Description

Scalp composition, scalp cosmetic preparation, and method for applying scalp composition
Technical Field
The present invention relates to a composition for scalp to be applied to scalp. The present invention also relates to a scalp cosmetic using the scalp composition, and a method for applying the scalp composition.
Background
The human scalp is exposed to ultraviolet light, or is irritated by shampooing, or is heat irritated by drying of a hair dryer. Among them, drying by a blower easily evaporates water from the scalp. Thus, the scalp of a person is damaged every day due to various external factors in daily life. The scalp is drier than the skin of other parts such as the face. Therefore, the barrier function of the scalp is sometimes greatly reduced.
If the barrier function of the scalp is decreased, the scalp is hardened and developed, and the scalp is easily affected with head dirt, redness, eczema, itching, and the like. In addition, such scalp problems may cause a reduction in the tension and elasticity of the hair, thereby increasing the thinning of the hair.
Therefore, for the scalp, moisturizing care for imparting moisturization is desired. However, the scalp has a large amount of sebum compared to the skin of other parts. Therefore, even when ordinary cosmetic water is applied to the scalp, it is difficult for the moisturizing component to sufficiently permeate, and it is difficult to sufficiently moisturize the scalp.
In addition, since hair is present on the scalp, it is also difficult to effectively apply a cosmetic liquid (scalp composition) to the scalp.
As described above, the cosmetic water (scalp composition) applied to the scalp has several problems, and studies are being made to solve the problems. The following patent documents 1 to 5 disclose compositions for scalp.
Patent document 1 below discloses a composition containing a humectant and adenosine.
Patent document 2 below discloses a composition containing a eucalyptus extract, a polyhydric alcohol, and at least one of a moisturizing agent and an anti-inflammatory agent.
Patent document 3 below discloses a composition containing an anti-inflammatory agent, a bactericide and polyethylene glycol.
Patent document 4 below discloses a composition containing an organic carboxylic acid or a salt thereof. The composition has a pH of 1 to 5 at 25 ℃ when diluted 20 times by weight with water.
Patent document 5 below discloses a composition containing acetylated hyaluronic acid or a salt thereof, and hydroxyethyl urea.

Detailed Description
The present invention will be described in detail below.
The scalp composition of the present invention is a scalp composition that is filled in a spray type trigger container or a spray type pump container and is discharged by a spray method.
In the present invention, both the optimum composition design and the optimum viscosity design are performed for the scalp composition to be applied to the scalp from the specific container by the spray method.
The scalp composition of the present invention comprises a diester of cyclohexanedicarboxylic acid with a polyoxyalkylene alkyl ether, ethanol, a polyol, and a thickener. The scalp composition of the present invention has a viscosity of 50 to 600 mPas at 25 ℃.
In the present specification, the diester of cyclohexanedicarboxylic acid and polyoxyalkylene alkyl ether may be referred to as "(a) a diester of cyclohexanedicarboxylic acid and polyoxyalkylene alkyl ether" or "component (a)". The above ethanol may be referred to as "(B) ethanol" or "component (B)". The above polyol may be referred to as "(C) polyol" or "component (C)". The thickener is sometimes referred to as a "(D) thickener" or "component (D)".
In the present invention, the scalp pack is applied to the scalp from the specific container by spraying, and therefore, the scalp pack can have improved penetration into the scalp, adhesion, drip resistance, detachability, and moisture retention properties.
That is, the scalp composition is easily penetrated into the scalp. The scalp composition is easily attached to the scalp and hair after application by a spray method, and easily maintains the attached state. The composition for scalp is difficult to drip from the scalp and hair after application by a spray method. The scalp composition can suppress stickiness on the scalp and hair after application by the spray method. The scalp composition can improve the moisture retention of the scalp after application.
When the scalp composition is applied to the scalp by a spray method, the scalp composition is usually applied to the hair. The scalp composition is preferably a scalp and hair composition. When the scalp composition is applied to the scalp, the scalp can be kept in a good condition, and the scalp composition adhering to the hair can also favorably affect the condition of the hair. In the present invention, since the scalp pack is provided with the above-mentioned structure, the tension and elasticity of the hair can be improved when the scalp pack is applied to the scalp from the specific container by spraying.
In the present invention, not only some of the scalp permeability, adhesion, drip resistance, detackability, and moisture retention properties can be improved, but also all of the properties can be improved. In addition, the present invention can also improve the tension and elasticity of hair. In the present invention, a composition of a combination of a composition and a viscosity range capable of satisfying all of these effects, not part of them, is found.
In addition, the scalp composition is applied to the hair from the specific container by spraying, so that the scalp composition can effectively improve the penetration and moisture retention to the scalp. In addition, it is considered that the scalp composition is reduced in adhesiveness and is likely to drip when applied by the spray method. In the present invention, the scalp composition is applied to the hair from the specific container by a spray method, but the adhesion and drip resistance of the scalp composition can be sufficiently improved. In addition, in the present invention, since the application method by the spray method is adopted, the permeability and moisture retention on the scalp can be effectively improved.

By adopting the above-mentioned specific composition and controlling the above-mentioned viscosity within the above-mentioned range, all the following effects can be improved in balance: improving effects of permeability, adhesiveness, dripping prevention, antisticking, moisture keeping, and hair tension and elasticity on scalp.
The viscosity is preferably 80mPa · s or more from the viewpoint of further improving the adhesion and preventing dripping. From the viewpoint of further preventing stickiness and the viewpoint of further suppressing ejection failure, the viscosity is preferably 500mPa · s or less.
The measurement of the viscosity η is not particularly limited, and for example, a B-type viscometer is used. As the measurement conditions, for example, the measurement was carried out using rotor No.2 at 25 ℃ and 30 rpm. As the type B viscometer, "TV-20" manufactured by Toyobo industries Co., Ltd can be used.
The scalp cosmetic of the present invention includes the scalp composition described above, and a spray-type trigger container or a spray-type pump container. The trigger container or the pump container is filled with the scalp composition.
In the present invention, the scalp composition may be applied not only to the scalp but also to both the scalp and the hair. In order to improve the penetration into the scalp and moisture retention and to achieve this at a high level, an ejection pattern based on an ejection method is used as the ejection pattern of the scalp composition. In general, compositions intended to be applied to the whole hair, such as compositions not intended to be applied to the scalp or hair styling agents, are sprayed in a spray form by a mist spray, and it is considered that a spray form is not generally employed.
In the method for applying the scalp composition of the present invention, the scalp cosmetic material is used to spray the scalp composition onto the scalp by a spray method.
In the discharge in the spray method, for example, the scalp composition is discharged in a linear shape. In the discharge in the spray method, the scalp composition easily passes through the hair to reach the scalp. In the discharge in the spray method, when the scalp composition is discharged 1 time in the horizontal direction, the discharge area (area surrounded by the outer periphery of the discharged hair composition) at a distance of 10cm from the discharge part is 9cm2The following. The ejection in the spray mode is different from the ejection in the spray mode. In the spray method, when the composition is sprayed 1 time in the horizontal direction, the spray area (area surrounded by the outer periphery of the sprayed hair composition) at a distance of 10cm from the spray part exceeds 100cm2. In the ejection in the spray method, the composition is applied over a wide area. In the spray pattern, the composition is difficult to pass through the hair to reach the scalp.
