Problems solved by technology

Although the solid cosmetic described in the above-mentioned Patent Document 2 has a moisturizing feeling derived from an aqueous component, it still needs to be improved in terms of usability and durability.
That is, in order to use up the cosmetic material to the maximum, it is necessary to be able to stably maintain the durability of the three-dimensional shape to withstand continuous friction with the skin, and to prevent it from falling out of the container due to cracks or the like during use, but , only by adding a curing agent that solidifies water to cosmetics containing water to harden the cosmetics, it is difficult to make the cosmetics adhere to the skin, and the feeling of use will be spoiled

Embodiment 1～24 and comparative example 1～10

[0140] The oil-in-water type solid cosmetics (blush) of the composition (mass %) shown in Tables 1-4 were prepared according to the following manufacturing method, and the said evaluation was performed. The results are shown together in Tables 1-4.

[0142] First, the water phase component is dispersed in purified water, and the above-mentioned dispersion liquid is heated to 90° C. or higher to dissolve, and the water phase portion is obtained. Next, the oil phase part in which the oil phase component was uniformly mixed was added to the water phase part, it stirred sufficiently, and emulsification was performed. The obtained solution is filled in a designated mold at 60°C or higher, and allowed to cool, thereby obtaining a figure 1 An oil-in-water type solid cosmetic of the same shape as the product shown. Then, the obtained solid cosmetic was moved into a designated container where the protrusions of the oil-in-water solid cosmetic could be exposed, and this was...

Abstract

The present invention provides an oil-in-water solid cosmetic containing a powder component, a gelling agent, a water-soluble thickener, water, and an oil agent, the powder component containing 3-30% by mass of a plate-shaped powder having an average particle diameter of 10-200 [mu]m and an aspect ratio of 40-200 based on the total amount of the cosmetic, and the gelling agent containing agar and/or gellan gum.

Description

technical field [0001] The present invention relates to oil-in-water cosmetics and cosmetics. Background technique [0002] Make-up cosmetics such as blush, eye shadow, foundation, and lipstick are used in the form of storing the cosmetics filled in a metal pan in a small container. Cosmetics in such a form are generally applied to the skin using an applicator. [0003] In recent years, in order to improve visual value such as good aesthetics and convenience, studies have been made on the shape of cosmetic containers and cosmetic main bodies. For example, JP-A-2015-231968 (Patent Document 1) and JP-A-2006-182736 (Patent Document 2) propose products in which cosmetics formed in a three-dimensional structure protrude from the container. Cosmetics having such a form can be directly applied to the skin without using an applicator. [0004] When cosmetics are applied in direct contact with the skin, they are required to have usability such as a comfortable feeling on the skin ...
