Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a sheet-shaped cosmetic composition, and more particularly, it is easy to handle and has good usability, and it can be applied to the skin. The present invention relates to a sheet-shaped cosmetic composition having excellent moisturizing effect, whitening effect, ultraviolet ray preventing effect, slimming effect, tightening effect, and wrinkle removing effect on a site.

2. Description of the Related Art As skin cosmetics, various types of products such as lotions, creams, emulsions, packs and foundations have been put on the market.

Most of the cosmetics are liquids or semisolids, but in recent years, some pack-type cosmetics have been proposed. For example, there is a pack agent composed of polyvinyl alcohol or polyvinyl alcohol and / or polyvinylpyrrolidone. For example, a molded product having a predetermined shape can be used by sticking it on the skin, or a semi-solid product can be kneaded from a tube and used for facial treatment. There is a formulation that removes dirt and other substances on the stratum corneum by peeling it off after applying it to the skin and drying it.

Further, after applying the pack agent to the skin, the dirt and the like of the stratum corneum are removed by washing the pack agent together,
Formulations that keep the skin healthy are also on the market.

[0005] Among these cosmetic preparations, the pack has various effects by not only peeling the old stratum corneum of the skin and activating the skin but also incorporating various medicinal components into the pack. It is expected to have an effect.

The effects of the pack are as follows: smooth skin, moisturize skin, enhance skin moisturizing effect, protect whitening effect and ultraviolet rays, tighten skin, slimming effect, etc. Is expected.

[0007] As a method of using these packs, a method of kneading a semi-solid preparation from a tube and directly applying it to the skin with a hand or the like is generally used, but it takes a lot of time to apply it, and the pack is used by a finger. From problems such as sticking to
BACKGROUND ART Packs in the form of being provided with a release sheet, molded into a sheet, and having an adhesive surface attached to the skin have been commercially available.

[0008]

However, these conventional patch-type packs, which are made of water-insoluble preparations, cannot be washed away.

Further, the conventional packs have a problem that if the skin is wet when the pack is applied to the face or the like, the moisture makes it difficult to adhere to the skin.

By the way, it is possible to use a water-soluble film as one means for solving these problems, but when sticking a water-soluble film to the skin, the issue is how to obtain the adhesiveness to the skin. However, in that case, two methods of conferring tackiness on the film itself or pre-wetting the skin and attaching a water-soluble film can be considered. As a method for imparting tackiness to the film itself, a suitable plasticizer may be added to make the film, but it is practically very difficult to hold the tacky film by hand and attach it. In the method of pre-wetting the skin and pasting the water-soluble film, the film pasted on the skin does not always adhere to the skin, so it peels off immediately or moves on the skin surface, resulting in poor usability. It was of low practicality.

Therefore, it is an object of the present invention that the sheet can be used especially by sticking it to wet skin, and can be peeled off after continuing sticking, and can be easily washed off with water, which is extremely excellent in usability. The present invention is to provide a cosmetic composition.

[0012]

Means for Solving the Problems Accordingly, the present inventors have:
As a result of intensive investigations to solve the above problems, by using a water-soluble non-woven fabric or woven fabric as the form of the cosmetic material, it can be firmly adhered simply by sticking it to wet skin, and then also peeling off. They have found that they can be washed off, and have completed the present invention.

That is, the present invention provides a sheet-like cosmetic composition comprising a water-soluble non-woven fabric or woven fabric.

[0014]
