acid ester is difficult to be oozed out to the polyoxyethylene sorbitan fatty acid ester.There is the example of the filler of good affinity to comprise that those demonstrate alkalescence and hydrophilic filler, for example ferroso-ferric oxide, calcium carbonate, aluminium hydroxide and magnesium hydroxide etc. to the polyoxyethylene sorbitan fatty acid ester.Therefore the present invention does not preferably mix these fillers in wet pressing sensitive adhesive compositions.When using these fillers, the less relatively amount of preferred use.On the other hand, demonstrating tart filler is more preferably to use as filler.
By mix filler in wet pressing sensitive adhesive compositions, the skin patch of formation also can be enhanced in moistening and dried mechanical strength.In addition, by mixing filler, also can be shortened in the stickup needed time of after drying.Therefore, when mixing filler, or even under the thicker situation of adhered layer, do not need to resemble the long time the mill run yet.The effect that the reason that dry required time is shortened is estimated to be the interface between filler and water-soluble polymer and the liquid plasticizer is the path of dissipating as moisture.
The common consumption of filler is the water-soluble polymer with respect to 100 weight portions, preferably in 10 to 200 weight portion scopes, and more preferably 25 to 100 weight portions.When the consumption of filler is in 10 to 200 weight portion scopes, skin patch elasticity variation that can not occur forming and the situation that is difficult to well be fit to position to be pasted thus.In addition, the required exsiccant time can not be extended and obtain to paste and be dried after the effect improved of the mechanical strength of skin patch.
As filler, that can mention has inorganic filler and an organic filler, preferably uses inorganic filler.
According to the example of the inorganic filler of composition wet pressing sensitive adhesive compositions of the present invention comprise that silicon dioxide, aluminium oxide, titanium dioxide, titanium are black, white carbon black, iron oxide black, medicinal charcoal, aluminium hydroxide, magnesium hydroxide, calcium carbonate and Talcum or the like.These fillers can be individually or two or more mix and use.Usually, the preferred powder type of employed filler among the present invention.Shape has no particular limits, but considers to obtaining uniform dispersibility preferred spherical.And, preferred 0.01 to the 50 μ m of its particle mean size, more preferably 0.1 to 10 μ m.
For the polyoxyethylene sorbitan fatty acid ester is oozed out, form a kind of in the black and medicinal charcoal of silicon dioxide, aluminium oxide, titanium dioxide, titanium in the preferred filler described above of inorganic filler of wet pressing sensitive adhesive compositions according to the present invention on the surface portion of skin patch.Ooze out through the superincumbent surface portion of polyoxyethylene sorbitan fatty acid ester, the polyoxyethylene sorbitan fatty acid ester that has oozed out on surface portion is easy to contact with the keratotic plug of existence in the pore (pore) when cosmetic sheet and skin adhesive.Because polyoxyethylene sorbitan fatty acid ester and fatty composition be the waste product highly compatible in cholesterol and the pore for example, can show the ability of excellent removal keratotic plug.
Among the present invention, one or more fillers can be selected from inorganic filler described above, and it is mixed that medicinal charcoal and part thereof can be used as pigment.The amount of inorganic filler of being mixed up pigment is with respect to the water-soluble polymer of 100 weight portions, preferably in the scope of 1 to 20 weight portion, more preferably in 3 to 10 weight portion scopes.When the consumption of the inorganic filler of pigment is in 1 to 20 weight portion scope, can form the skin patch that demonstrates good white or black color.
