Description

  The present invention relates to a powdery cosmetic comprising an oil-containing powder composition in which an oil agent is coated with a fluorine compound-treated powder and a water-containing powder composition in which water is coated with a hydrophobized powder. . The oil-containing powder composition and the water-containing powder composition both relate to a powdery cosmetic that is liquefied when applied to the skin. More specifically, it excels in state changes (liquefaction) on the skin, has a smooth feeling without stickiness, has an excellent effect of making pores and wrinkles inconspicuous, and is subject to vibrations and shocks during transportation and carrying. Also relates to a powdery cosmetic that can maintain a powder state.

  Powdery cosmetics are cosmetics with a powder as the main skeleton and a small amount of oil added as necessary. The continuous phase is air, and there is no oily stickiness and excellent use feeling. It is a cosmetic agent type. On the other hand, powdery cosmetics have the disadvantage of being inferior in sustainability of the makeup effect when used as a powdery cosmetic or makeup cosmetics. For this reason, attempts have been made to increase the amount of oil to be added in order to reduce the powderiness and increase the sustainability of the makeup effect without impairing the smooth feeling of use of the powdery cosmetic. However, simply increasing the amount of oil added to the powder causes the oil and powder to be kneaded, resulting in a cosmetic (so-called oily cosmetic) in which the continuous phase becomes oil, maintaining the powder state. It was difficult.

  In addition, when the amount of oil added to the powder cosmetic is gradually increased, the composition of the oil and powder becomes an intermediate region between the oil cosmetic and the solid powder cosmetic, and the quality in terms of moldability is improved. It becomes difficult to ensure. In addition, the cosmetics having the composition in this region cannot easily maintain the uniformity of the decorative film because the powder easily falls into the pores. However, various technologies have been developed for cosmetics having compositions in this region based on the technical prediction that cosmetics having excellent qualities of both oily cosmetics and solid powder cosmetics can be obtained.

Specifically, a technique for obtaining a water-containing powder cosmetic by adding water to an oil agent previously powdered with a fluorine compound-treated powder (see, for example, Patent Document 1), a fluorine compound-treated powder and a water-in-oil type The technique (for example, refer patent document 2) etc. which contain an emulsified composition and obtain powdery cosmetics are mentioned.
Japanese Patent No. 3107891 (pages 1 to 6) JP 2003-12450 A (page 1 to page 4)

  However, in the technique described in Patent Document 1, since a large amount of water is contained, there is a case where the feeling of smooth use is impaired although there is freshness. And in the technique of the said literature 2, since the surfactant for preparing a water-in-oil type emulsion composition contains, it is difficult to pulverize oil agent and water stably, and at the time of transportation and carrying Sometimes the powder state could not be maintained when subjected to vibration or impact.

  For this reason, it excels in state changes (liquefaction) on the skin, has a smooth feel without stickiness, has an excellent effect of making pores and wrinkles inconspicuous, and even when subjected to vibration or impact during transportation or carrying Development of a powdery cosmetic that can maintain the state has been desired.

  In view of such circumstances, the present inventors have conducted intensive studies, and as a result, separately contained an oil-containing powder composition in which an oil agent was coated with a fluorine compound-treated powder and a water-containing powder composition in which water was coated with a hydrophobized powder. It was found that by preparing and blending both in combination, a powdery cosmetic material that solves the above problems can be obtained, and the present invention has been completed.

That is, the present invention comprises the following components (a) and (b):
(A) an oil-containing powder composition in which an oil agent is coated with a fluorine compound-treated powder; (b) a powdery cosmetic comprising a water-containing powder composition in which water is coated with a hydrophobized powder; The content of the oil agent is 10 to 75% by mass, and the content of water is 0.3 to 20% by mass.

  Such silicone waxes having a melting point of 15 to 40 ° C. are commercially available products such as stearyl dimethicone DC2503 (melting point 32 ° C .: manufactured by Toray Dow Corning Silicone), SDM5055VP (melting point 30 ° C .: manufactured by Asahi Kasei Wacker Silicone), etc. And silicone wax.

  The reason why it is preferable to contain a silicone wax having a melting point of 15 to 40 ° C. in the oil used for component (a) is that the crystal part (site of alkyl, higher fatty acid, higher alcohol, etc.) and the amorphous part in the molecule This is because (organopolysiloxane site) coexists, so that it instantaneously melts on the skin. Furthermore, the silicone wax having a melting point of 15 to 40 ° C. is particularly preferably one having a sharp endothermic / exothermic peak of DSC (differential scanning calorimetry).

When the water content is in this range, a powdery cosmetic material that is particularly excellent in the effect of making pores and wrinkles inconspicuous can be obtained. In addition, the water in the component (b) is partly hydrophilic because the water is repelled on the skin by the cosmetic application operation, and the powder does not fall into the pores due to the powder remaining on the skin. As a result, pores are not conspicuous, and there is an effect of improving the uniformity of the decorative film.

  Furthermore, the component (b) contains a water-soluble polymer and gels, thickens, and solidifies the water, thereby improving the impact resistance of the hydrous powder composition (impact when filling into a container, transport impact, etc.). Can be increased. Such a water-soluble polymer gels water by dissolving or swelling in water.

The water-soluble polymer is preferably contained in the component (b) in an amount of 0.01 to 5%.

  The blending mass ratio (a) / (b) of the powder composition of the component (a) and the powder composition of the component (b) in the powder cosmetic of the present invention is such that the content of the oil agent in the total powder cosmetic is It is preferable to mix | blend so that it may become 10 to 75% and content of water 0.3 to 20%, It is preferable that (a) / (b) is 99.5 / 0.5-30 / 70. .

  The powdery cosmetic of the present invention is a powder other than the fluorine compound-treated powder, polyhydric alcohol, surfactant, moisturizing component, as a component usually contained in the cosmetic, as long as the effects of the present invention are not impaired. Water-soluble polymers, antioxidants, preservatives, drugs, fragrances and the like can be added and mixed to form a powder cosmetic.

  The powdery cosmetic of the present invention can be applied to makeup cosmetics such as eye color, foundation, blusher, white powder, pore concealment, base makeup, skin care cosmetics such as cleansing and body powder, sunscreen cosmetics, and the like.

  Hereinafter, the present invention will be described in more detail with reference to examples. Note that these do not limit the present invention.
