Peel-off type pack cosmetic composition {PEEL-OFF TYPE PACK COSMETIC COMPOSITION}

The present invention relates to a peel-off type pack cosmetic composition, and more particularly, the drying speed is fast after applying the skin, and when the pack is dried, the film discolors from transparent to white, so that the pack removal time can be accurately determined, and at the same time dry film The present invention relates to a peel-off type pack cosmetic composition that can easily remove a dry film without removing foreign matters.

The pack is one of the cosmetics that has been used for a long time. It moisturizes and maintains the skin, cleansing the skin by adsorbing and removing it, and promotes blood circulation to make the skin healthy and beautiful.

These packs can be used not only for the face, but also for the whole body as well as for the neck, shoulders, arms, and legs.They also come in a variety of forms, including jelly, paste, powder peel-off, cream, viscosity, and jelly. The aerosol tissue off or wash off type, the solidification peeling type, the nonwoven fabric gel, the nonwoven fabric impregnated coating type, and the like. Pack products as described above have advantages and disadvantages of each other, and select the appropriate form of formulation according to the consumer's preference.                         

Conventional peel-off pack cosmetics as described above was difficult to determine the pack removal time, usually removed after 15 to 20 minutes after the pack application. However, since the time was also greatly influenced by the thickness (coating amount), temperature, and humidity of the pack agent during application, removal often failed due to insufficient drying.

Accordingly, research has been made on a method of visually informing the user of the drying time of the pack cosmetics. Specifically, Japanese Laid-Open Patent Publication No. 57-48905 discloses a formulation of a phenol-based pH indicator having a discoloring group on an alkaline side. Japanese Patent Application Laid-Open No. 57-58604 discloses a method of blending iron and ions as a base for a pack and blending phenolic hydroxyl groups as a pack cosmetic. Further, Japanese Laid-Open Patent Publication No. 3-93709 discloses a pack cosmetic which is a second agent containing a first agent film-forming agent containing polyoxyethylene dodecyl ether. Japanese Patent Application Laid-Open No. 7-82129 discloses an O / W emulsion coating film-forming pack cosmetic comprising an oil phase and an aqueous phase having a refractive index difference of 0.01 or less, and Japanese Laid-Open Patent Publication No. Hei 10-45531 relates to a method containing a silicone derivative. It is starting.

However, the Japanese Laid-Open Patent Publication No. 57-48905 has a problem in that it is difficult to accurately determine the pack removal time because there is no correlation between the dry state and the pH of the pack cosmetic when applied to the skin. 58604 and Japanese Patent Laid-Open No. 3-93709 have a problem that the drying rate is very slow because the second agent is applied after the first agent is applied as a two-pack pack cosmetic, and the dry film is also difficult to remove smoothly. In addition, Japanese Patent Application Laid-open No. Hei 10-45531 has a problem that the drying time is slow and foreign matters remain when the film is removed by containing a silicone derivative.

In order to solve the problems of the prior art as described above, the present invention is fast drying speed after applying the skin, the film discoloration from transparent color to white when the pack drying can not only accurately determine the removal time of the pack, but also foreign matters at the same time removing the dry film It is an object of the present invention to provide a peel-off type pack cosmetic composition that can easily remove a dry coating without remaining.

In order to achieve the above object, the present invention provides a peel off type pack cosmetic composition, comprising 5 to 30% by weight of polyvinyl alcohol and 1.0 to 50% by weight of silica powder. do.

Hereinafter, the present invention will be described in detail.

The present inventors can accurately determine the removal time of the pack, and while studying a method for easily removing the dried film, as a result of using a mixture of silica powder and polyvinyl alcohol as a film forming agent, the drying rate after skin application After the fast drying, the film of the pack is changed from transparent color to white, which allows the user to accurately determine the removal time of the pack, as well as confirm that the removal of the dried pack is easy, to complete the present invention based on this.

The peel off type pack cosmetic composition of the present invention is characterized in that it comprises 5 to 30% by weight of polyvinyl alcohol and 1.0 to 50% by weight of silica powder.

The polyvinyl alcohol used in the present invention is a water-soluble polymer, a synthetic polymer commonly used as a cosmetic raw material, in particular, a film forming agent in cosmetic raw materials.

The polyvinyl alcohol can be synthesized by polymerization and hydrolysis from vinyl acetate, the polyvinyl alcohol is preferably 86 ~ 89% hydrolysis, when using the polyvinyl alcohol hydrolyzed within the above range at room temperature and high temperature Solubility is maximized, and the amount of some acetyl groups remaining as the polyvinylacetate, which is a synthetic intermediate product, is deacetylated can be reduced.

It is preferable that the said polyvinyl alcohol has a molecular weight of 60,000-100,000, and saponification degree is 86.5-89.9 mol%.

The polyvinyl alcohol is preferably included in the pack cosmetic composition 5 to 30% by weight, more preferably 10 to 20% by weight. If the content is less than 5% by weight, there is a problem in that the strength of the film is significantly lowered and it is difficult to be commercialized, and when the content is more than 30% by weight, the viscosity is very high and the usability is not good.

The silica powder used in the present invention functions to discolor the film coating from transparent to white after applying the pack.

The silica powder is spherical porous powder has an average particle diameter of 6 ~ 9 ㎛, it is good to use a purity of 98% or more.

The silica powder is preferably contained in 1 to 50% by weight, more preferably 10 to 40% by weight in the pack cosmetic composition. If the content is less than 10% by weight, there is a problem in that it is difficult to determine the drying end of the color change from transparent to white at the time of drying, if it exceeds 50% by weight there is a problem that the coating is cracked and the skin pull is very severe.

The peel-off type pack cosmetic composition of the present invention comprising the film-forming agent in which the polyvinyl alcohol and the silica powder are mixed as described above is an oil, water, a surfactant, a moisturizer, a lower alcohol, a metal encapsulant used in a conventional pack cosmetic composition. It is a matter of course that components such as thickeners, pigments, preservatives and fragrances can be used in appropriate amounts.

The peel-off type pack cosmetic composition of the present invention comprising the above components has a fast drying speed after applying the skin, and when the pack is dried, the film discolors from transparent to white, so that the pack removal time can be accurately determined, and at the same time, the dry film is removed. Dry film can be easily removed without leaving foreign matters.

Hereinafter, the present invention will be described in more detail with reference to the following examples. However, the scope of the present invention is not limited to the following examples.

[Example]

Example 1

After dispersing 1% by weight of Sunsil 130 (manufactured by Advanced Chemical) with water-dispersible silica powder at room temperature and heating to 80 ° C, 14% by weight of polyvinyl alcohol and Gohsenol EG (Japan Synthetic Chemical) were slowly added thereto. The mixture was mixed for 30 minutes or more, and uniformly dispersed. 2% by weight of carboxymethyl cellulose, 2% by weight of glycerin-26, 3% by weight of glycerine, 2% by weight of dipropylene glycol, a suitable amount of metal encapsulant, and a residual amount of purified water were added and mixed uniformly to prepare an aqueous phase component. It was.

Then, 7% by weight of ethanol, 0.2% by weight of polyoxyethylene-cured castor oil, 0.1% by weight of polyoxyethylene cholesteryl, and an appropriate amount of sunscreen and a pigment are added to the aqueous phase component, and mixed thereto. 16 0.1% by weight and an appropriate amount of fragrance and preservative were further added to uniformly mix, and then cooled to room temperature to prepare a peel off type pack cosmetic.
