Abstract

PURPOSE:To provide a solid or semi-solid oily cosmetic uniform in the coating film therefrom despite adherent feeling, also having spreadability smooth in skin touch. CONSTITUTION:The objective cosmetic containing 30wt.% of an oily ingredient or comprising (A) 100 pts.wt. of the oily ingredient and (B) 0.1-20 (pref. 0.5-10) pts.wt. of fructooligosaccharide powder. The fructooligosaccharide, which is an oligosaccharide with fructose as the chief constituent saccharide, is e.g. a saccharide extracted from Ophiopogonis tuber obtained by drying the roots or their swollen portions of Ophiopogonis tuber or its homologous plants belonging to Liliaceae, or inulin obtained from dahlia, Jerusalem artichoke, or elecampane belonging to Compositae, being pref. 300-10000 in molecular weight. For the fructooligosaccharide powder, it is preferable that the extract be purified through filtration and decolorization, etc., followed by drying.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is
The present invention relates to a solid or semi-solid oily cosmetic having a uniform coating film and having a smooth spread on the skin.

[0002]

BACKGROUND OF THE INVENTION Solid or semi-solid oily cosmetics are prepared by combining solid oils, semi-solid oils and liquid oils in an appropriate combination, or by adding an oily gelling agent to these gels. It is produced by using a liquefied oily base and, if necessary, mixing and dispersing cosmetic powder and the like, solidifying and molding.

The usability and usability of such oily cosmetics depend on the composition of the oily base. When a large amount of a solid wax having a high melting point is blended as an oil component, an excellent feeling of adhesion can be obtained, but on the other hand, there are drawbacks that the skin is hard, the spread is heavy, and the stinginess disappears. In addition, when a wax having a low melting point is blended as an oil, smoothness on the skin can be obtained, but there is a drawback that oily slipperiness is produced, and adhesion and makeup lasting are deteriorated. Further, when a large amount of semi-solid oil is blended, a feeling of adhesion can be obtained, but there is a drawback that the spread is heavy and a sticky feeling is produced. Thus, a satisfactory oily cosmetic could not be obtained only by blending the conventional solid oil and semi-solid oil.

On the other hand, with regard to fructooligosaccharides, it has been reported that saccharides extracted from barley winter are incorporated as a moisturizing agent into cosmetics for skin or hair (JP-A-62-813).
No. 05) is incorporated into solid or semi-solid oil-based cosmetics, but no attempt has been made.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a solid or semi-solid oily cosmetic having a uniform coating film and a smooth spread while having a close contact feeling. The purpose is.

[0006]

Therefore, the present inventors have
In view of the above circumstances, as a result of intensive studies, it was found that by incorporating powdered fructooligosaccharides into an oil-based cosmetic composition, the usability of the oil-based cosmetic composition and the poor usability are remarkably improved, and the present invention is provided. Completed

That is, the present invention provides a solid or semi-solid oily cosmetic containing 30% by weight or more of oil and fructooligosaccharide powder.

In the present invention, any oil can be used as long as it is commonly used in cosmetics, and examples thereof include paraffin wax, ceresin wax,
Microcrystalline wax, carnauba wax,
Solid oils such as candelilla wax, beeswax, wax, gay wax, polyethylene wax, ethylene propylene copolymer, hydrogenated castor oil, pentaerythritol rosin acid, stearic acid, behenic acid, cetyl alcohol, stearyl alcohol; liquid paraffin, squalane, castor oil , Liquid oils or semi-solid oils such as isopropyl myristate, isopropyl palmitate, lanolin, petrolatum, polybutene, olive oil, jojoba oil, macadamia oil, octyldodecyl myristate, and dimethylpolysiloxane. These oil components are blended in an amount of 30 to 99.9% by weight based on the whole oily cosmetic.

Further, fructooligosaccharides are oligosaccharides having fructose as a main constituent sugar, and include, for example, a root of a lily family of the family Liliaceae or a plant of the same genus, or a saccharide extracted from a barley winter in which a huge part of the root is dried, Asteraceae dahlia,
Inulin and the like obtained from Jerusalem artichoke, Oguruma and the like can be mentioned, and among them, those having a molecular weight of 300 to 10,000 are preferable.

In the present invention, the fructooligosaccharide powder may be obtained by directly drying the extract obtained as described above, but it is preferably dried after being purified by filtration, decolorization and the like. Non-powdered fructooligosaccharides are difficult to uniformly disperse in an oily cosmetic, and even if they can be dispersed, the amount of an aqueous component in the cosmetic is large and a preferable usability cannot be obtained.

The amount of the fructooligosaccharide powder blended in the oily cosmetic composition of the present invention is 0.1 with respect to 100 parts by weight of the oil content.
-20 parts by weight, preferably 0.5-10 parts by weight.
If the amount is less than 0.1 parts by weight, it is difficult to obtain the desired effect, and even if the amount is more than 20 parts by weight, no further effect can be obtained, and the appearance and usability are adversely affected. Absent.

In the oily cosmetic of the present invention, in addition to the above-mentioned essential components, powders such as extender pigments, white pigments, coloring pigments, organic powders, pearlescent agents, dyes, etc., within a range not impairing the effects of the present invention, Surfactants, oily gelling agents, fragrances, preservatives, ultraviolet absorbers, antioxidants, cosmetic ingredients and the like can be appropriately selected and added.

The oily cosmetics of the present invention include solid or semi-solid products such as lipsticks, lip balms, control colors, oily foundations and oily white powders, which are produced by the conventional method from the above components. It Here, the fructooligosaccharide powder according to the present invention may be dispersed and blended in the same manner as a general powder component.

EXAMPLES Next, examples will be described.

Examples 1 to 6 and Comparative Examples 1 to 6 (lipsticks) Lipsticks having the compositions shown in Table 1 were prepared and the evaluation items shown in Table 1 were evaluated. (Production method) A. Components (1) to (9) are dissolved by heating. B. Components (10) to (13) are dispersed in A. C. After filling with B, it is cooled to obtain a product. (Evaluation Criteria) ⊙ Very good ○ ∙ Good △ ∙ Normal to somewhat bad × …… Poor (Result) The results are shown in Tables 1 and 2.

[0017]

[Table 2]

As is clear from the results shown in Tables 1 and 2, Examples 1 to 6 in which the fructooligosaccharide powder was added to the basic formulation of Comparative Example 1 were satisfactory in all evaluation items. The feeling of use and usability were very excellent. On the other hand, when a wax having a low melting point is blended (Comparative Example 2) or the amount of wax is reduced (Comparative Example 5), lightness of spreadability and luster are obtained, but a feeling of adhesion is obtained. And the uniformity of the film and the makeup lasting are poor, and a large amount of paste oil is added (Comparative Example 3,
4) In the case of increasing the amount of wax (Comparative Example 6), the adhesiveness is improved, and the goodness such as improved makeup lasting is obtained, but the poor spreadability, poor gloss, and stickiness. A satisfactory product was not obtained.
