Description

  The present invention relates to an emulsified hair composition, which is an emulsified composition and is used in a hair styling agent for shaping hair.

  In order to prepare hair, hair conditioner compositions having various properties such as liquid, gel, cream and solid are known. Conventionally, in a hairdressing composition, a film-forming polymer or a solid oil at room temperature is often used in order to exert the hairstyling power that is its main function (for example, Patent Document 1 and Patent Document 2).

  However, in a hairdressing composition using a film-forming polymer, a film is formed on the surface of the hair after styling due to the film-forming polymer. For this reason, when a film-forming polymer is blended as a main hair styling component, the initial hair styling power immediately after hair styling becomes high, while the hair after hair styling has problems such as no moist feeling, itching and poor touch. In addition, hair styling compositions using hydrocarbon oils, waxes and fats that are solid at room temperature have problems such as poor hair styling composition spreading during hair styling and hair stickiness after hair styling.

For example, the emulsified hair styling composition of the present invention can be produced by mixing the above-mentioned components and emulsifying by a phase inversion emulsification method using a homomixer. Moreover, mixing and emulsification may be performed separately or simultaneously. More specifically, for example, the heated mixture of the component (B) and the component (D) was added to the heated mixture of the component (A) and the component (C) while stirring with a homomixer, and then cooled to obtain. It can manufacture by adding a component (E) to an emulsion.

  The dosage form of the emulsified hairdressing composition of the present invention is not particularly limited, and examples thereof include emulsions and creams. Among these, an emulsion is preferable. The emulsified hairdressing composition of the present invention is an emulsified composition. By being an emulsified composition, a fresh touch can be imparted at the time of application.

  The viscosity at 25 ° C. of the emulsified hairdressing composition of the present invention is preferably 2000 to 30000 mPa · s, more preferably 4000 to 15000 mPa · s, from the viewpoints of applicability and non-stickiness. The above viscosity was measured using a viscometer, No. 4 rotor or no. The measurement is performed under the conditions of a rotation speed of 12 rpm and a rotation time of 1 minute using 3 rotors. A TV-22 type viscometer manufactured by Toki Sangyo Co., Ltd. can be used as the viscometer.

The emulsified hair styling composition of the present invention is characterized in that the component (B) is used as a main hair styling component in an emulsifier type. Since it is used as a main hair styling component, the emulsified hair styling composition of the present invention contains a relatively large amount of the component (B). Since the component (B) has a viscous property, the hair is tightly gathered and exhibits high hair styling power. On the other hand, since it does not solidify like a film-forming polymer and does not become hard after coating, there is no itchiness after hair styling as in the case of using a film-forming polymer, and the touch of hair after styling becomes good. In addition, the component (B) has good stretchability during hair styling, excellent coatability, and less stickiness after hair styling compared to solid hair styling components.
Furthermore, since component (B) has relatively high hydrophilicity, it exists in the matrix phase (outer phase) in the emulsification system. For this reason, the emulsified hair styling composition of the present invention exhibits a hair styling effect relatively quickly after application, so that it can be fastened (that is, it can quickly bundle hair bundles and form a desired wave), Usability is further improved. On the other hand, when a lipophilic hair styling component such as a liquid oil is used, the hair styling component is present in the particle phase (inner phase) in the emulsification system, so that the onset of the hair styling effect is slower than in the present invention. Become.
In addition, the emulsified hair styling composition of the present invention using component (B) is particularly excellent in storage stability.

Moreover, in the emulsified hairdressing composition of the present invention, by using a specific amount of the component (A), the stickiness after hairstyling caused by using a relatively large amount of the component (B) is suppressed, It is compatible with no stickiness. Ingredient (A) inhibits the hairs from sticking to each other, thereby imparting a certain degree of smoothness to the hair after styling and improving the touch. Moreover, the hair-styling power is further improved by a synergistic effect with the component (B).
Furthermore, when the component (E) is used, the effect of suppressing stickiness after styling is further improved. In addition, the hair styling power is further improved.

  The emulsified hair conditioner composition of the present invention is used as a hair conditioner for preparing hair. Among them, since it has high hair-styling ability and can adjust hair with a soft and smooth feel, it is preferably used as a hair-styling agent for middle hair, long hair, and permanent hair.
