Description

  The present invention relates to an oil-in-water type bubble-containing cosmetic in which bubbles are stably dispersed inside the cosmetic, and more specifically, excellent in stability of bubbles, lightness when picked up and applied to the skin The present invention relates to an oil-in-water type foam-containing cosmetic having a novel touch that has not been conventionally used, and a method for producing the same.

  Since preparations containing bubbles have a soft texture compared to preparations containing no bubbles, development of cosmetics using such preparations is underway. As a cosmetic containing such bubbles (hereinafter sometimes abbreviated as “bubble containing cosmetic”), a whipped cosmetic prepared by blending a specific oil agent and overrunning the gas (Patent Document 1) And a gel-like pack material that has been foamed in the presence of a surfactant (Patent Document 2), a cosmetic composition that stably blends bubbles of less than 20μ (Patent Document 3), and cosmetics in which the bubbles are stabilized by native gellan gum (Patent Document 4), whipped O / W emulsified cosmetics (Patent Document 5) and the like that have been bubbled in the presence of a higher fatty acid soap have been proposed.

  However, among the conventional foam-containing cosmetics that do not contain an oil agent, slipping is good due to the smoothness of the foam during application, but as the water gradually evaporates, the smoothness does not last and the slipping is poor. There was a drawback that the skin was not moistened after application.

  On the other hand, when the oil agent is blended, the above-mentioned disadvantage does not occur, but there is a problem that the gas-liquid interface is broken due to a decrease in surface tension or the like, and it becomes difficult to form bubbles.

  Emulsions are known as a means of blending oils in cosmetics, but water-in-oil whipped cosmetics blended with a high melting point wax and whipped make the feel heavy during use, causing bubbles. Even if it contains, there is a problem that it is difficult to reflect the characteristics in the feeling of use, and the characteristics are not exhibited even though it contains bubbles. Furthermore, giving priority to the feeling and feeling of use, and reducing the blending amount of the high melting point wax, the stability of the foam in a high temperature range of 40 ° C. or higher is lowered. It was difficult.

  In addition, in the whipped O / W emulsified cosmetics foamed in the presence of a higher fatty acid soap, it is unclear whether the texture will be fine and it is difficult to obtain the softness of the skin when applied to the skin. .

  Furthermore, as the foam-containing cosmetics that are actually commercialized, there are many known ones that have a mechanism for entraining bubbles in liquid cosmetics during use, such as aerosols.

Furthermore, in Comparative Example 5 in which component (B) was replaced with component (A), the system became harder than Comparative Example 2 and was very poor and inferior. As for bubble removal, since the bubble inclusion rate was lower than that immediately after production, no change was observed. Furthermore, instead of component (D), Comparative Example 6 containing a nonionic surfactant was the same as Comparative Example 3 because the dispersion of bubbles was not good.
