本発明の化粧料組成物(以下、単に「本発明の組成物」とも称する)は、
極性油及び下記式(I)の構造を有する化合物Iを含む、化粧料組成物であって、
極性油及び化合物Iの合計100質量部に対して、化合物Iが、0.01質量部以上50質量部以下である、
化粧料組成物
である。
本発明の組成物は、極性油を含む。ここで、「極性油」とは、シリコーン油以外の、化粧料に使用可能な油分の中で極性が高い油分を指し、例えば、IOB値が0.10以上、0.11以上、0.12以上、又は0.13以上のものを指す。また、本発明にかかる極性油のIOB値は、2.0以下、1.5以下、1.0以下、0.50以下、0.45以下、又は0.40以下であってよい。なお、IOB値とは、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-」、p.11~17、三共出版、1984年発行参照)。
本発明の組成物は、化粧料又はその原料として好適に使用することができる。すなわち、本発明は、特に、日焼け止め化粧料組成物を提供する。
本発明の化粧料組成物は、上述した成分以外に、化粧品分野において使用することができる任意の水性成分又は他の成分を更に含んでもよい。その他の成分としては、例えば、上述した極性油以外の油分、紫外線散乱剤粒子、紫外線吸収剤、界面活性剤、保湿剤、金属イオン封鎖剤、天然及び合成高分子、水溶性及び油溶性高分子、各種抽出液、有機染料等の色剤、防腐剤、酸化防止剤、色素、増粘剤、pH調整剤、香料、冷感剤、制汗剤、殺菌剤、皮膚賦活剤、その他の薬剤、並びに各種粉体等の他の成分を更に含んでもよいが、これらに限定されない。
本発明の組成物は、本発明の効果を損なわない限り、上述した極性油以外の油分を更に含んでよい。この場合、極性油及び極性油以外の油分の合計100質量部に対して、極性油以外の油分は、90質量部以下、80質量部以下、70質量部以下、60質量部以下、50質量部以下、40質量部以下、30質量部以下、又は20質量部以下であってよく、また0.1質量部以上、0.5質量部以上、1.0質量部以上、5.0質量部以上、又は10質量部以上であってよい。
シリコーン油とは、化粧料に使用可能な油分の中で、シロキサン結合による主骨格をもつものを指す。なお、「シロキサン結合による主骨格をもつもの」であって、かつ上述した「紫外線吸収剤」として使用できるものは、ここでいう「シリコーン油」から除外される。
本発明において、炭化水素油は、上述した極性油以外の、炭化水素油を指す。
本発明の組成物は、例えば紫外線防御効果を向上させる観点から、紫外線散乱剤粒子を更に含んでよい。
