[0015] [definition]

[0016] As used herein, "polymer" refers to a compound corresponding to the repetition of one or more units derived from compounds known as monomers. The unit or units are repeated at least 2 times, preferably at least 3 times.

[0017] As used in this specification, "hair" mainly refers to head hair.

[0018] As used herein, "hydrophobicity" means that the solubility of a substance in water at 25°C is less than 1% by mass.

[0019] As used herein, “film formation” means that a film remains on a substrate to which the composition is applied.

[0020] As used in this specification, "volatile" means having a boiling point of 260° C. or lower under normal pressure.

[0021] [Cosmetic composition]

[0022] The cosmetic composition of the present invention contains:

[0023] (A) an organic silicone film-forming agent; and

[0024] (B) an organopolysiloxane other than the component (A) having a polyalkylene oxide moiety and a cationic group,

[0025] The water content is 50% by mass or less.

[0026] The cosmetic composition of the present invention has the above-mentioned structure, and when applied to keratin substances such as skin or hair in a dry state, especially when used without rinsing with water, it can provide a smooth touch in the dry state and when rinsing, and the durability of these effects after washing is also excellent. In addition, if the cosmetic composition is used as a hair dye composition, it can provide the above-mentioned effects to hair, and there is less fading due to shampooing, and the color durability is also good.

[0027] The conditioning compositions described in Patent Documents 1 and 2 describe that the functionalized silicone polymer adheres to the hair durably, but there is a problem that the functionalized silicone polymer has a strong stickiness and it is difficult to obtain a good touch.

[0028] Furthermore, these care compositions are supposed to be applied to hair or fibers and then washed with water, i.e., rinsed. Therefore, when the care compositions are used after bathing and dried directly without rinsing with water, they feel more sticky and are not durable for practical use.

[0029] The present invention aims to provide a cosmetic composition which can provide a smooth touch in the dry state and when rinsed even when applied to keratin substances such as skin or hair in a dry state, especially when used without rinsing with water, and has excellent durability of these effects after rinsing.

[0030] The inventors of the present invention have found that the following cosmetic composition can solve the above-mentioned problems, thereby completing the present invention. The cosmetic composition comprises: an organic silicone film-forming agent; and an organic polysiloxane other than component (A) having a polyalkylene oxide moiety and a cationic group, wherein the water content is not more than a predetermined amount.

[0031] According to the present invention, a cosmetic composition can be provided, which can provide a smooth touch in a dry state and when rinsed, especially when not rinsed with water, even if applied to keratin substances such as skin or hair in a dry state, and the durability of these effects after washing is excellent. In addition, if the cosmetic composition is used as a hair dye composition, the above-mentioned effects can be imparted to hair, and there is less fading due to shampooing, and the color durability is also good.

[0032] The reason why the cosmetic composition of the present invention exhibits the above-mentioned effects has not yet been determined, but is presumed to be as follows.

[0033] A hydrophobic film can be formed by applying the cosmetic composition of the present invention containing the component (A) and the component (B) to the surface of a keratin substance.

[0034] Since component (B) has a polyalkylene oxide moiety and a cationic group, it is believed that it has a high adsorption property to keratin substances such as skin and hair, and is concentrated on the keratin substance side, so that the formed film adheres firmly to the surface of the keratin substance, thereby exerting an effect of preventing the film from peeling off.

[0035] On the other hand, component (A) is a hydrophobic film-forming agent, and it is believed that it maintains the strength and durability of the entire film formed, and when used together with component (B), it has excellent adhesion to keratin substances, good tracking properties to shape changes or movements of keratin substances, and also exerts an effect of imparting a smooth touch. In addition, when the functional powder described later is added to the cosmetic composition, it is believed that the functional powder is retained in the film, and various functions and their durability can be improved.

[0036] Furthermore, by setting the water content in the cosmetic composition to 50% by mass or less, precipitation does not occur over time, the drying speed is excellent, and a smooth touch feeling can be imparted even when the cosmetic composition is used after bathing without rinsing with water.

[0037] Therefore, for example, when the cosmetic composition is a hair cosmetic composition, when it is applied to dry hair after bathing and used without rinsing with water, it is believed that a smooth touch can be imparted even in the dry state and when rinsing, and the persistence of these effects can be obtained even after rinsing. In addition, when the cosmetic composition is a hair dye composition such as a temporary hair dye composition or a semi-permanent hair dye composition, it is believed that the above-mentioned effects can be imparted to the hair through the synergistic effect of component (A) and component (B), and the color discoloration caused by shampooing is reduced, and the color persistence can also be improved.

[0038] It should be noted that the mechanism of action of the present invention is not limited to the above content.

[0039] Hereinafter, each component contained in the cosmetic composition of the present invention will be described.
