Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition, and an object thereof is to provide a cosmetic composition having a high stain and dullness removing effect.

[0002]

2. Description of the Related Art Destruction of the ozone layer, which is one of the deterioration of the living environment due to the priority of industry, has led to an increase in the irradiation of ultraviolet rays, which has an unexpected effect on human skin as well as global warming. I understand. In other words, it is the increase in female skin's stains and dullness caused by ultraviolet rays. At the same time, in Japan, post-war social life has become Westernized, and the dietary habits have shifted from traditional vegetable-based diets to meat-based diets. It is said that is easy to come out.

Under these circumstances, UV-blocking agents by various drugs in recent years, tyrosinase production inhibitors that are thought to promote pigmentation in the skin, placenta of animal biological components which are required to have a beautiful skin effect, or conventionally. The use of crude drugs such as senkyu, psyche, bowhu, sohaku, and licorice, which are used in traditional Chinese medicine, is used. However, those using drugs often have side effects at the site of use of the skin, and the price is expensive as a cosmetic, while other products have the problem that the effect cannot be expected.

[0004]

[Problems to be Solved by the Invention] According to a cosmetics report issued by the Japan Cosmetic Industry Association, 80% of people reported feeling "dull skin" in a Japanese women's attitude survey on "dull skin". However, this can be said to show how great the impact of the changes in the living environment described above is on contemporary Japanese women. Under these circumstances, the role of cosmetics is not limited to simply moisturizing and preventing the skin from being dried, and there is a demand for those that specifically or positively remove or prevent stains and dullness.

[0005]

[Means for Solving the Problems] The present invention has been studied eagerly to provide a cosmetic for preventing and removing stains / dullness which can be suitably used for solving the above-mentioned problems. The inventors of the present invention have found that a mixture of magnesium chloride, potassium chloride, sodium chloride and magnesium sulphate can effectively prevent or remove stains and dullness.

[0006]

The present invention is based on magnesium chloride 15-19.
g, potassium chloride 2 to 4 g, sodium chloride 2 to 6 g,
At least 0.01% of a mixture (hereinafter referred to as "the mixture of the present invention") having a limited weight mixing ratio within the range of 6 to 9 g of magnesium sulfate in 100 g of cosmetics.
It is a cosmetic composition containing the above components.

The dosage form of cosmetics using the mixture of the present invention may be any of lotion, emulsion, cream, shampoo, treatment, soap and the like. In this case, any cosmetic base material known in the art can be used.

Magnesium chloride constituting the mixture of the present invention is a colorless to white crystalline substance represented by the chemical molecular formula described separately.

【Example】

 (Example 1. Transparent soap) A transparent stone piece having the following composition was produced by a conventional method. Soap content 60.0 (% by weight) Sugar 12.0 Glycerin 10.5 Moisture 15.5 Mixture of the present invention 0.5 (breakdown) Magnesium chloride 0.3 Potassium chloride 0.04 Sodium chloride 0.04 Magnesium sulfate 0. 12 Perfume 1.5

[0013]

(Test on Use of Transparent Soap of Example 1) Ten females each having spots and dullness on the skin, a total of 20 females, used the soap once a day at the time of bathing, and the effect after one month investigated. Table 1 shows the test results. The evaluation criteria were divided into the following 5 levels according to the degree of symptoms, and the degree of improvement was judged based on the degree of increase in the evaluation level before and after use, and the results are shown in Table 2.

(Evaluation Criteria) Stain 5. A clear stain is visible on the face and the color is dark. 4. You can see clear stains on your face, but they are not noticeable with makeup. 3. There are spots on the face, but the outline is not so clear. 2. I have stains on my face, but I don't know unless I look closely. 1. I can hardly see the stains on my face.

[Table 3]

(Effect of the Invention) As described in detail above, the present invention provides a cosmetic composition containing a mixture of magnesium chloride, potassium chloride, sodium chloride and magnesium sulfate at a specific blending ratio. As can be seen from the test results (Table 1) and the improvement rate (Table 2), the stain / dullness removing cosmetic composition according to the present invention is
It has an excellent effect on removing spots and dullness of women's skin.
