Abstract

PURPOSE:To obtain a rapid-drying pack cosmetic having high viscosity, by adding a component selected from xanthan gum, scleroglucan and aureotium to a pack composed of polyvinyl alcohol, a resin latex emulsion, water, a humectant and powder. CONSTITUTION:The objective pack cosmetic can be produced by compounding (A) a pack containing a polyvinyl alcohol, a resin latex emulsion, water, a humectant and powder as essential components with (B) xanthan gum [polysaccharide produced by Xanthamonas (a phytopathogenic bacterium)], scleroglucan [polysaccharide produced by Sclerotium which is produced by Chilferry, USA) or aureotium (polysaccharide produced by Aureotium). The amount of the component B is preferably 0.05-5wt% based on the whole pack cosmetic. In spite of high viscosity, the pack cosmetic has excellent spreadability, gives well- finished skin and is peelable easily.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to bag cosmetics, and more particularly to improved pack cosmetics with high viscosity and quick drying properties.

Conventional technology Conventionally, back cosmetics are cosmetics that are applied to the skin, dried for 20 to 30 minutes to form a film, and then peeled off. It is preferred because of its good quality. However, for general consumers, it is very inconvenient and troublesome to keep the applied pack as it is for more than 20 minutes without changing facial expressions, and it is difficult to wait for too long. We hear from many consumers that they would like to use bag cosmetics as they have excellent effects if they can be used without them. For this purpose, it is necessary for the back cosmetics to have the function of quick drying, so many researchers
I've been working on this problem. For example, if you increase the amount of polyvinyl alcohol, resin latex emulsion, powder, etc., quick drying properties will increase, but in general, ingredients that have the property of increasing drying properties have compounding limits in terms of usage characteristics, stability, etc. At present, a user-friendly pack that dries quickly within 20 minutes has not yet been developed.

Problems to be Solved by the Invention In view of the current state of the conventional bag cosmetics mentioned above, the present inventors have conducted extensive research to solve the above drawbacks. By blending xanthan gum, scleroglucan, or aurelotium into a bag cosmetic containing It was discovered that cosmetics can be obtained, and the present invention was completed based on this knowledge.

That is, according to the present invention, xanthan gum and scleroglucan are added to a pack containing polyvinyl alcohol, resin Latinx emulsion, water, moisturizer, and powder as essential ingredients. A bag cosmetic containing one or more of Aurelotium and Aurelotium is provided.

According to the present invention, xanthan gum, scleroglucan, or aurelotium can be further added to the formulation of conventional bag cosmetics containing, for example, polyvinyl alcohol, resin latex emulsion, water, and powder, so that the formulation can be applied even though it has a high viscosity. It is possible to obtain a bag cosmetic that has good properties and dries quickly.

The polyvinyl alcohol that can be used in the bag cosmetic of the present invention may be any polyvinyl alcohol as long as it has a high film safety.
Any conventionally used material can be used. Such polyvinyl alcohol has a polymerization degree of 5.
00 to 2000 is preferable, and there is no particular limitation on the amount, but preferably based on the total weight of the bag cosmetic,
It is preferable to blend in the range of 5 to 20% by weight, more preferably 7 to 15% by weight, since a product with good usability can be obtained.

The resin latex that can be used in the bag cosmetic of the present invention can be any conventionally used resin latex. Examples of such resin latex include commercially available polyvinyl acetate emulsilon and Vinipran S-4.
0 (Nissin Chemical Co., Ltd.), Bonko 2580 (Dainippon Ink), natural or synthetic isoprene latex, Maxprene IR-900 (Steel Chemical Industry Co., Ltd.), and polyacrylate resin emulsion.

One or more of these can be arbitrarily selected and used. There is no particular limitation on the amount of resin latex emulsion blended, but the preferred amount is 5 to 5.
It is in the range of 0% by weight.

Powders that can be used in the cosmetic pack of the present invention include:
It can be any conventionally used one. Examples of such powders include kaolin, talc, titanium oxide, aluminum silicate, iron oxide, zinc white, and mica. One or more powders may be arbitrarily selected from these powders and used. There is no particular limitation on the amount of powder blended, but it is preferably selected in the range of 1 to 30% by weight.

According to the present invention, xanthan gum, scleroglucan, or aurelotium is blended into a bag cosmetic containing the above-mentioned general ingredients. Here, "xanthogum" refers to a polysaccharide that produces a plant pathogenic bacterium called Xanthoa+-onas, and "scleroglucan"
"Aurelotium polysaccharide" is a polysaccharide produced by the Sclerotium fungus created by American scientist Kilferry.
refers to a polysaccharide produced by the fungus Aurelotium. There is no particular limitation on the amount of xanthan gum, scleroglucan, or aurelotium, but it is preferably added in an amount of 0.05 to 5% by weight based on the total weight of the cosmetic pack, and more preferably in order to further improve usability and stability. 0.1-2% by weight from the surface
It is blended. If the amount of these ingredients is too small, the desired effects of improving high viscosity and quick drying properties tend to be insufficient, while if the amount is too large, it becomes difficult to dissolve. xanthan gum,
Scleroglucan and aurelotium can be commercially available products. For example, as xanthan gum, Keltrol (Koei Kogyo) can be suitably used, and as aurelotium, Zanflow and Zancort manufactured by American Kelco Co., Ltd. can be mentioned.

In addition to the above-mentioned ingredients, the bag cosmetic of the present invention may contain a moisturizing agent, a surfactant, a pigment, an alcohol, a fragrance,
Preservatives and the like may be included as long as they do not impair the purpose of the present invention.

Effects of the Invention The bag cosmetic according to the present invention spreads well when applied despite its high viscosity, has a good finish, and has excellent drying properties, and has other usability. It has the properties required as a pack cosmetic, such as ease of peeling and long shelf life.

EXAMPLES Hereinafter, the present invention will be explained in more detail with reference to Examples, but it goes without saying that the scope of the present invention is not limited to these Examples. In addition, the compounding amount in each side below is weight%.

(The following is a blank space) (Method 11) After stirring and dissolving the above components (1) to (2), components (1) to (0) were added thereto, and component (2) was added as a dispersant. Next, after checking the dispersion state, add ingredient ■■ to make it disperse and swell.
This was stirred and dissolved at 80°C, and after melting, a mixture of component 0@ was added to a portion of component (1), and the mixture was stirred until it became homogeneous. It was cooled to 30°C to obtain a bag cosmetic.

(Evaluation test results) Take an appropriate amount of each pack cosmetic of Examples 1 to 3 and Comparative Example 1 on your fingertips and apply it thinly to the cheek area of the facial skin. Drying time, finish after drying, and temperature conditions depending on pack aging (0℃
, room temperature and 40°C). The results were as shown in Table 1 below.

(Leaving space below) Table 1 Examples Examples Examples Comparative Example Items 1231 Ease of application Good Good Good Difficult finish
Good Good Good Uneven drying time (min) 15 10 7 11 Stability Good
Good Good Gelation As is clear from the results in Table 1, the pack cosmetics of Examples 1 to 30 were easy to apply, had a good finish, and had a fast drying rate. On the other hand, Comparative Example I had a fast drying speed but had a high viscosity, which made it difficult to apply and gave an uneven finish, which was not preferable. From these results, it is clear that the viscosity of the back cosmetic increases by adding Keltrol, but on the contrary, the ease of application and finish improve.

(Manufacturing method) After stirring and melting the above ingredients ■～■, add ingredients ■～＠, and then add ingredient ■■ while dispersing it. 6 After checking the dispersion state, add ingredient ■■ and let it swell in dispersion. The mixture was stirred and melted at 80° C. After melting, a mixture of component ◎ [phase] was added to a portion of component (◎), and the mixture was stirred until uniform. This is 3
The mixture was stirred and cooled to 0°C to obtain a pack cosmetic.

(Evaluation results) Evaluations were made in the same manner as in (Evaluation results). The results were as shown in Table 2.

(Left below) Table 2 - Ease of application Good Good Good Good Difficult finish
Good Good Good Good Uneven Drying time (minutes) 91010910 Stability Good Good Good Good The gelling Examples 4-70 pack cosmetics were similar to those in Examples 1-3, easy to apply and dry well. I confirmed that it was fast. Conventionally, in order to speed up the drying speed, it was necessary to use a system with a high molecular weight or a large amount of powder, but in that case, the viscosity inevitably became high, making it difficult to apply, and the finish was also poor. There was a trade-off phenomenon in which the stability was also significantly deteriorated. On the other hand, by adding xanthan gum or the like to the pack cosmetic according to the present invention, the viscosity of the pack cosmetic increases, but on the other hand, it becomes easier to apply.
It was confirmed that a functional, quick-drying pack cosmetic with a good finish could be obtained.
