DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fragrance cosmetic, and more particularly to a non-ethanol type fragrance cosmetic.

[0002]

2. Description of the Related Art In cosmetics for fragrance, ethanol has been used as a solvent for a long time. This is because ethanol has appropriate volatility, has a small amount of base odor, does not hinder the fragrance, and is excellent in safety to the human body and ability to dissolve the fragrance.

In recent years, however, there has been a report that ethanol affects the ozone layer due to environmental problems. Therefore, there is a movement to regulate the use of ethanol, as in California, USA.

[0004] Under such circumstances, various attempts have been made in the cosmetics industry in Japan to reduce the amount of ethanol used as much as possible. For example, emulsifying or solubilizing a fragrance with a surfactant, encapsulating the fragrance with a host compound such as β-cyclodextrin, and then dispersing the inclusion compound in an aqueous carrier. A method has been proposed in which the adsorbed material is adsorbed on a porous adsorbent and then the adsorbed material is dispersed in an aqueous carrier.

However, each of these methods has serious drawbacks and is still insufficient as a countermeasure. The emulsification or solubilization type fragrance by the method described above has a disadvantage that the quality of the fragrance is poor, and because it contains a surfactant, it becomes sticky and the feeling of use is poor, and when it is attached to clothes, oil bleeding due to the active agent can occur. In the case of the fragrance of the inclusion compound dispersion type according to the method of the above, there is a disadvantage that the included fragrance is hard to be released, so that the fragrance is very weak and is not suitable as a cosmetic for fragrance. In this case, the adsorptivity of the porous adsorptive carrier and the releasability after adsorption differ depending on the constituent components of the fragrance, so that there is a drawback that the quality of the scent is changed and white powder is blown out by the carrier itself.

[0006] As described above, at present, no cosmetics for non-ethanol or fragrance having a low ethanol content have been developed.

[0007]

SUMMARY OF THE INVENTION Accordingly, the present invention eliminates all of the above-mentioned disadvantages of the prior art, and provides a good feeling of use without producing stains or white powder, without changing the quality of the fragrance, and It is an object of the present invention to provide a non-ethanol type fragrance cosmetic which is strong and is useful for environmental protection.

[0008]

Means for Solving the Problems and Actions In view of the above-mentioned situation in the prior art, the present inventor has conducted intensive studies. As a result, when a fragrance is blended with an aqueous carrier together with a methacrylate resin powder, the conventional technique is achieved. The present inventors have found that a non-ethanol type cosmetic for fragrance which can remove all the disadvantages can be obtained, and completed the present invention.

That is, the fragrance cosmetic composition of the present invention which does not contain ethanol is prepared by mixing 0.1 to 10% by weight of methacrylate resin powder, 1 to 20% by weight of fragrance and water , and adding methacrylate resin powder. It is characterized in that the amount of the fragrance is larger than the amount of the body.

The fragrance cosmetic of the present invention will be described below. The methacrylic acid ester resin powder used in the present invention is obtained by subjecting at least one kind of methacrylic acid ester monomer to radical polymerization in a usual manner, for example, in the presence of a polymerization initiator such as benzoyl peroxide. The copolymer may be manufactured by crushing with a crusher or the like,
Alternatively, at least one kind of methacrylic acid ester monomer may be emulsion-polymerized as fine emulsified particles, and after removing the solvent, the resulting spherical hollow polymer or copolymer particles may be directly dried to produce the latter. Spherical hollow powder obtained by emulsion polymerization is preferred.

Examples of the ester group of the methacrylic acid ester include ethylene glycol, methyl, ethyl and the like, but are not particularly limited as long as the resulting polymer or copolymer is not altered by other components such as fragrance.

The particle size of the methacrylate resin powder obtained as described above is 100 μm or less, particularly 10 μm.
The following is preferred. This is because the larger the particle size, the easier it is to settle and become a cake, and the more difficult it is to re-disperse when shaken.

The amount of the methacrylic acid ester resin powder varies depending on the amount of the fragrance, but the appropriate amount of the fragrance in the fragrance cosmetic is 1 to 20% (% by weight, hereinafter The same)
A range of 0.1 to 10% is appropriate. If the amount of the resin powder is less than 0.1%, the fragrance floats as oil droplets, which is not appropriate. If the amount exceeds 10%, it becomes difficult to uniformly disperse the fragrance in the cosmetic. Similarly, it is not suitable because it becomes powdery and the feeling of use is impaired.

As the fragrance, any known fragrance fragrance can be used. The compounding amount is suitably in the range of 1 to 20%. This is because if the fragrance is less than 1%, the fragrance is weakened, so that it is not suitable for fragrances. If it exceeds 20%, the fragrance is too strong and also unsuitable for fragrances.

The fragrance cosmetic of the present invention contains an aqueous carrier for dispersing the above-mentioned resin powder and fragrance, but is used in ordinary cosmetics as far as the effects of the present invention are not impaired. Optional components such as surfactants, preservatives, antioxidants, powders, humectants and the like can be added.

[0016]

The present invention will be described in more detail with reference to the following examples.

[0017]

[Example 1] (Example of cologne)

[0018]

[Table 1] In a solution obtained by stirring and dissolving the component A shown in Table 1 at room temperature, the component B previously pulverized by a pulverizer (equipped with a 1 mm herringbone screen) was dispersed by a disperser to obtain an eau de cologne.

[0019]

[Example 2] (Example of an auto tore)

[0020]

[Table 2]

The C component shown in Table 2 is dissolved at room temperature to form a solution. On the other hand, the A component is pulverized with a pulverizer (equipped with a 1 mm herringbone screen), and the B component is added thereto and kneaded well. Next, this kneaded material was dispersed in the solution of the component C with a disperser to obtain an autotore.

[0022]

Embodiment 3 (Example of Aude Parfum)

[0023]

[Table 3]

The component B shown in Table 3 was stirred and dissolved at room temperature, and a solution of the component A was added to the solution to disperse and dissolve it uniformly. The solution was previously pulverized with a pulverizer (with a 1 mm herringbone screen). The obtained C component was dispersed by a disperser to obtain eaude parfum.

[0025]

Embodiment 4 (Example of cologne)

[0026]

[Table 4]

The component A shown in Table 4 was dissolved and dispersed by stirring at room temperature, and the component B, which had been ground in advance with a pulverizer (equipped with a 1 mm herringbone screen), was dispersed with a disperser to obtain an cologne. .

[0028]

[Comparative Example 1]

[0029]

[Table 5] The components shown in Table 5 were stirred and dissolved at room temperature to obtain cologne.

Next, in order to compare the cologne of Example 4 with the cologne of Comparative Example 1, a comparative use test was conducted by a panelist. This test was conducted by asking ten panelists to answer a questionnaire. Table 6 shows the results.

[0031]

[Table 6] From this table, it can be seen that the cologne of the present invention does not use ethanol, but has the same usability as the cologne using ethanol.

[0032]

EFFECT OF THE INVENTION The fragrance cosmetic of the present invention not only has a feeling of use equivalent to that of a cosmetic containing ethanol, but also does not contain ethanol, even though it does not contain ethanol. It is beneficial for environmental protection. Moreover, it has the feature that it does not generate stains or white powder, does not change the quality of the scent, and has a strong scent.
