Description

Solid make-up cosmetic composition {Solid make-up cosmetic composition}

The present invention relates to a solid makeup cosmetic composition.

In general, in order to prepare a makeup cosmetic composition in a solid state, an oil thickener is used to harden the formulation of the contents. However, when a large amount of such an oil thickener is used, the pay-off is not good because both the outside and the inside of the cosmetic are hard like a general chestnut type cosmetic composition. However, when the content of such an oil thickener is small, it is prepared in a liquid and solid intermediate form, which is a form that is difficult to be called a solid form, and there is a problem in that it is difficult to take the contents using a puff or the like.

Accordingly, an attempt has been made to manufacture a solid cosmetic so that the surface forms a certain degree of hardness by using an oil thickener that gives a feeling of elasticity, but the hardness inside the cosmetic is too low and the contents collapse. There was a problem that was difficult to take.
