Description

  The present invention relates to a powder cosmetic containing one or more selected from titanium metal and zinc oxide having an average particle size of 0.01 to 0.2 μm and a polyurethane gel composition. More specifically, the present invention relates to a powder cosmetic excellent in uniform removal to a prop, moist feeling, uniformity of a cosmetic film, and no dry feeling over time.

  Powder cosmetics are widely used in basic cosmetics such as makeup cosmetics such as foundation, white powder, eye color, teak color, and eyebrow, body powder, and whitening powder because of ease of use. In general, titanium oxide and zinc oxide with an average particle diameter of about 0.25 μm, which has high hiding power, are used to make the skin color unevenness and pores inconspicuous. In order to achieve a transparent finish with no white film feeling, a technique using titanium oxide and zinc oxide having an average particle size smaller than that of conventionally used titanium oxide and zinc oxide has been studied (Patent Document 1). ). However, a metal oxide having a small particle size has a strong cohesive force, and when it is contained in a powder cosmetic, a squeaky sensation is produced, and there is no moist sensation.

  In order to solve the above problems related to the feeling of use, various studies have been made. For example, a technique (Patent Document 2) combined with a sorbitan fatty acid ester and an acrylic / silicone copolymer, a technique used in combination with a spherical elastic resin powder (Patent Document 3), and the like have been proposed.

Japanese Patent Laying-Open No. 2015-168642 JP 2017-190299 A JP 2012-140340 A

  However, when the technique combined with sorbitan fatty acid ester and acrylic / silicone copolymer (Patent Document 2) is used, the moist feeling is improved, but the aggregation of the powder component is promoted, and it cannot be taken uniformly in the prop. There were cases where problems occurred. Further, in the technique used in combination with the spherical elastic resin powder (Patent Document 3), although the feeling of squeak is improved, the feeling of drying over time may be felt more.

  Accordingly, there is a need for a powder cosmetic that can be taken evenly by a small tool, has a moist feeling and a uniform cosmetic film, and does not feel dry over time.

  In such a situation, the present inventor uses a propeller by combining with other ingredients in a powder cosmetic containing one or more selected from titanium oxide and zinc oxide having an average particle size of 0.01 to 0.2 μm. In order to develop a powdery cosmetic material that can be removed evenly, with a moist feeling and excellent uniformity in the cosmetic film, and without a feeling of dryness over time, an extensive study was conducted. As a result, it has been found that by combining a novel polyurethane gel composition, a powder cosmetic can be obtained that is uniform in a prop, moist, and excellent in the uniformity of a cosmetic film and has no dry feeling over time. The research was completed.

[Measurement of load value and gel strength evaluation]
The polyurethane gel composition of Production Example 2 and various oil agents listed in Table 1 were heated and dissolved at 85 ° C. and cooled to 30 ° C. to prepare elastic gels (Test Examples 1 to 6). The load value of the gel was measured using a load measuring device (manufactured by FUDOH) under conditions of a 2 cmφ spherical adapter, 2 cm / min, and 10 mm penetration. This evaluated the gel strength. As a result of Test Examples 1 to 4, it was confirmed that an oil agent having a smaller number of hydroxyl groups in the molecule tends to have a higher load value. This is considered that the hydroxyl group in the oil agent affected the hydrophilic group portion in the hydrophilic group-associative thickening mechanism of the polyurethane gel, resulting in a decrease in viscosity.

[Measurement and evaluation of transparency]
Transparency with respect to various gels described in Table 1 (Test Examples 1 to 6) was measured for transmittance at 700 nm using a transmittance measuring machine (manufactured by Shimadzu Corporation). As a result, in all the gels of Test Examples 1 to 6, 90% or more and good transparency (◎) was shown.

[Measurement and evaluation of self-restoring force]
The self-restoring power was evaluated using the polyurethane gel composition of Production Example 2 and the dextrin fatty acid ester gel of Production Comparative Example 2. Each measurement sample is diluted with cetyl 2-ethylhexanoate so that the pure content is 10.5% by mass, heated at 85 ° C., poured into a jar, and cooled to 30 ° C. A gel was prepared. Using the texture analyzer (manufactured by Eisei Seiki Co., Ltd.) for the prepared sample, 7 times under the conditions of 1 mm / min speed and 5 mm penetration from the point of applying a load of 5 g with a 2 cmφ spherical adapter, By repeating the same operation, it was confirmed whether the gel structure was not destroyed by the load and had a restoring force. A schematic diagram of the measurement is shown in FIG.
As a result, the dextrin fatty acid ester gel of Production Comparative Example 2 breaks the gel structure with repeated loads and does not have the same curve, whereas the polyurethane gel composition of Production Example 2 has a gel with repeated loads. Since the same curve was traced without collapsing, it was found that the gel was highly recoverable. Moreover, since the value of load value itself was also high compared with the dextrin fatty acid ester gel of manufacture comparative example 2, it turned out that it is excellent in elasticity.

  From the above investigation, it was found that the component (A) polyurethane gel composition used in the present invention is a highly novel gel having excellent transparency and high elasticity and excellent self-restoring ability.
