Description

  The present invention relates to a powder for cosmetics and a cosmetic containing the powders.

  Solid powder cosmetics obtained by pressure-molding powders coated with fats and oils have an advantage that a beautiful finish can be achieved with a simple cosmetic operation, and thus have been widely used as foundations and the like. On the other hand, there were also disadvantages such as a dry feeling due to the oil-absorbing property of the powder and a tendency to break the makeup. Regarding dry feeling, the dry feeling was remarkably reduced by applying silicone treatment such as baking with hydrogenmethylpolysiloxane to the powder and coating the powder with an oil component (see, for example, Patent Document 1). ). With regard to cosmetic break-up, it has been improved by improving the adhesion of the cosmetic film by surface treatment with silicone and coating with high-viscosity oils. However, practical retouching is performed more frequently than emulsified foundations. It was the current situation that had to be done. That is, it is presumed that there are factors that cause makeup collapse that cannot be solved by imparting hydrophobicity to the powder or imparting tackiness to the powder with an oily substance. That is, it can be said that the development of a technique for further improving the longevity of the makeup in the solid powder cosmetic is desired. Such a tendency is particularly prominent in cosmetics containing a large amount of plate-like powder such as sericite and mica. This is because an aqueous component such as sweat accumulates between the plate-like powder and the skin, and the powder slides and moves on the surface of the stored aqueous component because of the hydrophobic property of the powder. It is estimated.

  On the other hand, a technique for incorporating royal jelly into cosmetics is already known, and a 57-kilodalton glycoprotein called “roylactin” is known as a substance responsible for various actions possessed by royal jelly. Such a component is specified by the molecular size and the amino acid sequence of “Asn Ile Leu Arg Gly Glu Ser Leu Leu Lys Lys Leu Pro Ile Leu His Glu Met Lys Phe Phe Asp Tyr Xaa Asp” at the N-terminus. Xaa represents an unknown amino acid (see, for example, Patent Document 2, Patent Document 3, and Patent Document 4). However, there is no known technique for coating powder with royal jelly, and by covering sericite or mica with royal jelly, the composite powder has a significantly longer makeup than hydrophobic treatment such as silicone treatment. It was not known at all that it could be improved.

Japanese Patent Laid-Open No. 03-9964 JP 2003-000162 A JP 2002-335883 A JP 2002-199849 A

  The present invention has been made under such circumstances, and an object of the present invention is to provide a technique for improving the longevity of powders such as sericite and mica.

In view of such a situation, the present inventors sought for a technique for improving the makeup of powders such as sericite and mica, and as a result of earnest research efforts, by coating with royal jelly, We have found that such improvement in makeup can be achieved, and have completed the invention. That is, the present invention is as follows.
(1) 1) royal jelly and / or its extract, 2) sericite and / or mica powder for coating to name Ru of粧料.
(2) The royal jelly contains a glycoprotein of 57 kilodaltons in an amount of 9% by mass or more based on the total amount of protein contained in the royal jelly . powder.
(3) The powder for cosmetics according to (1) or (2), wherein the amount of the royal jelly is 0.1 to 10% by mass with respect to the total mass of the coated powder.
(4) (1) to (3) A cosmetic comprising the powder cosmetic of any crab described.
(5) The cosmetic according to (4), which is a powder solid cosmetic.

  According to the present invention, it is possible to provide a technique for improving the longevity of powders such as sericite and mica. In particular, it is possible to suppress collapse caused by water such as sweat and to significantly improve makeup retention.

(1) Cosmetic powder of the present invention The cosmetic powder of the present invention is characterized in that sericite or mica is coated with royal jelly. Weight ratio in the powder, based on the total weight of the coated powder, sericite or mica is 99 to 90 wt%, the Royaruzeri over 0. 1 to 10% by mass. The powder for cosmetics of the present invention can be manufactured by coating 0.1 to 10% by mass of royal jelly with respect to 90 to 99% by mass of sericite or mica. Such a coating can be produced by solubilizing or dispersing royal jelly in 1 to 10 times mass of solvent or dispersion medium, preferably coating at 20 ° C. or less, and removing the solvent under reduced pressure conditions. As such a solvent or dispersion medium, one or more selected from water, ethanol, isopropanol and butanol can be suitably exemplified.

As the royal jelly used for such coating, one having a high freshness is preferable because of its high effect, and the freshness can be distinguished by the content of royal lactin. That is, when the mass percentage of royal lactin with respect to the total protein contained in the royal jelly is 9% by mass or more, the royal jelly can be identified as fresh. Such loyalactin can be identified by confirming the following physical properties.
1) A single band is formed in non-denaturing polyacrylamide gel electrophoresis of proteins in royal jelly.
2) The molecular weight measured by SDS-polyacrylamide gel electrophoresis under reducing conditions is about 57 kilodaltons.
3) It has an amino acid sequence of “Asn Ile Leu Arg Gly Glu Ser Leu Leu Lys Lys Leu Pro Ile Leu His Glu Met Lys Phe Phe Asp Tyr Xaa Asp” at the N end.

  Further, the quantification of royalactin, which is such a glycoprotein, can be performed as follows. The structure of the protein is analyzed by electrophoresis, and the molecular weight of the protein as the active ingredient is specified. The method of electrophoresis is not particularly limited as long as the effective protein can be identified, but a preferable method is to convert a water-soluble royal jelly protein (3% royal jelly aqueous solution (W / V)) into a polyacrylamide gel (10% uniform). In this method, electrophoresis is performed at a current of 20 mA, and the protein is identified by staining with Coomassie Brilliant Blue. It can be quantified by calculating the staining intensity ratio of the 57 kilodalton band staining portion to the total staining portion.

(2) The cosmetic of the cosmetic of the Invention The present invention is characterized by containing a powder before a listen粧料. As the cosmetic of the present invention, a solid powder cosmetic is preferable. The solid powder cosmetic referred to in the present invention is obtained by coating powder with an oil / fat component of 30% by mass or less as desired, and molding the solid into a solid, and suitable examples of the molding means include pressure molding. it can. In the cosmetic of the present invention, the cosmetic powder as the essential component may contain only one species or a combination of two or more species. The content of the powder for cosmetics of the present invention, which is an essential component in the cosmetic of the present invention, is not particularly limited as long as the effect of the powder as a base powder in the cosmetic is manifested. For example, the total amount is preferably 1 to 60% by mass and more preferably 10 to 40% by mass with respect to the total amount of the cosmetic. In this amount range, there is an effect of covering the skin and giving gloss as the base powder.
