Description

本発明は二層型粉末化粧料に関する。さらに詳しくは、粉末の再分散性に優れ、特にアルコール基剤の二層型粉末化粧料に関する。   The present invention relates to a two-layer powder cosmetic. More particularly, the present invention relates to an excellent powder redispersibility and particularly to an alcohol-based two-layer powder cosmetic.

化粧水に粉末を添加した化粧水として、例えばカーマインローションが知られている。これは化粧水の中に粉末を分散させた二層型粉末化粧料であり、使用時に粉末を分散させ、使用後には粉末が沈降するように設計されたものである。一般に、粉末が系の中で凝集する場合、アグリゲーションを起こせば再分散が困難となる。このように、二層型粉末化粧料の設計において、沈降したり凝集したりする粉末を再び分散させる再分散性(以下、再分散効果ともいう)は、極めて重要な技術的事項である。   For example, carmine lotion is known as a lotion obtained by adding powder to a lotion. This is a two-layer powder cosmetic in which powder is dispersed in a lotion, and is designed so that the powder is dispersed during use and the powder settles after use. In general, when powder aggregates in the system, re-dispersion becomes difficult if aggregation occurs. Thus, in the design of a two-layered powder cosmetic, redispersibility (hereinafter also referred to as a redispersion effect) for redispersing a settled or agglomerated powder is a very important technical matter.

Further, it is described that when antibacterial zeolite is blended in cosmetics as an alternative to organic preservatives, reaggregation and precipitation occur over time, and the antibacterial action is reduced accordingly. However, if a zeolite powder whose surface is treated with silicone is used, the redispersion effect is not sufficient and cannot be expected.

一方、特許文献3には、抗菌性ゼオライトの表面を特定のMQレジンで被覆すると、変色・汚着が少なく、使用感、防臭効果にも優れた皮膚外用剤が開示されている。   On the other hand, Patent Document 3 discloses an external preparation for skin which is less discolored / stained and excellent in feeling of use and deodorizing effect when the surface of antibacterial zeolite is coated with a specific MQ resin.

本発明者等は上述の観点に鑑み、二層型粉末化粧料における粉末の再分散効果について鋭意研究した結果、多くの化粧料原料成分の中から限定した特定成分を含有する二層型粉末化粧料が極めて優れた粉末の再分散効果を有することを見出し、本発明を完成するに至った。   In view of the above-mentioned viewpoints, the present inventors have conducted intensive research on the powder redispersion effect in the two-layer powder cosmetic, and as a result, the two-layer powder makeup containing a specific component limited from many cosmetic raw material components. It was found that the material has an extremely excellent powder redispersion effect, and the present invention has been completed.

本発明の目的は、粉末特にシリコーンで表面処理した抗菌性ゼオライトの粉末を配合した二層型の粉末化粧水において、使用時の粉末の再分散性を向上させることにある。   An object of the present invention is to improve the redispersibility of a powder in use in a two-layer powder lotion containing a powder, in particular, an antibacterial zeolite powder surface-treated with silicone.

さらに、本発明は、前記成分(c)の含有量が二層型粉末化粧料全量に対して50〜95質量%であることを特徴とする上記の二層型粉末化粧料を提供するものである。   Furthermore, the present invention provides the two-layer powder cosmetic described above, wherein the content of the component (c) is 50 to 95% by mass with respect to the total amount of the two-layer powder cosmetic. is there.

本発明の二層型粉末化粧料は極めて優れた粉末の再分散効果を有する。そして、本発明においては、表面をシリコーン処理した粉末を使用し、分散剤として分子量3500を超える(好ましくは分子量5000以上)ポリエーテル変性シリコーンを使用したとしても、好ましい再分散効果を発揮する。   The two-layered powder cosmetic of the present invention has an extremely excellent powder redispersion effect. And in this invention, even if it uses the powder which surface-treated silicone, and uses polyether modified silicone exceeding molecular weight 3500 (preferably molecular weight 5000 or more) as a dispersing agent, the preferable re-dispersion effect is exhibited.

特に本発明では、特定のMQレジンによりシリコーン処理された抗菌性ゼオライトの粉末が配合され、化粧料全量に対してエタノールを50〜95質量%含有するアルコール系基剤の二層型粉末化粧料において、再分散効果が優れている。なお、アルコール系基剤の二層型粉末化粧料では粉末の再分散性は困難である。   In particular, in the present invention, in an alcohol-based two-layer powder cosmetic containing an antibacterial zeolite powder silicone-treated with a specific MQ resin and containing 50 to 95% by mass of ethanol relative to the total amount of the cosmetic. The redispersion effect is excellent. In addition, it is difficult to redisperse the powder in the alcohol-based two-layer powder cosmetic.

(a)シリコーンで表面を疎水化処理した粉末
本発明において、シリコーン、粉末はそれぞれ限定されない。粉末配合化粧料に通常配合される粉末、粉末の表面をシリコーン処理するために通常使用されるシリコーンを使用することが出来る。シリコーンによる表面処理は常法に従う。
(A) Powder whose surface is hydrophobized with silicone In the present invention, silicone and powder are not limited respectively. It is possible to use a powder that is usually blended in a powder blend cosmetic and a silicone that is usually used to silicone-treat the surface of the powder. Surface treatment with silicone follows conventional methods.

本発明において、好ましく、また、本発明の意義を与える粉末は、抗菌性ゼオライトである。化粧料に通常配合される抗菌性ゼオライトであれば、その平均粒子系は問わない。但し、平均粒径が10μm以下であり、粒度分布において粒径が15μmを超えるものが20質量%以上含まれることが好ましい。   In the present invention, a powder that is preferable and that imparts the meaning of the present invention is an antibacterial zeolite. The average particle system is not limited as long as it is an antibacterial zeolite usually blended in cosmetics. However, it is preferable that the average particle size is 10 μm or less, and the particle size distribution contains 20% by mass or more of particles having a particle size exceeding 15 μm.

粉末の表面処理に用いるシリコーンは、下記平均式(1)で表されるMQレジンであることが好ましい。下記のMQレジンは公知のシリコーンであり特許文献3に記載されているものである。本発明では市販品を使用できる。

Figure 2009234994
(1)
式中、Rは一価炭化水素基であり、nは1〜5の数である。 The silicone used for the surface treatment of the powder is preferably an MQ resin represented by the following average formula (1). The following MQ resin is a known silicone and is described in Patent Document 3. In the present invention, a commercial product can be used.
Figure 2009234994
(1)
In the formula, R is a monovalent hydrocarbon group, and n is a number from 1 to 5.

MQレジンは、従来より撥水剤等としてファンデーション、アイクリーム、乳液、クリーム、サンスクリーン等の化粧品原料として単独で使用される他、化粧料用粉体の表面処理剤としても使用されている(特許第3378590号等)。   MQ resin is conventionally used alone as a cosmetic raw material for foundations, eye creams, emulsions, creams, sunscreens and the like as a water repellent, and also as a surface treatment agent for cosmetic powders ( Patent No. 3378590).

本発明に用いるMQレジンは、一般的には、(CH33SiCl、(CH33SiOSi(CH33、(CH33SiOH等のM単位を有するオルガノシロキサンと、水ガラス、オルソアルキルシリケート、アルキルポリシリケート等のシリケート類とを、有機溶媒中で、水、酸を添加して加水分解、縮合を行った後、中和、洗浄、溶媒除去等の工程を経て得られる。 The MQ resin used in the present invention is generally composed of an organosiloxane having M units such as (CH 3 ) 3 SiCl, (CH 3 ) 3 SiOSi (CH 3 ) 3 , (CH 3 ) 3 SiOH, and water glass. It can be obtained through the steps of neutralization, washing, solvent removal, etc. after hydrating and condensing silicates such as orthoalkyl silicate and alkylpolysilicate in an organic solvent by adding water and acid. .

本発明に用いるMQレジンのM/Qモル比は0.7〜1.0である。これは、M/Qモル比が1.0を超えるとMQレジンの吸着性が低下し、良好な被覆ができないことから十分な変色防止効果が得られないためであり、また0.7より小さくなると皮膜に好ましくないべたつきを生じるためである。   The M / Q molar ratio of the MQ resin used in the present invention is 0.7 to 1.0. This is because when the M / Q molar ratio exceeds 1.0, the adsorptivity of the MQ resin is lowered, and a satisfactory coating cannot be obtained, so that a sufficient discoloration preventing effect cannot be obtained. This is because an undesirable stickiness is generated in the film.

また、本発明に用いられるMQレジンの分子量は特に限定されないが、500〜10000の間にあることが好ましい。これは、分子量が500未満であると処理した粉末が凝集しやすいという欠点があり、10000を超えるとMQレジンの有機溶媒に対する溶解性が低下し粉体表面に均一に被覆できないという欠点があるためである。   The molecular weight of the MQ resin used in the present invention is not particularly limited, but is preferably between 500 and 10,000. This is because when the molecular weight is less than 500, the treated powder tends to aggregate, and when it exceeds 10,000, the solubility of the MQ resin in an organic solvent is lowered and the powder surface cannot be uniformly coated. It is.

上記成分(a)の粉末の配合量は、化粧料全量に対して0.1〜50質量%程度であるが、粉末を再分散させる本発明の意義と効果を考えるならば化粧料全量に対して1〜15質量%が好ましく、3〜7質量%がさらに好ましい。   The blending amount of the powder of the component (a) is about 0.1 to 50% by mass with respect to the total amount of the cosmetic, but considering the significance and effect of the present invention for redispersing the powder, the total amount of the cosmetic 1 to 15% by mass is preferable, and 3 to 7% by mass is more preferable.

(b)HLBが5以下のポリエーテル変性シリコーン
本発明においては化粧料に配合可能な市販品を使用できる。ポリエーテル変性シリコーンの分子量は3500を超える、好ましくは分子量5000以上のものを使用し、好ましい再分散効果を発揮する。
(B) Polyether-modified silicone having an HLB of 5 or less In the present invention, commercially available products that can be blended in cosmetics can be used. Polyether-modified silicone having a molecular weight of over 3500, preferably having a molecular weight of 5000 or more, exhibits a preferable redispersion effect.

(c)エタノール
エタノールの配合量は、化粧料全量に対して50〜95質量%であることが好ましい。アルコール系基剤の二層型粉末化粧料では粉末の再分散性は困難であるので、この点に本発明の意義がある。
(C) Ethanol It is preferable that the compounding quantity of ethanol is 50-95 mass% with respect to cosmetics whole quantity. Since the redispersibility of the powder is difficult in the alcohol-based two-layered powder cosmetic, the present invention is significant in this respect.

(d)グリセリン、1,3−ブチレングリコール、水からなる群から選択される1種又は2種以上の成分
本発明においては、これらの3つの成分のうち単独成分を配合しても効果は生じる。グリセリン及び/又は1,3−ブチレングリコールの配合量は、化粧料全量に対して5〜30質量%が好ましい。化粧料全量に対して30質量%を超えると使用性上べたつきを生じる。水の配合量は化粧料全量に対して3〜40質量%が好ましい。化粧料全量に対して40質量%を超えるとシリコーンで表面を疎水化した粉末の馴染みが悪くなる。
(D) One or two or more components selected from the group consisting of glycerin, 1,3-butylene glycol, and water In the present invention, an effect is produced even if a single component is blended among these three components. . As for the compounding quantity of glycerol and / or 1, 3- butylene glycol, 5-30 mass% is preferable with respect to cosmetics whole quantity. If it exceeds 30% by mass with respect to the total amount of the cosmetic, stickiness is caused on usability. As for the compounding quantity of water, 3-40 mass% is preferable with respect to cosmetics whole quantity. When the amount exceeds 40% by mass with respect to the total amount of the cosmetic, the familiarity of the powder whose surface has been hydrophobized with silicone becomes poor.

(e)パラフェノールスルホン酸亜鉛塩
本発明においては、粉末の再分散性の観点から、パラフェノールスルホン酸亜鉛塩を配合することが好ましい。パラフェノールスルホン酸亜鉛塩の配合量は化粧料全量に対して0.1〜1質量%であることが好ましい。
(E) Zinc paraphenolsulfonic acid salt In the present invention, it is preferable to blend zinc paraphenolsulfonic acid salt from the viewpoint of powder redispersibility. It is preferable that the compounding quantity of paraphenolsulfonic acid zinc salt is 0.1-1 mass% with respect to cosmetics whole quantity.

本発明の二層型粉末化粧料には上記した必須構成成分の他に通常化粧品に用いられる他の成分、例えば、液体油脂、固体油脂、ロウ、炭化水素油、高級脂肪酸、高級アルコール、エステル油、シリコーン油、アニオン界面活性剤、カチオン界面活性剤、両性界面活性剤、非イオン界面活性剤、保湿剤、水溶性高分子、増粘剤、紫外線吸収剤、金属イオン封鎖剤、多価アルコール、pH調整剤、皮膚栄養剤、ビタミン、酸化防止剤、酸化防止助剤、香料等を必要に応じて適宜配合し、常法により製造することが出来る。
また、本発明では実質的に上記必須成分のみからなる二層型粉末化粧料が好ましい。
なお、二層型粉末化粧料とは、粉末と液体とが二層になり得る粉末配合の液体化粧料において、使用時に容器を振ることにより粉末の再分散を必要とする化粧料を意味する。
In addition to the essential constituents described above, the two-layer powder cosmetic of the present invention has other components that are usually used in cosmetics, such as liquid fats, solid fats, waxes, hydrocarbon oils, higher fatty acids, higher alcohols, ester oils. , Silicone oil, anionic surfactant, cationic surfactant, amphoteric surfactant, nonionic surfactant, moisturizer, water-soluble polymer, thickener, ultraviolet absorber, sequestering agent, polyhydric alcohol, A pH adjuster, skin nutrients, vitamins, antioxidants, antioxidant aids, fragrances, and the like can be appropriately blended as necessary, and can be produced by conventional methods.
Moreover, in this invention, the two-layer type powder cosmetics which consist only of the said essential component are preferable.
Note that the two-layered powder cosmetic refers to a cosmetic that requires powder redispersion by shaking the container at the time of use in a liquid cosmetic containing a powder and a liquid that can be in two layers.
