Description

The present invention relates to a cosmetic prop cleaning agent that removes stains on cosmetic props and has an excellent drying speed.

In recent years, various methods for applying foundations and the like have been proposed in make-up due to improvements in technology, and there are a wide variety of props such as coating tools to be used. Few such props are disposable and are usually expected to be used many times. However, with the technological development of cosmetics, the number of cosmetics having very good makeup retention is increasing, and it tends to be difficult to remove the cosmetics adhering to the props. Conjunctive use of an applicator with residual cosmetics not only poses a hygiene problem, but may also affect the make-up effect, and cleaning agents for cosmetic props have been developed so far. For example, a cosmetic sponge cleaning agent (Patent Document 1) containing a betaine-based amphoteric surfactant and a polyoxyethylene-based nonionic surfactant, which has excellent detergency and less damage to the sponge, and volatile. There has been a technique of a cleaning agent composition (Patent Document 2) containing hydrocarbons, silicones, vegetable oils and fats, ester oils and the like.

However, all of these cleaning agents contain water and a surfactant, and are techniques aimed at washing with water. In this case, it takes time to move the props to a water place to wash them or to dry them. For example, if you notice that the props are dirty when you try to make up, or if you do not have a water place nearby, such as when selling to customers at the store, or if you want to use it immediately after cleaning, it is not suitable for use. There is. Therefore, it has been desired to develop a cosmetic prop cleaning agent that can easily remove the cosmetic remaining on the prop without using water and can be used immediately after cleaning by drying quickly.

In view of such circumstances, the present inventor has focused on improving the drying rate by combining volatile hydrocarbon oil and volatile silicone as a result of diligent studies, and these may be abbreviated as 95% by mass (hereinafter abbreviated as%). The present invention has been completed by finding that the cosmetic prop cleaning agent contained above can easily remove stains on the cosmetic props, has a high drying speed, and can be reused quickly after cleaning.

That is, the present invention
Provided is a cosmetic prop cleaning agent containing the component (a) volatile hydrocarbon oil and the component (b) volatile silicone oil, and the total content of (a) and (b) is 95% or more. Is.

The cosmetic prop cleaning agent of the present invention can easily remove stains on cosmetic props, has a high drying speed, and can be reused quickly after cleaning.

Hereinafter, the configuration of the present invention will be described in detail.
The cosmetic prop cleaning agent of the present invention can be used for application tools such as sponges, puffs, brushes, brushes, and tips used for makeup, as well as after use of props such as massage rollers and caps used for skin care. It removes dirt.

The volatile silicone oil of the component (b) of the present invention is a liquid having a boiling point in the range of 60 to 260 ° C. at normal pressure. Although not particularly limited, those generally used for cosmetics are preferable in that they are used for props used on the skin. Specific examples thereof include low molecular weight dimethylpolysiloxane, methyltrimethicone, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane having a molecular weight of less than 100. Commercially available products include DC345 FLUID. , SH245 FLUID, SH344 FLUID (above, manufactured by Toray Dow Corning), KF-994, KF-995, TMF1.5 (above, manufactured by Shin-Etsu Chemical Co., Ltd.) and the like. These volatile silicone oils may be used alone or in combination of two or more. As the volatile silicone oil, one having a boiling point of less than 200 ° C. is preferable in terms of drying speed, and for example, methyltrimethicone is preferably used.

The content of the component (b) in the present invention is not particularly limited, but is preferably 5 to 50%, more preferably 5 to 30%, and even more preferably 10 to 20%. This range is more preferable in terms of stain removal and drying speed.
