Description

  The present invention relates to makeup cosmetics such as foundation, blusher, lipstick, eyeliner, eye shadow, mascara, nail polish, and more specifically, the amount necessary for use can be easily taken. ) And good adhesion to the skin (adhesiveness), can be finished finely by suppressing color unevenness, color floating, color separation, etc. In addition to preventing rough skin, it also relates to a makeup cosmetic having a rough skin improving effect and a smoothing effect.

Usually, makeup cosmetics such as foundation, blusher, lipstick, eyeliner, and eye shadow are oily ingredients such as fats, waxes, hydrocarbons, higher alcohols, powders and coloring agents, and other ingredients as necessary (solvents, emulsifiers). , Antioxidants, plasticizers, etc.). The makeup cosmetic contains an inorganic pigment having a covering power on the skin, such as titanium dioxide, as one of these components. However, since these inorganic pigments are too adherent to the skin and the frictional resistance between the pigment particles and the skin is increased, there is a problem that the spread (extensibility) is deteriorated.
Then, makeup cosmetics that try to overcome the above-mentioned drawbacks by blending spherical titanium dioxide have been reported (Patent Document 1). However, this cosmetic has insufficient adhesion to the skin (adhesiveness), tends to cause makeup collapse over time, and may have poor makeup lasting (sustainability).

  In addition, make-up cosmetics are made of polyethylene, polyester, polystyrene, polymethyl methacrylate, cellulose, nylon, etc. in order to improve spreading (extension) by reducing sliding and to give a good feel to the skin. Resin powders may be blended, but since these resin powders have a low refractive index, the covering power to the skin is weak, and when used in combination with a pigment having a high refractive index and a strong covering power, it causes streaks. There was a problem that color unevenness, color floating, and color separation occurred. In order to overcome this problem, Patent Document 2 discloses a makeup cosmetic containing a resin powder whose surface is coated with an inorganic powder. However, this cosmetic also has a weak point in terms of adhesion (adhesion) to the skin, and over time, makeup collapse tends to occur, and makeup persistence (durability) may deteriorate.

  On the other hand, as cosmetics with improved makeup feeling (sustainability), for example, Patent Document 3 discloses makeup cosmetics containing boron nitride powder, and Patent Document 4 describes the surface with DNA (deoxyribonucleic acid). A makeup cosmetic comprising a coated pigment is disclosed. However, these cosmetics do not have sufficient adhesion to the skin (adhesiveness) and spread (extensibility), and may not be able to finish cleanly. Furthermore, Patent Document 5 discloses a water-in-oil solid emulsion makeup cosmetic comprising a specific alkylene oxide derivative (a block polymer of ethylene oxide or propylene oxide and an alkylene oxide having 6 to 40 carbon atoms). Yes. However, although this cosmetic has good slipperiness, it does not have sufficient adhesion to the skin (adhesiveness) and tends to cause makeup collapse over time.

  In addition, makeup cosmetics are cosmetics for hiding the skin with “makeup” and making it look beautiful. Due to its nature, the cosmetics are highly occlusive to the skin and often cause problems such as rough skin by preventing skin respiration. ing. Therefore, unlike skin care products, it is not usually expected that makeup cosmetics will have an effect of preventing rough skin. On the other hand, Patent Document 6 proposes a makeup cosmetic that imparts a rough skin prevention effect by blending a specific polyalkylene glycol derivative. However, even though the makeup cosmetics can suppress the rough skin caused by the use, it is not expected to have positive effects such as improving the rough skin and improving the texture of the skin. could not.

Japanese Patent Laid-Open No. 61-118311 JP 61-194010 A JP-A-7-145042 JP-A-8-198728 JP 2004-339217 A JP 2006-225324 A

  The problem to be solved by the present invention is that the required amount can be easily taken at the time of use, the spread (extensibility) and the adhesion to the skin (adhesion) are good, and the color unevenness, color floating, color separation, etc. Makeup makeup that can be finished beautifully by suppressing it, making makeup lasting for a long time (sustainability) by suppressing breakup of makeup, preventing rough skin, and improving skin roughness and improving skin condition. Is to provide a fee.

  As a result of repeated studies to solve the above-mentioned problems, a target makeup cosmetic was obtained by combining a specific polyalkylene glycol derivative and a color pigment in a specific ratio. That is, the present invention is as follows.
