- the present invention relates to an improvement in solid cosmetics for lips, especially solid cosmetics for lips that are excellent in secondary adhesion-less effect, long lasting makeup, and good adhesion.
- Patent Documents 1 to 4 hydrogenated polyisobutene that adheres to the lips and organic silicone oil that has low compatibility with the hydrogenated polyisobutene at room temperature are used. discloses a solid lip cosmetic that separates hydrogenated polyisobutene and organic silicone oil by
- the hydrogenated polyisobutene adheres to the lips during use, and the organic silicone oil layer forms a film on the hydrogenated polyisobutene layer. Since this organic silicone oil is colorless and transparent, even if it is transferred to a cup or the like, stains are inconspicuous, and the effect of preventing secondary adhesion is exhibited.
- Patent Document 5 together with a specific amount of phenyl-modified silicone, a high-viscosity non-volatile ester oil that does not show compatibility with the phenyl-modified silicone even at high temperatures, a dextrin fatty acid ester, and a volatile hydrocarbon are combined.
- an oil-in-oil lip cosmetic that is non-sticky and has an excellent secondary adhesion-less effect is disclosed.
- problems such as stickiness and deterioration of the secondary adhesion resistance effect depending on the oil content selected.
- the present invention has been devised in view of the above-mentioned problems of the prior art, and aims to provide a solid cosmetic for lips that has an excellent effect of preventing secondary adhesion, has excellent makeup longevity, and has an excellent adhesion feeling.
- a copolymer containing a dimer acid ester and/or a dimer acid ester was applied to the lips as an oil component (adhesive oil component) that adheres to the lip side.
- the solid cosmetic for lips includes the following five points.
- (1) Contains the following components (A) to (C).
- (A) (a1) a copolymer containing a dimer acid ester and/or (a2) 15 to 50% by mass of a dimer acid ester
- (B) phenyl-modified silicone compatible with (A) at 100 ° C. 20 to 70% by mass
- the total amount of components (A), (B) and (C) preferably accounts for 80 to 100% by mass of the entire cosmetic composition.
- the cosmetic further contains (D) a coloring material.
- the (B) component separates from the (A) component at 25°C.
- component (B) In the above cosmetics, the viscosity of component (B) is 300 mPa ⁇ s or less at room temperature. (3) In the cosmetic, the ratio of component (A) to component (B) is 1:0.5 to 1:4. (4) In the above cosmetic, the component (A) comprises one or two selected from (polyglyceryl-2 isostearate/dimer dilinoleic acid) copolymer and dimer dilinoleyl dimer dilinoleate. do. (5) The above cosmetic is characterized in that (B) contains one or two selected from diphenylsiloxyphenyltrimethicone and trimethylpentaphenyltrisiloxane.
- the solid cosmetic for lips according to the present invention comprises (A) (a1) a copolymer containing a dimer acid ester and/or (a2) a dimer acid ester, (B) a phenyl-modified silicone that separates from (A) at room temperature, By blending a specific amount of (C) wax, the effect of preventing secondary adhesion is obtained, a feeling of adhesion is obtained, and the make-up lasts well.
- the solid cosmetic for lips according to the present invention comprises (A) (a1) a copolymer containing a dimer acid ester and/or (a2) a dimer acid ester, (B) a phenyl-modified silicone that separates from (A) at room temperature, (C) wax.
- A (a1) a copolymer containing a dimer acid ester and/or (a2) a dimer acid ester
- B a phenyl-modified silicone that separates from (A) at room temperature
- C wax
- the amount of component (A) to be blended is preferably 15 to 50% by mass with respect to the total cosmetic composition. It is preferably 20 to 40% by mass, more preferably 25 to 35% by mass, from the viewpoints of adhesion to the lips and durability of the cosmetic effect.
- Phenyl-modified silicone preferably has a viscosity of 300 mPa ⁇ s or less. More preferably, it is 200 mPa ⁇ s or less. In the present invention, the viscosity is determined at 25° C. by spindle No. It was measured with a Brookfield viscometer TVB-10 (manufactured by Yamato Co., Ltd.) at M1 and 100 rpm. When mixed with (A) (a1) copolymer containing dimer acid ester and/or (a2) dimer acid ester at 100°C, they are compatible and separate at 25°C.
- the presence or absence of "compatibility” is defined as the following conditions.
- a transparent state at 100° C. with no boundary visible, that is, a “non-separated state” was defined as compatible.
- Phenyl-modified silicones include, for example, trimethylpentaphenyltrisiloxane, diphenyldimethicone, diphenylsiloxyphenyltrimethicone, and phenyltrimethicone.
- trimethylpentaphenyltrisiloxane and diphenylsiloxyphenyltrimethicone are preferable.
- Commercial products of trimethylpentaphenyltrisiloxane include, for example, methylphenyl silicone PH-1555 (manufactured by Dow Corning Toray Co., Ltd.).
- diphenylsiloxyphenyl trimethicone examples include, for example, Silicone KF56 (manufactured by Shin-Etsu Chemical Co., Ltd.).
- the blending amount of component (B) is 20 to 70% by mass based on the total cosmetic composition. It is preferably 30 to 55% by mass, more preferably 35 to 50% by mass. If the blending amount of component (B) is less than 20% by mass, it becomes difficult to separate during application, and the effect of preventing secondary adhesion is difficult to appear. On the other hand, if it exceeds 70% by mass, the amount of other components to be blended is reduced, and the effect of preventing secondary adhesion is difficult to appear.
- the viscosity of component (B) is 300 mPa ⁇ s or less. If the viscosity exceeds 300 mPa ⁇ s, it will not be compatible with the adhesive oil component at high temperatures, so the (C) wax will not dissolve uniformly, making molding impossible.
- Ratio of Component (A) to Component (B) The compounding ratio of component (A) to component (B) is preferably 1:0.5 to 1:4. More preferably, it is 1:0.8 to 1:3.5. Within this range, components (A) and (B) dissolve at 100°C and separate at 25°C.

- (C) wax used in the present invention includes, for example, carnauba wax, candelilla wax, polyethylene wax, beeswax, ceresin, microcrystalline wax, solid paraffin, Japanese wax, beeswax, polyethylene wax, and the like.
- the blending amount of component (C) is preferably 5 to 15% by mass based on the total amount of the cosmetic. More preferably, it is 7 to 12% by mass. If the blending amount of component (C) is less than 5% by mass, it may be difficult to solidify.
- the solid cosmetic composition for lips of the present invention can contain, as optional components, components commonly used in solid cosmetic compositions for lips, in addition to the above essential components (A) to (C). It is also preferable to blend (D) a coloring material into the solid cosmetic for lips of the present invention. As the colorant, those commonly used in solid cosmetics for lips can be blended.
- the coloring material (D) may be a coloring material that is commonly used in cosmetics, and may be in the form of a powder or in the form of a lake (in which oil is kneaded). It may be an inorganic pigment, an organic pigment, or a pearlescent agent. At this time, it is desirable that the colorant dissolves or disperses in the component (A) that adheres to the lips, but does not dissolve or disperse in the component (B) that is exuding oil. This is because if the coloring material is also dispersed in the component (B), the secondary adhesion resistance effect is lowered.
- coloring materials include inorganic white pigments (titanium dioxide, zinc oxide), inorganic red pigments (iron oxide (red iron oxide), iron titanate), inorganic brown pigments ( ⁇ -iron oxide), and inorganic yellow pigments.
- inorganic black pigments black iron oxide, carbon, low order titanium oxide
- inorganic purple pigments mango violet, cobalt violet

- the amount of component (D) to be blended is preferably 0.1 to 15% by mass relative to the total cosmetic composition. More preferably, it is 4 to 10% by mass. If the amount of the component (D) is less than 0.1% by mass, it may be difficult to feel the secondary adhesion resistance effect. On the other hand, if it exceeds 15% by mass, the amount of components (A) to (C) to be blended is relatively small, which may reduce the effect of preventing secondary adhesion.
- the solid cosmetic composition for lips of the present invention can be produced without so-called "binder oil".
- the binder oil is for making the adhesion oil and the oozing oil compatibilize at a high temperature.
- the binder oil may be absent or may be included.
- Binder oils include diisostearyl malate, neopentyl glycol dicaprate, triethylhexanoin, pentaerythrityl tetraethylhexanoate, and tri(caprylic/capric) glyceryl.
- a suitable blending amount is 0 to 20% by mass.
- the solid cosmetic for lips of the present invention may contain oils, powders, polymer compounds, moisturizing agents, fragrances, antioxidants, preservatives, and cosmetic agents other than those used in ordinary solid cosmetic for lips. Ingredients and the like can be appropriately blended within a range that does not impair the effects of the present invention.
- the amount of powder added in the present invention is preferably 30% by mass or less relative to the cosmetic. More preferably, it is 20% by mass or less. If the amount of the powder to be added exceeds 30% by mass, the amount of the components (A) to (C) to be blended becomes relatively small, which may reduce the secondary adhesion resistance effect.
- Powders include spherical powders, plate-like powders, coloring materials, and the like. Examples of spherical powder include polymethyl methacrylate, organopolysiloxane elastomer, polystyrene, polyamide resin (nylon), polyethylene, copolymer of styrene and acrylic acid, benzoguanamine resin, polytetrafluoroethylene, and silicone resin.

- Powders subjected to hydrophilization may be used as powders of pigments, pearlescent agents, lame agents, and the like.
- As the hydrophilized powder one that has undergone a hydrophilization treatment commonly known in the art can be used. Both organic and inorganic treatments can be used for hydrophilization.
- hydrophilizing agents include, but are not limited to, polyhydric alcohols, polysaccharides, water-soluble polymers, metal alkoxides, and water glass.
- the solid cosmetic for lips of the present invention is composed so that it does not separate in all the manufacturing steps and is in a homogeneous one-phase state.
- the solid cosmetic composition for lips of the present invention can be applied to lipstick, lip gloss, lip base for foundation, lipstick overcoat, lip balm, and the like.
- a solid stick lipstick is particularly preferred.
- the present invention will be described in more detail below with reference to examples, but the present invention is not limited by these. Unless otherwise specified, the blending amount is shown in % by mass.
- the present inventors produced a sample (solid lipstick) having the composition shown in the table by a conventional method. Then, each sample was evaluated based on the following evaluation criteria.
- (B) does not satisfy the condition of "separating from component (A) at 25°C and being compatible with component (A) at 100°C.” It can be seen that when phenyl-modified silicone is used, moldability is not excellent. It is also suggested that the viscosity of the phenyl-modified silicone as component (B) is preferably 300 mPa ⁇ s or less. More preferably, it is 200 mPa ⁇ s or less.

(5)上記化粧料において、(B)がジフェニルシロキシフェニルトリメチコン、トリメチルペンタフェニルトリシロキサンから選択される1種または2種を含むことを特徴とする。
以下、各成分について詳細に説明する。
(a1)ダイマー酸エステルを含む共重合体は、高粘度非揮発性エステル油であり、二次付着レスの効果を高めるために(B)フェニル変性シリコーンと100℃で相溶し、25℃で分離するものを選択する。(a2)ダイマー酸のエステルは植物系油脂を原料とするC18不飽和脂肪酸の二量化によって生成されたC36ジカルボン酸の二塩基酸を主成分とし、一塩基酸、三塩基酸を含有する液状脂肪酸のエステルである。
唇への密着性及び、化粧効果の持続性の観点から好ましくは20~40質量%であり、さらに好ましくは25~35質量%である。
(B)フェニル変性シリコーンは、粘度が300mPa・s以下であることが好ましい。
さらに好ましくは200mPa・s以下である。なお、本発明において粘度は、25℃において、spindle No.M1、100rpmにてB型粘度計TVB-10(ヤマト株式会社製)で測定したものである。
また、100℃で(A)(a1)ダイマー酸エステルを含む共重合体及び/又は(a2)ダイマー酸のエステルと混合した時に相溶し、25℃では分離するものである。
本発明において、「分離」の有無は、以下の条件で測定された。
(測定条件)
(A)成分と(B)成分を(A):(B)=1:1(質量比)で用いて、100℃に加温し、攪拌混合し、次いで静置し、混合物が25℃になった時に、境界が均一に2層に分離しているものを「分離する」とし、境界がなく透明な状態を「分離しない」とする。目視できる境界がなく不透明な状態は白濁とする。
100℃で境界を目視出来ず透明な状態、すなわち「分離していない状態」を相溶と規定した。
トリメチルペンタフェニルトリシロキサンは、市販品としては、例えばメチルフェニルシリコーンPH-1555(東レ・ダウコーニング社製)が挙げられる。
好ましくは30~55質量%であり、さらに好ましくは35~50質量%である。
(B)成分の配合量が20質量%未満では、塗布時に分離しにくくなり、二次付着レス効果が現れにくい。また、70質量%を超えると、他成分の配合量が減ってしまい、二次付着レス効果が現れにくい。
粘度が300mPa・sを超えると高温で密着油分と相溶しなくなるため、(C)ワックスが均一に溶解せず、成型不能となる。
(A)成分と(B)成分の配合比としては、1:0.5~1:4が好適である。さらに好ましくは1:0.8~1:3.5である。この範囲内であると(A)成分、(B)成分は100℃で溶解し、25℃では分離する。
本発明の唇用固形化粧料に配合される(C)ワックスとしては、通常化粧料に配合されるものであれば、特に限定されない。
本発明に用いられる(C)ワックスは、高温では(A)成分、(B)成分と相溶性があり、常温においては分離するものが好ましい。
さらに好ましくは7~12質量%である。(C)成分の配合量が5質量%以下だと固化しづらい場合があり、15質量%を超えると、伸びづらく、ツヤがなくなることがある。
本発明の唇用固形化粧料には(D)色材を配合することも好適である。色材としては、通常唇用固形化粧料に用いられるものを配合することができる。
この時、色材は唇に密着する(A)成分に溶解もしくは分散し、染み出し油分としての(B)成分には溶解・分散しないことが望ましい。色材が(B)成分にも分散すると二次付着レス効果が低下するからである。
色材としては、例えば、無機白色系顔料(二酸化チタン、酸化亜鉛)、無機赤色系顔料(酸化鉄(ベンガラ)、チタン酸鉄)、無機褐色系顔料(γ-酸化鉄)、無機黄色系顔料(黄酸化鉄、黄土)、無機黒色系顔料(黒酸化鉄、カーボン、低次酸化チタン)、無機紫色系顔料(マンゴバイオレット、コバルトバイオレット)、無機緑色系顔料(酸化クロム、水酸化クロム、チタン酸コバルト)、無機青色系顔料(群青、紺青)、パール顔料(酸化チタン被覆マイカ、酸化チタン被覆オキシ塩化ビスマス、酸化チタン被覆タルク、着色酸化チタン被覆マイカ、オキシ塩化ビスマス、魚鱗箔)、金属粉末顔料(アルミニウムパウダ一、カッパーパウダー)、有機顔料(赤色202号、赤色205号、赤色220号、赤色228号、赤色405号、橙色203号、橙色204号、黄色205号、黄色40号、青色404号)、ジルコニウム、バリウム、アルミニウムレーキの有機顔料(赤色3号、赤色104号、赤色227号、赤色401号、橙色205号、黄色4号、黄色20号、緑色3号、青色1号)、天然色素(クロロフィル、カルチノイド系(β-カロチン)、カルサミン、コチニール、カルコン、クルクミン、ベタニン、フラボノール、フラボン、アントシアニジン、アントラキノン、ナフトキノン)、機能性顔料(窒化ホウ素、フォトクロミック顔料、合成フッ素金雲母、鉄含有合成フッ素金雲母、微粒子複合粉体(ハイブリッドファインパウダー))等が挙げられる。
さらに好ましくは4~10質量%である。(D)成分の配合量が0.1質量%未満では、二次付着レス効果を感じにくい場合がある。また、15質量%を超えると、相対的に(A)~(C)成分の配合量が少なくなってしまうため、二次付着レスの効果を低下させてしまう場合がある。
つなぎ油分としては、リンゴ酸ジイソステアリル、ジカプリン酸ネオペンチルグリコール、トリエチルヘキサノイン、テトラエチルヘキサン酸ペンタエリスリチル、トリ(カプリル酸/カプリン酸)グリセリル等が挙げられる。好適な配合量は0~20質量%である。
