Description

  The present invention relates to a solid powder cosmetic.

  The solid powder cosmetic manufacturing method includes a dry method in which powder and an oil agent as a binder are mixed and then compacted, and a volatile solvent is added to a cosmetic base material composed of powder and oil to form a slurry, which is then filled into a container. Then, there is a wet method in which a volatile solvent is removed by drying to obtain a cosmetic. The solid powder cosmetic obtained by the wet method is in a slurry state, so that the uniform dispersion of the powder and the oil advances, and has a fine powder quality and a moist feeling. In the wet method, it is necessary to uniformly disperse the base powder and oil in the slurry in order to maximize the characteristics. As such a solvent excellent in the dispersion ability of the base material, volatile hydrocarbons and low-boiling alcohols are known, and are widely used for obtaining solid powder cosmetics by an actual wet method (Patent Document 1). 2).

  However, volatile hydrocarbons and low-boiling alcohols are dangerous, so when used in the production of solid powder cosmetics, they should be used after being managed with a special storage warehouse. It was necessary to pay attention in terms of work safety and environmental measures, such as setting the drying conditions so as not to exceed the point, and recovering and disposing of the volatile solvent removed by drying again. In addition, volatile hydrocarbons obtained by refining petroleum cannot be used when petroleum is depleted in the future.

  From such a background, it has been attempted to use water as a volatile solvent. However, when water is used to prepare a slurry, it is difficult to uniformly disperse the oil agent, and the resulting product is from the surface to the inside. The oil dispersion state becomes uneven, and there are problems in use such as the amount of powder removal and spreading to the skin differing depending on the location of the cosmetic used, and the impact resistance is poor.

As a procedure of a wet method using water, first, a powder and an oil agent which are cosmetic base materials are stirred and mixed with a stirring mixer such as a Henschel mixer, and pulverized and dispersed with a hammer mill. The oil agent is evenly adsorbed on the surface. Next, water is added and slurried with a kneader. At that time, the oil agent uniformly adsorbed on the powder causes aggregation or large aggregates deviate from the powder surface, and the dispersion solvent Separate into the water. Such a mechanism is considered to cause deterioration in the feeling of use and impact resistance as described above.
In particular, in a product containing a lot of glitter pigments, the above phenomenon is remarkable, it is difficult to ensure impact resistance, and this is a problem in a wet method using water as a volatile solvent.

  In order to solve such problems, the impact resistance is improved by suppressing the blending amount of oil agents with poor dispersibility and using solid powder oil (Patent Document 3) or containing a film-forming polymer. Attempts have been made (Patent Document 4).

Japanese Patent Application Laid-Open No. 64-9909 Japanese Patent Publication No. 06-104612 JP 2007-269696 A Japanese Patent No. 3455476

However, as in Patent Documents 3 and 4, when solid powder oil or a film-forming polymer is used in the base material, although impact resistance is improved, it is derived from these components and is powdery. It becomes a bad feeling of use.
As described above, among wet-filled solid powder cosmetics using water, especially those containing a lot of glitter pigments, development of a formulation having excellent usability and sufficient impact resistance is awaited. .

  As a result of intensive studies in view of the above circumstances, the present inventor uses one or more selected from a specific oil agent and glitter pigment, glycol and an amphiphilic ester at a specific ratio. The oil agent can be uniformly present on the powder surface even in the slurry prepared using water, and since the oil agent does not deviate from the powder surface, the solid is excellent in feeling of use and has sufficient impact resistance. It has been found that a powder cosmetic can be obtained.

In the present invention, a cosmetic base material containing a powder and an oil agent, and a single or two or more mixed solvents selected from water and an aqueous solvent are mixed to form a slurry, filled in a container, and then the solvent is added. A solid powder cosmetic obtained by removing the following components (A), (B) and (C):
(A) Oil agent which is liquid or pasty at 25 ° C. having a hydroxyl group in the molecule: 5 to 20% by mass of the total amount of the cosmetic base material,

The IOB value is an index for predicting the physical properties of organic compounds, and is described in “Fragrance Journal”, vol. 50, pp. 79-82 (1981) and the like, the scores of “organic value (IV)” and “inorganic value (OV)” were added to each part of the structure of the compound and added together to obtain the total IV score. It is obtained as a value divided by the OV score. Van Der Waals force is considered to be “organic” in terms of physical properties and “inorganic” in terms of physical properties due to electrical affinity. Compounds with higher IOB values are more likely to cause electrical interactions Is done.

  The oil agent of component (A) can be used singly or in combination of two or more, and the content is 5% by mass or more in the total amount of the cosmetic base material from the viewpoint of feeling of use and impact resistance. 6 mass% or more is preferable and 7 mass% or more is more preferable. And from the point of the amount of taking powder of cosmetics, and the moist feeling of application, it is 20 mass% or less in cosmetics base material total amount, 18 mass% or less is preferred, and 15 mass% or less is more preferred. Moreover, content of the oil agent of a component (A) is 5-20 mass% in cosmetics base material total amount, 6-18 mass% is preferable, and 7-15 mass% is more preferable.

  Since the outermost layer is coated with one or more selected from titanium oxide, iron oxide and silica, the bright pigment has a hydroxyl group on the outermost layer, and thus has an affinity for the component (A) oil agent. Is expensive. Therefore, when preparing a slurry by stirring and mixing a cosmetic base material containing these pigments and water, the deviation of the oil agent from the powder surface does not occur, and when it finally becomes a solid powder cosmetic. Also, it has a moist feeling of use derived from the oil agent and sufficient impact resistance.

  The glitter pigment of component (B) can be used singly or in combination of two or more, and the content is 30% by mass or more in the total amount of the cosmetic base material from the viewpoint that sufficient glitter is obtained.
