Description

  The present invention relates to an oily solid cosmetic.

  Oily solid cosmetics are products having a central role in the cosmetics market, and various products have been developed. Oil-based solid cosmetics are cosmetics intended to be applied to solid skin at room temperature. Typical examples of these are lipsticks, metal and plastic dishes (jars) molded into sticks. ) Etc. There is a cheek color filled. Most of the oily solid cosmetics are based on organic dyes, inorganic dyes, pigments, etc. based on solid oils that are solid at room temperature, liquid oils that are liquid at room temperature, and paste oils that are pasty at room temperature It is manufactured by pouring a composition liquefied by heating into a metallic lipstick mold, a resin molding capsule, a jar, or the like.

  Oil-based solid cosmetics are required to be able to be applied uniformly with a smooth feel during application, while stick-type cosmetics are required to have sufficient strength such as not to break during application. Moreover, the machine suitability which can respond to a machine filling is good at the time of manufacture, and favorable filling property and moldability are calculated | required.

  Conventionally, the above-mentioned required performance has been satisfied by adjusting the blending ratio of solid oil, liquid oil, paste oil, or the like, which is an oily base, or by selecting each component to be used. At this time, in order to smooth the feeling of use and apply uniformly, the blending amount of the solid oil was reduced as much as possible to soften the finished hardness. However, if the amount of the solid oil is small, the heat resistance is reduced, the product fluidity is increased in summer when the temperature is high, and the product flows out of the container. It is easy to see the defect that sweating which is oil floating occurs.

  Among these disadvantages, sweating is considered to be caused by the following causes. One is thermal expansion due to melting of the oily base, one is a decrease in retention performance of the liquid oil due to a change in crystal structure, and substitution of moisture in the air with oil in the cosmetic.

  Under such circumstances, an oily solid cosmetic using a gelling agent has been proposed in order to reinforce the crystal structure and prevent a decrease in liquid oil retention performance. For example, Japanese Patent Laid-Open No. 2006-52155 (Patent Document 1) includes 0.1 to 10% solid oil, branched fatty acid, glycerin and / or diglycerin ester, and inulin fatty acid ester as a gelling agent. Oil-based solid cosmetics exhibiting good stability without smooth spreading and sweating are disclosed.

  JP-A-2005-163029 (Patent Document 2) discloses liquid oils such as octyldodecanol, 12-hydroxystearic acid and cyclomethicone, and N-butyl-2- (N′-lauroylamino) as a gelling agent. Stick-like cosmetics using glutarimide, N-lauroyl-L-glutamic acid dibutylamide, N-2-ethylhexanoyl-L-glutamic acid dibutylamide and the like are disclosed. JP-A-2005-298388 (Patent Document 3) discloses an oily material in which dibutyl N-2-ethylhexanoylglutamate is used as a gelling agent in a liquid oil such as octyldodecanol, diisostearyl alcohol, and dimethylpolysiloxane. Foundations and oily lipsticks are disclosed. JP-A-2002-316971 (Patent Document 4) discloses N-2-ethylhexanoyl-L-glutamic acid dibutylamide, N-octanoyl-L-glutamic acid dibutylamide, N-decanoyl-L-glutamic acid dibutylamide, and these. And N-lauroyl-L-glutamic acid dibutylamide are disclosed as gelling agents for oily base, solid oil such as wax, paste oil such as lanolin, liquid oil such as isopropyl palmitate and N- Lipstick using 2-ethylhexanoylglutamic acid dibutylamide, liquid oil and antiperspirant gel stick using N-2-ethylhexanoylglutamic acid dibutylamide and N-lauroyl-L-glutamic acid dibutylamide as gelling agents Is disclosed. JP 2005-298635 (Patent Document 5) describes a lip gloss using paste oil such as derived paraffin, liquid oil such as octyldodecanol, and N-2-ethylhexanoylglutamic acid dibutylamide as a gelling agent. Is disclosed. In addition, International Publication WO 2004/105707 (Patent Document 6) discloses an oil gel composition in which N-acyl-L-glutamic acid dialkylamide is used as an oily base, a polyhydric alcohol not containing glycerin, and a gelling agent. Things are disclosed. Furthermore, Japanese Patent Application Laid-Open No. 2009-67947 (Patent Document 7) describes liquid oil, solid oil, surfactant, and gelling agent such as N-lauroyl-L-glutamic acid dibutylamide and N-2-ethylhexanoyl-L. -Stick-like hair treatment cosmetics using glutamic acid dibutylamide are disclosed.

  However, the lipstick disclosed in Patent Document 1 lacks versatility because it uses inulin fatty acid ss and a specific oily component. In this regard, in the oily solid cosmetics described in Patent Documents 2 to 6, N-2-ethylhexanoyl-L-glutamic acid dibutylamide and N-lauroyl-L-glutamic acid dibutylamide are used as gelling agents. Therefore, there are few restrictions on the oil component which can be used, and versatility is high.

  However, in the oily solid cosmetics described in Patent Documents 2 to 6, the wax is not used at all, or the amount of the lipstick described in Patent Document 4 in which the wax is used is about 15% and is liquid. Or a large amount of paste oil is used. For this reason, even if there is no perspiration at a temperature of about 40 ° C., which has been a standard for temperature stability evaluation, there is a strong possibility that the stability will be significantly lowered when the storage temperature is increased. When this happens, sweating cannot be avoided due to the storage state in summer, for example, by leaving it in a car. Also, in areas with high outside temperatures such as beaches and Southeast Asia, there was a possibility that sweating could not be avoided in the same way. In order to eliminate such a possibility, it is necessary to raise the temperature at which sweating can be suppressed as much as possible. In addition, the hair treatment cosmetic described in Patent Document 7 not only uses no wax, but also requires a different feeling from the use on the lips in order to care for the hair. Requires a different formulation design.

  On the other hand, it is conceivable to increase the temperature at which sweating can be suppressed by increasing the blending amount of solid oil, but as the blending amount of solid oil increases, the feeling of use, that is, the elongation becomes difficult, and it is difficult to obtain a uniform application. Or the gloss at the time of application may decrease. In this regard, in the lipstick disclosed in Patent Document 4, although the blending amount of the solid oil is small, sweating is not recognized even when stored at 40 ° C. However, in the lipstick described in Patent Document 4, only N-2-ethylhexanoylglutamic acid dibutylamide is used. The dissolution temperature of this N-2-ethylhexanoyl glutamic acid dibutylamide is 150 to 180 ° C., and if the temperature at the time of filling is not increased, the moldability is lowered and the production efficiency may be deteriorated.

  The present invention has been made in view of the above-mentioned background art, and provides an oily solid cosmetic with improved stability at a high temperature while maintaining a smooth feeling of use without reducing productivity. It is in.

  The oily solid cosmetic of the present invention comprises 5% to 50% solid oil, 20% to 65% liquid oil, 3% to 40% paste oil, and gelation. A solid oily cosmetic comprising a composition comprising N-lauroyl-L-glutamic acid dibutyramide (A) and N-2-ethylhexanoyl glutamic acid dibutylamide (B) as agents, wherein (A) and (B) The total amount of the composition is 0.3 mass% or more and 4.0 mass% or less, and the blend ratio of (A) and (B) (the blend amount of (A) / the blend amount of (B)) is as follows. It is a solid oily cosmetic that is 0.5 or more and 4.0 or less.

  According to the present invention, there is provided an oily solid cosmetic that has good filling properties in a filling container and has a smooth feeling in use, and has reduced sweating even at a storage temperature higher than that of a conventional oily solid cosmetic. Provided.

FIG. 1 is a diagram showing a change in the rising melting point when the mixing ratio of the A component and the B component is changed.

  The oily solid cosmetic composition of the present invention contains solid oil, liquid oil, and paste oil, and is gelled using a specific gelling agent to ensure proper smoothness for application to the skin while sweating. It is an oily solid cosmetic that pursues resistance to rustling, that is, does not easily sweat even at high temperatures.

  The oily solid cosmetic according to the present invention is a cosmetic that is solid at room temperature and that is adjusted with an oily component as a main component. As cosmetics, lipstick, lip gloss, lip balm and other lip cosmetics applied to the lips, makeup cosmetics such as teak color and oily foundation, applied to the skin such as cheeks and used for the purpose of protecting the skin. Oil-based protection cosmetics are exemplified. In addition, as the form of the oily solid cosmetic, there is a form filled in a container such as a stick or a metal dish (jar container), but any form may be used.

  The solid oil used in the present invention is an oily component that is solid at room temperature (25 ° C.). The component is a so-called wax or wax component, and examples thereof include paraffin wax, ceresin wax, microcrystalline wax, montan wax, polyethylene wax, carnauba wax, molasses, candelilla wax, beeswax, and whale wax. One or more solid oils are used.

  The blending amount of these solid oils is 5% or more and 50% or less in the composition, preferably 10% or more and 45% or less, and desirably 15% or more and 40% or less. When the blending amount of the solid oil exceeds 50%, the blending amount of the solid oil increases and not only a sufficient smoothness cannot be obtained, but also the filling processability when finished into a product is lowered. On the other hand, if it is less than 5%, the amount of liquid oil or paste oil in the composition becomes large, stability at high temperature cannot be obtained, and the object of the present invention cannot be achieved. In the present invention, “%” means “% by mass” unless otherwise specified.

  Further, hydrocarbon wax is preferably used as the solid oil of the present invention. The hydrocarbon wax is a solid oil different from the so-called narrow wax derived from esters of higher fatty acids and higher alcohols, such as paraffin wax, ceresin wax, microcrystalline wax, polyethylene wax, etc., and its main component is carbonized. This means a solid oil in the narrow sense consisting of hydrogen. Development of gel structure formed from N-lauroyl-L-glutamic acid dibutylamide (A) and N-2-ethylhexanoyl glutamic acid dibutylamide (B), which are gelling agents used in the present invention, and hydrocarbon wax crystals Since the development of the structure does not compete, the crystal of the hydrocarbon wax is sufficiently developed without being affected by the development of the gel structure. As a result, a high strength improvement effect can be obtained. Moreover, it is easy to melt at the time of application, and a smooth feeling of use is easily imparted. From such a viewpoint, the blending amount is preferably 50% or more by mass ratio with respect to the total solid oil. If it is less than 50%, sufficient solidification performance cannot be obtained and molding may not be possible. In addition, since the blending amount of other solid oil such as wax is larger than that of the hydrocarbon wax, there is a possibility that smooth coatability cannot be obtained.

  Liquid oil is an oily component that is liquid at room temperature (25 ° C.). Examples of the components include hydrocarbon oils such as liquid paraffin, squalane, polybutene, heavy liquid isoparaffin, ester oils such as cetyl ethylhexanoate, isotridecyl isononanoate, diisostearyl malate, triethylhexanoin, olive oil, castor oil, etc. Triglycerides, higher alcohols such as octyldodecanol, higher fatty acids such as isostearic acid, silicone oils such as methylpolysiloxane, highly polymerized methylpolysiloxane, methylcyclopolysiloxane, etc., one or more liquid oils Is used.

  The blending amount of the liquid oil is 20% or more and 65% or less, preferably 30% or more and 50% or less in the composition. If it is less than 20%, the amount of liquid oil is small, so that the gel structure by the gelling agent cannot be sufficiently formed, and sweating cannot be sufficiently suppressed. Moreover, since the component of solid oil increases, smoothness cannot be obtained. On the other hand, when the amount exceeds 65% by mass, the amount of liquid oil increases, leading to poor stability at a desired high temperature of about 45 ° C.

  As the liquid oil, it is preferable to use a high-viscosity hydrocarbon oil in the present invention. High viscosity hydrocarbon oils tend to have a strong gel structure. That is, since the high-viscosity hydrocarbon oil has low compatibility with the gelling agent, a gel structure is easily formed and sufficient gel strength can be obtained. Therefore, it becomes easy to obtain stability at high temperatures. The high-viscosity hydrocarbon oil in the present application is a hydrocarbon oil having a viscosity at 20 ° C. of 20 Pa.s (according to the method described in Examples) or higher. Examples of the high viscosity hydrocarbon oil include polybutene and hydrogenated polyisobutene. Examples of hydrogenated polyisobutene include volatile isoparaffin, light isoparaffin, light liquid isoparaffin, heavy isoparaffin, and liquid isoparaffin. “Pearl Reme 18”, “Pearl Ream 24”, “Pearl Ream 46” (each NOF Corporation) Commercial products such as company trade name), polybutene 100R, polybutene 300R, polybutene 2000H (manufactured by Idemitsu Petrochemical Co., Ltd.), and Nisseki Polybutene Grade HV1900 (manufactured by Nippon Oil Corporation) are used.

  From the above viewpoint, in the present invention, it is preferable that all of the liquid oil is a high-viscosity hydrocarbon oil. However, the blending amount is at least 2% by mass with respect to the total liquid oil, and the total composition is 0.04. % Or more and 65% or less is preferable. When the blending ratio is small with respect to the liquid oil, the gel strength tends to be weak. When the blending ratio is less than 2% with respect to the liquid oil, the effect of blending the high-viscosity hydrocarbon oil cannot be obtained.

  Paste oil is a semi-solid oily component at room temperature (25 ° C.). The semi-solid oily component is an oily component that is neither the solid oil nor the liquid oil among all oily components. Examples of the paste oil include petrolatum, dipentaerythritol fatty acid ester, dilauroyl glutamate (cholesteryl / behenyl / octyldodecyl), stearic acid hydrogenated castor oil, and the like.

  The blending amount of the paste oil is 3% or more and 40% or less. Paste oil adjusts the softness of oily solid cosmetics. If it is less than 3%, the effect of the paste oil is not sufficiently exhibited, and if it exceeds 40%, the strength is lowered.

  In the present invention, a gelling agent is used. In this invention, it is thought that the solid oil contained in solid cosmetics is hold | maintained firmly by forming a gel structure with a gelatinizer. In the present invention, both N-lauroyl-L-glutamic acid dibutylamide (component A) and N-2-ethylhexanoyl glutamic acid dibutylamide (component B) are used as gelling agents.

  The blending amount of gelling agent (total amount of component A and component B) is 0.3% or more and 4.0% or less in the composition. If the amount of the gelling agent is less than 0.3%, a sufficient gel cannot be formed, and if it exceeds 4.0%, the fluidity at the filling temperature of the oily solid cosmetic is lowered and the moldability is lowered. The composition becomes too stiff and the desired smoothness cannot be obtained.

  Also, the mixing ratio of the two components is a mass ratio in which A component: B component is in the range of 4: 1 to 1: 2, that is, (A component blending amount) / (B component blending amount) is 0.5 or more and 4.0. Preferably, (the amount of component A) / (the amount of component B) is 1.0 or more and 4.0 or less. Both components are known as gelling agents for oily components, and stability can be improved even with a single component, but using both together improves stability better than when using a single component. Suppression of perspiration can be achieved at 45 ° C. In addition, it is known that the dissolution temperature of N-2-ethylhexanoylglutamic acid dibutylamide as component B is 150 to 180 ° C. (see Patent Document 3). Decrease and increase liquidity. This allows melting at low temperatures. FIG. 1 is a diagram showing a change in the rising melting point when the mixing ratio of the A component and the B component is changed (see Example 1). According to this, the rising melting point is lowered by mixing the A component and the B component. For this reason, even when the component B is used, it is melted at a low temperature and can be easily filled into a jar container or a filling container for a stick (so-called molding mold). At this time, when the composition ratio of both is out of the above range, not only the improvement in sweating stability is not expected, but also a sufficient rise in melting point cannot be obtained, and the filling property into the container is deteriorated. Efficiency is also reduced.

  The filling into the filling container is usually performed at about 80 ° C. Considering this filling property, it is preferable to determine the blending amount of the gelling agent and the blending ratio of the A component and the B component so that the viscosity of the composition at 80 ° C. is 0.2 Pa.s or less. When the viscosity is higher than 0.2 Pa.s, the filling property into the molding die is deteriorated, and the occurrence rate of molding defects and the like is increased. In addition, the viscosity in this invention means what was measured by the method described in the Example of this application.

  From these viewpoints, so that a larger melting point drop is desired, the blending amount of the A component is equal to the blending amount of the B component, or the blending amount of the A component is increased, that is, (the blending amount of the A component) / It is more desirable to blend both components so that the blending amount of component B is 1.0 or more, preferably greater than 1.0 and 4.0 or less.

  A pigment may be mix | blended with the oil-based solid cosmetics of this invention. The pigment may be either an inorganic pigment or an organic pigment. Examples of the inorganic pigment include titanium oxide, iron oxide, chromium oxide, kangzhou, and gunjo. The organic pigment is oxidized into blue No. 1 aluminum lake, yellow No. 5 aluminum lake, and mica. Examples include so-called pearl pigments imparted with high surface reflectivity by coating titanium or the like. One or more pigments are blended in the composition. When pigments are blended, the blending amount is 0.0001% or more and 60% or less, preferably 50% or less. In addition, organic dyes such as red 202 may be blended.

  As long as the effects of the present invention are not impaired in the oily solid cosmetic of the present invention, in addition to the pigment, the oily component, and the gelling agent, surfactants, water-soluble polymers, alcohols, humectants, ultraviolet absorbers, Additive components used as oil-based solid cosmetics such as pH adjusters, antiseptics, antibacterial agents, antioxidants, and sequestering agents may be appropriately blended as necessary. In addition, the oily solid cosmetic of the present invention is a cosmetic mainly composed of an oily component and usually does not contain water. However, the cosmetics include water used for dissolving the above-mentioned additive components and moisture in raw materials. Depending on the properties of the raw material components used in the water, a small amount, specifically 0.5% or less, and at most 1.0% or less may be contained.

  The present invention will be described in more detail based on the following examples. However, it is needless to say that the following examples are merely examples, and the present invention is not limited to the following examples.

  First, the influence which the mixing ratio of A component and B component which is a gelatinizer has on the rising melting point was examined. The rising melting point was measured by mixing both gelling agents with octyldodecanol at the blending amounts shown in Table 1, and measuring the rising melting point. The results are shown in Table 1 and FIG. As a result, the rising melting point is lowered by mixing the A component and the B component, and when the mixing ratio of the A component and the B component is 2: 3 by mass, the rising melting point is 82 ° C., and the mixing ratio of the two is 1 It was understood that by increasing the A component to 75 ° C. in the case of 1, the rising melting point is lower than the rising melting point (68 ° C.) of the A component alone.

(Measurement method of rising melting point)
Each component was weighed as shown in Table 1, heated to 110 ° C. with stirring, and then sampled to a length of 1 cm in a hematocrit tube. Then, it was left to stand in an incubator at 20 ° C. for 4 hours, and the rising melting point was measured by the second melting point measuring method based on the cosmetic raw material.

  Based on the formulation example shown in Table 2, the lipstick which is an implementation product and a comparative product is prepared using the A component and the B component at the ratio shown in Table 3, and the rising melting point and high temperature stability (only sweating at 45 ° C.) Evaluation was performed based on the following method. Further, the viscosity at 80 ° C. was also measured in order to ensure pouring into the mold at around 85 ° C. The results are shown in Table 3. In addition, in the following prescription, Ajinomoto Co., Inc. product name "GP-1" was used as the A component for the gelling agent, and the product name "EB-21" manufactured by the same company was used as the B component. The viscosity of heavy liquid isoparaffin (trade name “Pearl Ream 46”) is 900 Pa.s, and the viscosity of polybutene (trade name “Nisseki Polybutene Grade HV1900” is 1000 Pa.s).

A. Evaluation of casting The components shown in Table 2 are dissolved by heating at a temperature of 85 ° C. or higher, and cast into a mold for stick molding at the temperature shown in Table 2. Then, after making it solidify with a -20 degreeC freezer and taking out from a type | mold, it was confirmed whether the surface has a crack and it has filled to the front-end | tip part of the type | mold. If the pouring property is poor, the mold is solidified at the time of touching the mold and then cracked without being mixed with the filled composition. When the pouring property was good, it was indicated by ◯, and a slight defect was observed, but when it was judged that there was no problem in production, Δ was indicated, and when it was defective, it was indicated by ×.

B. Viscosity measurement Each component was weighed in a stainless beaker for measurement, heated to 80 ° C. with stirring, and measured with a measuring rotor (viscosity measuring device: RION VISCOTESTER VT-04) that had been set to 80 ° C. in advance. .s) was measured.

C. Ascending melting point Weighed the ingredients shown in Table 2 and raised the temperature to 110 ° C while stirring, then sampled to a length of 1 cm in a hematocrit tube, left in an incubator at 20 ° C for 4 hours, and then the melting point of cosmetic raw material standards Measurement method The rising melting point was measured by the second method.

D. High temperature stability (1) Stability at 40 ° C or 45 ° C After molding, leave at room temperature for 1 week, then leave it in a constant temperature bath at 40 ° C or 45 ° C. The presence or absence of bending was confirmed. ◎ when no change is observed, ◯ when a slight change is observed, △ when a slight change is observed, and × when a considerable change is observed. It was.

  According to the results in Table 3, it was confirmed that good stability was obtained even at 45 ° C. by using only two kinds of gelling agents in the solid oil, liquid oil, and paste oil formulation systems. In consideration of this result and the result of Example 1, the sweating stability at 45 ° C. and 80 ° C. can be obtained by mixing the B component having an ascending melting point of about 64 ° C. with the B component that is about twice to 1/4 of that. It was understood that the ease of pouring was ensured.

  Next, lipsticks were prepared with reference to the results obtained in Table 3. In the formulation shown in Table 4, the gelling agent is used in the blending amount shown in Table 5, and Example 2 and the following description are described with respect to casting at 85 ° C., ascending melting point, high temperature stability, bending strength and feeling of use. Evaluation was performed based on the method. The results are shown in Table 5.

E. Folding strength Each lipstick obtained was left in a constant temperature bath at 20 ° C. and 37 ° C. for one day or longer, and then applied with a rheometer NRM-2002J made by Fudo Kogyo Co., Ltd. at a load of 1.5 cm from the base. The force (N) was measured, and this force was defined as the bending strength (N).

F. Feeling of use Several women with a makeup history of 10 years or more were used as panels, and each lipstick was evaluated for smoothness during application.

  As a result, it was understood that the rising melting point of the lipstick changes depending on the mixing ratio of the A component and the B component, and the ease of pouring, the sweating stability at 45 ° C, and the viscosity at 80 ° C change accordingly. According to this result, by using both the A component and the B component, the rising melting point of the lipstick composition was lowered, and at the same time, a lipstick having good temperature stability was obtained. In particular, when the blending ratio of the A component and the B component (the blending amount of A / the blending amount of B) is 1 or more, the pouring property at 85 ° C. and the viscosity at 80 ° C. become small, and a better filling property Obtained.

  Further, Comparative Example 5 was a gel that did not contain wax, and it was difficult to mold into a stick shape, and only a dosage form that could not be applied and could not measure the bending strength was obtained. In this respect, the lipstick of Comparative Example 6 using only N-2-ethylhexanoylglutamic acid dibutylamide as the B component as a gel agent had no sweat at 45 ° C. and had a smooth feeling of use. However, since only the component B is used, even if the composition is heated only to 85 ° C., a fluid uniform melt cannot be obtained, and there are many portions that are aggregated as solids. For this reason, if it is heated to about 105 ° C. and not sufficiently melted, it cannot be poured into the container, which requires not only extra heat energy, but also deformation due to shrinkage, etc. may occur during molding. It was inefficient.

Next, various oily solid cosmetics were prepared.
