DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic for hair, and more particularly, to excellent use sensation and excellent performance in imparting a straight feeling or a glossy feeling or in giving a wet feeling and a soft wave habit. The present invention relates to a foamy cosmetic for hair.

[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 coating amount. 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 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 the force (external force) applied from the outside, and the characteristic obtained as information is the elastic characteristic (θ
1) Apparent rigidity characteristics (θ2), viscous characteristics (θ3) and stiffness (θ4) (Aerosol packaging technology-from basics to applications-; Japan Aerosol Association Technical Committee, Toyo Aerosol Industrial Co., Ltd.) Co-authored by Corporate 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 smoothed out, and the foam surface was flattened and immediately fixed horizontally. In contrast to this (B), a clean and dry acrylic resin cylinder (A) having a smooth surface of 60 mm in diameter and 60 mm in height was used.
(B) at a speed of 3.0 mm / sec in the vertical direction so that the extension of the central axis of (A) passes through the center of (B) from the point (O point) 30 mm above the inner bottom surface. 3m above inner bottom
When the reciprocating motion is performed twice to the point m, the horizontal axis represents the distance from the point O to the bottom of the (A), and the vertical axis represents the stress that (A) receives from the foam due to the reciprocating motion. Is 4 mm so that the measured value is 1 gf (9.
In a rectangular coordinate system having a ratio of 8 mm per 8 × 10 ⁻³ N), as shown in FIG. 2, an angle θ1 between an approximate straight line or a drawing line at each point and a horizontal axis, θ2,
θ3 and θ4 (θ1 corresponds to the elastic property of the foam, θ2 corresponds to the rigid property, θ3 corresponds to the viscous property, and θ4 corresponds to the stiffness)
Do in search of.

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 including the sensory properties of the foamy cosmetics depends on the factors derived from 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 above-mentioned test method, the elastic property value is 1.2 to 1.5 radians when the purpose is to give a feeling of straightness and gloss, and the apparent rigidity property is Value is 0.5-1.1 radian, viscosity characteristic value is 0.2-0.1 radian.
4 radians, Koshi strength value is 0.3-0.5 radians,
For the purpose of giving a wet feeling and giving a soft wave, the elastic characteristic value is 0.9 to 1.1 radian, the apparent rigid characteristic value is 0.5 to 1.2 radian, and the viscosity characteristic is The value should be 0.2-0.7 radians and the strength value of the stiffness should be 0.05-0.2 radians.
