Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lip pack which is excellent in improving the roughness and dullness of lips and improving the paste of cosmetics such as lipstick. More specifically, the present invention relates to a sheet-shaped lip pack which has a function of easily improving the condition of the lip by applying a sheet-shaped pack containing a polymeric sticking agent and a moistening agent to the lips.

[0002]

2. Description of the Related Art Conventionally, lipsticks and lip creams containing a moisturizer such as polyhydric alcohol and hyaluronic acid have been put on the market for the purpose of improving the roughness of the lips. For example, Japanese Unexamined Patent Publication (Kokai) No. 5-70326 proposes a lip cosmetic composed of a film-forming agent, a wetting agent, oil and fat, and water for the purpose of improving the roughness of the lips. Also, JP-A-61-176
In Japanese Patent Laid-Open No. 512, a lip protecting agent composed of a film forming agent, a wetting agent and a fat and oil wax is proposed.

[0003]

However, the dryness of the air from autumn to winter often causes severe dryness of the lips, and in the moisturizing lipstick type cosmetics represented by the lip cosmetics, There is a problem that the effect is weak to solve this problem, and since the lip protectant has a solution to gel form although the effect is recognized, there is a problem that lipstick cannot be used after application or application. Since it is necessary to remove the coating film, there is a problem that a physical load is applied to the lips when the coating film is removed, and the lips are damaged.

[0004]

DISCLOSURE OF THE INVENTION As a result of intensive studies in view of the above-mentioned circumstances, the present inventors have found that a pack containing a specific polymeric sticking agent and a wetting agent and formed into a sheet having a specific shape. It was found that a lip pack material having a function of easily improving the condition of the lips can be obtained by applying the material to the lips. That is, the present invention is, packages containing carrageenan, and a polymer viscosity agent selected from gellan gum, glycerin, diglycerin, a wetting agent selected from polyglycerin
On the surface of the paint that contacts the lips, use an adhesive resin or
A sheet-shaped lip packing material comprising a child layer and having a mountain-shaped or bow-shaped shape adapted to the shape of the lips.

[0005]

The polymeric thickening agents referred to in DETAILED DESCRIPTION OF THE INVENTION The present invention, affinity for water is stronger, der which have the property of thickening
However , in the present invention, carrageenan and gellan gum are used because carrageenan and gellan gum are excellent in shape retention.
There is . It should be noted, Karagi - Nan and gellan gum the ionic there
Therefore , salts of sodium, potassium, calcium, magnesium, barium, etc. may be formed, and
Each copolymer or mixture may be used.

It is also possible to use an inorganic sticky agent such as smectite, bentonite, organically modified bentonite, silicic acid anhydride or surface-treated silicic acid anhydride together with the above-mentioned polymer sticky agent, but the inorganic sticky agent alone. When used in, the holding power of the shape of the product is weak, which is not preferable.

[0007] as a wetting agent in the present invention, glycerin, diglycerin, since polyglycerol are particularly excellent in the effect of improving the condition of the lip is used.

In the present invention, the sheet form means that the thickness is 10 m.

This product holds the knob (1a) of the holder (1), and on the center line of the lips,
Put the sheet-shaped lip pack material mark (1b) together and paste it 1
Sensory evaluation was performed by sticking for 0 minutes.

Example 4 Using the solution prepared in Reference Example 1, a layer having a thickness of 0.1 mm was formed on a polyester film (thickness: 20 μ) holder, and then cooled to obtain a gel-like sheet-like packing material. Obtained. on the other hand,
The surface of the release paper of the silicone-treated polyester film (one side) was coated with polyvinyl alcohol to prepare a film, and a roller was used so that the sheet pack material and the surface of the silicone-treated polyester film coated with polyvinyl alcohol would adhere to each other. Crimped.
The obtained sheet was punched out into the chevron shape shown in FIG. 4 to obtain the sheet-shaped lip pack material of the present invention. FIG. 4 is a plan view of the sheet-shaped lip pack material of the present invention, in which 1 is a holder, and a gel-like pack material and a release paper are provided on the back side thereof. By peeling off the polyester film which is the release paper at the time of use, polyvinyl alcohol adheres to the surface of the sheet-like pack material, so the surface of the polyvinyl alcohol was attached to the lips for use. This product was sensory-evaluated under the condition of being applied to the lips before going to bed.

Comparative Example 1 Dipropylene glycol 10% by weight, hyaluronic acid 0.
