Description

The present invention is a solid powder cosmetic characterized in that a cosmetic base material prepared by mixing a powder and an oil agent is mixed with an aqueous solvent to form a slurry, and after filling the slurry into a container, the solvent is removed. The present invention relates to a method for producing a solid powder cosmetic that has a good feel on use and sufficient impact resistance by containing a specific powder.

There are two methods for manufacturing solid powder cosmetics: a dry molding method in which powder and oil are mixed and then compacted; and a volatile solvent is added to the cosmetic base material, which is a mixture of powder and oil, to form a slurry, which is then filled into containers. There is a wet molding method in which cosmetics are obtained by drying and removing volatile solvents. The wet molding method is known to have excellent sliding properties (smoothness) during use because the powder is easier to align compared to the dry molding method (Non-Patent Document 1). In the wet molding method, volatile oils such as volatile silicones and low-boiling hydrocarbons have traditionally been used as solvents, but these volatile oils are dangerous and difficult to manage, and there are also concerns about environmental protection. It is necessary to recover the removed volatile oil from the viewpoint of safety, and it is also necessary to take safety measures for workers from the viewpoint of safety. Against this background, a manufacturing method using an aqueous solvent is required. However, when using aqueous solvents, the resulting products have problems such as insufficient powder removal, insufficient smoothness during application, and poor impact resistance compared to when volatile oils are used. Ta.

In order to solve these problems, we have developed a method of blending a bondable powder, a specific composite powder, and a hydrocarbon oil (Patent Document 1), a hydrophobized powder, a polyhydric alcohol, a specific silicone gel composition, Method of blending a specific activator (Patent Document 2), Hydrophobized powder and polyhydric alcohol, Specific flexible organic resin powder, Method of blending a specific activator (Patent Document 3), Hydrophobized powder and A method of blending a polyhydric alcohol, a hydrating oil, and a specific active agent (Patent Document 4), and a method of blending a layered silicate mineral, a hydrophilic spherical powder, and a specific oil (Patent Document 5) are known. .
