Description

  The present invention relates to a solid cosmetic.

  In general, many skin care cosmetics are intended to be applied over a wide area such as the entire skin of the face and body, and those having good growth are preferred as cosmetics. Therefore, the present condition is that many cosmetics are creams or creams. However, recently, cosmetics for parts have also been demanded as a countermeasure for troubles with a part of the body, and the stick-like form disclosed in Patent Document 1 is intended for skin care by concentrating on a local part. There are solid cosmetics.

JP 2000-169360 A JP 2002-53420 A JP 2001-72529 A JP 2000-86445 A Japanese Patent Laid-Open No. 10-279433

In a solid cosmetic, water or a water-soluble solvent may be added from the viewpoint of adjusting the feeling of use. Moreover, in order to give a specific function, for example, whitening effect, to solid cosmetics, adding the plant extract containing water or a water-soluble solvent as an extraction solvent is examined.
However, it was found that when water or a water-soluble solvent was added to the solid cosmetic, droplets were generated on the surface of the solid cosmetic after a predetermined time. When water or a water-soluble solvent is mixed with a solid cosmetic based on a wax and an oil, stability at a high temperature is particularly poor, and a phenomenon that droplets are generated on the surface of the solid cosmetic (hereinafter referred to as sweating phenomenon) occurs. For this reason, it has been found that the beauty and usability of the solid cosmetic are impaired, and the whitening effect is reduced.

Patent Documents 2 to 4 are techniques for preventing perspiration of an oil agent in a solid cosmetic, but do not prevent perspiration of a solid cosmetic containing water or a water-soluble solvent.
On the other hand, Patent Document 5 is a technique for preventing perspiration of a solid cosmetic containing water or a water-soluble solvent. When the hygroscopicity of the solid cosmetic is increased, moisture in the outside air is taken into the cosmetic, This is based on the idea that the oil contained in the cosmetics is driven out by the incorporated moisture. In this document, by blending a hydrophobic powder with cosmetics, the opportunity for the humectant in the aqueous phase to come into contact with the outside air is reduced, moisture absorption is suppressed, and oil sweating is suppressed. However, with this method, it has been difficult to sufficiently suppress sweating.
As described above, conventionally, in the case of a solid cosmetic containing water or a water-soluble solvent, a study on a problem that a sweating phenomenon occurs has not been sufficiently performed.

According to the present invention,

(A) Oil agent liquid at 25 ° C. (B) Solid or semi-solid oil agent at 25 ° C. (C) Surfactant (D) Water and / or water-soluble solvent (E) A solid cosmetic containing an amphoteric compound Provided.

  According to this invention, in a solid cosmetic containing water or a water-soluble solvent, it is possible to suppress the occurrence of a sweating phenomenon that occurs on the surface of the solid cosmetic, and to maintain the aesthetics and feeling of use of the desired solid cosmetic. Cosmetics can be provided.

These powders can be used as powders that are inherently hydrophilic in surface, hydrophobic, or part or all of the powder surface that has been hydrophilized or hydrophobized. Among them, those having a hydrophilic surface or a hydrophilized powder are preferable because they are excellent in preventing sweating. The hydrophilization treatment can be performed using, for example, a water-soluble polymer such as polyacrylic acid, an inorganic compound such as silica or alumina, and a hydrophilization treatment agent such as a surfactant, and can be processed according to a normal method. . Moreover, it is preferable that the processing amount of the hydrophilization processing agent with respect to powder is 0.05-20 mass%, especially 2-10 mass%.

The solid cosmetic of the present invention as described above can be obtained by the following production method.
First, the component (G) is dispersed in the component (A) as necessary (mixture 1). Next, the component (B) is heated and melted in advance, and the mixture 1 of the component (A) and the component (G) is added to the melted component (B) (mixture 2). In the mixture 2 thus obtained, the mixture 3 of the component (C), the component (D), and the component (E) is dropped to obtain the mixture 4.
Next, the mixture 4 is poured into a mold at a predetermined temperature and cooled to obtain a solid cosmetic.

The characteristics of the solid cosmetics of the present invention as described above are that the solid cosmetics can be prevented from sweating during storage or use, the blending composition ratio does not change, the feeling of use is stable, and skin care ingredients such as whitening are added. When included, it is excellent in the stability of skin care effects such as whitening.
In general, solid cosmetics form a card house structure in which the component (B) holds the component (A) in the gaps between the structures formed by the component (B) forming plate-like wax crystals. . In order to retain the component (D) in such a card house structure, the surfactant of the component (C) may be added to improve the dispersibility of the component (D). It is thought that water and a water-soluble solvent can be held firmly by containing the amphoteric compound. Since the amphoteric compound has a cation and an anion group, it is considered that the amphoteric compound is easily hydrated and has a high effect of retaining water and the like. As a result, it is considered that the stability is drastically improved and so-called perspiration over time can be prevented.
In particular, when the component (E) contains an amino acid or an amino acid derivative, particularly trimethylglycine, it is considered that sweating can be more reliably prevented as a solid moisturizing agent with high water retention.
By preventing sweating, the composition over time does not change, the feeling of use and beauty do not change forever, and if skin care ingredients such as whitening are included, continue to use without changing the skin care effect such as whitening Can do.
In the present invention, the card house structure means a structure in which cards of playing cards are overlapped. These structures can be confirmed with a scanning electron microscope.

  It should be noted that the present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.
