Description

The present invention relates to solid powder cosmetics.

Solid powder cosmetics are widely used for make-up cosmetics such as foundation, white powder, eye color, cheek color, and eyebrow, and basic cosmetics such as body powder and whitening powder because of their portability and ease of use. ing. Further, in recent years, techniques using fine metal oxide particles have been studied in order to improve the UV protection ability and to provide a finish with a transparent feeling without a white film (see, for example, Patent Document 1).

As a method for producing solid powder cosmetics, there is a dry molding method in which powder and oil are mixed and then press-molded, and a solvent is added to a cosmetic base material composed of powder and oil to form a slurry, which is then filled into a container. A wet molding method is well known in which a cosmetic is obtained by removing the solvent after drying. Since the solid powder cosmetic obtained by the wet molding method is filled in a fluid slurry state, it can be filled into containers of various shapes, and a highly aesthetic cosmetic can be obtained. On the other hand, the wet molding method sometimes poses a problem of filling moldability, and various studies have been made. For example, in order to improve filling moldability, techniques using film-forming polymers (see, for example, Patent Document 2) and techniques using spherical polyolefin resin powder and non-volatile oil (see, for example, Patent Document 3) are known. It is

However, when a solid powder cosmetic is produced using the technique of Patent Document 1 in order to obtain a cosmetic with excellent UV protection and transparency, a squeaky feeling due to the strength of the cohesive force of the fine particle metal oxide is produced. In addition, it was not possible to obtain a smooth molded product surface.

Moreover, when a solid powder cosmetic containing fine metal oxide particles is produced by a wet molding method, the removal efficiency of the solvent may be lowered due to the large surface area, and shrinkage of the molded product may occur. rice field. This is because even when the technique of Patent Document 1 is used, the squeaky feeling and shrinkage of the molded product due to the fine particle metal oxide cannot be suppressed, and furthermore, the polymer forms a film on the surface of the molded product, resulting in a satisfactory performance. In some cases, the smoothness of the molded product surface could not be obtained. Similarly, even when the technique of Patent Document 2 is used, the squeaky feeling and the shrinkage of the molded product due to the fine metal oxide cannot be suppressed, and the impact resistance is sometimes inferior.

Accordingly, the main object of the present invention is to provide a solid powder cosmetic which has excellent transparency, no squeaky feeling, excellent surface smoothness of the molded product, no shrinkage of the molded product and excellent impact resistance. and

In view of such circumstances, the present inventors conducted intensive research and found that cosmetics containing fine-particle metal oxides (preferably metal oxides having an average particle size of 0.01 to 0.1 µm) By containing 30% by mass of silicone oil, compared to the case where hydrocarbons, ester oils, etc. are contained, the transparency is excellent and the surface of the molded product is excellent in smoothness. It was found that the removal efficiency was improved and the shrinkage of the molded product after drying could be suppressed. Furthermore, the present inventors have clarified that the absence of squeaky feeling and impact resistance required of solid powder cosmetics are not sufficient only by containing fine particles of metal oxide and silicone oil in solid powder cosmetics. .

Therefore, as a result of further intensive research, the present inventors have found that the squeaky feeling of fine metal oxide particles can be reduced by containing amino-modified silicone-treated powder having a cationic group, and silicone oil can be added to the specified amount. It was found that the decrease in impact resistance due to inclusion is improved.
For this reason, the present inventors have found that by using (A) fine metal oxide particles, (B) amino-modified silicone-treated powder, and (C) a specific amount of silicone oil, excellent transparency and squeaky feeling can be achieved. The present inventors have found that it is possible to obtain a solid powder cosmetic which is excellent in smoothness of the surface of the molded product, does not cause shrinkage of the molded product, and has excellent impact resistance. This has led the inventors to complete the present invention.

7 L of water and 1 kg of talc (JA-13R: average particle size (D50) 5 to 8 μm, manufactured by Asada Flour Milling Co., Ltd.) were charged in a PE container with a capacity of 20 liters, and mixed with a disper mixer (Primemix; AM-40). Dispersed at 2000 rpm for 5 minutes. 103 g of the above dimethiconol emulsion was added and stirred at 2500 rpm for 5 minutes. Next, 96 g of a 5 mass % aqueous solution of aminopropyltriethoxysilane (KBE-903; manufactured by Shin-Etsu Chemical Co., Ltd.) was added as a cross-linking agent. After adjusting the pH to 10.3 with a 1N-NaOH aqueous solution, the mixture was stirred and reacted at 3000 rpm for 30 minutes. After filtering with a centrifugal dehydrator and washing with 7 L of water, the dehydrated cake was dried at 120° C. for 16 hours in a dryer. At this time, when the temperature was recorded by inserting a temperature sensor into the cake, it was found that the cake was heated at 115° C. or higher for 7 hours. The dried cake was pulverized with a pulverizer to obtain powdery amino-modified silicone-treated mica (2) (surface coating amount: 5%).

As described above, amino-modified silicone having a crosslinked structure obtained from dimethiconol and aminopropyltriethoxysilane was used as a surface treatment agent. was dimethiconol/aminopropyltriethoxysilane=100/10 (surface coating agent (a)/surface coating agent (b)=100/10).
In addition, the slightly crosslinked silicone product has a soft rubber hardness value of less than 5, a complex elastic modulus of 10,000 to 100,000 Pa in dynamic viscoelasticity measurement (25°C, strain rate of 17%, shear frequency of 4 Hz), and a loss factor. It is desirable to adjust the tan δ to 1.0 to 2.0.

Moreover, it is desirable to use silicone oil having an average molecular weight of 500 to 15,000.

As is clear from the results in Table 1, Examples 1 to 15 and 19 to 23 are excellent in transparency, have no squeaky feeling, and have excellent smoothness on the surface of the molded product. It was a cosmetic with excellent properties.
On the other hand, Comparative Example 1, in which a large amount of titanium oxide (No. 2) having an average particle size of 0.25 μm as component (F) was used alone in place of component (A), had a film whiteness derived from its optical properties. Loss of transparency. In Comparative Examples 2 and 3, which did not contain the component (B), the squeaky feeling derived from the fine metal oxide particles could not be suppressed, and the surface smoothness and impact resistance of the moldings were inferior. Comparative Example 4, in which an ester oil was used instead of the component (C), was significantly inferior in the smoothness of the surface of the molded product, no shrinkage of the molded product, and impact resistance due to the influence of the high bonding strength with the powder. It was something. In addition, in Comparative Example 5, in which a large amount of component (C) was blended, the removal efficiency of the solvent deteriorated due to the progress of wetting of the powder with the oil agent, resulting in shrinkage of the molded product and accompanying decrease in impact resistance. became.

For this reason, in order to obtain a solid powder cosmetic that has excellent transparency, no squeaky feeling, excellent surface smoothness of the molded product, no shrinkage of the molded product and excellent impact resistance, (A) is required. It was considered important to use fine-particle metal oxide, (B) amino-modified silicone-treated powder, and (C) silicone oil.
Furthermore, in order to obtain a more remarkable effect, a partially crosslinked organopolysiloxane polymer as component (D), (fluorination/hydroxylation/oxidation)/(Mg/K/silicon) as component (E), component ( They thought that it would be preferable to further use one or more selected from metal oxides with large particle sizes as F) and boron nitride as component (G) in the solid powder cosmetic. In order to obtain a more remarkable effect, it is preferable to include phenyl-modified silicone in the component (C) silicone oil, and the content ratio of phenyl-modified silicone/component (C) silicone oil is preferably was considered to be greater than or equal to 0.3, more preferably between 0.3 and 0.9.
In addition, in order to obtain a more remarkable effect, as a mass ratio when blending the components, the content mass ratio of the component (A) and the component (C) is (C) / (A) = 0.6 to 15. and/or that the content mass ratio of the component (C) in the total oil agent is component (C)/total blended oil agent = 0.6 to 1.0. .
