Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a liquid cosmetic composition, and more specifically, it improves pigment dispersibility in a liquid makeup cosmetic composition such as mascara, eyeliner, eyebrow, eye shadow, and lipstick. Moreover, the present invention relates to a liquid makeup cosmetic having high stability over time.

[0002]

2. Description of the Related Art Conventionally, makeup cosmetics use pigments as colorants, and in order to prevent sedimentation or aggregation with time, the viscosity of the cosmetics is increased, or the pigments are finely divided. ing. However, it has been difficult to completely prevent the sedimentation and aggregation of the liquid makeup cosmetics with the use of the above means due to the limitation of viscosity. It is possible to use a dye as a colorant in order to improve such a defect, but since the dye has a large dyeing property, there was a problem that the dye could not be completely washed off and a coating mark remained. . Further, since the dye dissolves in water or oil, the applied cosmetic has a drawback that it bleeds or is removed by tears, sweat or sebum. Further, it has been studied to add a dispersant such as a surfactant, but it was insufficient from the viewpoint of stability with time and safety.

[0003]

Therefore, an object of the present invention is to provide a liquid makeup cosmetic composition which has high stability over time, is suitable for adhesion and color development, and has a good feeling when applied to the skin. To provide.

[0004]

[Means for Solving the Problems] In view of the above circumstances, the present inventors have conducted extensive studies to solve the above problems, and as a result, by adding a collagen hydrolyzate extracted from fish. The inventors have found that a liquid makeup cosmetic having a better dispersibility of the pigment than that of the conventional one and thus having a high stability over time can be obtained, and completed the present invention.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is described in detail below.
That is, the liquid makeup cosmetic of the present invention is characterized by containing a hydrolyzate of collagen extracted from fish.

[0006] Examples of the origin of collagen include fish such as salmon, trout, cod, salmon and tilapia. From the results of the study, it was found that the incorporation of a hydrolyzate of collagen extracted from fish can prevent pigment aggregation and improve the stability over time. Furthermore, the most preferable result was obtained from freshwater fish-derived collagen in terms of odor and color.

[0007] The fish-derived collagen hydrolyzate of the present invention may be used as it is, and if necessary, it may be subjected to treatments such as concentration, dilution, filtration, and decolorization and deodorization with activated carbon before use. Is also good. Furthermore, the extracted solution may be concentrated to dryness, spray-dried, freeze-dried and the like and used as a dried product. The hydrolysis method includes, but is not particularly limited to, enzymatic decomposition with pepsin or the like and succinylation treatment under acidic conditions. Further, considering the solubility and the stability of the product, the average molecular weight of the hydrolyzate is preferably 1,000 to 70,000.

The amount of collagen extracted from fish in the present invention is not particularly limited as long as it does not impair the effects of the present invention, but 0.0001 to 20% by weight as a solid content is preferable. If it is less than 0.0001% by weight, the effect may not be exhibited, and if it exceeds 20%, the effect is not enhanced and it is uneconomical.

As a result of further studies, it was found that the effect is further improved by using a hydrolyzate of collagen extracted from fish in combination with a water-soluble polysaccharide. Examples of the water-soluble polysaccharides used in the present invention include, for example, cellulose-based water-soluble polymers such as methyl cellulose and hydroxyethyl cellulose, water-soluble plant extracts such as carrageenan, xanthan gum, pullulan, and microbial metabolites such as glycosphingolipids. The resulting water-soluble polymer may be mentioned, and one or more of these may be contained. Among them, cellulose-based water-soluble polymers, water-soluble polymers obtained from microbial metabolites are particularly preferable, and further, hydroxymethyl cellulose or a salt thereof, xanthan gum, pullulan, and glycosphingolipids are highly effective in suppressing reaggregation of pigments. Was given.

The amount of the water-soluble polysaccharide used in the present invention is not particularly limited as long as it does not impair the effects of the present invention, but it is preferably 0.02 to 5% by weight. 0.
If it is less than 02% by weight, the effect may not be exhibited, and if it is more than 5% by weight, the effect is not enhanced and it is uneconomical.

The liquid make-up cosmetic of the present invention may be a cosmetic that is in a fluid state at room temperature, but from the viewpoint of usability, the viscosity at 25 ° C. is preferably 5000 mPa ·
s or less.

It goes without saying that, in addition to the above-mentioned essential components, an aqueous component, an oil component, an organic or inorganic pigment and a suitable surfactant within the range of the amount and quality that do not impair the effects of the present invention, depending on the purpose. A pH adjusting agent, a preservative, a viscosity adjusting agent such as a gelling agent, and the like can be appropriately used as necessary. Further, by making full use of the emulsification technique, a water-in-oil type or oil-in-water type makeup cosmetic can be obtained.
