Description

  Although the present invention is a powdery cosmetic, it has an excellent astringent effect (antiperspirant effect) at the time of use, a uniform coating film can be obtained with a refreshing feel, excellent makeup sustainability and storage The present invention relates to a water-containing powdery cosmetic material with extremely good stability.

Conventionally, powdery cosmetics are used in foundations, white powder, blusher, body powder, antiperspirant powder, and the like. Powdered cosmetics are known as powders whose main ingredient absorbs excess sebum, prevents makeup collapse, absorbs sweat, and obtains a deodorant effect, but has no volatile components The astringent action and the refreshing feeling were not obtained.
The astringent action is not only an antiperspirant effect that suppresses the secretion of sweat, but also an effect of tightening the skin and improving the longevity of makeup, and is an important factor in the effect of cosmetics. The substance having an astringent action such as alum is also used as a bath preparation, and also in powder cosmetics, a technique of blending pharmacopoeia alum, gum arabic, inert powder and zinc oxide (for example, Patent Document 1). And cosmetics containing aluminum potassium sulfate as an antiperspirant component have been developed (see, for example, Patent Document 2).
On the other hand, a powder cosmetic technology has been developed in which an aqueous component is coated with powder and the appearance is powdery, but liquefies by rubbing. (For example, see Patent Document 3 and Patent Document 4)

Japanese National Patent Publication No. 6-509081 JP 2010-77094 A JP-A-5-65212 JP 2001-131528 A

However, alum dissolves in water and exhibits acidity by hydrolyzing aluminum sulfate in a double salt, and exhibits an astringent effect on the skin and mucous membranes. Therefore, even if it is in powder form, its effect can be obtained if it is dissolved in water at the time of use like a bath preparation, but it is effective in powdered cosmetics that contain almost no moisture. I couldn't do it.
In addition, there is nothing that exhibits an excellent astringent action in the form of a powder, and many of them exhibit their effects when dissolved in water. It was difficult.
Therefore, it was considered that an alum can be contained in an aqueous gel and a water-containing powder cosmetic comprising a hydrophobic powder is coated, so that an excellent astringent action can be exhibited even in a powder cosmetic. It was found that it was difficult to form a powder when the aqueous gel was broken.
For this reason, even though it is in powder form, it has an excellent astringent effect (antiperspirant effect) at the time of use, and a uniform coating film is obtained with a refreshing feel, excellent makeup sustainability, and storage stability There has been a demand for providing very good powder cosmetics.

  In view of the above situation, as a result of intensive studies, the present inventor can prepare a stable aqueous gel by combining alum with a chelating agent in an aqueous gel and solve the above problems. The present invention has been completed. This is considered that the aluminum hydroxide produced by the hydrolysis of aluminum sulfate in alum precipitates and precipitates by heating, thereby inhibiting the gelling ability of the aqueous gelling agent. It has been found that when a chelating agent is contained, the hydration property of aluminum ions can be improved, so that the aqueous gel becomes stable without impairing the gelling ability and the above-mentioned problems can be solved.

That is, the present invention
