Description

[Technical field]

[0001] The present invention relates to an aerosol type hair cosmetic composition which imparts natural shine and a smooth feel and has an antistatic effect. [Background technology]

[0002] In recent years, hairstyles that give hair a natural shine and a smooth feel as if it was born have become mainstream. Preparations for achieving such hairstyles include hair oils, hair balms, greases, hair gels, hair sprays, etc.

[0003] Among them, hair oil, which was often used for hair care in the past, is now often used as a styling product. However, many hair oils that give a light finish with a natural shine and smooth feel tend to make hair electrostatically charged, and there is a problem that the more hair oil is applied, the more the hair spreads, especially when it is dry. In addition, since it is applied to the hair after spreading it on the hands, it is also troublesome to have to wash your hands after use.

[0004] In recent years, therefore, there has been a demand for aerosol-type hair cosmetics that provide a natural shine, a smooth finish, and have an antistatic effect.

[0005] Patent Document 1 proposes a hair styling composition that provides hair with setting power, no stickiness, no stiffness, and shine, while Patent Document 2 proposes a hair cosmetic that has an antistatic effect and leaves a smooth finish. [Prior art documents] [Patent documents]

[0013] From the viewpoint of natural luster and silky feel, the present invention provides a composition having a kinetic viscosity of 2 to 10 mm at 25° C. 2 Contains methylpolysiloxane / s.

[0014] The component (A) used in the present invention is not particularly limited, but examples thereof include methylpolysiloxane (2 mm 2 / s) [KF-96L-2CS (manufactured by Shin-Etsu Chemical Co., Ltd.)], methylpolysiloxane (5 mm 2 / s) [KF-96A-5CS (manufactured by Shin-Etsu Chemical Co., Ltd.)], methylpolysiloxane (10 mm 2 / s) [KF-96A-10CS (manufactured by Shin-Etsu Chemical Co., Ltd.)], etc.

[0015] Among the components (A) used in the present invention, from the viewpoint of improving the smooth feeling, a component having a kinetic viscosity at 25° C. of 2 to 5 mm 2 / s methylpolysiloxane is preferred.

[0016] From the viewpoint of natural shine, the present invention contains (B) one or more members selected from diphenylsiloxyphenyl trimethicone, phenyl trimethicone, and polyoxyethylene (10E.O.)·methylpolysiloxane copolymer.

[0017] The component (B) used in the present invention is not particularly limited, but examples thereof include diphenylsiloxyphenyl trimethicone [KF-56A (manufactured by Shin-Etsu Chemical Co., Ltd.)], phenyl trimethicone [DOWSIL SH 556 Fluid (manufactured by Dow-Toray Industries, Inc.)], polyoxyethylene (10E.O.)-methylpolysiloxane copolymer [KF-6017 (manufactured by Shin-Etsu Chemical Co., Ltd.)], and the like.

[0018] Of the components (B) used in the present invention, diphenylsiloxyphenyl trimethicone is preferred from the viewpoint of improving natural shine.

[0019] The mass ratio (B) / (A) of the (A) component and the (B) component in the aerosol concentrate used in the present invention is 0.05 to 0.64, preferably 0.07 to 0.5, and more preferably 0.1 to 0.29. If the mass ratio (B) / (A) is less than 0.05, natural shine cannot be obtained. If the mass ratio (B) / (A) is more than 0.64, natural shine and smooth feel cannot be obtained.

[0020] The present invention contains ethanol (C) from the viewpoint of smooth feeling.

[0021] The content of the component (C) in the aerosol concentrate used in the present invention is 0.5 to 50%, preferably 1 to 40%, and more preferably 4 to 30%. If the content of the component (C) in the aerosol concentrate is less than 0.5%, a smooth feel cannot be obtained. If the content of the component (C) in the aerosol concentrate is more than 50%, a natural shine cannot be obtained.

[0022] The present invention contains (D) stearyltrimethylammonium chloride from the viewpoint of antistatic effect.

[0023] The content of the component (D) in the aerosol concentrate used in the present invention is 0.1 to 1%, preferably 0.15 to 0.8%, and more preferably 0.2 to 0.6%. If the content of the component (D) in the aerosol concentrate is less than 0.1%, the antistatic effect cannot be obtained. If the content of the component (D) in the aerosol concentrate is more than 1%, the natural luster cannot be obtained.

[0024] The present invention contains (E) a propellant.

[0025] The (E) component used in the present invention is not particularly limited, but examples thereof include dimethyl ether (DME), isobutane, liquefied petroleum gas (LPG), nitrogen gas, etc. Among these, liquefied petroleum gas or dimethyl ether is preferred, and liquefied petroleum gas is more preferred.

[0026] The initial internal pressure of the component (E) used in the present invention at 20° C. is preferably in the range of 0.15 to 0.25 MPa. The initial internal pressure of the liquefied petroleum gas can be adjusted to any desired value by changing the composition of propane and butane, and can also be adjusted by combining the liquefied petroleum gas with the type of dimethyl ether, etc.

[0027] The mass ratio of the aerosol concentrate to the (E) component used in the present invention (aerosol concentrate / (E) propellant) is 30 / 70 to 3 / 97, preferably 25 / 75 to 5 / 95, more preferably 20 / 80 to 10 / 90. In the mass ratio of the aerosol concentrate to the (E) component in percentage (aerosol concentrate / (E) propellant), if the ratio of the (E) component is less than 70, the discharge amount of the aerosol concentrate increases, and natural gloss and smooth feeling cannot be obtained. In addition, it becomes difficult to apply uniformly. In the mass ratio of the aerosol concentrate to the (E) component in percentage (aerosol concentrate / (E) propellant), if the ratio of the (E) component is more than 97, natural gloss cannot be obtained.

[0028] Many of the prior art aerosol-type hair cosmetics have a high ratio of ethanol in the aerosol concentrate and a low ratio of the (E) component. In such aerosol-type hair cosmetics, a large amount of the aerosol concentrate is discharged at once, which can cause the hair to feel cold and squeaky when discharged. In the present invention, the mass ratio of the aerosol concentrate to the (E) component is higher than that of the aerosol concentrate. This makes it possible to achieve a natural shine and smooth feel that has never been seen before, and also makes it easy to use without getting your hands dirty.

[0029] In addition to the above-mentioned components, the aerosol-type hair cosmetic composition of the present invention can contain, as long as the effects of the present invention are not impaired, ingredients commonly used in cosmetics, such as film-forming resins, surfactants, silicone oils other than components (A) and (B), oily ingredients other than silicone oils, alcohols other than component (C), pH adjusters, sequestering agents, UV absorbers, fragrances, antioxidants, preservatives, moisturizers, cooling agents, thickeners, vitamins, plant extracts, protein hydrolysates, colorants, etc., and the aerosol-type hair cosmetic composition of the present invention may contain one or more of these ingredients.

[0030] The appearance of the concentrate of the aerosol type hair cosmetic composition of the present invention is not particularly limited as long as it can be sprayed without clogging, and may be transparent, opaque, colored, pearlescent, etc.

[0031] The internal pressure of the aerosol type hair cosmetic composition at 25° C. is not particularly limited, but is preferably 0.2 to 0.4 MPa. EXAMPLES
