Description

  The present invention relates to an oily cosmetic containing an ester bond-containing liquid oil gelled with a fructooligosaccharide fatty acid ester, having an appropriate and uniform film thickness of the decorative film, and having a smooth feeling of use, adhesion and gloss The present invention relates to an oily cosmetic that is excellent, has a long-lasting moisturizing feeling, and has good temperature stability.

  Oily cosmetics such as lipstick are usually pigmented into solid oils such as waxes or oily gels obtained by gelling liquid oils with oil gelling agents such as dextrin fatty acid esters and 12-hydroxystearic acid. And a pigment dispersed (Patent Document 1). Conventionally, the use feeling of oily cosmetics has been improved by examining the types of these solid oil agents, or the types and blending ratios of liquid oil and gelling agent. And if you want to get glossy, polar liquid oils such as glycerides and esters are used, but in this case, the surface of the cosmetics is likely to sweat (liquid oil exudation, sweating) at high temperatures. There are inconveniences, and in use, there are problems such as lack of adhesion to the skin and lips, and easy bleeding. Therefore, in order to increase the stability at high temperatures, it has been attempted to increase the blending amount of wax and oil gelling agent. However, as the blending amount increases, the stretch and lack of smoothness are reduced. In some cases, usability was impaired.

Therefore, for example, as shown in Patent Document 2, by blending polyoxypropylene alkyl ether in an oily solid cosmetic, glossy and long-lasting, with improved high-temperature stability, and Patent Document 3 In addition, a solid wax having improved shape retention and usability by blending a solid dialkyl ketone, and further, as shown in Patent Document 4, a hydrocarbon wax containing a polyethylene wax having a specific molecular weight as an essential component By improving the content of oil, oil, and plant wax, those having improved usability, makeup durability, and temperature stability have been proposed. On the other hand, it has been proposed to use inulin sugar fatty acid esters as gel structure imparting agents for volatile cyclic silicones (Patent Document 5).

  However, the oily solid cosmetic blended with the polyoxypropylene alkyl ether as shown in the above-mentioned Patent Document 1 is excellent in gloss of the decorative film and stability over time, but can satisfy the lightness of spreading and the uniformity of the film. It was not a thing. In addition, an oily cosmetic containing a solid dialkyl ketone as disclosed in Patent Document 2 is excellent in non-stickiness, but is not satisfactory in terms of adhesion and stability over time. Furthermore, an oily solid cosmetic containing a hydrocarbon wax having a specific molecular weight polyethylene wax as an essential component as shown in Patent Document 3 and an oil component and a specific amount of a vegetable wax is also spread and smooth. The fit was still not satisfactory. The present invention has been made in view of such a situation, and forms a decorative film having a good gloss with an appropriate and uniform film thickness, is excellent in smooth use feeling and adhesiveness, and maintains a moist feeling. An object of the present invention is to provide an oily cosmetic material having a high temperature stability and excellent temperature stability.

  As a result of intensive research to solve the above-mentioned problems, the present inventors have obtained an oily cosmetic composition containing a liquid oil having an ester bond in order to form a glossy decorative film. The present inventors have found that oily cosmetics gelled with two types of specific fructooligosaccharide fatty acid esters having different degrees can solve the above-mentioned problems.

  That is, the present invention is an oily cosmetic comprising a liquid oil (component (A)) having at least one ester bond in the molecule, the liquid oil having a sugar average polymerization degree of 10 or more and 60 or less, High degree of polymerization fructooligosaccharide fatty acid ester (component (B)) having a degree of fatty acid esterification per monosaccharide unit of 2.2 or more and an average degree of sugar polymerization of 7 or less, and the degree of fatty acid esterification per monosaccharide unit It is an oily cosmetic characterized by being gelled with a fructooligosaccharide fatty acid ester (component (C)) having a low polymerization degree of 2.2 or higher.

  Moreover, the blending ratio of the high polymerization degree fructooligosaccharide fatty acid ester of the said component (B) and the low polymerization degree fructooligosaccharide fatty acid ester of the said component (C) is (B) / (C) = 0.25-4 by mass ratio. Is preferred. The high-polymerized fructooligosaccharide fatty acid ester having a sugar average polymerization degree of 10 to 60 and a fatty acid esterification degree per monosaccharide unit of 2.2 or more is 60 mol of the total acyl group. % Or more is preferably a fructo-oligo fatty acid ester of one or more selected from a hexadecanoyl group, an octadecanoyl group, an eicosanoyl group or a docosanoyl group. Further, the liquid oil having at least one ester bond in the molecule of the component (A) preferably has an IOB value of 0.3 or more in the organic conceptual diagram.

  The oily cosmetic composition of the present invention is a liquid oil having at least one ester bond in the molecule, having a high sugar average degree of polymerization of 10 to 60 and a fatty acid esterification degree per monosaccharide unit of 2.2 or more. Because it contains a gel composition gelled with a degree of polymerization fructooligosaccharide fatty acid ester and a low degree of fructooligosaccharide fatty acid ester having a sugar average degree of polymerization of 7 or less and a degree of fatty acid esterification per monosaccharide unit of 2.2 or more It forms a decorative film with a good gloss and an appropriate and uniform film thickness, is excellent in smooth use feeling and adhesion, has a high moisturizing feeling, and has excellent temperature stability. In particular, when a liquid oil having an IOB value of 0.3 or more is used as a liquid oil having at least one ester bond in the molecule, the gelation effect is good, and the above effect is further improved.

  The present invention will be described in more detail. Examples of the liquid oil having at least one ester bond in the molecule of the component (A) of the present invention include ester oils and glyceride oils, and those commonly used in cosmetics can be used. This component (A) liquid oil is a glossy, moderate and uniform film by gelation of the high polymerization degree fructooligosaccharide fatty acid ester of component (B) and the low polymerization degree fructooligosaccharide fatty acid ester of component (C). A thick cosmetic film is formed, and an oily cosmetic with excellent smooth use feeling and adhesion, high moisturizing durability and excellent temperature stability is formed.

  Examples of the ester oil include diisobutyl adipate, 2-hexyldecyl adipate, di-heptylundecyl adipate, N-alkyl glycol monoisostearate, ethylene glycol di-2-ethylhexanoate, di-2 -Neopentyl glycol ethylhexanoate, oleyl oleate, octyldodecyl oleate, decyl oleate, neopentyl glycol dicaprate, triethyl citrate, 2-ethylhexyl succinate, diisopropyl sebacate, di-2-ethylhexyl sebacate , Dialkyl carbonate, isopropyl palmitate, 2-ethylhexyl palmitate, 2-hexyl decyl palmitate, 2-heptyl undecyl myristate, isopropyl myristate, 2-octyl myristate Decyl, myristic acid-2-hexyl decyl dimethyl octanoate hexyl decyl, hexyl laurate, N- lauroyl -L- glutamic acid-2-octyldodecyl ester, and diisostearyl malate, and the like.

  The liquid oil having at least one ester bond in the component (A) molecule is preferably a highly polar liquid oil having an IOB value of 0.3 or more in order to give a higher gloss or moist feeling. The IOB value (Inorganic Organic Balance) referred to here is based on the organic concept diagram of Satoshi Fujita (see “Chemistry Domain”, pages 11-10 and 719-729). is there. This is an indicator of the polarity of the organic compound, and the higher this value, the higher the polarity. Specific examples of the liquid oil having at least one ester bond in the molecule having an IOB value of 0.3 or more used in the present invention (A) include, for example, neopentyl di-2-ethylhexanoate. Glycol, propylene glycol monocaprate, propylene glycol dicaprate, trimethylolpropane tri-2-ethylhexanoate, diethyl sebacate, diisopropyl adipate, diisopropyl sebacate, glyceryl tri-2-ethylhexanoate, tri (capryl / capric acid) Glycerin, tetra-2-ethylhexanoic acid pentaerythritol, tri-2-ethylhexyl citrate, octyldodecyl lactate, diisostearyl malate, diglyceryl monoisostearate, diglyceryl diisostearate, sorbita sesquioleate Etc., and may be selected those one or two or more appropriately.

  Although the compounding quantity of the component (A) of this invention is not specifically limited, 5-90 mass% in oily cosmetics is preferable, and 10-70 mass% is especially preferable. If the amount is less than 5% by mass, sufficient gloss and moist feeling cannot be obtained, and if it exceeds 90% by mass, an appropriate and uniform film thickness feeling and adhesion cannot be obtained.

  Component (B) is a high-polymerization fructooligosaccharide fatty acid ester having an average sugar polymerization degree of 10 or more and 60 or less and a fatty acid esterification degree per monosaccharide unit of 2.2 or more. Fructooligosaccharide fatty acid esters are known (Japanese Patent Laid-Open Nos. 3-197409 and 2002-193732). The fructo-oligosaccharide which is a raw material of the fructo-oligosaccharide fatty acid ester of the component (B) is an oligosaccharide having fructose as a main constituent sugar. Fructooligosaccharides are contained in various plants such as roots, stems, leaves, and seeds of Asteraceae, Gramineae and Liliaceae, and their structures are such that the main chain has a 2 → 1 bond and 2 → There are two types of 6 bonds. Examples of the 2 → 1 bond include fructooligosaccharides derived from inulin, asparagosin, asphodelan, triticane, criticzan, and Bacmondo, and examples of the 2 → 6 bond include Flaen, Levan, and Ceracan. Either can be used. Among these fructooligosaccharides, inulin is particularly preferable from the viewpoint of physical properties and supply.

The fructooligosaccharide fatty acid ester is obtained by replacing the hydrogen atom of the hydroxyl group of fructooligosaccharide with an acyl group RCO- (wherein R represents a linear or branched alkyl group or alkenyl group having 7 to 32 carbon atoms). That is, this fructooligosaccharide fatty acid ester is obtained by reacting a fructooligosaccharide with a fatty acid represented by the formula RCOOH (where R is the same as above) or a reactive derivative thereof, specifically an acid halide, an acid anhydride, or the like. Manufactured. This reaction can be performed by a conventionally known method. For example, it can be obtained by dispersing fructooligosaccharide in dimethylformamide and pyridine, adding a fatty acid halide or a fatty acid anhydride thereto, and reacting at about 60 ° C. for about 2 hours.

In the component (B) of the present invention, the fatty acid esterification degree per monosaccharide unit is 2.2 or more, that is, an average of 2.2 or more hydroxyl groups are substituted per monosaccharide unit. When the degree of substitution is 2.2 or more, the gel structure is more easily formed because the solubility of the component (A) in the oil-based base material containing the liquid oil is better, and the stability is further improved and the separation is improved. It's hard to get up. On the other hand, if the degree of substitution is lower than 2.2, it is difficult to form a gel structure due to low solubility in an oily substrate, and it may be difficult to ensure stability.

  In addition, in the high polymerization degree fructooligosaccharide fatty acid ester of the component (B) of the present invention, at least 60 mol% of the total acyl groups are selected from hexadecanoyl group, octadecanoyl group, eicosanoyl group or docosanoyl group. Or it is preferable that they are 2 or more types. If the total amount of these acyl groups is 60 mol% or more, the stability of the gel composition or cosmetic of the present invention is further improved. With regard to the carbon chain length of the acyl group, the acyl group having a carbon number smaller than that of the hexadecanoyl group may not give sufficient gel hardness, and conversely, the acyl group having a carbon number greater than that of the docosanoyl group may be heavy when used. The gelling agent may precipitate over time.

  In the fructooligosaccharide fatty acid ester in which 60 mol% or more of the total acyl groups is one or more selected from a hexadecanoyl group, an octadecanoyl group, an eicosanoyl group and a docosanoyl group, the other acyl groups include acetyl groups, Propionyl, butyryl, isobutyryl, valeryl, isovaleryl, pivaloyl, hexanoyl, octanoyl, decanoyl, dodecanoyl, tetradecanoyl, tetracosanoyl, hexacosanoyl, octacosanoyl, triacontanoyl, ole An oil group, a benzoyl group, a naphthoyl group, etc. can be illustrated.

  In the oily cosmetic of the present invention, when it is desired to suppress the shrinkage and cracking of the gel at the same time as ensuring the stability, or to make the gel soft, the acyl group of the fructooligosaccharide fatty acid ester having a high degree of polymerization of the component (B) In this case, an acyl group having a branched hydrocarbon skeleton may be contained. In this case, the acyl group having a branched hydrocarbon skeleton preferably has 22 or less carbon atoms, and particularly preferably 18 or less carbon atoms. Examples of the acyl group having a branched hydrocarbon skeleton that is preferably used include an isostearoyl group, an isohexadecanoyl group, an isodecanoyl group, and an isooctanoyl group.

  Component (C) of the present invention is a low-polymerization fructooligosaccharide fatty acid ester having a sugar average polymerization degree of 7 or less and a fatty acid esterification degree per monosaccharide unit of 2.2 or more. The low-polymerization fructooligosaccharide fatty acid ester of component (C) is made from a fructooligosaccharide having an average sugar polymerization degree of 7 or less, and is the same as the high-polymerization fructooligosaccharide fatty acid ester of component (B) described above. The hydrogen atom of the hydroxyl group was substituted with an acyl group RCO- (where R represents a straight-chain or branched alkyl group or alkenyl group having 7 to 32 carbon atoms) on average 2.2 or more per monosaccharide unit. Fructooligosaccharide fatty acid ester. When the degree of substitution is 2.2 or more, the gel structure is more easily formed because the solubility of the component (A) in the oil-based base material containing the liquid oil is better, and the stability is further improved and the separation is improved. It's hard to get up. On the other hand, if the degree of substitution is lower than 2.2, it is difficult to form a gel structure due to low solubility in an oily substrate, and it may be difficult to ensure stability. Examples of the low-polymerization fructooligosaccharide fatty acid ester of component (C) include Leopard ISK (manufactured by Chiba Flour Mills) as a commercial product.

  The high polymerization degree fructooligosaccharide fatty acid ester of the component (B) used in the present invention has a sugar average polymerization degree of 10 or more and 60 or less. The method for measuring the average degree of polymerization of the sugar is described in, for example, L. De Leenheer, Starch 46 (5), p193-196 (1994), Carbohydrates as Organic Raw Materials, Vol.III, p67-92 (1996). Those having an average sugar polymerization degree of 10 or more and 60 or less can exhibit high gelling ability to a liquid oil having at least one ester bond in the molecule of the component (A) and can impart high gel hardness. However, as shown in the experimental examples and comparative experimental examples to be described later, by itself, a sufficient gelling effect is not exhibited particularly for the liquid oil of the component (A) having a high IOB value. However, when a high polymerization degree fructooligosaccharide fatty acid ester having a sugar average polymerization degree of 10 to 60 and this component (B) is combined with a low polymerization fructooligosaccharide fatty acid ester having a sugar average polymerization degree of 7 or less. In particular, the gelling effect is further improved for the liquid oil of component (A) having a high IOB value, so that a decorative film having a good film thickness, gloss and temperature stability can be formed, and the smoothness can be achieved. An oily cosmetic with excellent and non-stickiness can be obtained. Moreover, by using together with the liquid oil of component (A) having a low IOB value, it is possible to form a cosmetic film having a good film thickness, gloss, and temperature stability, regardless of the gelation effect, and smoothness. And an oily cosmetic without stickiness is obtained.

  In the oily cosmetic of the present invention, the high polymerization degree fructooligosaccharide fatty acid ester of the component (A) can be used alone or in combination of two or more as required. 0.1-30 mass% is preferable and 0.5-20 mass% is especially preferable. If it is less than 0.1% by mass, there is a problem in the stability of the oily cosmetic, particularly at a high temperature. On the other hand, if it exceeds 30% by mass, it becomes hard and unfavorable because the skin and lips are heavy and spread during application. Moreover, the low polymerization degree fructooligosaccharide fatty acid ester of the component (C) of the present invention can be used singly or in combination of two or more as required, and the blending amount thereof is 0.1 to 0.1 in the oily cosmetic. 30 mass% is preferable and 0.5-20 mass% is especially preferable. The blending ratio of the high-polymerization degree fructooligosaccharide fatty acid ester of the component (B) and the low-polymerization degree fructooligosaccharide fatty acid ester of the component (C) is preferably (B) / (C) = 0.25-4 by mass ratio. 0.5 to 2 is particularly preferable. Within this range, the liquid oil of component (A), particularly polar oil having an IOB value of 0.3 or more can be effectively gelled, and an oily cosmetic material having particularly excellent temporal stability can be obtained. If it is less than 0.25 or exceeds 4, sufficient stability over time and usability cannot be ensured.

  In the oily cosmetic of the present invention, the liquid oil of component (A), the high-polymerization fructooligosaccharide fatty acid ester of component (B) and the low-polymerization fructooligosaccharide fatty acid ester of component (C) are essential components, but other than these In addition, liquid and solid oily components, surfactants, alcohols, humectants, gelling agents and thickeners other than components (B) and (C), powders, UV absorption Agents, preservatives, antibacterial agents, antioxidants, skin beautifying agents (whitening agents, cell activators, anti-inflammatory agents, blood circulation promoters, skin astringents, antiseborrheic agents, etc.), vitamins, amino acids, nucleic acids, etc. Can be blended.
