Description

  The present invention relates to a cosmetic, and more particularly to a cosmetic suitable for a warm-sensitive cosmetic.

  Warm sensation cosmetics do not give the skin a cold sensation when spreading the cosmetics, so there is an action that promotes the reach of comfort through treatment, and it is frequently used as an esthetic pack and treatment medium these days. It is like that. Such warming cosmetics include those using the heat of hydration of polyhydric alcohols and those using the reaction heat generated by reacting acid-reactive powders such as magnesium oxide with an acid aqueous solution. Exist. (For example, see Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4) Those using polyhydric alcohol hydration are easy to control the temperature, but the amount of heat generated is limited, and the acid Those using the heat of reaction between the reactive powder and the acid generate a sufficient amount of heat, but because of the reaction between the powder and liquid, there is still room for improvement in the uniformity of the heat distribution. That is, it can be said that development of a warming-imparting cosmetic that can uniformly apply a sufficient amount of heat has been desired.

  On the other hand, cosmetics that are impregnated with a cosmetic material on a support and then applied to an application site are already known, and a technique for packaging a cosmetic material and a support in combination in a packaging form is also known. . (For example, refer patent document 5) The cosmetics used by mixing at the time of use are also known. (For example, refer to Patent Document 6 and Patent Document 7) However, it is a cosmetic packaged in a deformable watertight packaging form with a breakable partition wall and the interior is partitioned into two or more cells. One of the constituent cells is filled with a composition containing an acid-reactive powder, and a different cell is filled with an aqueous composition containing an acid. It is not known at all to mix all the compositions filled in a deformable watertight packaging form and apply the mixture onto the skin.

  The present invention has been made under such circumstances, and an object of the present invention is to provide a warmth-imparting cosmetic that can uniformly impart a sufficient amount of heat.

In view of such a situation, the present inventors have sought for a warming cosmetic that can uniformly apply a sufficient amount of heat, and as a result of earnest research efforts, as a result of destructive partition walls, there are two interiors. A cosmetic that is partitioned into the above-described cells and is packaged in a deformable watertight packaging form, wherein one of the constituent cells is filled with a composition containing an acid-reactive powder, and is a different cell. Is filled with an aqueous composition containing acid, destroys all cell partition walls in use, mixes all the composition filled in the deformable watertight packaging form, and applies the mixture onto the skin The cosmetics were found to have such characteristics, and the present invention was completed. That is, the present invention is as follows.
(1) A cosmetic which is a breakable partition wall and is divided into two or more cells, and is packaged in a deformable watertight packaging form. One of the constituent cells is an acid-reactive powder. The body-containing composition is filled, and an aqueous composition containing an acid is filled in a different cell, and all cell partitions are broken in use and filled in a deformable watertight packaging form. A cosmetic comprising mixing a composition and applying the mixture onto the skin.

(5) The cosmetic according to any one of (1) to (4), further comprising an acid-reactive powder and a hydration heat generating powder.
(6) The cosmetic according to any one of (1) to (5), wherein the hydration heat generating powder is zeolite.
(7) Any one of (1) to (6), characterized in that in application to the skin, the support is impregnated and then the impregnated support is stuck on the skin. Cosmetics described in 1.
(8) The cosmetic according to (7), wherein the support is a non-woven fabric.
(9) The cosmetic according to (7) or (8), wherein the support covers the entire face.
(10) The cosmetic according to any one of (1) to (9), wherein the cosmetic is a pack for esthetics.

  According to the present invention, a warmth-imparting cosmetic that has been made under such circumstances and can uniformly apply a sufficient amount of heat can be provided.

  The cosmetic of the present invention is a cosmetic that is packaged in a deformable watertight packaging form with a breakable partition wall, the inside of which is partitioned into two or more cells, and is one of the constituent cells. A composition containing acid-reactive powder is filled, and a different cell is filled with an aqueous composition containing acid, and when used, all the partition walls of the cell are destroyed and filled into a deformable watertight packaging form. All the compositions prepared are mixed and the mixture is applied onto the skin.

  Here, the deformable watertight packaging form in which the inside is divided into two or more cells by a breakable partition wall is one layer or a thin film of metal such as polyethylene, polypropylene, polyester, polyamide, and aluminum. A material that can freely change its shape according to stress, such as a film in which two or more layers are laminated, and has a water-tight property that does not substantially allow water to pass through is used as a bag-like package. In the processed packaging form, it has a partition that separates the inclusion part from the inclusion part that holds the contents such as cosmetics, and the fillers of the independent parts are mixed with each other by the partition. The structure has no structure, and the strength of the partition is lower than that of the thin film constituting the external packaging form, and the partition is broken by applying pressure to the external packaging form, and the filling is separated by the partition There means packaged forms of structure to be mixable state. As the deformable watertight packaging form, it is preferable to use a so-called laminate film in which two or more metal thin films such as polyethylene, polypropylene, polyester, polyamide, and aluminum are laminated. In addition, the partition uses a thin film in which one layer or two or more layers of polyethylene, polypropylene, polyester, polyamide, etc. having lower strength than the outer layer packaging form are laminated, or the inner packing wall of the outer layer packaging form has an inner filling material. A preferable example is that the layers are not mixed with each other, and are fused and formed at a strength lower than that of the outer package. The number of cells that are independent storage parts for holding the contents generated by such a partition is not particularly limited. This means that if there is one partition, two cells will inevitably occur, but if there are two cells, the composition containing the acid-reactive powder and the aqueous composition containing the acid should be made independent. This is because the objects can be filled and held independently without being mixed with each other. In addition to this, the number of cells can be increased and the number of types of compositions to be made independent can be increased. However, as the number of cells increases, the number of partitions to be destroyed at the time of use increases. The form which has a cell can illustrate preferably.

  In the composition containing the acid-reactive powder filled and encapsulated in one of the cells, the acid-reactive powder constituting the composition includes zinc oxide, magnesium oxide, calcium oxide, aluminum hydroxide, carbonic acid Examples thereof include calcium and magnesium carbonate. Particularly preferred is magnesium oxide. These can be used as they are, or can be contained by performing surface treatment such as silicone treatment, silylation treatment, metal soap coating treatment, phospholipid coating treatment, acylated amino acid salt coating treatment and the like. A preferable embodiment is a form in which a surface treatment is performed, and a silicone treatment can be preferably exemplified as the surface treatment. As a preferred silicone treatment, for example, 0.5 to 10% by mass of hydrogenmethylpolysiloxane is used. A preferable example is a so-called silicone treatment which is diluted with a solvent as required and coated, and then baked at 200 to 400 ° C. for 1 to 72 hours. By performing such treatment, the reaction can be moderated, and thus a temperature preferable for cosmetic treatment such as esthetics can be maintained for a long time. Such acid-reactive powder can contain only one species, or can contain two or more species in combination. Particularly preferred is a form containing magnesium oxide subjected to the silicone treatment. It is particularly preferable that the acid-reactive powder is made of magnesium oxide subjected to the silicone treatment. The preferable content of magnesium treated with silicone in the cosmetic of the present invention is 1 to 15% by mass, more preferably 2 to 10%, based on the total amount of the cosmetic composition in a mixed form at the time of use. % By mass. The preferred content of the acid-reactive powder in the cosmetic of the present invention is 1 to 20% by mass, more preferably 2 to 10% by mass, based on the total amount of the cosmetic composition in a mixed form at the time of use. It is. This is because if the amount of the acid-reactive powder is too small, the amount of heat generated may be insufficient, and if the amount is too large, the temperature may be too high or the temperature distribution may be uneven. is there.

  In the aqueous composition containing an acid filled and encapsulated in one of the cells, the acid constituting this is preferably a water-soluble and solid acid, and particularly preferably a solid organic acid. Specifically, citric acid, malic acid, oxalic acid, tartaric acid and the like can be preferably exemplified, and citric acid is particularly preferable. This is because when a normal mineral acid is used, the reaction rate becomes too fast and the temperature becomes too high. Such an acid can contain only one species or a combination of two or more species. Moreover, it is also preferable to buffer the pH of the composition to 4 to 5 in order to adjust the reaction rate. As a buffering method, there are a method of adding a buffer salt and a method of adding a large amount of acid to partially neutralize the acid, and the latter is preferable in terms of easy pH adjustment. The preferable content of the acid in the cosmetic of the present invention is 5 to 20% by mass, more preferably 10 to 18% by mass, based on the total amount of the cosmetic composition in the mixed form at the time of use. %. Moreover, it is preferable that the alkali added to this for the purpose of a buffer is 2-5 mass% in conversion of potassium hydroxide. It is preferable that the aqueous composition containing the acid filled and encapsulated in one of the cells constituting the cosmetic of the present invention is in a form in which such an acid is dissolved in a carrier mainly composed of water.
