例えば、特許文献1には、ジメチルジステアリルアンモニウムヘクトライト等の有機変性粘土鉱物と、デキストリン脂肪酸エステル、ショ糖脂肪酸エステル、及び脂肪酸又はその塩のような油相増粘剤を、シリコーン油を除く不揮発性液状油分に対して所定の質量比となるように配合することにより、水分と接触することによって塗布直後よりも紫外線防御効果が向上することが記載されている。
(A)6~40質量%の紫外線吸収剤、
(B)油相増粘剤、及び
(C)以下の(i)~(iii)から選択される1以上の疎水性粉末:
(i)疎水化処理タルク、
(ii)平均粒子径が30μm以上であるシリコーン粉末、
(iii)架橋密度が40%以上である架橋型ポリメチルメタクリレート粉末
を含み、
紫外線散乱剤を含まないか含んでも6質量%以下である、油中水型乳化化粧料を提供するものである。
すなわち、本発明は、紫外線防御能向上効果に加えて、塗布後の外観、使用性及び洗浄性にも優れた化粧料を提供できる。
本発明に係る油中水型乳化化粧料に配合される(A)紫外線吸収剤(以下、単に「(A)成分」と称する場合がある)は、日焼け止め化粧料に通常配合されるものを使用することができる。
本発明で用いられる紫外線吸収剤は、特に限定されるものではないが、具体例としては、メトキシケイヒ酸エチルヘキシル、オクトクリレン、ジメチコジエチルベンザルマロネート、ポリシリコン-15、t-ブチルメトキシジベンゾイルメタン、エチルヘキシルトリアゾン、ジエチルアミノヒドロキシベンゾイル安息香酸ヘキシル、ビスエチルヘキシルオキシフェノールメトキシフェニルトリアジン、オキシベンゾン-3、メチレンビスベンゾトリアゾリルテトラメチルブチルフェノール、フェニルベンズイミダゾールスルホン酸、ホモサレート、サリチル酸エチルへキシル等の有機紫外線吸収剤を挙げることができる。
本発明に係る油中水型乳化化粧料に配合される(B)油相増粘剤(以下、単に「(B)成分」と称する場合がある)は、油中水型乳化化粧料の油相の粘度を調整することができるものである。(B)成分としては、デキストリン脂肪酸エステル、ショ糖脂肪酸エステル、脂肪酸もしくはその塩、植物性硬化油又は固形もしくは半固形の植物油、有機変性粘土鉱物、グリセリル脂肪酸エステル、及び、アミノ酸系ゲル化剤が好ましい。
また、植物性硬化油と同様に、室温で固形又は半固形の植物油も使用することができる。ここで、固形油とは25℃において固体の油を意味し、半固形油とは25℃において半量が固体である油を意味する。より具体的には、融点が44℃~90℃の範囲であり、25℃でB型粘度計により測定した粘度が5000mPa・s以上のもの、さらには10000mPa・s以上であるものが好ましい。室温で固形又は半固形の植物油としては、カカオ脂、ヤシ油、パーム油、パーム核油、モクロウ、シアバター等を例示することができる。

(但し、X=Al,Fe(III),Mn(III),Cr(III)、Y=Mg,Fe(II),Ni,Zn,Li、Z=K,Na,Ca)
本発明に係る油中水型乳化化粧料に配合される疎水性粉末(以下、単に「(C)成分」と称する場合がある)は、水との相互作用が小さく、水との親和性が小さい粉末粒子であり、通常化粧料において使用性を改善する目的で配合される場合が多い。疎水性粉末は、本来的に疎水性の素材の粉末粒子の他、親水性または疎水性の粉末粒子を基素材としこれに疎水化処理を施した粉末が含まれる。
これらの中でも本発明に係る油中水型乳化化粧料に配合される(C)疎水性粉末は、以下の(i)~(iii)のタイプ:
(i)疎水化処理タルク、
(ii)平均粒子径が30μm以上であるシリコーン粉末、
(iii)架橋密度が40%以上である架橋型ポリメチルメタクリレート粉末
から選択されるのが好ましい。
疎水化処理タルクは、ケイ酸塩系粘土鉱物であるタルクを基素材とし、その表面を疎水化処理した粉末である。後述する実施例に示すように、疎水化処理タルクは、疎水化処理の種類を問わず紫外線防御能向上効果を発揮できるため、(C)成分の中でも特に好ましい。
疎水化処理は、特に制限されるものではないが、例えば、シリコーン処理(メチルハイドロジェンポリシロキサン、ジ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オイル;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等のアルキルシラン;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等による処理)、脂肪酸処理(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による処理)、脂肪酸石鹸処理(ステアリン酸アルミニウム、ステアリン酸カルシウム、12-ヒドロキシステアリン酸等による処理)、脂肪酸エステル処理(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等による処理)等が挙げられる。これらの疎水化処理は、常法に従って行うことができる。疎水化処理の中でも、粉末粒子に高い安定性を付与可能である等の点から、シリコーン処理が好適である。
疎水化処理タルクは市販品を利用することができ、例えば「ステアリン酸カルシウム処理タルク」(藤本化学製品株式会社製)を挙げることができる。
シリコーン粉末は、平均粒子径が30μm以上であれば、化粧料原料として通常用いられているものを使用することができる。シリコーン粉末としては、例えば、メチルポリシロキサン網状重合体、架橋型メチルポリシロキサン、架橋型シリコーン網状型シリコーンブロック共重合体及びシリル化シリカ等が知られているが、これらの中でも、特に架橋型シリコーン網状型シリコーンブロック共重合体が好ましい。
架橋型ポリメチルメタクリレート粉末(PMMA粉末)は、架橋密度が40%以上であるものを使用することができる。架橋型ポリメチルメタクリレート粉末の架橋密度は、40%以上であり、より好ましくは42%以上、さらに好ましくは45%以上である。架橋密度が40%未満のPMMA粉末を使用した場合には、水分との接触により紫外線防御効果が損なわれる傾向がある。一方、架橋密度の上限は特に制限されないが、使用性の観点から60%以下が好ましい。架橋密度は、溶媒膨潤法等の公知の種々の方法によって求めることができる。
本発明の油中水型乳化化粧料は、紫外線散乱剤を配合しなくても、上記(A)~(C)成分を含有することによって紫外線防御能向上効果を実現することができる。
しかし、紫外線に対する防御効果をさらに向上させる等の目的で、紫外線散乱剤を少量配合することは差し支えない。本発明の油中水型乳化化粧料に紫外線散乱剤を配合する場合には、紫外線散乱剤による白浮きや使用性の低下を抑えるために、油中水型乳化化粧料全量に対して、6%質量以下、好ましくは5質量%以下、さらに好ましくは4質量%以下、特に好ましくは3質量%以下とするのが好ましい。
HLBが8未満のシリコーン系界面活性剤としては、例えば、ポリオキシアルキレン変性シリコーン、ポリオキシアルキレン・アルキル共変性シリコーン、ポリグリセリン変性シリコーン、及び/又はポリグリセリン・アルキル共変性シリコーンを挙げることができる。具体例には、KF-6017(PEG-10ジメチコン、信越化学工業株式会社製)、KF-6028(PEG-9ポリジメチルシロキシエチルジメチコン、信越化学工業株式会社製)、ABIL EM90(セチルPEG/PPG-10/1ジメチコン、Evonik Goldschmidt社製)、KF-6038(ラウリルPEG-9ポリジメチルシロキシエチルジメチコン、信越化学工業株式会社製)、ビスブチルジメチコンポリグリセリル-3等が含まれる。
シリコーン系界面活性剤の配合量は、油中水型乳化化粧料全量に対して、好ましくは0.1~8質量%、さらに好ましくは0.2~7質量%、より好ましくは0.4~5質量%である。
以下の表1及び表2に掲げた組成を有する油中水型乳化化粧料を、油性成分を加温して溶解し粉末を分散させたものに、別途混合した水相を添加し、攪拌処理にて乳化することにより調製した。
測定プレート(Sプレート)(5×5cmのV溝PMMA板、SPFMASTER-PA01)に各例の化粧料(サンプル)を2mg/cm2の量で滴下し、60秒間指で塗布し、15分間乾燥した後に形成された塗膜の吸光度を株式会社日立製作所社製U-3500型自記録分光光度計にて測定した。無塗布をコントロールとし、吸光度(Abs)を以下の式で算出し、280nm~400nmにおける測定値を積算した。
Abs=-log(T/To)
T:サンプルの透過率、To:無塗布の透過率
測定したプレートを硬度50~500の水に十分に浸し、30分間そのまま水中で撹拌した(スリーワンモーターで300rpm)。その後、表面の水滴がなくなるまで15~30分程度乾燥させ、再び吸光度を測定し、水浴前後のAbs積算値からAbs変化率(以下の式)を紫外線防御能向上効果として算出した。
紫外線防御能向上効果:
Abs変化率(%)=(水浴後のAbs積算値)/(水浴前のAbs積算値)×100
一方、平均粒子径が30μm未満のシリコーン粉末や無水ケイ酸(シリカ粉末)を使用した場合には、Abs変化率が100%を下回り、紫外線防御能向上効果は見られなかった(比較例1~3)。
下記の表3に掲げた組成を有する油中水型乳化化粧料を調製し、上記と同様に水浴前後のAbs変化率を求めた。
一方、本発明で使用可能な特定の疎水性粉末を含まない場合には、他の一般的な粉末成分を同等量配合しても紫外線防御能向上効果は得られなかった(比較例4~7)。
下記の表4に掲げた組成を有する油中水型乳化化粧料を調製し、上記と同様に水浴前後のAbs変化率を求めた。
一方、本発明で使用可能な特定の疎水性粉末を含まない場合には、水浴攪拌後に 紫外線防御能向上効果は得られなかった(比較例8)。
下記の表5A及び表5Bに掲げた組成を有する油中水型乳化化粧料を調製し、上記と同様に水浴前後のAbs変化率を求めた。
これにより、少なくとも1種の油相増粘剤と疎水性粉末とを組み合わせて配合することにより、十分な紫外線防御能向上効果を達成できることが確認された。
