Description

The present invention relates to an aerosol spray hair styling agent in which a hair styling composition and a propellant are filled in an aerosol container.

People often prefer hairstyles that are natural, refreshing, and unruly (hereinafter sometimes referred to as "natural-hair-like hairstyles"). However, in everyday life, this natural-hair-like hairstyle can become partially messed up. For example, wearing a hat or helmet, or pressing the back of the head against the headrest of a car or train for a long period of time, can cause the hair to become partially rubbed, disrupting the natural-hair-like hairstyle.

Generally, hair straightening sprays are known as hair styling products for straightening curls formed in hair (for example, Patent Documents 1 and 2 below). Hair straightening sprays are designed to spray a hair styling product composition contained in a trigger-type container with low force over a wide area to straighten curls formed over the entire head.

JP 2004-059485 A JP 2002-302422 A

Conventional hair straightening sprays spray the hair styling composition over a wide area with low force, making it difficult to straighten out partial curls in hair that have developed in daily life (curls that are different from curls that have developed during sleep). In addition, when a large amount of hair styling composition is sprayed with a hair straightening spray so that a large amount of the hair styling composition adheres to the curled area, the hair styling composition drips off the hair.

In addition, if you use conventional hair styling products to correct certain parts of your hair, you will not be able to maintain a natural hairstyle.

The object of the present invention is to provide an aerosol spray hair styling agent that can effectively attach the hair styling composition to desired locations, effectively straighten partial curls of hair acquired in daily life, and furthermore, maintain a natural-looking hairstyle even after straightening the curls.

The present invention provides an aerosol container, a hair styling composition, and a propellant, the hair styling composition and the propellant being filled in the aerosol container, the hair styling composition comprising the following components (A), (B), (C), (D), and (E), the content of the component (A) being 9.0% by mass or more and 33.0% by mass or less, the content of the component (B) being 0.08% by mass or more and 2.3% by mass or less, the content of the component (C) being 0.03% by mass or more and 1.1% by mass or less, and the content of the component (D) being 0.03% by mass or more and 1.1% by mass or less, in 100% by mass of the hair styling composition, and when the spray button of the aerosol container is pressed to spray the hair styling composition toward a wall surface from a position 15 cm from the wall surface for 1 second, the area of a region surrounded by an outer edge of the hair styling composition adhering to the wall surface is 20 cm The present invention provides an aerosol spray hair styling agent having a viscosity of ² or less.

Component (A): Ethanol Component (B): Nonionic surfactant Component (C): Powder Component (D): Amphiphilic ester Component (E): Water

The aerosol spray hair styling agent of the present invention allows the hair styling composition to be applied effectively to the desired area, making it possible to effectively straighten out partial curls in the hair that have developed in daily life, and furthermore, to maintain a hairstyle that gives the impression of natural hair even after straightening the curls.

In the aerosol spray hair styling agent, the hair styling agent composition can be discharged in the form of a mist from the aerosol container. The hair styling agent composition is a blend of the contents filled in the aerosol container in the aerosol spray hair styling agent, excluding the propellant.

The aerosol container has an ejection button. By pressing the ejection button, the filling material filled in the aerosol container can be ejected in a mist form from the aerosol container. The aerosol container is preferably an aerosol spray container. The aerosol spray container has a button-type actuator.

In the aerosol spray hair styling agent, when the spray button on the aerosol container is pressed to spray the hair styling agent composition toward the wall surface from a position 15 cm from the wall surface for 1 second, the area of the region surrounded by the outer edge of the hair styling agent composition adhering to the wall surface is 20 ^cm2 or less.

In this specification, a test in which the spray button on the aerosol container is pressed to spray the hair styling composition toward the wall from a position 15 cm away from the wall for 1 second is sometimes referred to as a "spray test."

Therefore, in the case of the aerosol spray hair styling agent, when the spray test is carried out, the area of the region surrounded by the outer edge of the hair styling agent composition attached to the wall surface is 20 ^cm2 or less. Therefore, the hair styling agent composition can be well attached to the desired location, and partial curls of hair acquired in daily life can be well corrected.

The injection test procedure is explained in detail below with reference to the drawings.

Figures 1(a) and (b) are diagrams to explain the test method for the injection test.

After shaking the aerosol spray hair styling agent 1 well, the spray button on the aerosol container is pressed to spray the hair styling agent composition 2 toward the wall surface 3 from a position 15 cm away from the wall surface 3 for 1 second (FIG. 1(a)). The propellant is also sprayed together with the hair styling agent composition 2. In other words, by pressing the spray button, a liquid containing the hair styling agent composition 2 is sprayed.

Next, the area of the region surrounded by the outer edge 2a of the hair styling composition 2 attached to the wall surface 3 is calculated ( FIG. 1( b) ). It is preferable to record the position of the outer edge 2a of the hair styling composition 2 within 10 seconds after spraying the hair styling composition 2. It is also preferable that the material of the wall surface 3 is thermal paper. In FIG. 1( b ), the shape of the outer edge 2a of the hair styling composition 2 is circular, and the area of this circle is 20 ^cm2 or less.

When the spraying test is performed, the area of the region surrounded by the outer edge of the hair styling composition attached to the wall surface is preferably 19.5 ^cm2 or less, more preferably 19 ^cm2 or less. When the area is equal to or less than the upper limit, the hair styling composition can be well attached to the desired location. For example, the hair styling composition can be well spread to the scalp and roots of the hair, and as a result, partial curls of the hair acquired in daily life can be more well corrected.

One method for reducing the area of the region surrounded by the outer edge of the hair styling composition when the spray test is performed is to reduce the nozzle hole diameter (nozzle hole diameter) of the spray button.

The nozzle hole diameter (nozzle hole diameter) of the injection button is preferably 0.3 mm or more, and preferably 2.0 mm or less.

The shape of the outer edge of the hair styling composition attached to the wall surface during the spray test is not particularly limited. The shape of the outer edge of the hair styling composition varies depending on, for example, the number of nozzles of the spray button. The shape of the outer edge of the hair styling composition may be approximately circular, may be circular, or may be any other shape.

The aerosol spray hair styling agent can be prepared by a known method. Examples of methods for preparing the aerosol spray hair styling agent include filling an aerosol spray container with the hair styling agent composition or each of the blended ingredients contained in the hair styling agent composition, clinching the aerosol spray container with an aerosol valve, filling the propellant through the stem, and attaching a suitable spray button to the stem.

In a total of 100% by mass of the hair styling composition and the propellant, the content of the hair styling composition is preferably 20.0% by mass or more, more preferably 30.0% by mass or more, preferably 80.0% by mass or less, more preferably 70.0% by mass or less. When the content of the hair styling composition is equal to or more than the above lower limit and equal to or less than the above upper limit, the ejection properties become even better.
