[0145] Preparation method of powder solid cosmetic

[0146] The powdery solid cosmetics of the present invention can be prepared by mixing various constituents including the amide mixture described above, the powder component and the oily component by a conventional method, for example, by a method of mixing under dry conditions (dry manufacturing method) , Dispersed in a wet system, slurried, and then dried to prepare any one of the methods (wet method).

[0147] dry method

[0148] When preparing the powdery solid cosmetic of the present invention by a dry method, it is particularly preferable to mix the above-mentioned amide mixture with the powder component and the oily component using a mixer of a specific configuration with opposed rotors described below. By using this mixer with opposing rotor blades, it is possible to uniformly coat the surface of the oil-based component without agglomeration of the powder component, and the obtained powder solid cosmetics have a ...

Embodiment

[0202] Hereinafter, examples of the present invention will be given and described concretely, but the present invention is not limited thereto. In addition, the quantity in the following prescription shows by mass %.

[0203]

[0204] (A) Evaluation of Makeup Persistence (makeup faded and oily)

[0205] The formulations shown in the table below prepared foundation foundations through the above-mentioned slurry preparation steps and powder solid cosmetic preparation steps, and the following methods were used to conduct subject tests for the makeup durability. The obtained foundation was applied to the skin by 10 test subjects specialized in cosmetics. Then, 3 hours later, 3 professional evaluators performed a 10-level evaluation based on the following evaluation criteria for each evaluation item of "Evaluation of makeup change" and "Evaluation of oily shine" (makeup durability is very poor: 0 points to makeup durability Very good performance: 10 points), and further judged ...

preparation example 7-1

[0274] Preparation Example 7-1: After mixing the various ingredients in the prescription with a Henschel mixer (manufactured by Mitsui Miike Chemical Industry Co., Ltd.) for a certain period of time, use figure 1 Rotary wing opposing type mixing device (cyclone grinder: Flowtec Corporation, the first rotor and the second rotor are used to rotate in opposite directions to each other) to mix twice, and dry press molding in a resin medium vessel .

Abstract

Provided is a powdered solid cosmetic that lasts well and is excellent at preventing makeup running and oily shininess. Said powdered solid cosmetic is characterized by containing: a powder component; an oil-based component that serves as a binder; and a mixture of hexamethylenediamine and bis(aminomethyl)cyclohexane which has been amidated in hydrogenated castor oil fatty acid, resulting in an amide mixture. The amide mixture preferably constitutes 1.0-15% by mass of the cosmetic. As a powder component, spherical poly(metha)acrylate particles are preferably included, constituting 1-20% by mass of the cosmetic. An organically-denatured clay mineral is preferably included such that the mass thereof and the mass of the amide mixture total 1.0-15% of the total mass of the cosmetic. As a powder component, a powder treated by a fluorine compound is preferably included, constituting 5-97% by mass of the cosmetic.

Description

[0001] related application [0002] This application claims the priority of Japanese Patent Application No. 2009-99938 filed on Apr. 16, 2009, the contents of which are incorporated herein. technical field [0003] The present invention relates to powder solid cosmetics and a preparation method thereof, in particular to the improvement of makeup durability for powdery solid cosmetics with faded makeup and oily shine. Background technique [0004] Powdered solid cosmetics such as powder foundations have been conventionally prepared as follows. The powder ingredients are mixed using a stirring mixer such as a Henschel mixer (registered trademark), a Nauta mixer (registered trademark), a ribbon mixer, and a kneader. Mix it with an oily component as a binder, pulverize the mixture with a pulverizer such as a pulverizer, fill it into a medium-sized dish made of metal or resin, or perform dry pressure molding, thereby Preparation of powder solid cosmetics. These conventional met...
