Description

  The present invention relates to a multi-phase molded cosmetic, and more particularly to a multi-phase molded cosmetic having at least one transparent phase.

  In stick-like cosmetics such as lipsticks, cosmetics composed of a plurality of phases having different compositions are known. A typical example is a lip cosmetic comprising a substantially cylindrical inner core (first layer) and an outer peripheral part (second layer) shaped to cover the side surface. These multiphase molding cosmetics have a plurality of properties that are difficult to achieve with a single composition (single layer) in each phase, and both properties are realized by joining them. A phase has an advantage that a desired characteristic can be achieved by compensating for a defect of the other phase (see Patent Document 1).

  For example, Patent Document 2 describes a stick-shaped cosmetic in which volatilization of a volatile oil contained in an inner phase part is suppressed by the outer phase part, and Patent Document 3 uses an inner core part as an aqueous composition. Describes a double-structured stick-type cosmetic material that reduces the oiliness of the oil-based cosmetic material at the outer peripheral portion and imparts a fresh feel. In addition, a stick-shaped lipstick cosmetic (Patent Document 4), in which a composition with low hardness in which a liquid oil component is contained in the inner phase and the outer phase portion as a solid oily composition is maintained in shape retention, remains on the lips For example, there has been proposed a cosmetic for retouching (Patent Document 5) in which a layer containing a component that is familiar with lipstick and a layer that scrapes off the familiar lipstick are integrally molded.

  However, none of these conventional multiphase cosmetics contains a transparent phase. On the other hand, for example, in a multiphase molding cosmetic in which a transparent solid composition containing a thickening substance such as a dextrin fatty acid ester described in Patent Document 6 is placed in contact with another oily composition, There has been a problem that bleeding occurs at the interface or the composition becomes unstable.

Japanese Patent Laid-Open No. 54-113445 JP 63-139107 A Japanese Patent Laid-Open No. 11-269025 JP 2008-105951 A JP 2006-248918 A JP-A-9-235210

  Therefore, the problem in the present invention is that in a multiphase molded cosmetic arranged so that the transparent phase and the opaque phase are in contact, the multiphase molded makeup that does not cause bleeding or destabilization at the interface portion between the transparent phase and the opaque phase. Is to provide a fee.

  As a result of intensive studies to solve the above-mentioned problems, the present inventor uses at least one selected from polyglycerin fatty acid ester and 12-hydroxystearic acid as a thickening component to be blended in the transparent phase. The present inventors have found that a stable molding cosmetic can be obtained without causing bleeding or the like at the contact interface between the transparent phase and the opaque phase, and the present invention has been completed.

  That is, the present invention provides a cosmetic having at least one transparent phase and a plurality of phases including at least one opaque phase, wherein at least a part of the transparent phase is in contact with at least a part of the opaque phase. The transparent phase contains a polyglycerin fatty acid ester and / or 12-hydroxystearic acid, and the polyglycerin fatty acid ester has a polyglycerin having an average degree of polymerization of 2 to 15 and a carbon number of 18 or more. It is composed of one or more selected from linear saturated fatty acids and one or more selected from saturated fatty acids having 8 to 12 carbon atoms, and its esterification rate is 80% or more. Provide multi-phase molding cosmetics.

  The multi-phase molded cosmetic of the present invention has a transparent phase and an opaque phase, does not cause bleeding or the like at their contact interface, and maintains a beautiful appearance. Furthermore, the state of the composition is kept stable even near the interface.

It is a perspective view which shows an example of the multiphase molding cosmetics of this invention. It is a perspective view which shows the other example of the multiphase molding cosmetics of this invention.

The multiphase molded cosmetic of the present invention is a molded oily solid cosmetic having a plurality of phases including at least one transparent phase and at least one opaque phase.
The “transparent phase” in the present invention may be a layer made of an oily solid composition which is visually transparent. For example, the molded composition is attached to a resin cell (10 × 10 × 45 mm optical measurement cell), and (L, a, b) values are obtained by a transmission method using a color analyzer at 25 ° C., and the L value is 1 The phase composed of the above molding composition can be defined as “transparent phase” (see JP-A-1-163111).
On the other hand, the “opaque phase” in the present invention is a layer other than the transparent phase, and may be a phase composed of an oily solid composition that is visually opaque and may be colored or uncolored.

The multiphase molded cosmetic of the present invention is arranged so that the transparent phase and the opaque phase are in contact at least partially. As long as this condition is satisfied, the multiphase molded cosmetic of the present invention may have any shape.
Specific examples of the multiphase molded cosmetic of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing an example of the multiphase molded cosmetic of the present invention, and has a structure in which an outer periphery of a substantially cylindrical transparent phase 11 is covered with an opaque phase 12. The tip portion has an elliptical shape that is cut obliquely with respect to the central axis in the length direction of the transparent phase, and an elliptical transparent phase and an opaque phase that forms the outer periphery thereof are exposed at the central portion.
Such a multi-phase molded cosmetic can be used as a multi-phase lipstick, for example, by making the transparent phase lip gloss and the opaque phase lipstick. By applying the cosmetic on the lips and rubbing the upper and lower lips together, it is possible to make glossy lips.

FIG. 2 is a diagram showing another example of the multiphase molded cosmetic of the present invention. Two transparent phases 11 and opaque phases 12 are arranged in a flat container 20 having a depression on the upper surface so as to form a checkered pattern.
Specifically, for example, a multi-phase molded cosmetic with an eye shadow as an opaque phase, a multi-phase molded cosmetic with gloss for lips as a transparent phase, an eye shadow as an opaque phase, and a transparent eye shadow for gloss as a transparent phase It can be provided in the form of a multiphase molding cosmetic composition in which a foundation is formed as an opaque phase and gloss for lips is disposed as a transparent phase. That is, in the multiphase molded cosmetics of the present invention, the cosmetics used as the transparent phase and the opaque phase may be the cosmetics having the same application site, or the cosmetics having different application sites may be arranged in each, or a combination thereof. Is not limited at all.
The method of using such a multi-phase cosmetic is not limited, but for example, in a multi-phase molded cosmetic including the same eye shadow (opaque phase) and glossy transparent eye shadow (transparent phase), After using eye shadow (opaque), you can apply glossy eye shadow (transparent) to add gloss. Multiphase molded cosmetics having a transparent phase and an opaque phase with different application sites also have the advantage that it is not necessary to carry each cosmetic separately.

  The shape of the multiphase molded cosmetic of the present invention is not limited to that shown in FIG. 1 or 2, but the transparent phase and the opaque phase constituting it are in contact with each other at least partially. is there. However, since the transparent phase contains a thickening component such as polyglycerin fatty acid ester and / or 12-hydroxystearic acid as an essential component, the contact interface is stable and bleeding does not occur.

  The polyglycerin fatty acid ester blended in the transparent phase in the present invention has one or more kinds selected from polyglycerin having an average degree of polymerization of 2 to 15 and linear saturated fatty acid having 18 or more carbon atoms and the number of carbon atoms. It is composed of one or two or more selected from 8 to 12 saturated fatty acids, and among the constituent fatty acids, linear saturated fatty acids having 18 or more carbon atoms are 60% or more, and the esterification rate is 80% or more. Some are used.

The straight-chain saturated fatty acid having 18 or more carbon atoms is not particularly limited, but one having 22 or less carbon atoms is preferably used, and is selected from, for example, stearic acid, arachidic acid, behenic acid, etc. Or 2 or more types are used. When fatty acids with less than 18 carbon atoms are used, or when branched or unsaturated fatty acids are used even with 18 or more carbon atoms, the thickening effect may not be sufficient. Of these, it is particularly preferable to use behenic acid.
Examples of the saturated fatty acid having 8 to 12 carbon atoms include caprylic acid, capric acid, lauric acid, 2-ethylhexanoic acid, and isononanoic acid, and one or more of these are used. Of these, capric acid is particularly preferred.

The constituent fatty acid of the polyglycerol fatty acid ester used as a thickener in the present invention is composed of both a linear saturated fatty acid having 18 or more carbon atoms and a saturated fatty acid having 8 to 12 carbon atoms. And In order to solidify the oil and maintain the strength as a stick, among the constituent fatty acids, the linear saturated fatty acid having 18 or more carbon atoms is preferably 0.3 or more, particularly preferably in a molar ratio to the whole constituent fatty acids. Is 0.6 or more. If it is less than 0.3, the strength as a stick may be insufficient.
On the other hand, among the constituent fatty acids, the saturated fatty acid having 8 to 12 carbon atoms is preferably 0.05 or more in terms of a molar ratio with respect to the whole constituent fatty acid in order to maintain compatibility with the oil and transparency. If the saturated fatty acid having 8 to 12 carbon atoms is not contained, the crystallinity is too high and cannot be solidified transparently.

Examples of polyglycerin include polyglycerin obtained by dehydration condensation using glycerin as a raw material, such as diglycerin, triglycerin, tetraglycerin, pentaglycerin, hexaglycerin, nonaglycerin, decaglycerin, and the like. More than seeds are used. The average degree of polymerization of this polyglycerin is 2 to 15. If the average degree of polymerization is less than 2, the thickening effect is insufficient, and if it exceeds 15, the esterification reaction becomes difficult. In particular, a polyglycerin having an average degree of polymerization of 2 to 6 and a polyglycerin having an average degree of polymerization of 6 to 11 mixed with an average degree of polymerization of 6 to 10 are preferably used.
If a polyhydric alcohol other than the above glycerins, for example, a dihydric alcohol such as propylene glycol is used, the resulting thickening effect may not be sufficient. If a hexahydric alcohol such as sorbitol is used, The compatibility may be worse.

The polyglycerin constituting the polyglycerin fatty acid ester has an average degree of polymerization of 2 to 20. Here, the average degree of polymerization is the average degree of polymerization (n) of polyglycerin calculated from the hydroxyl value by end group analysis. Specifically, the average degree of polymerization is calculated from the following formulas (Formula 1) and (Formula 2).
(Formula 1) Molecular weight = 74n + 18
(Formula 2) Hydroxyl value = 56110 (n + 2) / Molecular weight The hydroxyl value in the above (Formula 2) is a numerical value that is an index of the number of hydroxyl groups contained in polyglycerin, and is free contained in 1 g of polyglycerin. The number of milligrams of potassium hydroxide required to neutralize the acetic acid required to acetylate the hydroxyl group. The number of milligrams of potassium hydroxide is calculated according to the Japan Oil Chemists 'Society edited by “The Japan Oil Chemists' Society, Standard Oil Analysis Test Method (I), 1996 edition”.

  The esterification rate of the polyglycerol fatty acid ester used as a thickener in the present invention is 70% or more. As the esterification rate increases, the thickening effect of the oil component increases, and when the esterification rate is 70% or more, the thickening effect becomes particularly remarkable, and particularly preferably, the esterification rate is 80% or more. Here, the esterification rate is the average degree of polymerization of polyglycerol (n) calculated from the hydroxyl value, the number of hydroxyl groups of this polyglycerol (n + 2), and the number of moles of fatty acid added to the polyglycerol (M). , (M / (n + 2)) × 100 = value calculated by esterification rate (%). The hydroxyl value is a value calculated in the same manner as the hydroxyl value described above.

  The polyglycerin fatty acid ester used in the present invention can be produced by a known esterification reaction. For example, a fatty acid and polyglycerin can be produced by an esterification reaction in the presence of an alkali catalyst such as sodium hydroxide.

  Although the thickener used by this invention may be synthesize | combined by above-described esterification reaction, what is marketed may be used. For example, a product (Deca (behenic acid / capric acid) polyglyceryl-8) marketed by Sakamoto Yakuhin Kogyo Co., Ltd. under the trade name “S-face BC-810” can be used particularly preferably. This polyglycerin fatty acid ester uses behenic acid as a linear saturated fatty acid having 18 or more carbon atoms and capric acid as a saturated fatty acid having 8 to 12 carbon atoms.

  12-hydroxystearic acid used in the transparent layer in the present invention is a hydrogenated ricinoleic acid and is a saturated fatty acid having an asymmetric hydroxyl group at the 12-position carbon.

The blending amount of the polyglycerin fatty acid ester or 12-hydroxystearic acid in the transparent layer of the present invention is 4 to 15% by mass, preferably 5 to 10% by mass when each is blended alone. If the blending amount is less than 4% by mass, the transparent layer itself may become unstable, and if it exceeds 15% by mass, the finish gloss may be inferior.
In the transparent layer of the present invention, polyglycerin fatty acid ester and 12-hydroxystearic acid can be used together, and the total blending amount when used in combination is 4 to 15% by mass, preferably 5 to 10% by mass. The ratio of the amount of fatty acid ester and 12-hydroxystearic acid is preferably in the range of 3: 1 to 1: 3.

The transparent phase of the present invention preferably contains hydrogenated polyisobutene (component A) in addition to the polyglycerin fatty acid ester and / or 12-hydroxystearic acid.
Hydrogenated polyisobutene is also called heavy liquid isoparaffin and has been conventionally used in cosmetics. Specifically, it is a hydrocarbon mixture obtained by copolymerizing isobutene and n-butene and then hydrogenating. The hydrogenated polyisobutene used in the present invention may be one generally used in cosmetics, and a commercially available product can be used as it is. The heavy liquid isoparaffin used in the present invention preferably has an average molecular weight of about 500-2700. More preferably, the average molecular weight is 800 to 1200. Heavy liquid isoparaffin having an average molecular weight of 500 or less has a problem in high-temperature stability, and conversely, if the average molecular weight is 2700 or more, the spread becomes heavy or a film feeling may occur.
The blending amount of the hydrogenated polyisobutene in the base of the present invention is 10 to 80% by mass, preferably 20 to 80% by mass, and particularly preferably 40 to 80% by mass. When the blending amount is less than 10% by mass, transparency and gloss are inferior, and when it exceeds 80% by mass, transparency and spread may be inferior.

The transparent phase of the present invention is further selected from (a) phenyl trimethicone and / or diphenylsiloxyphenyl trimethicone, (b) mineral oil having a viscosity of 50-80 mm ² / s, and (c) octyl methoxycinnamate. It is preferable to contain at least one (component B).
(A) As phenyl trimethicone and / or diphenylsiloxyphenyl trimethicone, those having a viscosity of 25 mm ² / S or less at 25 ° C. are preferable, and as a commercial product, KF− commercially available as diphenylsiloxyphenyl trimethicone 56 (manufactured by Shin-Etsu Chemical Co., Ltd.) and SH556 (manufactured by Toray Dow Corning Co., Ltd.) marketed as phenyl trimethicone. Of these, diphenylsiloxyphenyl trimethicone is particularly preferable.
(B) Mineral oil (light liquid paraffin) having a viscosity of 50 to 80 mm ² / s and (c) octylmethoxycinnamate may be those generally used in cosmetics, and commercially available products can be used as they are. When octyl methoxycinnamate is blended, the transparency can be further improved.
Among the component (C), (a) phenyl trimethicone and / or diphenylsiloxyphenyl trimethicone and (b) mineral oil having a viscosity of 50 to 80 mm ² / s are not limited in their respective amounts. c) With respect to octyl methoxycinnamate, the blending amount is preferably 1 to 10% by mass.
Furthermore, it is preferable that the total amount of the polyglycerin fatty acid ester and / or 12-hydroxystearic acid and the component (A) and component (B) is 80 to 100%.

Furthermore, in the multiphase molded cosmetic of the present invention, it is preferable to blend 10% or more of a common oil component in the opaque phase and the transparent phase, so that the interface becomes easier to adjust.
Specific examples of the oil component that can be blended in either or both of the transparent phase and the opaque phase are as follows.
Examples of liquid oils include hydrogenated isoparaffin, liquid paraffin, squalane, lanolin derivatives, higher alcohols, various ester oils, silicone oils, polyalkylene glycol polyethers and other carboxylic acids, oligoester compounds, terpene hydrocarbon oils, etc. Can be mentioned.
Semi-solid oils include lanolin, shea fat, partially hydrogenated coconut oil, and other vegetable oils, partially hydrogenated jojoba oil, and tetra (behenic acid / benzoic acid / ethylhexanoic acid) pentaerythritol, which are commonly used in cosmetics. Macadamia nut oil polyglyceryl-6-esters behenate, dimer linoleic acid (phytosteryl / behenyl), dipentaerythritol hexaoxystearate and the like can be used.

Commercially available products may be used as the semi-solid oil, and examples thereof include the following.
“Cosmall 168EV / M / AR”, “Sarasco P-B822” (manufactured by Nisshin Oillio Co., Ltd.), “S Face VL-211” (manufactured by Sakamoto Yakuhin Kogyo Co., Ltd.), “YOFCO-MAS”, “Plandour-S” / H / G / PB "(manufactured by Nippon Seika Co., Ltd.)," SOFTISAN649 "(manufactured by Sasol), and" El Deu PS-304 "(manufactured by Ajinomoto Co.).

  In addition, waxes (for example, hydrocarbon waxes such as paraffin wax, microcrystalline wax and polyethylene wax, hydrocarbon semisolid oils such as petroleum jelly, wax, etc.) are added to the transparent phase of the present invention. Also good. However, since the base tends to become opaque due to the addition of waxes, the amount of addition is limited to a range that does not impede the effects of the present invention, specifically, preferably less than 3% by mass, more Preferably, it is less than 1% by mass, and it is preferable that substantially no wax is blended.

The multiphase molded cosmetic of the present invention can be obtained by separately mixing and dissolving the component constituting the transparent phase and the component constituting the opaque phase, filling each in a container, cooling and solidifying.
For example, a multiphase lipstick type cosmetic as shown in FIG. 1 can be manufactured by first molding a cylindrical opaque phase that forms an outer layer, and filling the core hole with a transparent phase to solidify.

  The transparent phase of the present invention may appropriately contain components generally blended in makeup cosmetics such as powder components, color materials, and pearl agents. However, it is limited to blending in a range where transparency is maintained.

  Among coloring materials, inorganic pigments having high concealability such as titanium oxide, iron oxide, and bitumen may impair transparency, so the blending amount is preferably 0.5% or less. In order to obtain a product with a more transparent appearance, it is preferably 0.1% or less, and further, substantially not blended.

  Any organic colorant may be used as long as it is usually used as a raw material for cosmetics. For example, red 201, red 202, red 204, red 205, red 220, red 226, red 228, red No. 405, Orange No. 203, Orange No. 204, Yellow No. 205, Yellow No. 401, Blue No. 404, Red No. 3, Red No. 104, Red No. 106, Red No. 227, Red No. 230, Red No. 401, Red No. 505 Orange 205, yellow 4, yellow 5, yellow 202, yellow 203, green 3 and blue 1 and the like. Since the organic colorant is not so concealed, the blending amount is 0.5% or less, preferably 0.0001 to 0.1% in order to make use of the transparent characteristics.

  The amount of the pearl agent or lame agent is not particularly limited because the transparency is hardly impaired, and the glitter appearance and the cosmetic effect are excellent. Rather, when a pearl agent or a lame agent is blended, it is possible to give the appearance design and an excellent makeup effect while taking advantage of the transparency that is the feature of the present invention.

  As the pearl agent and lame agent, various known ones can be used. Titanium oxide-coated mica, iron oxide titanium oxide-coated mica, such as Bengala titanium oxide-coated mica coated with mica and iron oxide and titanium oxide, and mica Examples thereof include powder with silica sandwiched between the titanium oxide coating layer and the like. Examples of powders other than mica as a base material include powders obtained by coating silica flakes with titanium oxide, powders obtained by coating synthetic mica with titanium oxide, hollow titanium oxides, and the like. In addition, a liquid crystal pigment that develops color depending on the liquid crystal structure, a lamellar agent such as a laminated PET film, a hologram pigment, a metal-coated pigment, or the like may be used, and the kind thereof is not particularly limited.

  Furthermore, in the transparent phase of the present invention, components to be blended with ordinary oily cosmetics can be blended as long as the effects of the present invention are not impaired. In addition to octyl methoxycinnamate, when other oil-soluble ultraviolet absorbers are blended, an effect of improving stability when an organic colorant is blended and an ultraviolet protective effect on the skin can be provided. Specific examples include 4- (tert-butyl) -4′-methoxydibenzoylmethane, octocrylene, ubinal A PLUS (trade name), and polysilicon-15, but are not limited thereto. Moreover, you may mix | blend surfactants, such as an oil-soluble chemical | medical agent (vitamin A, vitamin E and its derivative (s), ascorbic acid derivative, etc.), a dispersing agent.
