Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the present invention, in which a powder or the like contained in a bag is swollen by contact with water or hot water, the contents become gel-like, and the cosmetic component elutes out of the bag. With regard to the cosmetic-containing bag which can be used, in particular, as a cosmetic component, by blending a component for bath salt, a component for lotion, or a component for skin cleansing, etc., each component is used for each application while massaging the skin. The present invention relates to a cosmetic-containing bag that can be brought into contact with the skin to obtain a desired effect.

[0002]

2. Description of the Related Art Conventionally, various cosmetics are sealed in a water-permeable bag such as a non-woven fabric and, for example, the cosmetics in the bag are eluted by contacting the skin during use and performing massage or the like. There have been proposed various types of bags containing ingredients (for example, JP-A-3-215414 and JP-A-3-287511).
JP, JP-A-4-49227, JP-A-5-11-11
2443, JP-A-8-154862 and JP-A-11-116461. Most of the conventionally proposed cosmetic-containing bags which can be massaged at the time of use and which contain a gel-like substance, most of them contain a gel-like substance already showing a gel-like state before use. However, when a gel-like substance is contained before use, the volume is large and the weight is heavy, so that the transportation is complicated, and it is not preferable for portable use.

[0003]

Therefore, there is a demand for the development of a cosmetic-containing bag which swells when brought into contact with water or hot water at the time of use, so that the contents of the bag become gel-like. As a polymer that swells when brought into contact with water or hot water and exhibits a gel-like substance, for example, a water-absorbing polymer powder is well known. However, when the water-absorbing polymer powder is introduced into the water-permeable bag and the bag is brought into contact with water or hot water, the water-absorbing polymer powder located on the surface side of the bag that is easily in contact with water or hot water can be easily removed. Although it becomes a gel-like substance, there is a problem in that the water-absorbing polymer powder inside becomes mamako-like and it is difficult to obtain a uniform gel-like substance. Furthermore,
When the water-absorbing polymer powder and the cosmetic component are contained in a bag, and when the water-absorbing polymer powder does not uniformly become a gel-like substance, it is difficult to sufficiently elute the cosmetic component.
Therefore, there is no known commercialized bag containing the water-absorbing polymer powder.

[0004] An object of the present invention is to provide a uniform gel-like substance in a bag without substantially forming a muddy substance by contact with water or hot water at the time of use, and to sufficiently elute desired cosmetics. It is an object of the present invention to provide a cosmetic-containing bag that can be carried out and that allows a cosmetic eluted to come into contact with the skin while performing a skin massage by bringing the bag into contact with the skin. Another object of the present invention is that the contents of the bag before use are solid, such as powder, and become a uniform gel-like substance when brought into contact with water or hot water at the time of use, easy to transport, and portable. Another object of the present invention is to provide an effective cosmetic-containing bag.

[0005]

Means for Solving the Problems The present inventors have intensively studied to solve the above problems. That is, when water or hot water is brought into contact with the water-absorbing polymer substance contained in the bag, usually, the inside is prevented from becoming mamako-like, and a uniform gel-like substance is obtained, and the contents are obtained. A study has been made on a technique for enabling the cosmetic components contained in the composition to be sufficiently eluted. As a result, they have found that such a problem can be solved by incorporating polyethylene glycol powder, and have completed the present invention. According to the present invention, in a water-insoluble water-permeable bag, a solid cosmetic active ingredient, and a water-absorbing polymer powder,
There is provided a cosmetic-containing bag which is mixed with polyethylene glycol powder and is used by absorbing water at the time of use.

[0006]

A bag which is used by absorbing water at the time of use, wherein the bag is mixed with polyethylene glycol powder, and the inside of the bag exhibits a uniform gel-like substance due to the water absorption. Therefore, since the gel-like substance has elasticity, it is possible to massage the bag by bringing the bag into contact with the skin. The cosmetic-containing bag of the present invention can be used for various uses depending on the type of the cosmetic active ingredient to be blended. For example, it can be used for applications having functions such as facial cleansing agents, skin cleansing agents such as body soaps, bath agents, lotions and the like.

The water-insoluble water-permeable bag used in the present invention is water-insoluble and water-permeable, and various components to be incorporated and a gel-like substance obtained by water absorption are substantially released from the bag. Any material may be used as long as it is made of a material having pores that are not formed, and examples thereof include paper, nonwoven fabric, and woven fabric. The use of a nonwoven fabric is preferable so that the dissolution of cosmetic components described below and water absorption are good. The type, shape, size, and the like of the water-insoluble water-permeable bag are not particularly limited, and can be appropriately determined depending on the use, the blending components, and the like.

[0008] The water-absorbing polymer powder used in the present invention exhibits a gel-like state by absorbing water,
Any substance that acts to elute water and the like may be used, and examples thereof include sodium polyacrylate, cross-linked sodium polyacrylate, and a starch / sodium acrylate graft polymer. The mixing ratio of the water-absorbing polymer powder is
It suffices if it can be blended so as to exhibit a gel-like substance when water is absorbed, and to appropriately swell the bag. Usually, it is 1.0-10.0 mass% with respect to all the components mix | blended in a bag.

The polyethylene glycol powder used in the present invention is preferably a polyethylene glycol powder having a molecular weight of 2500 to 10,000. The mixing ratio of the polyethylene glycol powder is the mass ratio with the water-absorbing polymer powder to be compounded, and the ratio of the water-absorbing polymer powder: polyethylene glycol powder is 1: 0.1 to 20, particularly 1: 1 to 1: 1.
10 is preferred. If the blending ratio of the polyethylene glycol powder is less than 0.1 with respect to 1 of the water-absorbing polymer powder, it is difficult to obtain a uniform gel-like substance at the time of water absorption. It takes a long time for uniform swelling, and it takes a long time before it can be used for massage or the like, which is not preferable.

[0010] The cosmetic active ingredient used in the present invention is not particularly limited as long as it is solid, and various ingredients can be used according to its use and desired effects. In this case, the cosmetic active ingredient is not limited to a water-soluble one, and may include, for example, plant powder. As cosmetic active ingredients,
For example, known solid components contained in skin cleansing agents, bath agents, lotions, and the like are preferably exemplified. Combinations and mixing ratios of these components are arbitrary, and can be appropriately selected according to the purpose and use. Preferably, a water-soluble one is used so that the formulated cosmetic active ingredient elutes from the gel-like substance at an appropriate rate by water absorption, and a plant powder from which the active ingredient is extracted with water is used. be able to.

The cosmetic-containing bag of the present invention contains a solid salt and / or a cationized cellulose powder in order to control the swellability of the above-mentioned water-absorbing polymer powder and to obtain a desired gel-like substance. It is preferable to mix them. Examples of the salts include amino acid salts such as glutamate and aspartate; inorganic salts such as carbonate and sulfate; and organic acid salts such as citrate, malate and succinate. Examples of the cationized cellulose powder include o- (2-hydroxy-3- (trimethylammonio) propyl) hydroxycellulose (polyquaternium-10). The mixing ratio of the solid salts and / or the cationized cellulose powder is the mass ratio with the water-absorbing polymer powder to be compounded, and the ratio of the water-absorbing polymer powder: the salt and / or the cationized cellulose powder is 1: 0. 1-20, especially 1: 1
10 is preferred. If the mixing ratio of the solid salts and / or the cationized cellulose powder is out of the above range, it is difficult to obtain a desired effect, which is not preferable. In particular, the use of the cationized cellulose powder can impart a slimy feeling to the gel-like substance obtained at the time of use, and can also improve the feeling of use depending on the application.

The cosmetic-containing bag of the present invention contains, in addition to the above-mentioned various components, various components that can be used in a range that does not impair the object of the present invention or to improve the effects of the present invention and other effects. Can be further blended.

The cosmetic-containing bag of the present invention can be usually packaged in a water-impermeable bag or the like, or in a film or the like, and the package can be peeled off at the time of use to absorb water. Any method of water absorption can be adopted according to the application. For example, when a bath additive component is contained, it can be used by pouring it into bath water. When used as a lotion, after absorbing water to form a gel-like substance, the bag can be brought into contact with the skin, and the lotion component can be eluted and used to massage the skin while looking at the bag. When used as a skin cleanser, the gel can be used to clean the skin at a desired location by grasping the gel-like substance in the hand to the extent that the cleansing component slightly foams.
