Abstract

<P>PROBLEM TO BE SOLVED: To provide a pack cosmetic having the advantages in combination of being easily usable, good in spreadability over and adhesion to the skin and the absorbability of a medicinal active ingredient, and easily peelable. <P>SOLUTION: This pack cosmetic comprises a liquid cosmetic to be applied to the skin and a water-soluble film to be applied to the skin via the liquid cosmetic applied to the skin. In this pack cosmetic, the liquid cosmetic and/or the water-soluble film contain(s) an active ingredient. The liquid cosmetic functions to absorb stains and keratin on the skin. The active ingredient is absorbed into the skin. The water-soluble film functions to promote absorbing the active ingredient into the skin by blocking the liquid cosmetic and adsorb the liquid cosmetic and, after the lapse of a fixed time, is peeled off. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to pack cosmetics, and more specifically, after applying a liquid cosmetic containing an active ingredient having medicinal properties on the skin, a water-soluble film is applied to the skin from above the liquid cosmetic, or Liquid cosmetics are dropped or applied to one side of a water-soluble film and then applied to the skin. The active ingredient is sealed between the skin and the active ingredient is absorbed into the skin, and the liquid cosmetic is soiled. Further, the present invention relates to a pack cosmetic that absorbs keratin and sebum and peels off a water-soluble film adsorbed with liquid cosmetic after a certain time has passed.

As conventional pack cosmetics, there are known a peel-off type in which a liquid cosmetic is peeled after forming a dry film, and a type in which the cosmetic is washed away without forming a film even when the cosmetic is dried (see Patent Document 1 below). In addition, there are an adhesive gel sheet, a skin patch in which skin lotion or the like is immersed in a nonwoven fabric or a woven fabric, and various effects are expected by blending active ingredients (Patent Document 2 described later). reference).
Japanese Patent Laid-Open No. 10-45531 JP-A-9-216808

  However, the peel-off type pack cosmetic has more coating agent components for facilitating peeling from the skin than the active ingredients, and the active ingredient remains in the film when it is formed into a film while drying. When the agent component evaporates moisture and forms a film while drying, the active ingredient evaporates with moisture from the moisture evaporation hole (pinhole) of the film into the outside air, and the active ingredient is absorbed into the skin. There is a problem of reduced promotion. In addition, there is a problem that it is difficult to determine the timing of filming and peeling due to individual differences.

  Washing-type pack cosmetics are more troublesome to wash away than peel-off type cosmetics, and have poor ability to remove keratin, dirt, sebum, and the like. For this reason, it is not used as much as the peel-off type.

  Adhesive gel sheet type pack cosmetics are excellent from the viewpoint of occlusiveness to the gap with the skin, but the familiarity and adhesion of the gel with the skin, adhesion, absorption of active ingredients into the skin, etc. Is still not enough.

  The type in which lotion or the like is immersed in a non-woven fabric or a woven fabric has a problem in adhesion because it has no adhesive force and is peeled off from the skin.

  As described above, all types of conventional pack cosmetics have merits and demerits, and are not satisfactory. In order to solve the above-mentioned problems, the present invention provides a pack cosmetic that can be used easily, has good absorption ability to the active ingredient with stretchability, adhesion and medicinal properties on the skin, and has the advantages of being easily peelable. To do.

  As means for solving the above problems, the pack cosmetic of the present invention comprises a liquid cosmetic applied on the skin and a water-soluble film that is applied to the skin from above the liquid cosmetic applied on the skin. The liquid cosmetic or the water-soluble film contains an active ingredient, the liquid cosmetic absorbs dirt and keratin on the skin, the active ingredient is absorbed by the skin, and the water-soluble film is Sealing the liquid cosmetic material to promote absorption of the active ingredient contained in the liquid cosmetic material or water-soluble film into the skin, and adsorbing and peeling the liquid cosmetic material after a certain period of time. Features. Alternatively, after dripping or applying the liquid cosmetic on one side of the water-soluble film, the water-soluble film is adhered to the skin and brought into close contact with the liquid cosmetic to seal the liquid cosmetic, thereby promoting the absorption of the active ingredient and keeping constant. You may make it peel the water-soluble film which adsorb | sucked liquid cosmetics after progress of time.

  Many active ingredients have problems with stability in an aqueous solvent, and in that case, the active ingredient is previously stretched on a water-soluble film. In this case, it is also possible to include a component A in the liquid cosmetic and a component B or contain it on the water-soluble film side so that the A and B components are chemically reacted during use to express the effect. It is. Moreover, the chemical | medical agent which raise | generates a hydrolysis easily is made to stretch or contain in a water-soluble film so that it may not react with the water solvent in liquid cosmetics.

Since the pack cosmetic of the present invention is a liquid cosmetic applied to the skin and a water-soluble film is applied to the skin from above the liquid cosmetic, it can be used very easily, and it can be stretched and adhered to the skin. Good sex. And since liquid cosmetics are sealed between a water-soluble film and skin, absorption to the skin of liquid cosmetics or the active ingredient in the said water-soluble film is accelerated | stimulated. At the same time, the liquid cosmetic absorbs dirt and keratin on the skin. And since a water-soluble film adsorb | sucks and melt | dissolves the said liquid cosmetics after progress for a fixed time, it peels easily from skin.
At this time, since the water-soluble film is not in close contact with the skin in the portion where the liquid cosmetic is not applied, it is cut only at the boundary between the contact portion and the non-contact portion of the liquid cosmetic, Only the water-soluble film of this part can be easily peeled off. For this reason, unlike the conventional sheet-like pack agent, it is not necessary to use the mold around the eyes and mouth so that the pack agent fitted to each person can be provided.
Moreover, since the water-soluble film sticks to the skin only in the part which the liquid cosmetics contacted, it is easy to concentrate and care about the specific site | part of a wrinkle and a spot. For this reason, the physical makeup of the cover makeup that makes cosmetic points inconspicuous even after the water-soluble film is peeled off by containing or suspending extender pigments, white pigments, white powder, etc. in liquid cosmetics or water-soluble films The effect can be improved.

  The liquid cosmetic composition of the present invention is produced in a conventional formulation as usual, but can be adjusted according to the compatibility with the water-soluble film material, the purpose of use, or the use time. For example, when it is desired to perform the peeling treatment in a short time (within 5 minutes), the melting point temperature of the base material component of the liquid cosmetic is set as high as about 50 ° C. Alternatively, the amount of the high-boiling humectant is reduced, and the liquid cosmetic is designed to solidify quickly when contacted with the water-soluble film. On the other hand, when it is desired to extend the use time, the melting point temperature of the substrate is lowered. Or it can adjust by increasing the usage-amount of a high boiling point moisturizer, or changing the kind of moisturizer.

  The water-soluble film of the present invention is a film that comes into contact with or dissolves in a residual water solvent of a liquid cosmetic and develops adhesiveness or adhesive strength. The water-soluble film is most preferably pullulan or gelatin. The film thickness is preferably 10 to 100 μm, more preferably 20 to 50 μm.

  Various active ingredients are contained or stretched in the liquid cosmetic or water-soluble film.
