Abstract
Description
しかし、紫外線散乱剤のような粉体を高配合すると、化粧料として皮膚に塗布した際には、きしきしといった感触を与えてしまう。このような肌への負担感を軽減することが非常に困難であった。
すなわち、本発明にかかる化粧料は、
粉末を分散させた粉末分散組成物を配合した化粧料であって、前記分散組成物中の粉末の平均粒径が粉末の一次粒子径の10倍以下であり、前記分散組成物中の平均粒径の多分散指数(PDI値)が、0.14以下であり、前記粉末の1%あたりの吸光度 が150以上であることを特徴とする。
また、本発明において、化粧料は、分散剤 のHLBが、2以下のシリコーン油であることが好適である。
また、本発明において、化粧料は、分散剤が、両末端シリコーン変性グリセリンであることが好適である。
また、本発明において、化粧料は、粉末が、二酸化チタン、酸化亜鉛であることが好適である。
また、本発明において、化粧料は、粉末の配合量が30%以下であることが好適である。
本発明において好適に用いられる粉末分散組成物としては、粉末と、それを分散する分散剤および分散媒からなる。
本発明に用いる粉末としては、紫外線散乱剤を好適に配合することができる。紫外線散乱剤としては、例えば、酸化チタン、酸化亜鉛、酸化セリウム等の無機粉末、或いはこの無機粉末の表面をメチルハイドロジェンポリシロキサン、メチルポリシロキサン、メチルフェニルポリシロキサン等のシリコーン処理;パーフルオロアルキルリン酸エステル、パーフルオロアルコール等によるフッ素処理;N-アシルグルタミン酸等によるアミノ酸処理;レシチン処理;ステアリン酸アルミニウム、ステアリン酸カルシウム、ステアリン酸マグネシウム等の金属石鹸処理;パルミチン酸、イソステアリン酸、ステアリン酸、ラウリン酸、ミリスチン酸、ベヘニン酸、オレイン酸、ロジン酸、12-ヒドロキシステアリン酸等の脂肪酸処理;アルキルリン酸エステル処理、メチルトリメトキシシラン、エチルトリメトキシシラン、ヘキシルトリメトキシシラン、オクチルトリメトキシシラン、オクチルトリエトキシシランなどのアルコキシシラン処理、トリフルオロメチルエチルトリメトキシシラン、ヘプタデカフルオロデシルトリメトキシシラン等のフルオロアルキルシラン処理、デキストリン脂肪酸エステル、コレステロール脂肪酸エステル、ショ糖脂肪酸エステル、デンプン脂肪酸エステルなどの脂肪酸エステル処理、シリカ処理等により被覆した表面被覆無機粉末が挙げられる。
本発明に用いる粉末が分散する分散媒としてはシリコーン油、炭化水素油、エステル油などの油分が挙げられる。
分散媒の配合量は、粉末分散組成物中25~80質量% 、さらには30~70質量%であることが好適である。80質量%を超えると、十分な量の紫外線散乱剤が配合できない場合があるため好ましくない。25質量%未満であると、分散媒が少なすぎて分散ができない場合があるため好ましくない。
本発明で用いるシリコーン系分散剤は、下記一般式(a)で表される両末端シリコーン変性グリセリンであることを特徴とする。
R 2 は炭素数2 ~ 1 1 のアルキレン基であり、m は1 0 ~ 1 2 0 、n は1 ~ 1 1 である。
Aはグリセリン残基である。
下記構造(c)の片末端水素シリコーンは公知の化合物である。そして、任意の重合度のBAB型トリブロック共重合体が公知の方法により製造出来る。
グリセリン鎖の重合度のnは1~11が好ましい。
第1工程では、分散媒と、粉末とを撹拌しながら混合する。そして、第2工程では、第1工程で得られた混合物をキャビテーションの原理に基づいて均質化させることを特徴とする。
キャビテーションは、液体の流れの中で圧力差により短時間に泡の発生と消滅が起きる物理現象である。
本発明において、粉末分散組成物を得るために、第1工程で得られた混合物に流速を付与した液体を、絞り流路を通過させることによって、液体にキャビテーションによる微細気泡を発生させて、その衝撃力で、粉末分散組成物を得る。
付与する流速は、50~200MPaの超高圧流で与える。50未満であると、分散効果がない場合があるため好ましくない。
PDIが0.1以下の場合は単分散性の粒子で、また、0.1を超えて0.4の間の値を有する分散体は、狭い粒子サイズ分布を有すると考えられる。PDIが0.4を超えて0.5以下の場合は、比較的広い粒子サイズ分布と考えられ、さらに、PDIが0.5より大きくなると、その分散体は多分散性であると考えられる
上記式中、d:粒子径(nm)、k:ボルツマン定数(1.38×10-23 J・K-1)、T:絶対温度(K)、η:粘度(mPa・s)、D:拡散係数(m2・s-1)を表す。
また、O/W化粧料に、粉末分散組成物を用いる場合は、O/W化粧料中に、粉末が、8~30質量%であると、高いSPFを維持したまま、肌への負担感を軽減できるため好ましい。
本発明にかかるO/W化粧料は、O/W化粧料の製造に従来から使用されている方法に準じて製造することができる。
また、W/O化粧料に、粉末分散組成物を用いる場合は、W/O化粧料中に、粉末が、10~30質量%であると、高いSPFを維持したまま、肌への負担感を軽減できるため好ましい。
本発明にかかるW/O化粧料は、W/O化粧料化粧料の製造に従来から使用されている方法に準じて製造することができる。
本発明の化粧料には、上記O/W化粧料またはW/O化粧料処方以外の乳化をしていない化粧料も含まれる。また本発明の化粧料には必須成分の外、通常化粧品や医薬部外品の組成物に用いられる成分を配合することができ、常法に応じて製造される。以下に具体的な配合可能成分を列挙するが、前記必須成分に加え、下記成分の一種又は二種以上とを配合して本発明の組成物を調製できる。配合できる成分は下記に限定されず、下記成分以外の任意の成分も配合可能である。
ただし、高屈折率(屈折率2以上など)の無機粉体を配合する場合には、組成物中5質量%以下、好ましくは1質量%以下とすることが好ましい。
シリコーン油としてはポリジメチルシロキサン、メチルフェニルポリシロキサン、メチルハイドロジェンポリシロキサンなどの鎖状シリコーン油、およびオクタメチルシクロテトラシロキサン、デカメチルシクロペンタシロキサン、ドデカメチルシクロヘキサシロキサンなどの環状シリコーン油等が挙げられる。

まず、試験方法について説明する。
(分散状態)
作製したサンプルの分散状態を顕微鏡により確認をおこなった。100倍で見たときの視野中に凝集物が1つもない状態をA、10個以下をB、50個以下をC、それ以上をDとし、AとBを分散状態が良いと判断した。
Sun Protection Factor(SPF)は、SPF測定装置「SPF MASTER」(登録商標)(資生堂)を用いて測定した。
多分散指数は、動的光散乱法(DLS)により粒子サイズ測定により測定した。
粉末分散組成物中の粉末の粒径は、動的光散乱法により測定した。
粉末分散組成物に用いた粉末の平均一次粒径は、窒素吸着法で測定した。
粉末分散組成物の吸光度は、粉末分散組成物を分散媒で希釈して、10mm四方の液体セルに入れて測定した。
化粧料の粘度は、B型粘度計により測定した。
化粧料の負担感は、10名の官能検査パネルにより、各試料を適量手に取り、頬部に塗布し、判定を行った。
<評価基準>
A:パネル10人中8名以上が負担感がないと回答した。
B:パネル10人中4~7名が負担感がないと回答した。
C:パネル10人中0~3名が負担感がないと回答した。
**動的散乱法
1)含水シリカ/ジメチコン処理微粒子酸化亜鉛
2)ステアリン酸/酸化アルミニウム処理微粒子酸化チタン
また、ホモミキサーに比べて、キャビテーションにより得た粉末分散組成物の多分散指数が、0.4以下であるため、理想的な単一サイズであると考えられ、狭い粒子サイズ分布を有すると分かった。
さらに、キャビテーションにより得た粉末分散組成物に用いる粉末は、酸化チタン以外のその他の粉末でも微粒子化できることができ、経時で粘度が安定することが分かった。
