Description

The present invention relates to aerosol type cosmetics.

In recent years, awareness of countermeasures against ultraviolet rays that may cause spots and wrinkles has increased, and sunscreen cosmetics are used throughout the year, not only in summer when the amount of ultraviolet rays is high. In the market, various types of sunscreen cosmetics such as milk type, gel type, aerosol type are developed. Among them, in the case of an aerosol type cosmetic spray, it is easy to apply to a wide range of the skin and hair, and can be easily applied to a part that is difficult to reach, and therefore, high usability is evaluated.

On the other hand, aerosol-type cosmetics generally have a problem in terms of function such as a thin makeup film and are easily twisted, and a problem in terms of feeling that a slimy feeling is remarkable when a large amount of an oil agent is added. Conventionally, a technique for improving water resistance by blending an organic silicone resin (for example, Patent Document 1) and a technique for improving makeup retention and water resistance by containing trimethylsiloxysilicic acid in a sunscreen cosmetic (for example, Patent Document 2) has been studied, but with these techniques, the sliminess of the film-forming agent becomes remarkable, and there is room for consideration in terms of the feel. Further, as a technique for suppressing a slimy feeling, a technique for suppressing stickiness by containing a powder having a number average particle size of 1 μm or more and 10 μm or less in a skin cosmetic containing a propellant (for example, Patent Document 3). Although it has been studied, it was not satisfactory in terms of function because the makeup film was easily twisted and the strength of the film was low although the slimy feeling could be suppressed.

Furthermore, aerosol type cosmetics are a special environment under pressure in which a liquid concentrate of a cosmetic and a liquefied gas or a compressed gas as a propellant coexist in a container, and therefore, aggregation and viscosity change are likely to occur. As a result, clogging occurs at the ejection port and the like, leading to a decrease in jettability and a problem of usability such as non-uniform jetting. Therefore, it is an important factor to maintain uniform dispersibility of the undiluted solution and the liquefied gas in the container, and the aerosol-type cosmetic material is always sprayed constantly to make the cosmetic film uniform and to protect the ultraviolet rays and The abrasion resistance function is improved.

Japanese Patent Laid-Open No. 1-75414 JP, 2008-8910, A JP, 2016-6029, A
