DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inorganic salt-containing cosmetic for containing a polyhydric alcohol, an inorganic salt and a glycerin ester-based nonionic surfactant.

[0002]

2. Description of the Related Art Water-soluble inorganic salts such as sodium chloride,
In particular, dried seawater has an effect of promoting blood circulation and removing waste products, and is used by directly applying it to the skin or applying an aqueous solution.

[0003] In recent years, there have been many reports on the treatment of atopic dermatitis. Among them, there have been many reports that inorganic salts such as seawater and hot spring water are effective for the treatment, and pharmacologically reviewed. I have.

The use of inorganic salts in a granular form has a so-called scrub effect of promoting blood circulation and removing wastes by rubbing, but most of them dissolve when sweating or washing away during use. It does not cause skin trouble by remaining after use such as plant seeds such as apricot shell particles and resin such as polyacrylic acid like scrub cosmetics.

[0005] Polyhydric alcohols have the property of solubilizing oil and water, have the effect of removing excess oil and water present on the skin to remove aging keratin that has lost water and oil, and the property of easily retaining water. Has moisturizing effect. In particular, polyhydric alcohols such as glycerin have the property of generating heat when absorbed,
A warm feeling can be imparted using this.

[0006] Glycerin ester nonionic surfactants are widely used for solubilization, emulsification, and the like, and are widely used in foods because of their high safety.
These surfactants have various properties depending on the difference in structure, and have effects such as cleaning, moisturizing, and supplementing oil.

[0007] Most of atopic dermatitis is due to the fact that aging keratin contains oil and water and is excessively stacked to disturb the metabolic rhythm, but inorganic salts and polyhydric alcohols cause aging keratin. It has the property of removing certain oils and moisture, and aging keratin is easily peeled off from the skin, and aging keratin and waste can be removed by rubbing with granular inorganic salts. This has the effect of revitalizing the skin and adjusting the metabolic rhythm. The use of a combination of a polyhydric alcohol and an inorganic salt is excellent as a means for activating the skin.

[0008]

The above-mentioned inorganic salts having high water solubility such as sodium chloride are blended with conventional water-containing cosmetics while maintaining their granularity because of their high water solubility. In addition, polyhydric alcohols are liquid and inconvenient to use as cosmetics.

[0009]

According to the present invention, a polyhydric alcohol is mixed with a glycerin ester-based nonionic surfactant and heated to increase the crystallinity, and a water-soluble inorganic salt such as sodium chloride is dispersed therein. By doing so, sedimentation of the granules can be prevented while maintaining the granularity, and the above problem can be solved.

The polyhydric alcohol used in the present invention includes glycerin, diglycerin, polyglycerin,
3-butylene glycol, ethylene glycol, diethylene glycol, polyethylene glycol, propylene glycol, dipropylene glycol, polypropylene glycol, and the like.
Mix and use two or more products.

The inorganic salt used in the present invention is a salt of hydrochloric acid, sulfuric acid, carbonic acid, bicarbonate or the like such as sodium, potassium, magnesium and calcium, and one or more of them are used in combination. Dried seawater is also used as the mixed inorganic salt. It is desirable to use a water-soluble inorganic salt as a main component so that it does not remain on the skin and cause trouble.

Next, glycerin ester-based nonionic surfactants used in the present invention include glycerin fatty acid ester, glycerin acetate fatty acid ester, glycerin lactic acid fatty acid ester, glycerin citrate fatty acid ester,
Glycerin succinic acid fatty acid ester, glycerin diacetyltartaric acid fatty acid ester, glycerin acetate,
Examples thereof include polyglycerin fatty acid esters and polyglycerin condensed ricinoleic acid esters, and one or more of them are used in combination. In order to stably disperse the inorganic salt, it is desirable to use a surfactant that easily forms a crystal structure. In addition, if a cleaning property or a moisturizing property is imparted, a surfactant suitable for the property is selected.

In the present invention, the amount of the polyhydric alcohol is
The maximum blended amount is 95%, calculated from the blended amount of the inorganic salt. When the amount is less than 20%, the amount of the inorganic salt increases, so that the product becomes hard, and it is difficult to maintain the paste state. Even if water is mixed, water is 15%
If it enters above, it becomes soft and cannot maintain the paste state. Therefore, the blending amount of the polyhydric alcohol is 20% to 9%.
5% is the use range.

Next, when the amount of the inorganic salt is less than 1%,
The number of grains is reduced, and the effect of the present invention cannot be expected. On the other hand, if it exceeds 80%, the amount of the inorganic salt is too large and the paste becomes hard and cannot keep a paste state. Therefore, the content is 5%
-70% is preferable, and the amount is determined according to the purpose of use.

[0015] Since the dosage form of the cosmetic of the present invention depends on the crystallinity of the glycerin ester-based nonionic surfactant, the amount of the inorganic salt added can be freely adjusted.

Further, the crystallinity differs depending on the type of the glycerin ester-based nonionic surfactant, and by adjusting them, it is possible to produce a cosmetic having a wide range of hardness.

In order to maintain the particle shape of the inorganic salt, it is preferable that the water content is as small as possible. However, if it is desired to suppress the dehydrating action and the heating action of the polyhydric alcohol, the water content should be within 15% of the total. It is possible to mix the inorganic salt while maintaining the above condition, and it is effective when water is contained to smooth the surface of the grains and reduce the physical irritation.

Other additives other than those described above include hydrocarbons such as squalane, ester oils such as jojoba oil, oils such as olive oil, fatty acids such as stearic acid, higher alcohols such as cetanol, and silicone oils as skin fatliquors. And, as a skin protective component, proteins such as milk protein and its decomposed products, mucopolysaccharides such as hyaluronic acid, sugars and sugar alcohols such as maltose, extracts of animals and plants, etc. to such an extent that stability is not affected. If present, it can be blended. Chili peppers, which are especially used as spices
Addition of fine powders or extracts such as ginger, peppermint, citrus peel, cinnamon, clove, fennel, garlic, pepper, sansho, perilla, apricot, almond, etc., promotes blood circulation and maintains the heat effect and sweating power. Therefore, the above substances are used alone or as a mixture. 0.01% of the substance added
~ 5%.

When the amount is less than 0.01%, the effect is small, and when it is 5% or more, the stimulation becomes too strong. Addition of a small amount of an oil agent or the like is also effective in adjusting the crystallinity.

[0020]

EXAMPLE 1 To 97 parts of glycerin, 3 parts of a plurality of glycerin fatty acid esters listed in the Official Standards for Food Additives (Sixth Edition) were added to make 100 parts in total, and the mixture was heated and dissolved to prepare a base.

A base was added to an arbitrary amount of 5, 10, 30, 50, or 70 parts of the seawater dried product listed in 1993, which is a compounding component specification for each cosmetic type, and the whole was uniformly mixed to make 100 parts.

It is hardly affected by the amount of dried seawater,
An almost uniform paste-like cosmetic was obtained. All the cosmetics did not change in properties for a long time (6 months) even at a high temperature of 40 ° C., and were stable for a long time (6 months) even at a low temperature of 5 ° C., and the properties of the paste did not change. In addition, since a high-viscosity material such as an organic polymer was not used, it was less sticky, had good elongation to the skin, and was excellent in thermal sweating effect. They were almost never applied to the body and run off.

When the seawater dried product is mixed with 5, 10 or 30 parts, it is used as a massage for a part where the stimulus caused by rubbing is to be avoided because of a small grain feel, or as a pack which is applied and left for a while. The skin had a moist feel while smoothing the skin and removing dirt.

A mixture of 50 and 70 parts of dried seawater has a high physical stimulus when used for massage, so it is excellent in a heat effect and an effect of removing waste products, and has a high sweating property and an effect of conditioning dry skin. Was.

All of them have been applied for a while, the feeling of warmth has increased, and the dried seawater gradually dissolved due to sweat, and almost no particles remained when washed out. The eluted seawater dried matter promoted blood circulation, and there was a sustained warm feeling even after use.

Example 2 20 parts of glycerin were previously added to 1,3
-Add 62 parts of butylene glycol, 15 parts of water, and 3 parts of a plurality of glycerin fatty acid esters listed in the Official Supplement of Food Additives (Sixth Edition) to make the whole 100 parts, and heat and dissolve to prepare a base.

A base was added to an arbitrary amount of 5, 10, 30, 50, or 70 parts of a seawater dried product listed in 1993, which is a compounding component specification for each cosmetic variety, and the whole was uniformly mixed to make 100 parts.

In each case, the surface of the dried seawater particles was smooth and almost unaffected by the amount of the dried seawater, and almost uniform paste-like cosmetics were obtained. All cosmetics are 4
No change in properties for a long time (6 months) even at a high temperature of 0 ° C, 5 ° C
The paste was stable for a long period (6 months) even at a low temperature, and the paste-like properties did not change. In addition, since a high-viscosity material such as an organic polymer was not used, stickiness was small and the elongation to the skin was good. They were almost never applied to the body and run off.

When the seawater dried product is blended with 5, 10 or 30 parts, since the feeling of the grains is small, it is used as a massage to avoid the irritation caused by rubbing or as a pack which is applied and left for a while. The texture of the skin was adjusted and the dirt was removed, but the touch was moist.

When the seawater dried product was mixed with 50 or 70 parts, the physical stimulation was high when used for massage, so that the effect of removing wastes was excellent and the effect of preparing rough skin was high.
