Description

[Detailed Description of the Invention] [Field of Application of Shisangyo-1]] The present invention relates to a useful cosmetic for skin care, and more specifically to a cleansing product that can easily remove skin wastes, deposits, etc. The present invention relates to an excellent skin care cosmetic that has a pine surge effect as well as a good sensation on use.

[Prior Art] In general, skin cleansers include creams, lotions, and lotion-type cleansers that utilize the detergency of surfactants and the solvent action of bases to remove skin waste and dirt. Cleansing agents are available and have been used. Washing powders have also been used that utilize the adsorption and frictional effects of vegetable powders such as rice bran and starch, and mineral powders such as kaolin and bentonite.

Conventionally, the purpose of promoting such washing or cleansing effects even more strongly, or at the same time, promoting blood circulation in the skin,
Various skin cleansers 1 have also been developed that have been modified to have a pine surge effect that activates the metabolism.

Inorganic, organic, or vegetable insoluble solid particles are used in this type of cleaning agent. 5L131512), and specific hard synthetic resins as organic powders (Special Publication No. Sho Go-4220).
3), specific synthetic polymer/' powder) K (Unexamined Patent Publication Il
? 458-192814), as well as oat flour (Japanese Patent Application Laid-Open No. 50-53542) as a vegetable powder, as well as techniques and commercially available products that incorporate apricot shell grains, walnut shell grains, coarse almond powder, etc. It is listed in and is well known.

Furthermore, in addition to the above-mentioned insoluble solid particles, a technique in which living plant cell wood grains or soft exfoliated fine powder such as foamed urethane is mixed into the cosmetic base (Japanese Patent Publication No. 52-28857, Japanese Patent Application Laid-Open No. 51-44649) (No. 2, etc.) and beading-type skin beautifying materials whose main base material is polyvinyl alcohol.

[15? ! By the way, the cleaning agent containing the above-mentioned insoluble solid particles has the cleaning effect of the base material as well as the physical scrubbing action and adsorption action of the particles during use, and has a pine surge effect. However, it is useful because the cleansing effect is enhanced.

In the past, most products were made from this perspective. However, these products are made by dispersing single insoluble solid particles with a certain size, and if the particle size becomes large, it will cause an uncomfortable feeling on the skin, and if it is hard, it will cause discomfort during use. I felt some pain, so it was a no-brainer. Therefore, in order to solve this problem, various efforts have been made to select the particles to be mixed, and one such attempt has been to formulate granules whose particles slowly dissolve or disintegrate during use.

In addition, as a specific example using the above-mentioned insoluble solid particles A,
There is a cosmetic pine surge cleaning material in which granules obtained by pulverizing living cells such as leaves, roots, fruits, and stems of plants are mixed into a cosmetic base. This technology uses living cell wood, so it can be expected to have a cleansing and pine surge effect without damaging the skin's integrity. It is difficult to store for a long period of time, and it is not suitable for mass production and stable supply, so it is not completely satisfactory.

Furthermore, the beading-type skin beautifying material, which is mainly based on polyvinyl alcohol, is used on the skin surface and rubbed off, which causes the film to break up into small pieces, twist, and peel off, thereby removing lrj stains on the skin. It is something. However, in this case, the adhesive is strong and requires a strong force to be rubbed off, resulting in a negative 111% effect on the skin, which is not necessarily preferable in terms of skin irritation.

Therefore, it has been desired to develop a skin cleansing material that is comfortable to use and has cleansing and pine surge functions.

[Means to solve the problem] As a result of intensive research in view of the above circumstances, unexplored town names, etc. have been shortened to m.
By mixing a hydrophilic powder and a water-insoluble polymer to form an aggregate, and by blending the coarsely ground aggregate into an aqueous base, it has a good feeling of use and has cleansing and pine surge effects. It has been found that an excellent skin care material can be obtained. Furthermore, it has been found that by blending a coarsely pulverized agglomerate obtained by mixing a solid oil agent in addition to the above-mentioned components into an aqueous base, an even more excellent cosmetic for skin application can be obtained. Based on these findings, we completed the Unreleased 11.

That is, the present invention provides a skin care cosmetic prepared by dispersing a coarsely pulverized aggregate of short m fibers, a hydrophilic powder, and a water-insoluble polymer in an aqueous agent, and furthermore, a skin care cosmetic prepared by dispersing a coarsely pulverized aggregate consisting of short m fibers, a hydrophilic powder, and a water-insoluble polymer, and furthermore, The present invention relates to a skin care cosmetic prepared by dispersing coarsely pulverized aggregates blended with a solid oil in an aqueous base.

The configuration of the present invention will be explained below.

As short fibers used in the present invention, generally known short fibers can be used as long as they can be made by humans.For example, cellulose-based, polyester-based, polyamide-based, polyacrylonitrile-based fibers, more specifically, Examples include synthetic fibers such as rayon, acetate, nylon, tetron, and acrylic, and natural lams such as sheep t-shirt and silk fibers.One or more of these may be selected and blended as necessary. These fa males are preferable because they have good water dispersibility and feel, and for the present invention, #a fibers with a length of about 0.2 to 10 m5 and a thickness of 0.5 to 5 deniers are preferred. If it is of this level, it can be easily adjusted, it can be expected to have a flexible and soft feel when used, and it is easy to handle, so it is preferable.

The hydrophilic powder used in the present invention is an organic or inorganic powder that is insoluble in water and has good affinity with wood. For example, starch, crystalline cellulose, silk powder, etc. Inorganic powders include kaolin, montmorillonite crystalline minerals, or inorganic powders such as calcium carbonate, calcium phosphate, aluminum silicate, magnesium silicate, magnesium sulfate, magnesium carbonate, and silicate aluminum magnesium. It is. These hydrophilic powders form appropriate voids and have a soft feel when combined with the short fibers described in +iii. The moisture content of the coarsely ground material can be increased, giving it a fresh feel.I7. This will improve the feel of the product. It is also used for dispersibility in aqueous systems and stability F-7.The parent tree JIJ1 powder tj'' is selected from one or more types as appropriate depending on its use 1.1.5. Can be mixed.

Further, in the present invention, a binder of -1-2 short fibers and hydrophilic powder and 1. Examples of water-insoluble polymers used include water-resistant, water-insoluble +1 binders, etc. Anything can be used as long as it functions properly. That is, since the present invention is ultimately made into an aqueous base, a polymer that dissolves in an aqueous system is not suitable for achieving the purpose. Specific examples of water-insoluble polymers include vinyl acetate-based and acrylic-based polymers and copolymers, and resin emulsions of these are easily available and can be suitably used in the present invention.

The coarsely pulverized aggregate of the present invention is basically composed of the components listed in 1iif above, but it is more preferable if a solid oil is added as a binder. The skin care cosmetic of the present invention can be rubbed off after application to obtain a cleansing effect, but water-insoluble polymers alone tend to have strong binding properties and become hard, and the high molecular weight When the amount decreases, it tends to be divided into small pieces when used. Therefore, by further adding a solid oil agent, it is possible to prevent the skin from being shredded into pieces smaller than a certain size, and it is possible to remove skin wastes and dirt as if they were covered or contained. In addition, solid oil agents do not give a sticky feeling to the skin, improve the slippery feeling during washing, can remove sebum and oil-based stains by solvent action, and have other benefits such as reducing the amount of water-insoluble polymers used. It's also effective. These solid oils may be solid at room temperature and can be used as raw materials for cosmetics.
Examples include ceresin wax, beeswax, spermaceti wax, carnauba wax, candelilla wax, paraffin wax, microblisterine wax, stearic acid, behenyl alcohol, and the like. Available for selection.

The coarsely pulverized product of the aggregate in the present invention is mainly composed of the above-mentioned components; the composition of these components; 501'1
9%, 10~ as a resin emulsion of water-insoluble polymer
It is in the range of 50% by weight, and further in the range of 10 to 50% by weight of solid oil. This range C is blended by changing the composition ratio as necessary.

In the present invention, the coarsely pulverized aggregates are, for example, short-t
When adding A-fibers, hydrophilic powder, and a solid oil agent, the previously melted 17 mixture is stirred and mixed, and the water-insoluble polymer solution is added to this while stirring, cooled, and dried. It can be easily obtained by a manufacturing method such as forming an aggregate and then coarsely pulverizing it with a pulverizer.

The skin care cosmetic of the present invention is obtained by dispersing the coarsely pulverized product of the above-mentioned aggregates in an aqueous base. It is easy to use. In this case, it is sufficient that the blending ratio of the coarsely ground aggregates is in the range of 5 to 70 percent, and the remainder is an aqueous phase consisting of water and other components.

In addition, the aqueous base and L7 in the present invention are water-based or O7
In addition, in the present invention, in addition to the essential ingredients listed in Section 111, raw materials usually added to cosmetics, such as inorganic pigments and organic powder components other than those mentioned above, coloring agents, Liquid oils, surfactants, fragrances, preservatives, humectants, beauty ingredients, and the like may be appropriately added to the composition as long as they do not interfere with the effects of the present invention.
