ここでIOBとは、Inorganic/Organic Balance(無機性/有機性比)の略であって、無機性値の有機性値に対する比率を表す値であり、有機化合物の極性の度合いを示す指標となるものである。IOB値は、具体的には、IOB値=無機性値/有機性値として表される。「無機性値」、「有機性値」のそれぞれについては、例えば、分子中の炭素原子1個について「有機性値」が20、水酸基1個について「無機性値」が100といったように、各種原子又は官能基に応じた「無機性値」、「有機性値」が設定されており、有機化合物中の全ての原子及び官能基の「無機性値」、「有機性値」を積算することによって、当該有機化合物のIOB値を算出することができる(例えば、甲田善生著、「有機概念図-基礎と応用-」p11~17、三共出版、1984年発行参照)。
(C)エステル油の配合量は、乳化化粧料全量に対して1.0質量%以上であり、例えば1.0~60質量%、好ましくは3.0~50質量%である。配合量が1.0質量%未満であると、熱による紫外線防御能向上の効果が十分に得られない場合があり、60質量%を超えて配合すると安定性や使用性に影響を及ぼす場合がある。

多価アルコールは、上記(B)成分と同様に通常の化粧料では保湿剤として配合されることが多い。本発明の乳化化粧料においては、前記(B)成分と多価アルコールとを組み合わせて配合した場合には、熱が加わった後の紫外線防御効果の向上が顕著となる。
HO(RO)pH (II)
(式中、ROは炭素原子数2~4のオキシアルキレン基を示し、pは3~500である)
で表されるものである。
具体的には、ポリエチレングリコール(「PEG」とも表記する)、ポリプロピレングリコール(「PPG」とも表記する)およびポリブチレングリコール(「PBG」とも表記する)等、化粧料に広く使用されているものから選択される。
低級アルコールとしては、エタノール、イソプロパノールなどの炭素数1~5のアルコールが挙げられる。低級アルコールを配合することにより、乳化化粧料を塗布する際の伸びを改善することができる。低級アルコールを配合する場合の配合量としては、例えば、乳化化粧料全量に対して5~30質量%とすることができる。
油相増粘剤としては、乳化型化粧料等において油分に溶解又は油分で膨潤することにより油相を増粘する効果を発揮する成分として使用されている物質が好ましい。例えば、パルミチン酸デキストリン、ミリスチン酸デキストリン等のデキストリン脂肪酸エステル、ショ糖カプリル酸エステル等のショ糖脂肪酸エステル、ワセリン、水添パーム油、水添ヒマシ油等の固形又は半固形の炭化水素油、ジステアルジモニウムヘクトライト、ベンジルジメチル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、あるいは、ラウリン酸、ミリスチン酸、パルミチン酸、ステアリン酸等の常温で固体の炭素数8~22の高級脂肪酸又はその塩等が挙げられる。
界面活性剤としては、油中水型乳化化粧料の場合は、シリコーン骨格(ポリシロキサン構造)を有し、HLBが8未満の界面活性剤が好ましい。例えば、ポリエーテル変性シリコーン、ポリエーテル・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、および/又はポリグリセリン・アルキル共変性シリコーンの使用が好ましく、なかでも、ポリエーテル変性シリコーン、ポリエーテル・アルキル共変性シリコーンがより好ましい。
また、本発明の乳化化粧料には、前記(C)エステル油以外に、化粧料に通常用いられる揮発性油分や非揮発性油分がさらに配合されてよい。
揮発性油分としては、揮発性炭化水素油及び揮発性シリコーン油が含まれる。
揮発性炭化水素油分としては、従来から化粧料等に使用されている常温(25℃)で揮発性を有する炭化水素油であれば特に限定されない。具体例としては、例えば、イソドデカン、イソヘキサデカン、水添ポリイソブテン等を挙げることができる。
揮発性シリコーン油としては、従来から化粧料等に使用されている常温(25℃)で揮発性を有するシリコーン油であって、ケイ素原子数4~6の環状ジメチルポリシロキサン、ケイ素原子数2~5の鎖状ジメチルポリシロキサンが含まれる。具体例としては、ヘキサメチルシクロトリシロキサン(D3)、オクタメチルテトラシクロシロキサン(D4)、デカメチルシクロペンタシロキサン(D5)、及びドデカメチルシクロヘキサシロキサン(D6)等の環状シリコーン油、ジフェニルシロキシフェニルトリメチコン、揮発性ジメチコン(市販品としては、KF-96L-1.5cs、KF-96L-2cs;信越化学工業社製)などを挙げることができる。
具体例としては、パーム油、アマニ油、ツバキ油、マカデミアナッツ油、トウモロコシ油、オリーブ油、アボカド油、サザンカ油、ヒマシ油、サフラワー油、キョウニン油、シナモン油、ホホバ油、ブドウ油、アルモンド油、ナタネ油、ゴマ油、ヒマワリ油、小麦胚芽油、米胚芽油、米ヌカ油、綿実油、大豆油、落花生油、茶実油、月見草油、卵黄油、肝油、トリグリセリン、トリオクタン酸グリセリル、トリイソパルミチン酸グリセリル、イソステアリン酸等の液状油脂;水添ポリイソブテン、流動パラフィン、スクワラン、水添ポリデセン等の炭化水素油;ポリオキシブチレンポリオキシプロピレングリコール、非揮発性ジメチコン(市販品としては、KF-96A-6cs;信越化学工業社製)等のシリコーン油が挙げられる。
また、球状粉末をさらに含むことが好ましい。球状粉末を配合することにより、べたつきが抑えられ、使用感が改善されてさらさらとした良好な感触を得ることができる。球状粉末としては、一般に化粧品等において用いられるものであれば特に制限されることなく任意に使用し得る。例えば、(メタ)アクリル酸エステル樹脂粉末、ポリアミド樹脂粉末(ナイロン粉末)、ポリエチレン粉末、ポリスチレン粉末、スチレンと(メタ)アクリル酸の共重合体樹脂粉末、ベンゾグアナミン樹脂粉末、ポリ四弗化エチレン粉末、セルロース粉末、及びトリメチルシルセスキオキサン粉末等、並びにオルガノポリシロキサンエラストマー球状粉末またはこれを母粉末とする複合球状粉末を挙げることができる。球状粉末の平均粒子径は3~20μmが好ましい。3μmより小さいとべたつきを抑制する効果が見られず、20μmより大きいと却ってざらつきを生じる場合がある。球状粉末の配合量は特に限定されないが、好ましくは3~30質量%、さらに好ましくは7~20質量%である。
本発明の化粧料は、日焼け止め化粧料のみならず、日焼け止め効果を付与したファンデーション等のメーキャップ化粧料や化粧下地、毛髪化粧料(紫外線から毛髪や頭皮を保護するためのヘアスプレーやヘアトリートメント等の各種ヘア製品を含む)、噴霧型化粧料にも適用可能である。
熱反応率(%)=(熱処理後の吸光度積算値)/(熱処理前の吸光度積算値)×100
本発明の乳化化粧料では、熱反応率が100%以上、好ましくは103%以上、より好ましくは105%以上、さらに好ましくは110%以上、特に好ましくは115%以上を示す。
加熱時間は、熱による影響を的確に評価するために、1分以上とするのが好ましく、より好ましくは10分以上である。加熱時間の上限としては、特に限定されないが、通常は60分以下、好ましくは30分以下である。
調製した乳化化粧料を、疑似皮膚PMMAプレート(SPFMASTER-PA01)に2mg/cm2の量で滴下し、60秒間指で塗布し、15分間乾燥させて塗膜を形成した。未塗布のプレートをコントロールとして、前記塗膜の吸光度(280~400nm)を日立製作所社製U-3500型自記録分光光度計にて測定し、得られた測定データから熱処理前の吸光度積算値を求めた。
次いで、前記塗膜を有するプレートを恒温槽に置き、37℃、30分の加熱処理を行い、上記と同様に吸光度積算値を求めた。
熱照射前後の吸光度積算値の変化(熱反応率)を次式に従って算出した。
熱反応率(%)=(熱処理後の吸光度積算値)/(熱処理前の吸光度積算値)×100
各サンプルの熱反応率(%)の値は以下の表に併せて示す。
