Description

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

In the past, various moisturizing ingredients and oils were blended to protect the skin from the external environment such as dryness and physical irritation, to soften the skin by moisturizing it, to maintain a youthful appearance, and to make the skin look beautiful. Skin cosmetics are being considered.
For example, in Patent Document 1, an oil agent that is liquid at 25°C, an oil agent that is solid or semi-solid at 25°C, a higher alcohol, and a surfactant are contained, and the number average particle size of the emulsified particles is within a specific range.
