In mass ratios, the shrinking pack cosmetic is obtained from 30-90% of water, 3-65% of albumin, 2-7% of an emulsion base, 0.05-0.3% of a preservative and 0.5-3% of a solvent.

Description

Shrinkable pack cosmetic

The present invention relates to a pack cosmetic having contractility.

Cosmetic packs, also called mask packs, are used by covering the surface of the skin in a film form, and there are types such as a sheet type, a cream type, and a peel-off type. Packs are known to effectively permeate cosmetic ingredients into the skin, and to remove pore dirt and old keratin by blending clay, etc. . If such a pack has physical effects such as shrinkage, it will be possible to penetrate the active ingredient into the skin while tightening tight skin and open pores. It can be expected to produce a beauty effect with immediate effect, which is a big selling point. However, such shrinkable face packs are not currently recognized and cannot be found in the prior art.
On the other hand, JP-A-3-190810 discloses (A) 1 to 20% by weight of a water-swellable clay mineral selected from bentonite, montmorillonite, saponite and hectorite, (B) poly (meth) acrylic acid ester, poly Contains 0.1 to 20% by weight of a synthetic resin emulsion resin selected from vinyl acetate, polyvinyl chloride, polyethylene vinyl and polyisobutylene, and (A) and (B) (as resin) Clay-like pack cosmetics having a blending ratio in the range of 10: 1 to 1: 6 are disclosed. The invention of the same number is used by mixing two components (A) and (B), and is described as having a tension at the time of use, and it is also described that the effect of removing sebum is excellent. Yes. However, there is no description that it is a pack that exhibits contractility, and the component that should provide contractility is not described in the present invention.
Moreover, the method of mixing the two agents is to cause a chemical reaction by mixing the two agents, and cannot be used unless the two components are mixed immediately before packing. Otherwise, problems such as immediate solidification will occur, and it goes without saying that it takes time to mix the two agents. On the other hand, it is not impossible to make a two-component composition into a single agent, but as a guideline for the expected period of use for cosmetics, it can be hardened or deteriorated after being left for a long period of about 3 years. It is not easy to produce a stable pack that does not.

The present invention has been made paying attention to the above points, and the problem is that the pack has the property that it shrinks simultaneously with application to the skin and drying, and the labor of mixing the two agents is reduced. It is intended to provide a shrinkable pack cosmetic that can be used as it is without being required. In addition, another object of the present invention is to provide a one-pack type shrinkable pack cosmetic that has stability that does not harden or deteriorate even when left in a container for a long period of time. That is.

In order to solve the above-mentioned problems, the present invention provides a pack cosmetic that adheres to the skin and contracts, and is 30 to 90% water, 3 to 65% albumin, and 2 to 7% emulsion base material by mass ratio. , 0.05 to 0.3% of a preservative and 0.5 to 3% of a solvent. Each of the above components can be added to the emulsifier and stirred under the required temperature conditions and cooled to obtain the shrinkable pack cosmetic of the present invention. No special manufacturing method is required, and it can be manufactured by a known technique for manufacturing cosmetics. The pack manufactured with the above component ratio makes the skin feel a significant contraction force mainly by the action of albumin.
The present invention also provides 30 to 90% water, 3 to 65% albumin, 2 to 7% emulsion base material, 0.05 to 0.3% preservative and 0.5 to 3 by mass ratio. % Of solvent as an essential component, and further containing 0.1 to 5% clay, 0.0005 to 0.05% APPS, and 0.05 to 1% hyaluronic acid with the total amount as 100%. It is characterized by this. The pack material manufactured with the said component ratio exhibits the remarkable effect which adsorb | sucks and removes the dirt which entered the pore by the effect | action of clay.
Albumin has a property of shrinking with the progress of drying, and constitutes a main component in the pack of the present invention. By controlling solidification accompanying drying, the albumin can be left in a state filled for about 3 years. It shall be stable and will not harden or deteriorate. For this purpose, the amount of components required is 3 to 65% because the shrinkage force is too short when the mass ratio is less than 3%, and the shrinkage force becomes excessive when the mass ratio exceeds 65%. Purified water is used as the water, and the amount is determined in inverse proportion to the amount of albumin. That is, the amount of water is small when the amount of albumin is large, and the amount of water is large when the amount of albumin is small. The lower limit of the component amount is 30%, which is too hard to use as a pack, and the upper limit is 90%, which is too soft.
The albumin is known as a main component of the protein constituting the egg white, and the egg albumin constituting the egg white can also be used in the present invention. By properly preparing a pack agent with albumin as the main component and applying it to the skin, drying and solidification starts with the passage of time, along with the progress of skin shrinkage, dirt entering the pores, Sebum etc. will be excluded. In the present invention, the shrinkage force as a pack agent is required for drying and solidification of albumin, and the long-term stability required for cosmetics is adjusted by so-called additives.
The emulsion base is used to make the pack of the present invention into a cream form, and when the above-mentioned pack of the present invention mainly composed of albumin is applied to the skin, it is easy to spread. Either an oil-in-water type (o / w) or a water-in-oil type (w / o) can be used. The amount of components necessary for the present invention is suitably 2 to 7%. If it is less than 2%, the spreadability is insufficient, and if it exceeds 7%, the spreadability is excessive.
As the above-mentioned emulsion base material, there is a commercially available product that can be suitably used for albumin. Examples include Sepigel 305 (SEPIGEL 305; polyacrylamide, hydrogenated polyisobutene, laureth-7 and water as main components), Simalgel NS ((SIMULGEL NS; hydroxyethyl acrylate / acryloyldimethyltaurine Na) copolymer, squalane. , Polysorbate 60 and water as main components), and Sepinov EMT (SEPINOV EMT10; (based on hydroxyethyl acrylate / acryloyldimethyltaurine Na) copolymer). These are all known as products of Seiwa Kasei Co., Ltd.
In order to impart quality stability to the pack agent, a preservative is necessary, and in the present invention, one or more of methylparaben, ethylparaben, propylparaben, butylparaben, and phenoxyethanol can be freely selected. it can. The component amount of the preservative is required to be at least 0.05%, and when it exceeds 0.3%, it tends to precipitate, so 0.05 to 0.3% is preferable.
A solvent or a humectant is added to the preservative. The solvent or humectant can be freely selected from one or more of butylene glycol, propylene glycol and pentanediol. The amount of the solvent or humectant component depends on the amount of the preservative, but is generally 0.5 to 3%.
The shrinkable pack material of the present invention can take a form to which clay, APPS, hyaluronic acid and the like are added in order to further enhance the cosmetic effect. Clay is said to have a function of adsorbing skin dirt mainly composed of protein, and among them, Okinawa fine particle clay called kukua is suitable. The amount of the clay component necessary for obtaining the effect is 0.1 to 5%. APPS is one of vitamin C derivatives (ascorbic acid-2-phosphate-6 palmitic acid), which is known as a highly osmotic vitamin and is said to have a pore tightening effect. The component amount is suitably 0.0005 to 0.05%. Hyaluronic acid is said to have a moisturizing effect, and an appropriate component amount is 0.05 to 1%. Although not enumerated one by one, in addition to these, components depending on the properties of the product can be added.
Here, an example of a known technique in the production of cosmetics that can be applied in producing the shrinkable pack material of the present invention is as follows. In other words, the required amount of water is added to the vacuum emulsifier and heated, and the above-mentioned emulsion base material, preservative and solvent components are added in necessary amounts, if necessary, and constantly stirred and mixed. While repeating the above, albumin is added in small portions several times and stirred sufficiently so that albumin does not harden. Next, the system is cooled to an appropriate temperature, and further necessary operations such as deaeration and cooling are performed while stirring is continued. The obtained bulk is packaged, packed and shipped after filling the container, but it can also be stored frozen in the bulk and thawed after the fact and shipped.
Since the present invention is constructed and functions as described above, a one-pack type shrinkable pack cosmetic that does not require the trouble of mixing two agents with albumin as a main ingredient can be realized and removed from a package or a container. In addition to being applied to the skin and shrinking at the same time as drying, the pack exhibits the remarkable effect of adsorbing and removing dirt that has entered the pores due to the action of clay. A shrinkable pack cosmetic can be provided. In addition, according to the present invention, it is possible to provide a one-pack type shrinkable pack cosmetic with stability that does not harden or deteriorate even when left in a container for a long period of time. There is an effect.

Hereinafter, the present invention will be described in more detail with reference to examples.

89.8% water by weight, 5% albumin, 3% emulsion base, 2% preservative and 0.2% solvent as main components and blending ratio, lower limit of albumin content It is an example of a near shrinkable pack fee. Purified water as water, egg albumin as albumin, Sepigel 305 (SEPIGEL 305; mainly composed of polyacrylamide, hydrogenated polyisobutene, laureth-7 and water) as emulsion base material, methylparaben as preservative, butylene as solvent Glycol was used.
Purified water is added to the vacuum emulsifier, heated to 40 ° C., methyl paraben added to butylene glycol and heated and dissolved, and then poured into purified water. After adding Sepigel 305, stirring and mixing are performed. Add the entire amount so that it fits the whole. Furthermore, it cools to 30 degreeC, continuing stirring and mixing. After this, stirring with a paddle and stirring with a homomixer are carried out until there is no lumps (uneven small lumps until albumin supplied in powder is completely dispersed), and only paddle stirring is performed, and then deaeration and cooling are performed. The shrinkable pack material was manufactured. The shrinkable pack material of Example 1 obtained was a one-pack type pack cosmetic, so that it could be applied to the skin as it was, and it was excellent in spreadability and took some time to dry. The contractile force could be felt on the skin, and good moisture retention was exhibited.

Optimum albumin content, with 49.8% water, 45% albumin, 3% emulsion base, 2% preservative and 0.2% solvent as the main components and blend ratio It is an example of a shrinkable pack material. As in Example 1, purified water as water, egg albumin as albumin, Sepigel 305 (SEPIGEL 305; mainly composed of polyacrylamide, hydrogenated polyisobutene, laureth-7 and water) as an emulsion base, antiseptic. Methyl paraben was used as the agent and butylene glycol was used as the solvent.
Purified water is added to the vacuum emulsifier, heated to 40 ° C., methyl paraben added to butylene glycol and heated and dissolved, and then poured into purified water. After adding Sepigel 305, stirring and mixing are performed. Is added in small portions in several batches, and the charging and stirring are repeated until it is familiar. Furthermore, it cools to 30 degreeC, continuing stirring and mixing. Thereafter, stirring with a paddle and stirring with a homomixer were carried out until there was no lumps (see above), and finally only paddle stirring was performed, followed by deaeration and cooling to produce a shrinkable pack material. The resulting shrinkable pack material of Example 2 has moderate spreading properties, is not sticky, and dries in about 10 minutes, which is the same as the standard pack material. As the drying progresses, the shrinkage force is applied to the skin. It can be felt and is easy to use as a one-pack type cosmetic pack, and it makes the skin feel a strong contraction force.

The upper limit of the albumin content is 34.8% water, 60% albumin, 3% emulsion base, 2% preservative and 0.2% solvent as the main components and blending ratio. It is an example of a near shrinkable pack fee. As in Example 1, purified water as water, egg albumin as albumin, Sepigel 305 as the emulsion base (SEPIGE 305; polyacrylamide, hydrogenated polyisobutene, laureth-7 and water as main components), antiseptic. Methyl paraben was used as the agent and butylene glycol was used as the solvent.
Purified water is added to the vacuum emulsifier, heated to 40 ° C., butened with methylparaben added to butylene glycol and dissolved in heated water, and sepigel 305 is added, followed by stirring and mixing. In order to prevent the powder from solidifying, it is added in small portions in several batches, and charging and stirring are repeated until the whole is familiar. Furthermore, it cools to 30 degreeC, continuing stirring and mixing. Thereafter, stirring with a paddle and stirring with a homomixer were carried out until there was no lumps (see above), and finally only paddle stirring was performed, followed by deaeration and cooling to produce a shrinkable pack material. The obtained shrinkable pack material of Example 3 is a one-pack type pack cosmetic, and although a slight decrease in spreadability was observed, it showed strong adhesion and was shorter in time than the standard pack material. Dried and felt a strong contraction force on the skin.

This is an example of a form in which clay, APPS, and hyaluronic acid are added in order to further enhance the cosmetic effect using the shrinkable pack material having the main component and blending ratio of Example 2 as an essential component. The clay used was a fine clay from Okinawa called Kucha. 60% of the fine particle clay had a particle size of about 5 μm, and the amount of the component was 3% in terms of the mass ratio, with the total amount of the shrinkable pack material of Example 2 being 100%. The lower of the ranges. The component amount of APPS was similarly 0.01%, and the component amount of hyaluronic acid was also 0.01%. These clay, APPS, and hyaluronic acid were added after the Sepigel 305 was added. Otherwise, the shrinkable pack material of the present invention was produced in the same manner as in Example 2.
The obtained shrinkable pack material of Example 4 is also a one-pack type pack cosmetic, showing properties almost similar to those of Example 2, having an appropriate spreadability, non-sticky, and dry. The time did not change, and the skin felt a strong contraction force. In addition, due to the protein adsorption effect of fine particle clay and APPS, pore dirt was eliminated to an almost inconspicuous level, and it was possible to obtain a moist feeling of skin considered to be due to moisture retention.

In the same manner as in Example 4, it is an example of a form in which clay, APPS, and hyaluronic acid are added in order to further enhance the cosmetic effect with the shrinkable pack material having the main component and blending ratio of Example 2 as essential components. The clay used was also a fine particle clay having a particle size of about 5 μm in 60%, and the amount of the component was 5% by mass with the total amount of the shrinkable pack material of Example 2 being 100%. Both the amount and the component amount of hyaluronic acid are 0.01%. The shrinkable pack material of the present invention was produced by the same method as in Example 2 except that these clay, APPS, and hyaluronic acid were added after the Sepigel 305 was added.
The obtained shrinkable pack material of Example 5 is also a one-pack type pack cosmetic, showing properties almost similar to those of Example 2, having an appropriate spreadability, not sticky, and dry. The time did not change, and the skin felt a strong contraction force. Therefore, due to the protein adsorbing effect of fine particle clay and APPS, pore stains disappeared to an inconspicuous level, and a moist feeling of skin considered to be due to moisture retention could be obtained.
Thus, even though the present invention is a one-pack type shrinkable pack cosmetic, it does not seem to harden immediately without taking a method of causing a chemical reaction by the mixing of two agents to shrink. No troubles occur. Therefore, the shrinkable pack can be used as it is without taking a complicated preparation, taking it out from the package or the container. In addition, according to the present invention, even when left in a container for a long period of about 3 years, which is a standard for the expected period of use, it does not harden or deteriorate. Since the pack agent is provided, this type of pack can be made very easily.
The shrinkable pack material of the present invention is a so-called cream-type pack material, and in the standard specification, drying starts in a few minutes and finishes drying in a few dozen minutes. Can get the feeling that the whole face is tightened. Further, since the shrinkable pack material of the present invention is water-soluble, it can be easily washed away with lukewarm water after finishing the pack, and combined with the one-pack type, is extremely simple to use. .
