Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a skin care composition such as a solid soap containing soap as a main component, a liquid body scrub, and a semi-liquid moist mask.

[0002]

BACKGROUND OF THE INVENTION Various skin care compositions have been proposed in the past, and by incorporating natural plant ingredients such as aloe extract and perilla extract, Some are intended to exert a moisturizing or anti-inflammatory effect on the skin. However, among natural materials, the use of coral as a component of a skin care composition has not been considered in the past.

The inventor of the present invention discovered that coral powder has an advantageous effect on human skin, and arrived at the present invention.

Therefore, the present invention has as its technical problem the provision of a skin care composition containing coral powder to assist in the treatment of atopic diseases and the like.

[0005]

In order to solve the above-mentioned problems, the present invention provides 0.5 to 30% by weight of coral powder,
0.1 to 50% by weight of surfactant and 15 to 90% by weight
To provide a skin care composition containing at least 0.1 to 30% by weight of sodium alginate and 1 to 20% by weight of glycols.

[0006] In the present invention, the reason why the coral powder exerts a good effect (for example, atopic suppression effect) on human skin has not been clarified yet, but the following possibility Can be considered.

That is, the main component of coral powder is calcium carbonate, which additionally contains iron and magnesium. Therefore, when the skin care composition according to the present invention is used, the skin which tends to be weakly acidic is neutrally conditioned to be protected, thereby exhibiting a preferable effect such as an atopic suppressing effect. Also, supplementing the minerals that tend to be in short supply is considered to partially contribute to the protection of sensitive skin.

The coral powder is porous and adsorbs dirt components adhering to the skin, and the finely-divided coral powder exerts the scrubbing action (in the range not damaging the skin) necessary for dirt removal. There is also an additional effect of enhancing the cleaning effect.

[0009]
