Description

  The present invention relates to a cosmetic, and more particularly, to a method for producing a cosmetic suitable for a cosmetic having characteristics such as a three-dimensional shape or a multicolor structure, and a cosmetic produced by the production method.

  In cosmetics, especially makeup cosmetics, the product form has a multicolor structure, a structure with a three-dimensional feature, or a highly designed product, which increases the incentive to use. At the same time, it is known to enhance the satisfaction of the makeup finish. In addition, with multicolor cosmetics, the color can be formulated as the user desires, so the actual color rendering itself is also increasing. From such a point of view, attempts have been made to produce a makeup product having a shape with high designability. (For example, see Patent Document 1, Patent Document 2, and Patent Document 3) However, although such a technique also realizes multicolor cosmetics and three-dimensional cosmetics, it can be added to a conventional metal pan. It was hard to say that the difference from the pressed one was so large.

  As a method for significantly improving the designability, a technique has been developed in which granules are made using the binder properties of gypsum, the granules are molded in a wet state, and dried and solidified. (For example, refer to Patent Document 4, Patent Document 5, and Patent Document 6) Although the design property is remarkably increased by this method, the loss of usability derived from gypsum is in a situation that cannot be denied, and the effect of gypsum on the usability The development of technology to reduce the demand has been desired.

  Mica and mica titania, which may be surface-treated, are spherical powders, and oil that is liquid at 1 atm. 25 ° C. is a component commonly used in the field of cosmetics. 1) Surface treatment 30 to 60% by mass of mica and / or mica titania that may be used, 2) 5 to 15% by mass of spherical powder, and 3) 10 to 20% by mass of oil that is liquid at 1 atmosphere and 25 ° C. There are no known cosmetics processed from granulated products. It has not been known at all that a cosmetic material excellent in design and usability can be obtained by passing through such a granulated product.

As the surface treatment, a coloring treatment such as red 226 or the like, a coloring treatment with a metal oxide such as iron oxide, a baking treatment with methicone or dimethicone, a metal soap coating treatment, an acyl glutamate coating treatment, a phospholipid coating treatment, or the like is preferable. It can be illustrated. Such surface treatment is preferably performed in an amount of 1 to 40% by mass with respect to mica and / or mica titania. The mica titania may or may not have a pearl feeling as long as it has a form in which mica is used as a base and titanium dioxide is coated, but a substance having a pearl feeling is preferable. Mica titania having a pearly feeling includes an iris foil. Such mica or mica titania already has a commercial product as a raw material for cosmetics, and such a commercial product can be purchased and used. In the present invention, such mica and / or mica titania has an effect of optically imparting a glossy feeling, and exhibits such adhesiveness that occurs when such powders intervene oil. It has the effect | action which produces the stress which forms a granule using. Thereby, in order to express such an effect with the binder between powder, the said content is needed.

  The granulation composition of this invention can be manufactured by granulating the said component with arbitrary components. The granulation is not particularly limited as long as it is a generally known method, and examples thereof include fluidized bed granulation, rolling bed granulation, extrusion granulation, and so on. The shape can be made uniform to the particle size by using NIPPOUDAL Co., Ltd. For such granulation, for example, volatile components such as water and ethanol can be added, and such volatile components are intervened only at the time of granulation, and then volatilized, so that appropriate binding is achieved. Can be formed. If desired, gypsum can be added at this time to increase the binding force. The gypsum is preferably at most 10% by mass of the total mass. If it exceeds this, the usability may be impaired. It is preferable that the granulated composition thus produced is appropriately sized and classified to match the particle size.

<Test Example 1>
The usability of the eye color 1 and the comparative eye color 1 was tested using the change in state under continuous use as an index. The change in the state is considered as the change in the gloss value that shows the appearance of shine and the change in the amount of powder taken when using a puff, and the gloss at the start of use and the gloss after 20 consecutive uses with respect to the amount taken. And observed as a change in yield. As the gloss value, a gloss value (Gs (45 °)) of 45 degrees incident and 45 degrees received by a gloss meter VGS-SENSOR (manufactured by Nippon Denshoku Industries Co., Ltd.) was used. The results are shown in Table 1.
