Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic and, more particularly, to a foam cosmetic for hair which is excellent in both usability and performance.

[0002]

2. Description of the Related Art Hair cosmetics can be used in the form of liquid, paste, gel, mist, foam, and the like. In particular, foam is dripping at the time of application. Can be compatible with good stretch on the hair,
In addition, there are many excellent points such as easy adjustment of the amount of application. In order to make the undiluted solution foamy during use (at the time of application), the undiluted solution and the propellant are simultaneously ejected from the pressure-resistant container, so that the propellant in the ejected content is vaporized in the liquid and foams the content. The aerosol type is generally used.

[0003] In order for these foamed cosmetics to exert their performance to the fullest, not only the performance of the stock cosmetic solution but also the rheological properties of the foam when applied to hair, such as hardness, stickiness, elongation and brittleness. Despite the fact that adaptation is a major factor that has a direct effect as well as the coating thickness of the undiluted solution, no systematic investigation has been made on these, and a satisfactory foamy cosmetic has been found. I couldn't do that.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The measuring apparatus shown in FIG.
It is used when digitizing .about..theta.4. In the apparatus, when a force is applied to the sample (foam) by the movement of the plunger (A), a force for compressing the foam is applied, and finally a flow is generated inside the foam. When the compression is continued to the vicinity of the bottom surface of the saucer (B), the foam strongly shows the combined action of the compression resistance and the flow resistance. Next, when the plunger is raised, it is pulled by the plunger, so that the foam flows in the opposite direction to the compression. The flow of the foam cannot catch up with the displacement of the plunger, and a large negative load is applied to the plunger due to the flow resistance of the foam. However, flow resistance gradually arises because the flowability is gradually restored. Then, when the plunger is lowered, the flow resistance of the foam is also added to the "one" part since it starts by crushing the "one" of the foam formed during the first measurement. This temporal change indicates the characteristics of the foam due to an externally applied force (external force), and the characteristics obtained as information are elastic characteristics (θ1), apparent rigidity characteristics (θ2), and viscous characteristics (θ3). (Aerosol packaging technology-from basics to applications-; co-authored by the Japan Aerosol Association Technical Committee, Toyo Aerosol Industry Co., Ltd., Research Department).

First, the measurement is performed at 25 ° C. and 60% humidity for 16 hours or more.
% Using a test sample (foamed cosmetic) placed in an environment of 90%
After filling an excess amount of foam uniformly into an acrylic resin cylindrical container (B) having a depth (inner size) of 15 mm,
The surface of the foam was quickly flattened, and the foam surface was flattened and immediately fixed horizontally. In contrast to (B), the bottom surface of a clean and dry acrylic resin cylinder (A) having a smooth surface of 60 mm in diameter and 600 mm in height was (B). 30mm above the inner bottom surface (O
From (point), the reciprocating motion is performed twice at a speed of 3.0 mm / sec in a vertical direction so that the extension of the central axis of (A) passes through the center of (B) and at a point of 3 mm above the inner bottom surface of (B). The horizontal axis represents the distance from point O to (A) the bottom surface, the vertical axis represents the stress that (A) receives from the foam due to the reciprocating motion, and the horizontal axis represents the vertical axis such that the measured value per mm is 4 mm. Is the measured value 1
In an orthogonal coordinate system having a ratio per gf (9.8 × 10 ⁻³ N) of 0.6 mm, as shown in FIG. 2, an approximate straight line or a drawing line at each point and the horizontal axis are used. Angle θ
1, θ2, θ3 and θ4 (θ1 is the elastic property of the foam, θ
2 corresponds to rigidity characteristics, θ3 corresponds to viscous characteristics, and θ4 corresponds to stiffness).

In FIG. 2, as the plunger descends, it follows the X axis from the point O, and the load starts to increase after coming into contact with the sample. This rising angle is defined as θ1. Eventually, when it exceeds the elastic limit (X), it becomes a gentle straight line. The angle between the straight line portion and the X axis is θ3. Next, the rise of the load stops at a point (Y) 3 mm above the inner bottom surface of the tray B. A straight line connecting the load rising start point on the X axis and Y is provided, and the angle between the straight line and the X axis is defined as θ2. The load decreases with the rise of the plunger A, and eventually becomes a negative value. Thereafter, when the plunger reaches point O, it reaches point Z in FIG. Next, when the plunger starts lowering again, the load starts to increase and eventually reaches the point Y '. The angle between the rising substantially straight line and the X axis is θ4.

[0011] The overall performance of the foam cosmetics, including the sensory properties, depends on the factors originating in the basic composition of the cosmetics and the properties of the foams. To ensure a uniform and strong film on the hair surface of the target area while ensuring the sensuality (rich feeling) when crushing and excellent operability at the time of application, to easily complete the target hair style In the rheological properties of the foam obtained by the test method described above, the elastic property value is 1.2 to 1.4 radians, the apparent rigid property value is 0.7 to 1.3 radians, and the viscosity property value is 0.3 ~
The strength value of the stiffness must be 0.8 radians and 0.1 to 0.2 radians. Particularly, this effect is remarkably exerted in a so-called hard set type foam cosmetic for the purpose of fixing and maintaining hair arbitrarily adjusted by the foam cosmetic. And it is good in a foamy cosmetic for hair containing at least a film forming agent, a surfactant and water as components.
