Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention mainly relates to basic cosmetics such as creams, emulsions, gels, packs, and lotions; skin cleansers such as body soaps and facial cleansers; shampoos, rinses,
It can be blended with various cosmetics such as hair cosmetics such as hair tonics and hair restorers; oral cosmetics such as mouthwashes and toothpastes; bath cosmetics such as bath salts and bubble baths. In particular, depending on the type of cosmetics, it can be used safely for people with allergic skin diseases, and it can be expected to suppress inflammation such as itching and bulkiness of the skin. The present invention relates to a cosmetic composition.

[0002]

2. Description of the Related Art In recent years, as cosmetics have become more and more natural in consumers, natural cosmetic raw materials that are less likely to cause side effects on the human body have attracted attention. Coral powder, which has been conventionally used also in foods, is one of them, and is known to be blended in various cosmetics. For example, skin agents containing calcium carbonate obtained from biological fossils including coral fossils (JP-A-7-196434), bath salts containing coral fossil or coral sand powder (JP-A-6-256161) Gazette) has been proposed. When coral powder is mixed with a gel-like product thickened with an organic polymer, depending on the type of organic polymer, the viscosity decreases due to the effect of inorganic ions eluted from the coral powder, and the coral powder settles. There is a problem that the commercial value is reduced. On the other hand, colloidal hydrated silicates are widely used in paints, pharmaceuticals, cosmetics, etc. by utilizing their gelling properties and swelling properties.
In the cosmetics field, it is mainly used as a thickener, and can provide a product with little stickiness, excellent spreadability, and no stringiness. Recently, it has been proposed that coral powder and colloidal hydrated silicate have an effect on allergic dermatitis such as atopic dermatitis and also have an effect on skin itchiness and dryness. In addition, it has been proposed that antibacterial action and anti-inflammatory action can be expected.

[0003]

Accordingly, coral powder and colloidal hydrated silicic acid have been proposed as cosmetics which are expected to improve itching, swelling of the skin, allergic dermatitis, etc., antibacterial action and anti-inflammatory action. Cosmetics containing salt are conceivable. In addition, by combining these, the effect of suppressing the sedimentation phenomenon of coral powder in the product can be expected due to the action of the colloidal hydrous silicate which also acts as a thickener.
However, cosmetics combining these are not commercially available,
In the case of actual experiments, contrary to expectations, the viscosity was remarkably reduced, the color tone was poor, and there was a problem with the product stability.Therefore, it was effective in improving the original skin itching, swelling and allergic dermatitis. Was not sufficiently obtained. Therefore,
An object of the present invention is to provide a cosmetic composition having excellent product stability, which is safe even for a person having atopic dermatosis, can effectively control rough skin, bulky skin, itching, etc., and can be used for various cosmetics. To provide things. Another object of the present invention is a cosmetic that contains both coral powder and colloidal hydrated silicate, has excellent product stability, and can be used in various cosmetics that can effectively bring out the action caused by these components. To provide a feed composition.

[0004]

Means for Solving the Problems The present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, have found that in cosmetics comprising a combination of coral powder and a colloidal hydrous silicate, the viscosity is lowered and the color tone is deteriorated. The cause of this was found to be a preservative to be blended. Furthermore, benzoate is effective as a material that suppresses the decrease in viscosity and the deterioration of color tone. By blending this benzoate, the decrease in viscosity and deterioration of color tone are suppressed even when other preservatives are blended. The present inventors have found that the desired effects on itching and skin bulkiness can be sufficiently obtained, and completed the present invention. That is, according to the present invention, there is provided a cosmetic composition comprising coral powder, a colloidal hydrated silicate, a benzoate, and water.
