Description

Technical Field

[0001] The invention relates to a dispersible powder and a cosmetic containing the dispersible powder. Background Art

[0002] Conventionally, studies have been conducted on the improvement of the dispersibility of powders and their application when blended in compositions.

[0003] For example, studies have been conducted to improve dispersibility in aqueous media or oils by surface treatment of powders. Patent Document 1 describes that silsesquioxane particles are treated with silicone to improve dispersibility in silicone oil, but does not describe dispersion in aqueous media. In addition, there is no description of the effects and usefulness of the silsesquioxane when blended into a composition, particularly a cosmetic composition.

[0004] Patent Document 2 describes a method of hydrophilizing the surface of a pigment using a silane compound having a polyoxyalkylene group. However, since the surface hydrophilicity becomes too high, powder agglomerates, or the texture deteriorates when the pigment is mixed in cosmetics and applied.

[0005] Furthermore, Patent Documents 3 and 4 describe a water-based cosmetic containing a high HLB surfactant and a powder, wherein the high HLB surfactant and the powder are mixed in a cosmetic composition to prepare the cosmetic, but such a method cannot suppress the aggregation of the powders, so there are problems such as poor spreading and extension during application. Furthermore, Patent Document 5 shows a powder having a phosphorylcholine group introduced on the surface of the powder. However, although the powder is dispersible in water, due to the high hydrophilicity of the surface, there are problems such as aggregation and poor stability over time, and absorption of moisture in the air, resulting in a thick feeling when used.

[0014] The present invention has been made in view of the above problems, and its object is to provide a dispersible powder having excellent dispersibility and high dispersion stability, particularly in an aqueous medium. In addition, the present invention also aims to provide a cosmetic product containing the powder, which has a uniform makeup film, good spreading, extension, adherence, and use feeling during application, and high stability.

[0015] Technical means to solve technical problems

[0021] In addition, it is preferred that the nonionic surfactant is polyglycerol fatty acid ester.

[0022] In this case, it is preferred that the polyglyceryl fatty acid ester is polyglyceryl isostearate.

[0034] This can provide a cosmetic product that has a good feel during use and is excellent in usability and long-lasting properties.

[0035] Effects of the Invention

[0036] As described above, the dispersible powder of the present invention has excellent dispersibility and high dispersion stability, and when blended into cosmetics, the cosmetic film is uniform, spreads well during application, and has good ductility, adherence, and feel during use. DETAILED DESCRIPTION

[0037] As described above, there is a need for a dispersible treated powder having excellent dispersibility and high dispersion stability, and a cosmetic containing the powder, which has a uniform makeup film, good spreading when applied, good ductility, good adhesion, and good feel during use.

Among them, the solution polymerization method is preferred because it is easy to appropriately adjust the variance of the graph of gel permeation chromatography (GPC) when investigating the obtained weight average molecular weight and the weight average molecular weight of the copolymer.

[0060] As the solvent used in the polymerization, the polymerization reaction can be carried out in an aliphatic organic solvent such as pentane, hexane, decane, dodecane, hexadecane, octadecane, etc.; an aromatic organic solvent such as benzene, toluene, xylene, etc.; an alcohol organic solvent such as methanol, ethanol, propanol, butanol, hexanol, decanol, etc.; a halogenated organic solvent such as chloroform, carbon tetrachloride, etc.; a ketone organic solvent such as acetone, methyl ethyl ketone, etc. However, from the perspective of use in cosmetics, it is preferred to use no solvent or to use ethanol or isopropanol.

If the weight average molecular weight is 5,000 or more, good dispersibility in cosmetics can be surely exhibited. In addition, if the weight average molecular weight is 2,000,000 or less, it will not feel sticky or heavy. In addition, the weight average molecular weight in the present invention can be obtained as a weight average molecular weight converted to polystyrene analyzed by gel permeation chromatography (GPC) (the same applies hereinafter).

In the present invention, the HLB of the nonionic surfactant is preferably 8 to 18, and more preferably 8 to 16. When the HLB is 8 or more, there is no need to worry that the affinity of the dispersible powder to the aqueous medium is reduced and becomes difficult to disperse. In addition, when the HLB is 18 or less, the surfactant will not significantly detach from the dispersible powder, and there is no need to worry that the dispersion of the dispersible powder in the aqueous medium becomes difficult. In addition, the HLB value in the present invention can be set to a value calculated by the Griffin formula, for example.

The powder was dispersed in water, but agglomerated over time. In addition, if it was left as it was, it would absorb moisture in the air and become a sticky powder.

[0168] [Chemical formula 4]

[0169]

[0170] <Examples 11, 12, Comparative Examples 7 to 9>

[0171] The dispersions shown in Table 1 were prepared and their dispersibility was evaluated.

[0172] [Evaluation method]

[0173] The powder was dispersed in water and ethanol at the ratio shown in Table 1 below, and stored in a constant temperature bath set at 25°C, 50°C, and -5°C. It was stored in a constant temperature bath at 25°C for 2 hours immediately after preparation, and was taken out after 1 week of storage and stored in a constant temperature bath at 25°C for 2 hours. After the above 2 hours of storage, the sample bottle was shaken 10 times and this was set as one set. After each set, the powder was visually evaluated for aggregation.

[0174] [Evaluation criteria]

[0175] ○: Dispersion during 1-2 groups of vibrations

[0176] ×: Dispersion when oscillating more than 3 groups

[0177] [Table 1]

[0178]

[0179] ※No: It is not dispersed during production.

[0180] The mixing ratio of each component was adjusted so that the total amount would be 100.

[0181] As shown in Table 1, it can be confirmed that Examples 11 and 12 using the dispersible powder of the present invention have excellent dispersibility and high dispersion stability. Comparative Example 8 itself could not be produced, and Comparative Example 9 was dispersed immediately after production, but precipitation and agglomeration occurred over time, making it difficult to disperse. In addition, even if only a nonionic surfactant was used for surface treatment as in Comparative Example 7, the dispersibility would not be improved. It can be seen from this that the present invention has high dispersion stability by using a (meth)acrylic acid (co)polymer containing a repeating unit having a phosphorylcholine group for surface treatment.

[0182] <Examples 13 to 18, Comparative Examples 10 to 16>

[0183] The lotions shown in Table 2 were prepared by a conventional method, and their usability was evaluated.

[0184] [Sensory evaluation method]

[0185] About 5 g of the lotion obtained by the ratio shown in Table 2 below was applied to the skin, and the spreading, uniformity and extension were evaluated for sensory evaluation during application. In addition, the spreading during application indicates the smoothness (lightness) and smoothness during application, and the smearing feeling, and the extension indicates the physical development length and area. In addition, for dispersion stability, the powder was visually evaluated from the appearance of the product 1 week after production to see whether it agglomerated. The results are shown according to the following evaluation criteria based on the number of assessors who answered "effective".

[0186] [Evaluation criteria]

[0187] ◎: 4-5 people answered that it was effective

[0188] ○: 3 people answered that it was effective

[0189] △: 2 people answered that it was effective

[0190] ×: 1 person or no one answered that it was effective

[0191] [Table 2]

[0192]

[0193] The mixing ratio of each component was adjusted so that the total amount would be 100.

[0194] As shown in Table 2, it can be confirmed that the lotions of Examples 13 to 18 using the dispersible powder of the present invention have very excellent dispersibility, high dispersion stability, uniform makeup films, good spreadability during application, and good spreading.

[0195] On the other hand, in Comparative Examples 10 to 16, the powders obtained in Comparative Examples 1 to 6 were used, and the dispersion stability, spreading during application, uniformity, and extension were poor. As can be seen from the above, the dispersible powder of the present invention has excellent dispersibility and high dispersion stability, and when it is blended into cosmetics, the cosmetic film is uniform, the spreading during application and extension become good, and the feeling of use is improved.
