On the other hand, when the content is 0.5% by mass or less, the stability of the cleansing cosmetic of the present invention is further improved. Content of the said component (F) is a total amount of content of all the components (F) in the cleansing cosmetics of this invention.

  The cleansing cosmetic of the present invention substantially contains an oil selected from the group consisting of fats, waxes, silicone oils, hydrocarbons, and ester oils from the viewpoint of improving the feeling of use by suppressing stickiness after use. Preferably not. Specifically, the content of the oil agent in the cleansing cosmetic of the present invention is preferably 5.0% by mass or less (0 to 5.0% by mass) with respect to 100% by mass of the cleansing cosmetic of the present invention. More preferably, it is 0-1.0 mass%. That is, the cleansing cosmetic composition of the present invention contains or does not contain the oil agent, and the content of the oil agent is preferably 0 to 5.0% by mass, more preferably 0 to 1.0% by mass.

  The cleansing cosmetic of the present invention is a cosmetic having a makeup removing function (cleansing function), that is, a makeup removing agent. The cleansing cosmetic of the present invention is preferably a skin cosmetic used for the skin, more preferably a facial skin cosmetic. In the present specification, “cosmetics” is not limited to “cosmetics” in the so-called Pharmaceuticals and Medical Devices Act (former Pharmaceutical Affairs Law) in Japan, for example, cosmetics, quasi drugs, pharmaceuticals, Any of miscellaneous goods may be used.

  The cleansing cosmetic composition of the present invention can be produced by a conventional method. For example, the above-mentioned constituent components are mixed and a known method, specifically, a method of stirring with a homomixer or the like can be mentioned.

The cleansing cosmetic of the present invention is an aqueous cosmetic having a high water content. For this reason, there is no stickiness due to the remaining oil agent after use, which is preferable. Further, it is preferable because washing and wiping after use can be easily performed.
The cleansing cosmetic composition of the present invention contains a nonionic surfactant (component (C)) as a main surfactant. For this reason, it is highly safe and can be preferably used as a cleansing cosmetic of a type that is used without being washed away after use (for example, a cleansing cosmetic for wiping off), and is excellent in versatility.
Furthermore, by blending glycerin, diglycerin, polyethylene glycol, sorbitol, maltitol (component (D)), the moisturizing feeling of the skin after removing makeup with cleansing cosmetics is enhanced, so the feeling of use of cleansing cosmetics is increased. improves. Moreover, the antiseptic property of cleansing cosmetics improves by mix | blending ethanol (component (D)). These characteristics are particularly preferable in the case of cleansing cosmetics of the type used without being washed away (in particular, cleansing cosmetics for wiping off).
On the other hand, in the case of an aqueous cleansing cosmetic comprising a nonionic surfactant as a main surfactant, when the above component (D) is added, the hydrogen bonding force is lowered and the cloud point of the nonionic surfactant is lowered. However, when stored for a long time (especially when stored in a high temperature environment of 40 ° C. or higher, for example), there is a problem that the stability of the cleansing cosmetic is lowered, such as precipitation of the surfactant. .
In the present invention, by blending a specific amount of the component (B) which is a polyether compound having a specific structure, it is presumed to be due to the action as a dissolution aid by ethylene oxide and propylene oxide. The stability of cleansing cosmetics containing (C) and component (D) was dramatically improved. Thereby, the cleansing cosmetic composition of the present invention is excellent in make-up removal effect and safety by using the component (C) and the component (D) in a sufficient blending amount, and further has a feeling of use and / or antiseptic properties. In addition, the component (B) is also excellent in stability. In addition, since the moist feel of the skin after makeup removal is further improved by the component (B), the cleansing cosmetic of the present invention is particularly excellent in use feeling.

  Furthermore, it is preferable to use an anionic surfactant (component (E)) in addition to the component (B) because the stability of the cleansing cosmetic of the present invention is further improved.

  In addition, by blending the water-soluble polymer compound (component (F)), especially when the cleansing cosmetic of the present invention is soaked into a non-woven fabric and the like to wipe off and remove the makeup, the friction feeling between the skin and the non-woven fabric etc. Therefore, the feeling of use is further improved. In a cleansing cosmetic that does not contain a general component (B), when the component (F) is added, the stability of the system tends to be reduced. In the present invention, however, the component (B) (preferably, the further component By blending (E)), excellent stability can be achieved even when component (F) is blended.

  For this reason, the cleansing cosmetic composition of the present invention is excellent in versatility because it can be preferably used for both a method of washing after removing makeup and a method of washing (for example, wiping off) after removing makeup.

  The usage method of the cleansing cosmetic composition of the present invention is not particularly limited, and examples thereof include known usage methods of cleansing cosmetic products. Specifically, for example, the method of removing the cleansing cosmetic composition of the present invention by directly applying it to the makeup on the skin; and soaking the cleansing cosmetic composition of the present invention in a cloth such as cotton (woven fabric, non-woven fabric, etc.) And a method of wiping the makeup on the skin with the cloth. Furthermore, a method of preparing a sheet product in which the cleansing cosmetic of the present invention has been impregnated into a sheet base material in advance and wiping off the makeup with the sheet product is also included. The skin after removing the makeup may or may not be washed away. That is, the cleansing cosmetic of the present invention may be a cleansing cosmetic that is washed away, or may be a cleansing cosmetic that is not washed away. Among them, the cleansing cosmetic of the present invention is preferably a cleansing cosmetic (in particular, a cleansing cosmetic for wiping) that is used without being washed away from the viewpoint of the above characteristics.
