Description

  The present invention is an oil-in-water emulsified composition that stretches lightly on the skin, gives a fresh feel, has a moist feeling after coating, has excellent water resistance, has low secondary adhesion, and has excellent temporal stability. The present invention relates to a cosmetic containing an oil-type emulsion composition. This invention claims priority based on Japanese Patent Application No. 2013-110556 for which it applied to Japan on May 27, 2013, and uses the content here.

  As conventional cosmetics, many emulsified cosmetics such as emulsions and creams have been put on the market as those that can replenish moisture and oil at the same time and keep the skin healthy.

  Typical emulsified cosmetics can be classified into oil-in-water emulsions in which oil is dispersed in water and water-in-oil emulsions in which water is dispersed in oil. Oil-in-water emulsions are often used in skin care cosmetics because they have good elongation during use and provide a light, refreshing and fresh feel. However, it has a problem that it is inferior in durability and water resistance of moist feeling. On the other hand, water-in-oil emulsions are easy to obtain a moist feeling and water resistance, but have a problem in feeling of use such as heavy elongation and stickiness.

  When blended with such oil-in-water emulsions and used as makeup cosmetics such as foundations, eye colors, and cheek colors, it is expected to have effects such as moisturizing effect and improvement of skin condition compared to solid ones. You can also. However, since a hydrophilic surfactant is required to disperse the oil component in the aqueous phase, there is a problem that the water resistance is poor and the cosmetic is easily removed by sweat or the like and the makeup is lost. . Therefore, especially in the case of makeup cosmetics, the surface of the pigment to be blended has been hydrophobized to improve water resistance, but it is difficult to blend these with water in a stable manner, and the pigment aggregates. Is often caused.

  In addition, after using cosmetics, if you operate a PC or mobile phone with a finger with cosmetic ingredients such as oil or pigment, the keys and screens touched by the finger will be soiled. There is also. There is also a problem with secondary adhesion such as when the color components of the cosmetics are transferred to the clothes when touched.

It has been reported that the oil-in-water emulsified cosmetic produced by the method of Patent Document 3 is excellent in elongation, water resistance and moisture retention and is easy to wash.

  Patent Document 4 discloses an oil-in-water emulsion emulsion cosmetic containing a specific surfactant, a fatty acid, and a basic amino acid salt. It has been reported that the oil-in-water emulsion type cosmetic of Patent Document 4 has good temperature stability, water resistance, water repellency, and stable pigment dispersion.

  Patent Document 5 discloses an oil-in-water solid cosmetic characterized by containing a water-soluble resin or a water-based emulsion resin. The oil-in-water solid cosmetic of Patent Document 5 is reported to be excellent in a refreshing feeling, a moist feeling, a freshness, water resistance, and an action of suppressing the evaporation of product moisture.

  Patent Document 6 discloses an oil-in-water emulsion composition having an HLB of less than 7 and a liquid surfactant at room temperature, and an HLB of 7 or more and a liquid surfactant at room temperature and a hydrophobic powder. Things are disclosed. It has been reported that the oil-in-water emulsion composition of Patent Document 6 has good elongation, freshness, water resistance, and long-lasting makeup.

  As mentioned above, various methods have been taken to achieve both the refreshing feel and water resistance of the oil-in-water emulsion composition, but at the same time, it maintains a moist feeling, prevents secondary adhesion, and stabilizes over time. No one has been found that satisfies everything about sex.

  From the above background, oil-in-water emulsified composition that stretches lightly on the skin, gives a fresh feel, has a moist feeling after coating, has excellent water resistance, low secondary adhesion, and excellent stability over time And cosmetics containing the oil-in-water emulsion composition are desired.
