DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emulsified composition having excellent scent persistence, and more particularly to an emulsified composition of the type which can be used after washing, in which the scent persists even after washing, especially a shampoo, The present invention relates to an emulsion composition suitable as a hair cosmetic such as a rinse.

[0002]

2. Description of the Related Art Conventionally, a fragrance is blended in many cleaning agents. By blending the fragrance, it is possible to mask the fabric odor of the detergent and to impart comfort during use. In addition, the scent remaining on hair, skin, clothes, etc. is very important because it is always conscious not only by the product user but also by others. Furthermore, the fragrance is representative of the product concept of the product, and greatly affects the consumer's willingness to purchase. Thus, the fragrance is
It affects the usability and effect of the product, and has a great physiological and psychological effect. Therefore, the used fragrance is required to be attractive at the time of use and to have excellent scent persistence after use.

[0003] Fragrances are also incorporated in detergents that are used after being washed off, such as shampoos and rinses, so that the fragrance is required to be maintained even after use. However, in these cleaning agents, because of the form of washing away,
Perfume hardly remains on the hair, and it is difficult to maintain the fragrance after use. In addition, a fragrance having a relatively high vapor pressure hardly remains, making it more difficult to maintain an attractive fragrance during use in a well-balanced manner.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an emulsified composition which maintains a scent even after being used after being washed away, and furthermore, a scent which has a relatively high vapor pressure and is difficult to remain. An object of the present invention is to provide an emulsified composition that maintains the scent and maintains the designed scent in a well-balanced manner.

[0005]

Example 1 A hair cosmetic composition shown in Table 1 was prepared, and the appearance, physical properties and residual odor of the composition were evaluated.

(1) Evaluation method a. Appearance / Physical Properties The viscosity at 30 ° C. and the average particle size of the emulsion at the time of dilution were measured, and the appearance was observed.

Here, the viscosity was measured by a B-type viscometer. The external appearance was visually judged, and those showing a translucent to white emulsion were evaluated as ○, and the others were evaluated as ×. The average particle diameter of the emulsion was measured using a laser diffraction / scattering particle size distribution analyzer LA-910 and an automatic dilution unit LY-101 (both manufactured by HORIBA, Ltd.) after diluting the composition with water.

B. Permeability After about 4 g of the emulsified composition was applied to and washed with 20 g (15 cm) of a hair bundle prepared from human hair, the hair was rinsed, and the water was sufficiently wiped off with a towel. At room temperature 25 ° C, humidity 65H
R, 1 hour, 8 hours, 12
After 24 hours, the residual scent after 24 hours was evaluated according to the following criteria. ◎: Very good ○: Good △: Neither of them ×: Bad

(2) Results As a result, as shown in Table 1, the hair cosmetic composition of the present invention had good lingering scent. The emulsion stability was also good.

[Table 1]

Example 2 Shampoo compositions described in Tables 2 and 3 and Tables 4 and 5
The described rinse composition was prepared. Each of the obtained compositions had a viscosity at 30 ° C. of 2,000 cp or more, exhibited a translucent to white emulsion appearance, and had an average particle size of the emulsion upon dilution of 0.5 to 200 μm. When the residual odor was evaluated in the same manner as in Example 1, all were good (良好) to very good (◎). The emulsion stability was also good.
