Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for producing multicolored oil-based cosmetics such as lipsticks, blushers, eye shadows, lip balms, and the like.

[Conventional technology]

Conventionally, the method for producing multicolored oil-based cosmetics was disclosed in Japanese Patent Application Laid-open No. 1986-
There is one shown in Japanese Patent No. 225108. In this method, the basic raw materials of each single color are blended and melted in a pair of blending tanks, and are directly introduced into a rod-shaped cosmetic mold that is rotatably installed below the conduits connected to the blending tanks. The aim is to produce multicolored bar-shaped cosmetics by filling the product.

[Problem to be solved by the invention]

By the way, the above-mentioned conventional technology has a drawback in that only a spirally patterned bar-shaped cosmetic can be produced because a rotating mold for molding a cosmetic bar is filled with a plurality of basic raw materials of different colors. For this reason, even if the combination of colors is changed, the pattern formed is almost the same, so it has not been possible to provide a multicolored oil-based cosmetic that is innovative and satisfies the tastes of consumers.

The present invention was made in view of the above-mentioned shortcomings of the prior art, and is a multi-colored oil-based cosmetic that can easily produce a multi-colored oil-based cosmetic in which multiple ingredients such as colors are integrally molded independently without mixing them. The object of the present invention is to provide a method for producing oil-based cosmetics.

[Means to solve the problem]

In order to solve the above-mentioned problems, the means adopted by the present invention is to heat a multi-colored oil-based cosmetic base containing an oil-based raw material and at least one of a powder or a dye as a coloring agent to change the color. A first step of producing a plurality of different paste-like products, and a molding nozzle having a plurality of paste-like inlets and a single discharge port for each color, forming a plurality of paste-like products of different colors. a second step of collecting the objects and extrusion molding them into a single rod; a third step of cooling and solidifying the rod to form a solid rod-shaped cosmetic; and a third step of molding the solid rod-shaped cosmetic. and a fourth step of cutting it into a predetermined shape and molding it into a multicolored oil-based cosmetic.

Furthermore, the oil-based cosmetic base may be composed of 30 to 100% by weight of oily raw materials and 70% by weight or less of powder.
Furthermore, it may be composed of an oily raw material and a dye.

[Specific structure of the invention]

The oil-based cosmetic base used in the present invention includes, for example, liquid oil such as liquid paraffin, synthetic ester oil, and olive oil, oil-based raw materials such as solid paraffin, wood wax, beeswax, and carnauba wax, and dyes such as organic pigments or The composition contains a small amount of either one of the powders. The blending ratio of the oily raw materials contained in the oily cosmetic base is preferably 30 to 100% by weight. .5
Add % dye by weight. Furthermore, when producing make-up cosmetics, a powder consisting of 70% by weight or less of an inorganic pigment is added to the oily raw materials, and when producing solid perfumes, fragrances are added. Powders include extender pigments, colored pigments, metal soaps, crowbar materials, etc.

In the present invention, the oil-based cosmetic base is heated and melted by a heating means to form a paste-like product. The heating melting temperature in this case is 70 to 100'C, which is higher than the melting point.

Now, in the first step of the method of the present invention, the above-mentioned oily cosmetic base is heated and melted to produce a paste-like product for each color. Next, in the second step, a molding nozzle is used to collect the paste-like materials of each color so that they do not mix with each other,
Extrusion molded into a single rod shape. Here, the molding nozzle has two or more paste-like injection ports through which paste-like materials are injected under pressure for each color, and the injected paste-like materials of each color are discharged in a collected state. The molding nozzle is configured so as not to mix the paste-like materials of each color with each other.

In the third step, the rod formed in the second step is cooled and solidified to form a solid rod-shaped cosmetic having a predetermined hardness.

The degree of hardness is determined so that the solid rod-shaped cosmetic does not lose its shape and can be easily cut in the fourth step described later with a good finish. There are methods such as water cooling using a water jacket and air cooling using cooling air.

In the fourth and final step, the solid rod-shaped cosmetic material that has been cooled and thinned as described above is cut into small pieces of multicolored oil-based cosmetic material having a desired shape and molded. This cutting method includes a method of cutting the solid rod-shaped cosmetic along the axis, a method of cutting perpendicular to the axis, a method of cutting diagonally to the axis,
Furthermore, an appropriate cutting method can be used, such as a method of cutting so that the cut surface becomes wavy.

[Effects of the Invention] According to the above-described method of the present invention, paste-like materials of each color are aggregated without mixing with each other, extruded into a single rod shape, cooled and solidified, and then cut. With this structure, it is possible to produce a multicolored oil-based cosmetic with a beautiful appearance in which the boundaries between each color are clearly expressed. In addition, it is possible to produce a multi-colored oil-based cosmetic in a single extrusion molding process, in which not only the color but also multiple types of base components, such as a portion containing many oil-based raw materials and a portion containing many pigments, can be used selectively. Can be done. Furthermore, by devising the cutting direction during the cutting process,
A desired pattern can be obtained.
