Description

The present invention relates to a cosmetic mist, and particularly to a cosmetic mist that is excellent in skin gloss, pearl agent dispersibility, pearl agent retention on the skin, and non-sticky skin.

How to use lotion: Take an appropriate amount of lotion in your hand and spread it over the entire face, soak a cotton ball with an appropriate amount of lotion and spread it over the entire face, or fill a container such as an atomizer or dispenser with lotion to create a mist. There are methods such as pushing an appropriate amount onto the entire face as a cosmetic. Among these, mist-type cosmetics that can be easily and uniformly applied over a wide area are recognized in the market and are in constant demand.

In particular, mist-type cosmetics used on the face are often used after applying makeup cosmetics, so in addition to the fineness of the mist and the feeling of use when applied to the skin, it is possible to add shine to the skin. It has been demanded.

Generally, it is known that a method of imparting luster to the skin is to incorporate high brightness particles such as pearlescent agents. Examples of formulations containing high-gloss particles include liquid cosmetics containing high-gloss particles, film-forming resins, anionic polymers, and water (Patent Document 1), and mist cosmetics containing gellan gum and alkyl acrylate methacrylates. Cosmetics containing polymers (Patent Document 2) have been disclosed, but while the inclusion of a large amount of pearlescent agent increases the glossiness of the skin, it also causes problems such as mist clogging and mist clogging due to poor dispersibility of the pearlescent agent. There was a problem with the retention of the pearl agent on the skin.

Polyoxyethylene sorbitan monostearate is preferred.

The content of the component (B) used in the present invention is preferably 0.1 to 2% by mass, more preferably 0.5 to 1.5% by mass. When the content of the component (B) is less than 0.1% by mass, the dispersibility of the pearl agent may deteriorate. When the content of the component (B) exceeds 2% by mass, stickiness may occur.

The present invention contains (C) a water-soluble film forming agent from the viewpoint of retention of the pearl agent on the skin and non-stickiness of the skin.
