Description

  The present invention relates to an oil-in-water makeup cosmetic.

  Oil-in-water emulsified cosmetics are applied to makeup cosmetics such as foundations because they have a fresh and smooth feeling of use. However, the oil-in-water emulsified cosmetics have the drawback that the water repellency and the durability of the coating film are not sufficient.

In addition, conventionally, a hydrophobic powder is blended in cosmetics in order to give a smooth and slippery feel or to improve water resistance and makeup feeling. However, it is difficult to add the hydrophobic powder to the oil-in-water composition, and there is a problem that even when added, the powder aggregates and settles over time. In addition, cosmetics formulated with powder may cause a white residue when applied to the skin, which may significantly impair the appearance. In order to disperse hydrophobic powder more stably, use of a combination of specific polymer compounds has been studied (for example, Patent Document 1 and Patent Document 2).
However, these cosmetics are not satisfactory in terms of the wetness at the time of application, the dry feeling after drying, and the durability of the cosmetic coating film.

  The use of porous powders has been studied in order to give a smooth and slippery feel or improve makeup feeling (for example, Patent Document 3, Patent Document 4, Non-Patent Document 1). However, these cosmetics have not been sufficiently refreshed and not soggy at the time of application.

  On the other hand, various polymer thickeners are used in order to obtain cosmetics having excellent stability, and those that cause a change in feel when used are also known (Patent Documents 5 and 6). The gel cosmetic of Patent Document 5 is liquefied smoothly at the time of use, and the external preparation for skin of Patent Document 6 is used for a cue for completion of a massage action or the like due to a change in feeling during use. It did not change suddenly from freshness of time to a smooth feeling after drying.

  The problem of the present invention is that it has a good coating feel that is fresh and not greasy, and when dry it gives an instantly smooth feel, and the change from freshness to smoothness is instantaneous and yet repellent. An object of the present invention is to provide an oil-in-water makeup cosmetic that is excellent in aqueousness, makeup coating film persistence, excess sebum absorption and stability.

  When the present inventors use a specific acrylic acid-based crosspolymer in combination with a hydrophobized porous spherical silica, the present invention has a good coating feel that is fresh and not wet, and when dry, it feels instantly smooth. The change from freshness to smoothness is instantaneous, and an oil-in-water makeup cosmetic with excellent water repellency, makeup coating film persistence, excess sebum absorption and stability is obtained.
