Description

  The present invention relates to skin cosmetics.

Cosmetics containing various moisturizing ingredients and oils have been developed for the purpose of protecting the skin from the external environment such as drying and physical irritation and keeping the skin soft and moist by keeping it moist.
However, when trying to increase the moisturizing power by using a moisturizing component or an oil agent, it is necessary to increase the blending amount, which causes a problem in terms of feeling of use such as stickiness. Also, the sustainability of the effect is not enough.
On the other hand, high-polymerized silicone is known as a component for smoothing the skin, but if it is to be blended stably into cosmetics, the blending components such as surfactants may be limited, and the smoothness may be reduced. There are also issues regarding sustainability.
Heretofore, almost no cosmetics having both a moisturizing effect and a smooth feeling have been known.

  In addition, cosmetics having a lamella structure similar to intercellular lipids to obtain a moisturizing effect are known. In order to obtain a cosmetic product having a smooth touch with a moisturizing effect, further, a cosmetic product containing powder has been studied (for example, Patent Documents 1 and 2).
