Abstract
Description
(a)フッ素処理水酸化アルミニウム被覆平板状粉体
本発明に用いられる(a)フッ素処理水酸化アルミニウム被覆平板状粉体(以下、単に「(a)成分」と称する場合がある)は、セリサイト、マイカなどの平板状粉体の表面に水酸化アルミニウムを析出させ、さらにフッ素基を付与して撥水性・撥油性をもたせるようにしたものを広く意味する。
本発明の(b)20mN/m以上の表面張力値を有する油性成分(以下、単に「(b)成分」と称する場合がある)は、1種または2種以上の油性成分からなり、油性成分全体の表面張力値が20mN/m以上(対大気)のものを指す。また、21mN/m以上、23mN/m以上、あるいは25mN/m以上の表面張力値を有する油性成分がより好ましい。(b)成分の表面張力値が20mN/m未満であると、(b)成分が粉末に容易に濡れるために、(b)成分を良好な粉末状形態とすることができない。
本発明に用いられる(c)45mN/m以上65mN/m以下の表面張力値を有する水性成分(以下、単に「(c)成分」と称する場合がある)は、化粧料に一般的に配合される品質の蒸留水、イオン交換水、精製水に各種保湿剤や薬剤等を溶解した水性成分であって、表面張力値が45mN/m以上65mN/m以下、好ましくは47mN/m以上65mN/m以下の水性成分を指す。ここで、「(c)成分の表面張力値」とは、液状をなす(c)成分全体の表面張力を、表面張力測定装置DCAT(英弘精機社製)を用いたウィルヘルミプレート法により測定した値をいう。(c)成分全体としての表面張力値が前記範囲を満足する限りにおいて、(c)成分の構成成分としての各水性成分が前記表面張力値の範囲を満たさないものであっても用いることができる。
(c)成分の表面張力値が45mN/mより小さい場合には、衝撃により容易に転相(粉体が液体の中に分散された状態)し、空気を含むペースト状になり、(a)成分で安定に粉末化するのが難しくなる。65mN/mを超える場合には、組成物を肌上に塗擦した際の肌へのなじみが悪くなる。
本発明の粉末状組成物は、(a)成分に油相である(b)成分を噴霧混合したのち、続けて(c)成分を噴霧する工程により調製される。なお、油相および水相の噴霧はどちらが先でもよい。

紫外線吸収剤を含む基剤を調製し、PMMAプレートに一定量を塗布し、UVスペクトルを測定した。このプレートを水洗し1分後にUVスペクトルを測定し、水洗前を1としたときのスペクトルの積分値の比を算出した。
白金製のウィルヘルミプレートを用い、表面張力測定装置DCAT(英弘精機社製)にて表面張力値を測定した。
調製した基剤1gを30mlの樹脂容器に入れ、ペイントシェーカーで振とうさせ、ペースト状態になるまでの時間を測定した。ペースト状態になるまでの時間が長いほど耐衝撃性が高いことを示す。
調製した基剤3gを30mlの樹脂容器に入れ、約30cm×20cm×10cmのダンボール箱にパッキンなしで10個を入れ、東京−大阪間をトラック便で往復輸送した。1個以上ペースト状になっていた場合には、不合格(不良)とした。
下記表1に示す組成で粉末状化粧料を調製した。前記試験方法により、各化粧料について粉末化の可否、使用性(きしみ感のなさ、みずみずしさ、なじみのよさ)、耐水性、ペーストになるまでの時間(耐衝撃性)、輸送テストを評価した。なお、表1中のフッ素処理マイカは「EPF MICA S」(大東化成工業社製)を用い、フッ素処理合成酸化チタンは「FSA−3 TiO2 CR−50」(大東化成工業社製)を用い、シリコーン処理タルクは「SA−タルク JA−13R」(三好化成工業社製)と「SA−タルク JA−46R」(三好化成工業社製)を混合して用いた。
