Description

  The present invention relates to a polyhydric alcohol gel cosmetic in oil.

  Gel-like oily cosmetics are applied to cosmetics such as lipsticks and lip glosses because they provide a smooth feeling of use.

  On the other hand, polyhydric alcohol-in-oil type cosmetics in which polyhydric alcohol is emulsified in oil using a surfactant have been developed so far to give the skin a moist feeling and good skin familiarity. However, in order to stably disperse a large amount of polyhydric alcohol in the oil, a large amount of surfactant must be added. As a result, stickiness occurs and the usability of the oily cosmetic may be lowered.

  In Patent Document 1 below, a polyhydric alcohol-in-oil solid in which polyhydric alcohol is emulsified and dispersed in an oil component using silicic anhydride for the purpose of eliminating the poor usability that occurs when a surfactant is used. Cosmetics have been proposed.

JP 2001-72525 A

  However, the method of blending silicic anhydride has problems that the feeling of use becomes heavy and the cosmetic is difficult to extend. In order to make the feeling of use in gel-like oily cosmetics even higher, blending of polyhydric alcohol is considered to be an effective means, but satisfies both usability and dispersion stability while enhancing the feeling of use. The actual situation is that the technology to be used has not yet been provided.

  The present invention has been made in view of the above circumstances, is familiar to the skin, can give a moist feeling, is not sticky while having sufficient dispersion stability, and is excellent in usability and usability. An object is to provide an alcohol-type gel cosmetic.

  The polyhydric alcohol gel cosmetic composition of the present invention that solves the above problems is a 0.4% esterification product of glycerin condensate having an average degree of polymerization of 5 to 12, behenic acid, and eicosane diacid. -4% by mass, 1-10% by mass of glycerin, 3-8% by mass of dextrin palmitate, and 50-95% by mass of liquid oil. The content of each component is based on the total amount of cosmetics.

  In the present specification, the “gel cosmetic” refers to a cosmetic that is not fluid at room temperature (25 ° C.). In the present specification, the “liquid oil” refers to a liquid that is liquid at room temperature (25 ° C.).

  According to the present invention, by containing the above-mentioned components in the above-mentioned specific ratio, the skin is well-familiar and can give a moist feeling, and the dispersion stability is sufficient, but it is not sticky, and has excellent usability and usability. It is possible to realize a polyhydric alcohol gel cosmetic in oil.

  In the polyhydric alcohol gel cosmetic composition of the present invention, the esterification product is preferably (behenic acid / eicosanedioic acid) polyglyceryl-10. In this case, the oily polyhydric alcohol gel cosmetics with excellent skin feel and usability can be obtained more reliably and more easily while being familiar with the skin and imparting a moist feeling while being sufficiently stable in dispersion. It can be easily realized.

  In the polyhydric alcohol gel cosmetic in oil of the present invention, the content of the esterification product is preferably 0.5 to 3% by mass based on the total amount of the cosmetic. In this case, non-stickiness and dispersion stability can be achieved at a higher level.

  Moreover, in the polyhydric alcohol gel cosmetic in oil of this invention, it is preferable that content of dextrin palmitate is 3-6 mass% on the basis of cosmetics whole quantity. In this case, it becomes easy to reduce the stickiness of the cosmetic.

  According to the present invention, there is provided a polyhydric alcohol gel cosmetic in oil that is well accustomed to the skin, can give a moist feeling, is non-sticky while having sufficient dispersion stability, and has excellent usability and usability. be able to.

  Hereinafter, the polyhydric alcohol gel cosmetic in oil of the present invention will be described in detail.

  The polyhydric alcohol gel cosmetic in oil of the present invention is an esterification product of glycerin condensate having an average degree of polymerization of 5 to 12, behenic acid and eicosandioic acid based on the total amount of cosmetic. -4% by mass, 1 to 10% by mass of glycerin based on the total amount of cosmetics, 3 to 8% by mass of dextrin palmitate based on the total amount of cosmetics, and 50 to 95% by mass of liquid oil based on the total amount of cosmetics It contains.

  The above esterification product can be obtained by the following method.

  As the first method, there can be mentioned a method in which a condensate of glycerin having an average degree of polymerization of 5 to 12, behenic acid and eicosane diacid are simultaneously oligoesterified. As a second method, a condensate of glycerin having an average degree of polymerization of 5 to 12 and behenic acid are esterified, and then this reaction product is subjected to eicosanedioic acid and oligoesterification or transesterification. The method of letting it be mentioned. As a third method, a condensate of glycerin having an average polymerization degree of 5 to 12 and eicosane diacid are subjected to an oligoesterification reaction, and then this reaction product is subjected to an esterification reaction with behenic acid. Can be mentioned.

  The esterification reaction is carried out in the presence or absence of an acid, alkali or metal catalyst, preferably in an organic solvent or / and a gas inert to the esterification reaction, at a temperature of 100 to 240 ° C. for several hours to 20 hours. This can be done by removing the water produced. The transesterification reaction can be carried out at a temperature of 20 to 140 ° C. for several tens of minutes to several tens of hours using a catalyst such as metal alcoholate or lipase. The degree of progress of these reactions can be evaluated by measuring the acid value in the system or the composition of the acid component in the free state, whereby the end point of the reaction can be determined. The esterification or transesterification reaction product may contain unreacted glycerin condensate, behenic acid and eicosanedioic acid, and may further contain by-product fatty acids, low molecular weight glycerides, and the like. If necessary, these can be separated and removed by a known method such as washing with water and alkaline deoxidation, and further, decolorization and deodorization treatment can be performed as necessary.

  Examples of the glycerin condensate having an average degree of polymerization of 5 to 12 include pentaglycerin, hexaglycerin, heptaglycerin, octaglycerin, nonaglycerin, decaglycerin, undecaglycerin, dodecaglycerin, and the like. Or it can be used as a mixture of two or more.

  In the polyhydric alcohol gel cosmetic in the present invention, it is preferable to contain an oligomer ester represented by the following general formula (1) as the esterification product.

式（１）中、Ｒは、−ＣＯ（ＣＨ_２）_２０ＣＨ_３、又は水素原子を示し、ｍ及びｎはそれぞれ独立に、３〜１０の整数を示す。

In formula (1), R represents —CO (CH ₂ ) ₂₀ CH ₃ or a hydrogen atom, and m and n each independently represents an integer of 3 to 10.

  The polyhydric alcohol gel cosmetic in oil of the present invention preferably contains (behenic acid / eicosanedioic acid) polyglyceryl-10 as the oligomer ester represented by the general formula (1). As (behenic acid / eicosanedioic acid) polygluceryl-10, a commercially available product “NOMCOAT HK-P” (trade name, manufactured by Nisshin Oilio Group, Inc.) can be used. This “NOMCOAT HK-P” is an oligomer ester consisting of behenic acid, eicosanedioic acid and decaglycerin in which m and n in the general formula (1) are approximately 8.

  The content of the glycerin condensate having an average degree of polymerization of 5 to 12, the esterification product of behenic acid and eicosanedioic acid in the polyhydric alcohol gel cosmetic of the present invention is 0 based on the total amount of the cosmetic. It is necessary to be 4 to 4% by mass. If the content is less than 0.4% by mass, sufficient dispersion stability cannot be obtained, and if it exceeds 4% by mass, stickiness occurs and good usability cannot be obtained, and the skin is familiar and moist. The feeling decreases. In this invention, it is preferable that content of the said esterification product is 0.5-3 mass% on the basis of cosmetics whole quantity. In this case, non-stickiness and dispersion stability can be achieved at a higher level.

  As glycerin, those usually blended as a raw material for cosmetics can be used.

  The content of glycerin in the polyhydric alcohol gel cosmetic in the oil of the present invention needs to be 1 to 10% by mass based on the total amount of the cosmetic. When the content of glycerin is less than 1% by mass, not only the effect of improving skin familiarity is not sufficiently obtained, but also a cosmetic material with good elongation is hardly obtained. On the other hand, when the content of glycerin exceeds 10% by mass, it is difficult to sufficiently reduce stickiness while ensuring dispersion stability. That is, in the present invention, the content of glycerin is required to be 1 to 10% by mass on the basis of the total amount of the cosmetic from the viewpoint of making the gel stretchability and the less stickiness compatible at a higher level.

  As a dextrin palmitate, a commercially available product “Leopard KL2” (trade name, manufactured by Chiba Flour Mills Co., Ltd.) can be used.

  The content of dextrin palmitate in the polyhydric alcohol gel cosmetic in the present invention is required to be 3 to 8% by mass based on the total amount of the cosmetic. If the content of dextrin palmitate is less than 3% by mass, it will be difficult to keep the cosmetic in a gel state. If it exceeds 8% by mass, the skin will not be well-familiar or moist and will not be sticky. It comes to occur. In the present invention, since it becomes easy to reduce the stickiness of the cosmetic, the content of dextrin palmitate is preferably 3 to 6% by mass based on the total amount of the cosmetic.

  Examples of the liquid oil used in the present invention include non-polar hydrocarbon oils such as liquid paraffin and squalane, oils and fats such as olive oil, macadamia nut oil and jojoba oil, higher fatty acids such as oleic acid, tall oil fatty acid and isostearic acid, and lauryl. Chains such as higher alcohols such as alcohol, oleyl alcohol, isostearyl alcohol, octyldodecanol, esters such as isocetyl isostearate, myristyl myristate, isopropyl palmitate, dimethylpolysiloxane, methylphenylpolysiloxane, methylhydrogenpolysiloxane UV absorbers such as polysiloxane and benzophenone derivatives, and fragrances. These can be used alone or in combination of two or more.

  The content of the liquid oil in the polyhydric alcohol gel cosmetic in the oil of the present invention needs to be 50 to 95% by mass based on the total amount of the cosmetic. When the content of the liquid oil is less than 50% by mass, it becomes difficult to obtain a gel cosmetic with good elongation, and when it exceeds 95% by mass, it is difficult to keep the cosmetic in a gel.

  The polyhydric alcohol gel cosmetic in oil of the present invention can contain a solid or semi-solid oil as an oil other than the liquid oil. The solid or semi-solid oil content is not particularly limited as long as it is a solid or semi-solid oil component at room temperature (25 ° C.).
