Description
本願は、2009年9月15日に、日本に出願された特願2009-213235号に基づき優先権を主張し、その内容をここに援用する。
中でも、近紫外線を含む巾広い波長領域の紫外線を遮蔽する無機系紫外線遮蔽材料である金属酸化物としては、酸化亜鉛、酸化チタン等が挙げられ、これらは白色顔料としても重要である。これらの金属酸化物は、基材中に分散させたときの分散粒子径を0.1μm以下とすることにより、可視光線をほとんど吸収せずに透過させ、紫外線をほぼ吸収することができる。
酸化亜鉛は、古くから油分を吸収する性質があることが知られており、また、水中に溶解した際に生じる亜鉛イオンは、脂肪酸と反応して金属石鹸を生成することから、皮膚から分泌される皮脂吸収剤、体臭成分を吸収するデオドラント剤として利用されている。さらに、亜鉛イオンは生理作用があることから、古くから収斂剤としても利用されている。
このような問題点を解消するためには、酸化亜鉛や酸化チタンの分散粒子径を0.1μm以下にする必要があるが、酸化亜鉛や酸化チタンの分散粒子径を0.1μm以下にするためには、高度な分散技術が必要となり、現状では非常に難しい。さらに、このような酸化亜鉛や酸化チタンの微粒子は、皮膚の汗腺等から体内に吸収される虞があり、人体に対する安全性等の点で懸念が生じる虞がある。
また、酸化亜鉛は、水に微量溶解する性質があり、その溶出した亜鉛イオンによる作用で体臭成分を吸収するデオドラント剤または収斂剤として利用されることもあるが、同時に溶出した亜鉛イオンが化粧品の他の成分である油剤、香料、色料、有機紫外線吸収剤、水溶性高分子等と反応して、粘度の変化、異臭の発生、変色、着色、ゲル化等を誘起する虞があるために、化粧料中の水の含有率を高めることができず、化粧料としての処方の自由度が低下するという問題点もある。
また、樹脂粉体の平均粒子径を0.1μm以上かつ1μm以下としたので、化粧品に用いた場合においても、ざらつき感等がなく、使用感に優れている。
なお、この形態は、発明の趣旨をより良く理解させるために具体的に説明するものであり、特に指定のない限り、本発明を限定するものではない。
本実施形態の金属酸化物内包樹脂粉体は、(メタ)アクリル系樹脂に、平均粒子径が0.003μm以上かつ0.1μm以下の紫外線遮蔽能を有する金属酸化物粒子を内包してなる樹脂粉体であり、この樹脂粉体の平均粒子径は0.1μm以上かつ1μm以下、この金属酸化物粒子は、樹脂粉体の表面にて露出することなく樹脂粉体中に分散した粉体である。
ここで、金属酸化物粒子が樹脂粉体の表面にて露出することなく樹脂粉体中に分散した状態とは、樹脂粉体中に分散した金属酸化物粒子が、この樹脂粉体中に完全に埋め込まれており、しかも、この樹脂粉体の表面は樹脂により完全に覆われた状態で、この覆われた樹脂の表面には金属酸化物粒子が全く露出していない状態のことである。
一般的に、粉体の粒子径が小さいほど、即ち樹脂粉体の比表面積が大きいほど、亜鉛の溶出量は増加する傾向にある。したがって、本実施形態の金属酸化物内包樹脂粉体は、比表面積が大きいにもかかわらず亜鉛(Zn)の溶出量を少なく抑えられることから、酸化亜鉛粒子の周囲が樹脂で充分に被覆され、しかも、この金属酸化物内包樹脂粉体の表面に酸化亜鉛微粒子が露出していないということができる。
これらのモノマーは、1種のみを単独で重合してもよく、2種以上を組み合わせて重合してもよい。
金属酸化物粒子の平均粒子径が0.003μm未満では、結晶化度が低下して紫外線遮蔽機能を発現しなくなり、また、平均粒子径が0.1μmを超えると、粒子の可視光線に対する散乱係数が大きくなるために、透明性が著しく低下し、その結果、可視光線に対する光透過性が低下し、透明性が悪くなるので、好ましくない。
この金属酸化物粒子は、オルガノポリシロキサンにより表面処理したものを用いてもよい。
ここで、金属酸化物粒子の樹脂粉体における含有率が1質量%未満では、金属酸化物粒子の量が少なすぎて、金属酸化物粒子が有する紫外線遮蔽機能を十分に発現することができなくなり、したがって、紫外線遮蔽機能を十分に発現させようとすると、大量の樹脂粉体が必要となり、化粧品を作製する際の材料設計が極めて難しくなり、一方、含有率が80質量%を超えると、金属酸化物粒子の量が樹脂に対して相対的に高くなり、その結果、樹脂中における金属酸化物粒子の分散性が低下し、組成の均一性が損なわれるので、好ましくない。
ここで、金属酸化物粒子の樹脂粉体中の分散粒子径が0.1μmを超えると、樹脂粉体の可視光線に対する散乱係数が大きく、透明性が著しく低下することとなり、その結果、透明性が低下し、場合によっては失透する虞があるので、好ましくない。
ここで、樹脂粉体の平均粒子径が0.1μm未満では、脱水処理が難しくなって凝集し易くなり、その結果、樹脂粉体同士の凝集性が強くなって分散性が低下し、紫外線遮蔽機能を十分に発現することができなくなり、一方、平均粒子径が1μmを超えると、化粧料として用いた場合に、肌における伸びや滑りが低下し、その結果、ざらつき感等が生じて肌触り等が悪化する等、使用感が悪くなるので好ましくない。
ここで、純水及び酢酸水溶液への金属元素の溶出量を上記の範囲に限定した理由は、この範囲が、この樹脂粉体を化粧料として用いた場合に、この樹脂粉体の成分である金属酸化物が純水等の溶媒中への溶出を抑制することができる範囲だからである。金属元素の溶出量を上記の範囲に限定することで、溶出した金属イオンが化粧料の他の成分と反応して、成分が変化したり、変色したり等の不具合を防止することができる。
このオルガノシロキサンとしては、ジアルキルアルコキシシラン化合物が挙げられ、中でも、オルガノポリシロキサン、あるいは、オルガノポリシロキサンをアルキル基、イソシアネート基、エポキシ基、アクリル基、アルキル珪素化合物の群から選択された1種または2種以上により変性した変性オルガノポリシロキサンが好適に用いられ、特に、ジメチルポリシロキサン(シリコーンオイル)、このジメチルポリシロキサン(シリコーンオイル)を変性した変性ジメチルポリシロキサン(変性シリコーンオイル)が好適に用いられる。
この樹脂粉体の表面をオルガノシロキサンにより処理することにより、この樹脂粉体の成分である金属酸化物の純水等の溶媒中への溶出を、さらに抑制することができる。
本実施形態の金属酸化物粒子内包樹脂粉体分散液は、上記の金属酸化物粒子内包樹脂粉体を分散媒中に分散してなる分散液である。
また、分散処理に要する時間は、金属酸化物粒子内包樹脂粉体が分散媒中に分散するのに十分な時間であればよく、特に制限はされない。
分散液の光透過率を上記の範囲とすることにより、可視光線に対する透明性を確保することができる。
本実施形態の金属酸化物粒子内包樹脂粉体の製造方法は、平均粒子径が0.003μm以上かつ0.1μm以下の紫外線遮蔽能を有する金属酸化物粒子を、この金属酸化物粒子に対して1質量%以上かつ50質量%以下の分散剤を含む(メタ)アクリル系樹脂モノマー中に分散させて(メタ)アクリル系樹脂モノマー分散液とし、次いで、この(メタ)アクリル系樹脂モノマー分散液を、この(メタ)アクリル系樹脂モノマー分散液に対して、0.1質量%以上かつ10質量%以下の懸濁保護剤、0.01質量%以上かつ5質量%以下のシリコーン系消泡剤及び0.1質量%以上かつ10質量%以下の架橋剤を含む純水中に懸濁または乳化させて分散粒子径が0.1μm~1μmの懸濁液または乳化液とし、次いで、この懸濁液または乳化液に、この懸濁液または乳化液に対して0.01質量%以上かつ1質量%以下の重合開始剤を添加して懸濁重合または乳化重合を行うことにより、金属酸化物粒子内包樹脂粉体を生成する方法である。
まず、平均粒子径が0.003μm以上かつ0.1μm以下の紫外線遮蔽能を有する金属酸化物粒子を、分散剤を含む(メタ)アクリル系樹脂モノマー中に分散させ、(メタ)アクリル系樹脂モノマー分散液とする。
分散剤としては、樹脂モノマーとの親和性に富み、疎水性の高いものがよい。すなわち、分散剤は金属酸化物を被覆することで樹脂モノマーに対する分散を促し、同時に金属酸化物の粒子は比較的に短時間のうちに、ほとんどが単分散状態となり、平均分散粒子径は0.003μm以上かつ0.1μm以下となる。
また、分散剤は金属酸化物粒子に疎水性を与えるので、金属酸化物粒子が重合体の外に出ず、水相に移行することなく樹脂中に取り込まれるのを助ける。
分散剤の金属酸化物粒子に対する添加率は、1質量%以上かつ50質量%以下が好ましい。添加率が1質量%未満では、金属酸化物粒子の表面を覆うには少なすぎて十分な金属酸化物粒子の分散状態を得ることができず、一方、50質量%を超えると、これ以上添加率を上げても、さらに分散性を改善することができず、分散剤が無駄になるからである。
分散時間としては、30分~3時間程度が好ましいが、分散状態と製造コストとの兼ね合いで適切な時間を選べばよい。
以上により、金属酸化物粒子の平均分散粒子径が0.003μm以上かつ0.1μm以下の(メタ)アクリル系樹脂モノマー分散液を得ることができる。
懸濁保護剤としては、ポリオキシエチレンアルキルエーテル、ポリオキシエチレンアルキルフェニルエーテル等の非イオン性界面活性剤、あるいはアルキルベンゼンスルホン酸塩、アルキル硫酸エステル塩、アルキルフェニル硫酸エステル塩等の陰イオン性界面活性剤等が挙げられ、これらの中でも、陰イオン性界面活性剤が好ましく、この陰イオン性界面活性剤としては、アルキルベンゼンスルホン酸塩が好ましい。
懸濁保護剤の添加量は、上記の(メタ)アクリル系樹脂モノマー分散液に対して0.1質量%以上かつ10質量%以下、より好ましくは、0.1質量%以上かつ2質量%以下である。
シリコーン系消泡剤は、上記(メタ)アクリル系樹脂モノマー分散液に対して0.01質量%以上かつ5質量%以下添加することにより、分散機や混合機の攪拌速度を大幅に上げることができ、その結果、樹脂粉体を100nm程度まで小さくすることができ、化粧料等に配合した時に、より透明性にすぐれた、ざらつき感等がない使用感に優れた化粧料を提供することが可能である。また、分散機や混合機の攪拌速度を大幅に上げることができ、その結果金属酸化物粒子内包樹脂粉体の製造効率を向上させることができるので、製造コストを大幅に削減することができる。
より具体的には、ジビニルベンゼン、ジビニルビフェニル、ジビニルナフタレン、(ポリ)エチレングリコールジ(メタ)アクリレート、(ポリ)プロピレングリコールジ(メタ)アクリレート、(ポリ)テトラメチレングリコールジ(メタ)アクリレート等の(ポリ)アルキレングリコール系ジ(メタ)アクリレートが挙げられる。
これらの中でも特に(ポリ) エチレングリコールジ( メタ) アクリレートが好ましい。
また、(メタ)アクリル系樹脂モノマー分散液に対してシリコーン系消泡剤を0.01質量%以上かつ5質量%以下添加することにより、分散機や混合機の撹拌速度を大幅に上げることができ、その結果、金属酸化物粒子内包樹脂粉体の製造効率を向上させることができ、その結果、製造コストを大幅に削減することができる。
重合方法としては、上記の懸濁液または乳化液を窒素雰囲気下、かつ重合開始剤の存在下にて、攪拌しながら昇温して重合を開始させる方法が好ましい。
この重合開始温度は50~80℃とするのが好ましい。そして、この温度を保持しながら重合させる時間としては、1~5時間程度が好ましく、未反応の残留モノマーが最小となる時間および重合状態、製造コストとの兼ね合いで適当な時間を選べばよい。
その後、氷冷または自然冷却し、重合反応を停止させる。
アルコールは、純水に可溶なもので容易に洗い流せるものであればよく、例えば、エタノール、2-プロパノール等がなどがあげられ、特に2-プロパノールが好ましい。
洗浄方法は、残留モノマー等を除去できれば特に限定されないが、加圧ろ過や、吸引ろ過、フィルタープレス、遠心分離、限外ろ過、デカンテーション等により洗浄する。洗浄は2-プロパノール濃度計で1%以下、導電率計で20μS/cm以下になるまで行う。
粉砕方法は、0.1μm以上かつ1μm以下の大きさに粉砕することができる方法であれば特に限定されないが、ピンミル、ハンマーミル、ジェットミル、インペラーミル等が挙げられる。
以上により、金属酸化物粒子内包樹脂粉体を生成することができる。
この金属酸化物粒子内包樹脂粉体は、粉砕工程を経ることにより、乾燥により凝集した各粒子を粉砕し、化粧料に使用した場合の使用感を向上させることができる。
本実施形態の金属酸化物粒子内包樹脂粉体水系分散体は、上記の金属酸化物粒子内包樹脂粉体を1質量%以上かつ80質量%以下、より好ましくは20質量%以上かつ70質量%以下、さらに好ましくは30質量%以上かつ60質量%以下含有するとともに、アルコールを5質量%以上かつ20質量%以下含有してなる水系分散体である。
特に、アルコールの含有率を10質量%以上かつ20質量%以下とした場合、金属酸化物粒子内包樹脂粉体の分散性及び経時安定性を向上させることができるので好ましい。
水溶性高分子は分散剤、粘度調整の役割を有し、添加することによって金属酸化物粒子内包樹脂粉体の分散性及び経時安定性も向上する。
ここで、水系分散体が水溶性高分子を含む場合のアルコールの含有率を5質量%以上かつ20質量%以下とした理由は、含有率が5質量%未満では、アルコールが少なすぎるために、水溶性高分子が均一にアルコール浸潤できずに水分にて不均一に膨潤することとなり、その結果、金属酸化物粒子内包樹脂粉体の分散性が低下して取扱いが困難となり、さらには経時安定性が低下するので、好ましくない。また、含有率が20質量%を超えると、水系分散体全体の粘性が高くなり、金属酸化物粒子内包樹脂粉体の分散安定性が低下するとともに、経時安定性も低下するので、好ましくない。
本実施形態の化粧料は、上述した金属酸化物内包樹脂粉体、金属酸化物粒子内包樹脂粉体分散液、金属酸化物粒子内包樹脂粉体水系分散体、の群から選択される1種または2種以上を、金属酸化物粒子内包樹脂粉体換算で1質量%以上かつ50質量%以下含有した化粧料であり、この金属酸化物粒子内包樹脂粉体を上記の範囲内で含むことにより、白化の虞もなく透明感を十分に確保することができ、しかも、ざらつき感等が無く、使用感に優れている。
この化粧料は、上述した金属酸化物内包樹脂粉体、金属酸化物粒子内包樹脂粉体分散液、金属酸化物粒子内包樹脂粉体水系分散体、の群から選択される1種または2種以上を、乳液、クリーム、ファンデーション、口紅、頬紅、アイシャドー等に従来通りに配合することにより得ることができる。
また、上述した金属酸化物内包樹脂粉体、金属酸化物粒子内包樹脂粉体分散液及び金属酸化物粒子内包樹脂粉体水系分散体のいずれか1種または2種以上に有機系紫外線吸収剤、例えば、アゾベンゼン等のアゾ染料を添加することにより、紫外線吸収能及び使用感に優れた化粧料を提供することができる。
