Description

本発明は化粧料に関し、更に詳細には、メークアップ化粧料や紫外線防護化粧料に有用な酸化亜鉛を含有する水中油乳化剤形の化粧料に関する。   The present invention relates to a cosmetic, and more particularly, to an oil-in-water emulsifier type cosmetic containing zinc oxide useful for makeup cosmetics and UV protective cosmetics.

酸化亜鉛はUV−Aにも吸収極大を有する化粧料用の素材であり、UV−Aの生体に対する影響が強く懸念される今日、紫外線より、生体を防護するためには必要欠くべからざる素材である。紫外線防護化粧料などに於いては、酸化亜鉛は、所望によりその表面をハイドロジェンメチルポリシロキサン焼付等で疎水化処理し、二酸化チタン等ともに配合されている。又、紫外線防護化粧料に於いては、均一な化粧膜を形成させることが必要であることから、乳化剤形を用いることが多いが、酸化亜鉛も二酸化チタンも非常に比重が大きく、これを安定に分散させるためには、分散媒の構造をしっかりとしたもにする必要があり、この様な粘度構造のしっかりした剤形として、油中水乳化剤形が選択される場合が多かった。水中油乳化剤形としては、サクシノグルカンなどの高分子を使用して構造を持たせる方法(例えば、特許文献1を参照)や、分岐型ポリエーテル変性シリコーンなどのような極めて特殊な界面活性剤を使用する方法(例えば、特許文献2を参照)などが散見する程度であった。この様な剤形に於いても、当座の安定性は確保できても、過酷な保存条件や、長期の保存条件では十分に安定であるとは言えないのが現状であった。特に、容器として樹脂製のものを選択した場合、樹脂表面が親油性であることから、エマルションに対しては油性成分を誘引する親和性を発揮し、エマルションの形態の維持にとっては過酷な条件となる場合が存し、この様な結果、離水現象を起こす場合も存した。その一方、使用をする時期が夏を中心とすることから、紫外線防護化粧料としては、使用感などの面から、油ぽっく、のびの重い油中水乳化剤形よりは、水中油乳化剤形の方が好ましいことは明らかであり、製剤の安定性からやむなく油中水乳化剤形を選択しているのが現状であると言える。   Zinc oxide is a material for cosmetics that has a maximum absorption even in UV-A, and UV-A is a material that is indispensable to protect the living body from ultraviolet rays today. is there. In UV protective cosmetics and the like, the surface of zinc oxide is hydrophobized by baking with hydrogen methylpolysiloxane, if desired, and blended with titanium dioxide or the like. In UV protective cosmetics, since it is necessary to form a uniform cosmetic film, the emulsifier type is often used, but both zinc oxide and titanium dioxide have very high specific gravity and are stable. In order to make it disperse | distribute to, it is necessary to make the structure of a dispersion medium firm, and the water-in-oil emulsifier form was often selected as a firm dosage form of such a viscosity structure. As the oil-in-water emulsifier form, a very special surfactant such as a method of giving a structure using a polymer such as succinoglucan (see, for example, Patent Document 1) or a branched polyether-modified silicone. The method of using (for example, refer to Patent Document 2) and the like are only occasionally seen. Even in such a dosage form, even if the current stability can be secured, it cannot be said that it is sufficiently stable under severe storage conditions or long-term storage conditions. In particular, when a resin-made container is selected, the resin surface is lipophilic, so it exhibits an affinity for attracting oily components to the emulsion, and severe conditions for maintaining the emulsion form There was a case where water separation occurred as a result. On the other hand, since the period of use is mainly in summer, as a UV protection cosmetic, from the viewpoint of feeling of use etc., oil-in-water emulsifier type rather than oil-pox and heavy oil-in-water emulsifier type It is clear that this is preferable, and it can be said that the water-in-oil emulsifier form is unavoidably selected from the stability of the preparation.

一方、乳化剤形に於いて、酸化亜鉛とクエン酸とを共存させる技術は、油中水乳化剤形に於いては知られている(例えば、特許文献3を参照)が、水中油乳化剤形に於いては、全く知られておらず、この様な構成を取ることにより、安定性、特に、樹脂容器に充填した場合の安定性を向上せしめる効果が存することも全く知られていなかった。   On the other hand, the technique of making zinc oxide and citric acid coexist in the emulsifier form is known for the water-in-oil emulsifier form (see, for example, Patent Document 3), but in the oil-in-water emulsifier form. However, it has not been known at all that there is an effect of improving the stability, in particular, the stability when filled in a resin container, by adopting such a configuration.

(1)本発明の化粧料の必須成分である酸化亜鉛
本発明の化粧料は、水中油乳化剤形の化粧料であって、表面を疎水化処理されていても良い酸化亜鉛1〜10質量%、より好ましくは、3〜8質量%を必須成分として、含有することを特徴とする。ここで、表面の疎水化処理としては、通常化粧料の粉体で為されているものであれば特段の限定はなく使用することができ、例えば、ハイドロジェンメチルポリシロキサン焼付、ジメチルポリシロキサン焼付、パーフルオロアルキルシリル化剤処理、脂肪酸アルミニウム石鹸被覆処理、ポリエチレン被覆処理、レシチン被覆処理、アシルグルタミン酸アルミニウム被覆処理などが例示できる。これらの表面処理を為されたもの或いは表面処理を行っていないものの中では、予め、ハイドロジェンメチルポリシロキサン焼付処理を行うことが好ましい。この場合、処理に用いられるハイドロジェンメチルポリシロキサンの量は、酸化亜鉛量に対して、1〜20質量%が好ましく、2〜10質量%がより好ましい。他の疎水化処理においても、処理量は同様である。この様な、表面を疎水化処理されていても良い酸化亜鉛で化粧料原料用のものとしては、例えば、FINEX−25、FINEX−50、FINEX−75(以上、堺化学工業(株));MZ300シリーズ、MZ500シリーズ、MZ700シリーズ(以上、テイカ(株));ZnO−350(住友大阪セメント(株))などの市販品が挙げられる。かかる市販品の内、特に好ましいものとしては、ハイドロジェンメチルポリシロキサン5質量%焼付の「微粒子酸化亜鉛MZ−503S」(テイカ(株)製)が例示できる。かかる成分は、本発明の化粧料では、通常の化粧料での配合目的と同様の機能を発揮する。即ち、メークアップ化粧料に於いては、隠蔽効果と紫外線防護効果とを発揮し、紫外線防護化粧料に於いては、紫外線防護効果を発揮する。前記含有量は、この様な効果を発揮できる為に必要な量であり、上限値は、水中油乳化剤形を維持する上での限度量である。
(1) Zinc oxide as an essential component of the cosmetic of the present invention The cosmetic of the present invention is a cosmetic in the form of an oil-in-water emulsifier, and the surface of the zinc oxide whose surface may be hydrophobized is 1 to 10% by mass. More preferably, it contains 3 to 8% by mass as an essential component. Here, the surface hydrophobization treatment can be used without particular limitation as long as it is usually made of cosmetic powders. For example, hydrogen methylpolysiloxane baking, dimethylpolysiloxane baking, etc. Examples thereof include perfluoroalkylsilylating agent treatment, fatty acid aluminum soap coating treatment, polyethylene coating treatment, lecithin coating treatment, and acyl glutamate aluminum coating treatment. Among those subjected to surface treatment or those not subjected to surface treatment, it is preferable to perform a hydrogen methylpolysiloxane baking treatment in advance. In this case, the amount of hydrogen methylpolysiloxane used for the treatment is preferably 1 to 20% by mass, and more preferably 2 to 10% by mass with respect to the amount of zinc oxide. The processing amount is the same in other hydrophobizing treatments. Examples of such zinc oxide whose surface may be hydrophobized and used for cosmetic materials include FINEX-25, FINEX-50, FINEX-75 (above, Sakai Chemical Industry Co., Ltd.); Commercial products such as MZ300 series, MZ500 series, MZ700 series (above, Teika Co., Ltd.); ZnO-350 (Sumitomo Osaka Cement Co., Ltd.) can be mentioned. Among such commercially available products, “fine particle zinc oxide MZ-503S” (manufactured by Teika Co., Ltd.), which is baked with 5% by mass of hydrogenmethylpolysiloxane, is particularly preferable. In the cosmetic of the present invention, such a component exhibits the same function as the purpose of blending in a normal cosmetic. That is, the makeup cosmetic exhibits a concealing effect and an ultraviolet protective effect, and the ultraviolet protective cosmetic exhibits an ultraviolet protective effect. The content is an amount necessary for exhibiting such an effect, and the upper limit value is a limit amount for maintaining the oil-in-water emulsifier form.

(2)本発明の化粧料の必須成分であるクエン酸
本発明の化粧料は、必須成分としてクエン酸乃至はその塩を0.1〜1質量%、より好ましくは0.2〜0.5質量%含有することを特徴とする。本発明の化粧料に於いて、かかる成分は、本発明の化粧料の過酷な条件での安定性を向上させる作用を有する。前記過酷な条件としては、表面の親油性の性質によって、化粧料より、油性成分を誘引し、水性成分を剤形より脱離させる、言い換えれば、水相成分を分離させる条件が例示できる。即ち、樹脂容器などの化粧料と接する面が樹脂であるような容器に充填された場合である。この様な場合に於いても、クエン酸を前記の量範囲含有することにより、この様な水相の分離を防ぐことができる。尚、この様な現象は、連続相が水相である水中油乳化剤形にのみ見られる現象であり、油中水乳化剤形には観察されにくい。本発明に於いて、水中油乳化剤形とは、連続相が水相である乳化剤形の総称を意味し、水中油中水などの複合乳化剤形であっても、連続相として水相が存在する限り、水中油乳化剤形に含まれる。
(2) Citric acid which is an essential component of the cosmetic of the present invention The cosmetic of the present invention has 0.1 to 1% by mass, more preferably 0.2 to 0.5% of citric acid or a salt thereof as an essential component. It is characterized by containing mass%. In the cosmetic of the present invention, such a component has an effect of improving the stability of the cosmetic of the present invention under severe conditions. Examples of the harsh conditions include conditions for attracting oily components from cosmetics and desorbing aqueous components from the dosage form, in other words, separating the aqueous phase components, depending on the lipophilic nature of the surface. That is, it is a case where a container such as a resin container that comes into contact with cosmetics is filled with a resin. Even in such a case, it is possible to prevent such separation of the aqueous phase by containing citric acid in the aforementioned amount range. Such a phenomenon is a phenomenon observed only in the oil-in-water emulsifier form in which the continuous phase is an aqueous phase, and is hardly observed in the water-in-oil emulsifier form. In the present invention, the oil-in-water emulsifier form is a general term for an emulsifier form in which the continuous phase is an aqueous phase, and a water phase exists as a continuous phase even in a complex emulsifier form such as water-in-oil-in-water. As long as it is included in the oil-in-water emulsifier form.

(3)本発明の化粧料
本発明の化粧料は、前記必須成分を含有し、水中油乳化剤形であることを特徴とする。本発明の化粧料に於いては、水中油乳化剤形を形成することを要件とすることから、界面活性剤を含有する必要が存する。かかる界面活性剤としては、非イオン界面活性剤のみを用いることが好ましい。これは、アニオン界面活性剤、取り分け脂肪酸石鹸、カチオン界面活性剤、両性界面活性剤は、酸化亜鉛との相互作用を有し、凝集や分離など、安定性を損なう場合が少なくないからである。又、非イオン界面活性剤としては、非イオン界面活性剤の中でも、強固な乳化構造を形成するものが好ましく、具体的には、脂肪酸モノグリセライド、ポリグリセリン脂肪酸エステル、ポリオキシエチレン脂肪酸エステル、ソルビタン脂肪酸エステル、(グリセリン/オキシブチレン)コポリマーアルキル及び蔗糖脂肪酸エステルから選択される1種乃至は2種以上が特に好ましく例示できる。最も好ましい形態は、これら全てを含み、これらの含有質量比を調整し、適切な親油性・親水性バランス(HLB)を得たものである。これらの含有量は、総量で5〜10質量%が好ましく、6〜9質量%がより好ましい。
(3) Cosmetics of this invention The cosmetics of this invention contain the said essential component, It is an oil-in-water emulsifier form, It is characterized by the above-mentioned. In the cosmetic of the present invention, since it is required to form an oil-in-water emulsifier form, it is necessary to contain a surfactant. As such a surfactant, it is preferable to use only a nonionic surfactant. This is because anionic surfactants, especially fatty acid soaps, cationic surfactants, and amphoteric surfactants have an interaction with zinc oxide and often impair stability such as aggregation and separation. The nonionic surfactant is preferably a nonionic surfactant that forms a strong emulsified structure. Specifically, fatty acid monoglyceride, polyglycerin fatty acid ester, polyoxyethylene fatty acid ester, sorbitan fatty acid One or more selected from esters, (glycerin / oxybutylene) copolymer alkyl and sucrose fatty acid esters are particularly preferred. The most preferable form includes all of these, and the content ratio of these is adjusted to obtain an appropriate lipophilic / hydrophilic balance (HLB).

以下に、実施例を挙げて、本発明について更に詳細に説明を加えるが、本発明がかかる実施例にのみ、限定されないことは言うまでもない。   Hereinafter, the present invention will be described in more detail with reference to examples, but it is needless to say that the present invention is not limited to such examples.

以下に示す処方に従って、本発明の化粧料である紫外線防護化粧料を製造した。即ち、ロ、ハの成分を予め80℃に加熱しておき、別途イの成分を混合し、コボールミルで分散均一化して作成したペーストをロの成分に加え、80℃まで加熱し、攪拌下、これにハの成分を徐々に加えて乳化し、攪拌冷却して、本発明の化粧料である、紫外線防護化粧料1を得た。同様に操作して、紫外線防護化粧料1のクエン酸を水に置換した比較例1及び「微粒子酸化亜鉛MZ−503S」を3質量%ステアリン酸アルミニウム被覆二酸化チタンに置換した比較例2も同様に製造した。   According to the formulation shown below, an ultraviolet protective cosmetic which is a cosmetic of the present invention was produced. That is, the components of (b) and (c) are preheated to 80 ° C., the components of (a) are separately mixed, the paste prepared by dispersing and homogenizing with a coball mill is added to the components of (b), heated to 80 ° C. The component C was gradually added and emulsified, followed by stirring and cooling to obtain an ultraviolet protective cosmetic 1 which is a cosmetic of the present invention. In the same manner, Comparative Example 1 in which the citric acid of the UV protective cosmetic 1 was replaced with water and Comparative Example 2 in which “fine-particle zinc oxide MZ-503S” was replaced with 3 mass% aluminum stearate-coated titanium dioxide were similarly used. Manufactured.

<試験例1>
上記の紫外線防護化粧料1、比較例1及び比較例2をガラス瓶及びポリエチレン瓶に高さが6cmになるように充填し、3年間室温で保存し、離水量を高さとして測定した。結果を表2に示す。これより、ガラス瓶では何れのサンプルも安定に保存され、ポリエチレンの瓶では、本発明の紫外線防護化粧料1と比較例2は安定に保存されたが、比較例1は明瞭に離水現象を引き起こしていた。かかる離水現象は、保存容器と、酸化亜鉛の相互作用によることがわかる。又、この相互作用はクエン酸の添加により、防止できることもわかる。尚、数値は離水層の厚さ(mm)を示す。
<Test Example 1>
The above UV protective cosmetic 1, Comparative Example 1 and Comparative Example 2 were filled in a glass bottle and a polyethylene bottle to a height of 6 cm, stored at room temperature for 3 years, and the water separation was measured as the height. The results are shown in Table 2. Thus, in the glass bottle, all samples were stably stored, and in the polyethylene bottle, the UV protective cosmetic 1 of the present invention and the comparative example 2 were stably stored, but the comparative example 1 clearly caused the water separation phenomenon. It was. It can be seen that this water separation phenomenon is caused by the interaction between the storage container and zinc oxide. It can also be seen that this interaction can be prevented by the addition of citric acid. In addition, a numerical value shows the thickness (mm) of a water separation layer.

実施例1の紫外線防護化粧料1と同様に、下記の処方に従って、本発明の化粧料である紫外線防護化粧料2を製造した。このものは、ポリエチレン容器保存3年の条件で離水層2mmを観察した。従って、クエン酸の含有量の下限値は0.1質量%であり、0.2質量%であることが好ましいことがわかる。   In the same manner as the ultraviolet protective cosmetic 1 of Example 1, an ultraviolet protective cosmetic 2 as a cosmetic of the present invention was produced according to the following formulation. This thing observed 2 mm of water separation layers on the conditions of a polyethylene container preservation | save for 3 years. Therefore, it can be seen that the lower limit of the citric acid content is 0.1% by mass, preferably 0.2% by mass.

実施例1の紫外線防護化粧料1と同様に、下記の処方に従って、本発明の化粧料である紫外線防護化粧料2を製造した。このものは、ポリエチレン容器保存3年の条件で離水を観察しなかった。これより、クエン酸添加効果が頭打ちであることがわかる。従って、化粧料としてはクエン酸の上限値は1質量%で、より好ましくは0.5質量%であることもわかる。   Similarly to the ultraviolet protective cosmetic 1 of Example 1, an ultraviolet protective cosmetic 2 that is a cosmetic of the present invention was produced according to the following formulation. This thing did not observe water separation on the conditions of a polyethylene container preservation | save for 3 years. From this, it can be seen that the citric acid addition effect has reached its peak. Therefore, it can also be seen that the upper limit of citric acid for cosmetics is 1% by mass, more preferably 0.5% by mass.

下記に示す処方に従って、紫外線防護化粧料1と同様に、本発明の化粧料である、紫外線防護化粧料4を製造した。このものを試験例1と同様に、クエン酸を水に置換した比較例3とともに、ガラス瓶、ポリエチレン容器保存を行ったところ、表6に示す結果となった。クエン酸の添加効果は認められるものの、その効果はステアリン酸ナトリウムの添加により損なわれていることがわかる。   According to the formulation shown below, the UV protective cosmetic 4 which is the cosmetic of the present invention was produced in the same manner as the UV protective cosmetic 1. When this was stored in a glass bottle and a polyethylene container together with Comparative Example 3 in which citric acid was replaced with water in the same manner as in Test Example 1, the results shown in Table 6 were obtained. Although the addition effect of citric acid is recognized, it turns out that the effect is impaired by the addition of sodium stearate.

<参考例>
以下に示す、処方に従って、酸化亜鉛を含有する油中水乳化剤形の紫外線防護化粧料(参考例)を作成した。即ち、イ、ロ、ハ、ニの成分を80℃に加熱し、イとロとを混合し、混練りし、これにハを加えて希釈し、これにホを加え、ディスパー分散させ、攪拌下徐々にニの成分を加え乳化し、攪拌冷却し、油中水乳化剤形の紫外線防護化粧料を得た。このものをポリエチレン樹脂瓶に充填し室温で3年間保存したが、安定に保存できた。離水現象は水中油乳化剤形に特異的に現れる現象であることが推測された。
<Reference example>
According to the formulation shown below, a water-in-oil emulsifier type UV protective cosmetic containing zinc oxide (reference example) was prepared. That is, a, b, c, and d are heated to 80 ° C., b and b are mixed, kneaded, c is added to dilute, d is added to this, disperse dispersed, and stirred. The two ingredients were gradually added and emulsified, and the mixture was stirred and cooled to obtain an ultraviolet protective cosmetic in the form of a water-in-oil emulsifier. This product was filled in a polyethylene resin bottle and stored at room temperature for 3 years, but could be stored stably. It was speculated that the water separation phenomenon appears specifically in the oil-in-water emulsifier form.
