Abstract

PURPOSE:To simplify various production processes and obtain a solid powdery cosmetic, by using a fluorohydrocarbon as a blending solvent, blending the fluorohydrocarbon with a powdery cosmetic base while stirring, forming the resultant blend into a granular material, etc., filling the blend in a cosmetic container and volatilizing the fluorohydrocarbon after filling. CONSTITUTION:A powder cosmetic base containing much pearling agent powder, e.g. titanium-mica based agent, etc., is blended with a fluorohydrocarbon, e.g. Flon-Showa FS-11(R), etc., having <=50 deg.C boiling point while stirring by a suitable method to give a granular or liquid form. The resultant material is then filled in a cosmetic container and the fluorohydrocarbon is volatilized after filling. The powder is readily pressurized while applying a screen, e.g. cloth or paper, to the powder surface to afford the aimed solid powdery cosmetic. EFFECT:The fluorohydrocarbon has good affinity for the cosmetic base and stirring and blending are facilitated. Since equipment required for the stirring may be simple and the fluorohydrocarbon is readily volatilized, the pressurizing operation after the volatilization may be simple.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is a method for producing solid powder cosmetics that can simplify various production steps by using a fluorinated hydrocarbon as a mixing solvent.

(Prior art) In the wet method, which is used as one of the conventional methods for manufacturing solid powder cosmetics, a predetermined amount of the powder cosmetic base is put into a mixer called a kneader, and then water is added. Alternatively, a powdered cosmetic base is mixed and dispersed while stirring in a kneader by adding a solvent such as ethyl alcohol. ■Next, the powdered cosmetic base is dried at a constant temperature and then crushed.■This crushed powdered cosmetic base is transferred to a molding machine called Allen Core Light.■Allen Core Light The powdered cosmetic base is filled into a cosmetic container from the tip of the ompper, and then compression molded.

Such conventional technology has the problem that not only is the manufacturing process complicated, but powdered cosmetics containing a large amount of titanium-mica pearl agent powder are difficult to solidify even when compression molded. Was.

In recent years, in addition to being able to omit the steps ① and ② above, it also contains a large amount of titanium-mica pearl agent powder45]
A filling method that can fill and solidify non-cosmetic materials was published in 1977.
These methods are disclosed in Japanese Patent Laid-Open No. 60004, Japanese Patent Application Laid-Open No. 127305/1980, etc., but each method has the problem that the equipment used for filling and molding is expensive and has a complicated mechanism.

The present invention aims to simplify these steps and equipment, and to improve titanium-
The aim is to solidify powdered cosmetics containing a large amount of mica-based pearlescent agent 45) powder, and the above-mentioned problems are solved by using a fluorinated hydrocarbon as a mixing solvent.

(Means for Solving the Problems) That is, the present invention provides a method for filling a powder cosmetic into a container and molding it to obtain a solid powder cosmetic. Stir hydrogenated hydrocarbons using an appropriate method 1! This is a method for producing a solid powder cosmetic, which is characterized in that the powder is mixed and made into granules or fluid, and then filled into a cosmetic container, and after filling, the fluorocarbon and arsenic are volatilized.

The fluorinated hydrocarbon used in the present invention has a temperature of 911 points at 50°C.
The following fluorinated hydrocarbons, specifically Fronshower F
S-114 (registered trademark), Fronshowa I'5-11
(registered trademark), Fronshowa I'5-12 (,
(registered trademark). The amount of fluorinated hydrocarbon blended is 10 to 10% in weight concentration at the time of mixing.
If the amount of fluorinated hydrocarbon is small, the powder cosmetic will be granular, and if the amount of fluorinated hydrocarbon is large, it will be fluid.

The powdered cosmetic mixed with the fluorinated hydrocarbon is stirred by hand, by simple stirring using a kneader, or by omitting these operations in a hopper using a screw, and then filled into a cosmetic container from the tip of the hopper. Recently, solid powder cosmetics can be obtained by allowing the fluorinated hydrocarbon to volatilize by leaving it for a certain period of time, and then applying pressure to the surface of the powder cosmetics while applying a screen of cloth or paper.

However, fluorinated hydrocarbons are used as powder cosmetic bases and
Since it has good affinity with the above components, there is no need to spend time on mixing and stirring, and the mixing step (2) shown in the prior art section is almost unnecessary. In addition, since fluorinated hydrocarbons are easily volatilized, they have the advantage of eliminating the need for the drying step (1) and the crushing step (5).

The solid powder cosmetics in the present invention are ordinary foundations, white powders, eye shadows, and blushers, and their powder components include titanium-mica pearl agents, mica powders, titanium oxide, talc, zinc oxide, etc. Type 1 or 2
Contains more than seeds, liquid paraffin, lanolin, if necessary.
It contains oils such as squalene, humectants such as glycerin and 1.3 propylene glycol, surfactants, pigments, and ultraviolet absorbers.

(Function) Since fluorinated hydrocarbons have good affinity with powder cosmetic bases, they penetrate well between powders while well dissolving oil, surfactants, pigments, etc. in the base.

After permeation, the powders are completely mixed with each other, and even after the fluorinated hydrocarbon is scattered, the powder cosmetic bases are in close contact with each other, so that the pressure required for solidification is extremely small.

(Example) Preferred embodiments of the invention will be described below.

Example 1 0.16 g of Freon Showa FS-11 was added to 1 g of foundation having the formulation shown in Table 1, and the mixture was stirred well for 2 to 3 minutes in a Ni-Goo.

This mixture was transferred to an Allen core light popper, and distributed from the hopper into compact medium trays in log increments. 20
Leave it at room temperature for ~30 seconds and rinse it with Fronshowa Its-11
After volatilizing, a solid foundation was molded by applying a pressure of 5 kg/cryl with a press head while covering the surface of the foundation with a cloth.

Example 2 0.3 g of Fronshower r'S-12 was added to 1 g of the blush of the formulation shown in Table 2, and the mixture was washed manually for 5 minutes.
After mixing and stirring, the mixed product was transferred to an allene coreite hopper. Dispense 3g of blusher from the tip of the hopper into a medium dish, leave it at room temperature for 20 to 30 seconds, and apply a pressure of 5 kB7 cm with a press head while covering the blusher with paper to obtain a solid blusher. .

Example 3 0 per 1 g of eye shadow made of the formulation shown in Table 1
．． Fronsyowa FS-114 was blended in a proportion of 14 g and stirred in a powder inner to obtain granular Aisha IS-. After distributing this in Ig portions onto the inner tray, a solid eyeshadow was obtained by applying pressure with a press head while applying a cloth to the eyeshadow surface.

(Effects) As detailed above, by using fluorinated hydrocarbons in the manufacturing method of solid powder cosmetics, the powder cosmetics can be easily stirred and mixed, and can be mixed in a short time. , The equipment required for League 11 may be simple,
Depending on the type of powdered cosmetic, it can now be stirred sufficiently by hand.

Further, since fluorinated hydrocarbons are easily volatilized and have the effect of solidifying the powdered cosmetic after volatilization, less pressure is required for pressing, and a simple press molding machine is required.
