Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil-based water-based cosmetic, and more particularly to an oil-based water-based cosmetic having a good feeling of use or stability. [Prior Art] Conventionally, since the agglomerating power of the fine particle powder is strong, it is necessary to carry out a medium-type wet dispersion treatment such as ball milling using a large amount of the powder dispersing agent to be contained in the cosmetic material. As a powder dispersing agent, a high molecular weight surfactant having high dispersibility can be preferably used. However, when it is contained in a large amount, there may be a feeling of "stickiness" or "poor expansion" in the feeling of use, and When the content of the powder dispersant is reduced to improve the feeling of use, the powders are agglomerated with each other. As a result, the viscosity of the product increases, gelation, and liquid discharge may occur. In particular, in the oil-based water-based cosmetic, the use of the powder dispersant affects the emulsification system. In some cases, emulsification at the time of emulsification may occur, or aggregation or merging of emulsified droplets may occur over time. In recent years, 'products with high SPF 値 (UV defensive index) in sunscreen cosmetics have been put on the market. These are used in combination with ultraviolet absorbers and fine particle powders such as titanium oxide or zinc oxide, and almost all of them are used to improve SPF 値. The microparticle powder is contained in a highly dispersed state. Further, when the fine particles are contained, when they are dispersed in the water system, a feeling of "friction" may be felt when using the feeling, and it may be better to disperse in the oil system. Various techniques for dispersing fine particle powders in an oil system have been proposed in the past, and a combination of a surface-treated powder and an oxime oil and a specific ketone-based surfactant to obtain an oil-type emulsifier in an oil of 1137292 There is a Japanese Patent Publication No. 63-215615, but the effect of sufficient stability or feeling of use may not be obtained. Further, a method of obtaining a water-type emulsifier in a stable oil by a combination of a surface-treated fine particle powder of an organic cerium compound and an oxime oil and a specific ketone-based surfactant containing a long chain is disclosed in Japanese Patent Application No. 2001-278737 Proposal such as the bulletin. However, it is necessary to use a specific surfactant, and sometimes there is a limitation in the adjustment of the feeling of use. Therefore, in the case of a water-based cosmetic in an oil containing a fine particle powder, it is desired to develop a cosmetic which is not only stable in stability but also has a good feeling in use. DISCLOSURE OF THE INVENTION PROBLEM TO BE SOLVED BY THE INVENTION An object of the present invention is to provide an oil-in-water cosmetic which is blended with a finely pulverized powder of an organic cerium compound and which is easy to stretch and has no sticky feeling. Good, and good stability over time. (Means for Solving the Problem) In order to solve the above problems, the inventors of the present invention have found that a microparticle powder containing a specific amount of an organic cerium compound as a surface treatment, an oxime oil, and a specific one have been found. The lipophilic surfactant, the specific organic ketone ketone resin, and the water-based oil-based cosmetic are excellent in feeling of use (easily stretchable and non-sticky), and have good stability over time, and have completed the present invention. That is, the present invention is an oil-in-water cosmetic comprising: (a) an organic cerium compound having a mass of 10 to 30% by mass of 1317292 with respect to the fine particle powder (mother powder) before surface treatment, and surface treatment is carried out. The fine particle powder, (b) anthrone oil, (c) an oleophilic surfactant of HLB 2 to 7, (d) the structural unit is an organic fluorenone resin of the following formula (1), and (e) water. RVSiO ('Liu formula (1) (wherein R1 represents a hydroxyl group having a carbon number of 1 to 6, and η represents a charge of 1.0 to 1, 8). Further, it is an oily water-based cosmetic in which U) is a component The organic hydrazine compound is a reactive alkyl polyoxyalkylene. Further, it is an oil-in-water cosmetic wherein the organic bismuth compound in the component (a) is a reactive alkyl polyoxyalkylene and a methyl hydrogen polyoxygen. Further, it is an oil-in-water cosmetic in which the content of the surface-treated fine particle powder of the component (a) is from 1 to 50% by mass based on the total amount of the water-based cosmetic in the oil. Further, it is an oil-in-water cosmetic in which the surface-treated fine particle powder of the component (4) is further treated with a fatty acid as a surface. Further, the present invention is an oil-in-water cosmetic, wherein the surface-treated fine particle of the component (4) is selected from the group consisting of titanium oxide, zinc oxide, and cerium oxide, or two or more kinds thereof. Further, 'an oil-based cosmetic, wherein the ketone oil of the component (b) is a volatile ketone oil. Further, it is an oil-in-water cosmetic, wherein the (e) component of the lipophilic surfactant is an anthrone-based surfactant. Further, it is an oil-in-water cosmetic, wherein the mass ratio of the component (4) to the component (4) is (a)/(d) = l〇/i. [Embodiment] Hereinafter, the configuration of the present invention will be described. 1317292 The component (a) used in the present invention is a microparticle powder which is surface-treated with an organic cerium compound, and is mainly contained in an oil system, and the purpose thereof is different depending on the type of the powder, and is used as a defense effect, coloring, and touch adjustment of ultraviolet rays. Wait for the purpose. Further, in the present invention, the surface treatment refers to the surface of the particles coated with the fine particle powder with an organic cerium compound. In the fine particle powder in which the component (a) is subjected to surface treatment with an organic cerium compound, the average particle diameter of the powder to be treated (mother powder) is not particularly limited as long as it is in the range of 500 nm, and preferably average The particle diameter ranges from 5 to 100 nm. Specific examples of the powder to be used in the present invention include, for example, titanium oxide, zinc oxide, oxidized pin, cerium oxide, and the like, and the coloring agent is, for example, iron oxide or the like, and as a feeling adjusting agent, for example. , anhydrous cerium oxide, barium sulfate, and the like. The shape of the powders is, for example, a spherical shape, a needle shape, a spindle shape, a plate shape, or a sheet shape. Further, the average particle diameter of the powder of the needle shape, the spindle shape, the plate shape, and the flake shape indicates the average length of the longest side. Among these, the fine particle powder having a high effect by treating with an organic cerium compound is, for example, titanium oxide having a surface activity, zinc oxide or cerium oxide. Further, for the purpose of reducing the surface activity of the powders, it is also possible to treat them with an inorganic component such as cerium oxide, aluminum oxide or an oxidation pin. The granule powders which are surface-treated with the organic ruthenium compound may be used singly or in combination of two or more kinds as needed. In addition, the method of measuring the average particle diameter of the powder, for example, the length of the fine particle powder can be measured by an electron microscope, or can be obtained by a commercially available particle size measuring instrument such as a Coulter counter (manufactured by COULTER ELECTRONICS CO., LTD.). The component used in the invention (a) The surface treatment amount of the 1372992 microparticle powder which is surface-treated with the organic cerium compound is 10 to 30% by mass or less based on the mass of the granule powder (mother powder) before the surface treatment. It is expressed by "%", and in this specification, "% by mass" is synonymous with "% by weight", and more preferably 13 to 20%. When the amount of the organic cerium compound to be treated is less than 10% by mass based on the mass of the fine particle powder (parent powder) before the surface treatment, the "wetting property" of the powder dispersion medium is not good, and sufficient dispersibility may not be obtained. On the other hand, if the mass of the fine particle powder (mother powder) before the surface treatment exceeds 30% by mass, the excess organic hydrazine compound may affect the stability of the entire system. The organic ruthenium compound of the component (a) used in the present invention is, for example, an alkoxy-denatured polysiloxane, a carboxyl-modified polyoxyalkylene, an epoxy-modified polyoxyalkylene, an amine-modified polyoxyalkylene, and a Hydrogen-denatured polyoxane and the like. More specifically, for example, the methyl hydrogen-denatured polyoxane represented by the following general formula (2) and the following general formula (3) are described in JP-A-11-148028.

The reactive alkyl polyoxyalkylene has, for example, dimethyl polydecyl decyl alkane, α-monoalkoxy polydimethyl siloxane, α-dialkoxy polydimethyl oxime An alkane, an α-trialkoxy polydimethyl methoxy alkane, and the like. Further, among these organic ruthenium compounds, in order to obtain more excellent powder dispersibility and stability, a reactive alkyl polyoxyalkylene is preferable, and a more preferable effect is obtained, and a reactive alkyl polyfluorene is used for hydrazine. Oxyalkane and methylhydrogenpolyoxyalkylene are more preferred. These organic hydrazine compounds may be used alone or in combination of two or more. 1317292
