Description
モノマー、コア化合物、開始剤(過硫酸塩)、界面活性剤および水を30〜50%固形分の濃度で反応器に入れる。その混合物は超音波ホモジナイザーを用いて、開始温度35℃で撹拌され、次いで、75〜85℃に加熱され、発熱反応のために約95℃の最大温度に到達した。
様々な架橋およびシェル含量を有する以下の粒子を製造するために上記の手順が使用された。架橋剤(xl)および他のモノマーの量はシェルポリマーに対するものであり、シェルの量は粒子全体に対するものである。粒子B、CおよびE−Gのコアは、アボベンゾンおよびホモサラートを31:69の重量比で含んでおり、粒子Hのコアは33:67の重量比で含んでいた。
オプトメトリクス(OPTOMETRICS)SPF290インビトロ測定
概要:試験される日焼け止め剤はあらかじめ洗浄された8.3×10.2cm(3.25×4インチ)プロジェクタースライドカバーガラス(コダックcat#1402130)上に広げられ、日焼け防止指数(SPF)はSPF操作ソフトウェア(バージョン2.1)およびSPF290分析器(The Optometrics Group)を用いて推定される。
1.長さ4インチの片が3M TRANSPORE テープRの3インチロールから取り出され、装置と共に供給されるサンプルホルダー上に配置され、ホルダー上のこのテープ片を用いてその装置はゼロ値が設定された。
2.スライドガラスをその場に保持するために吸引プレートを使用して、1.0ミルまたは1.5ミルのいずれかのスペーサー湿式膜アプリケーター(Byk Gardner Company cat#SAR−5358)を滑らかな動きで、中程度の速度で用いて、均一な膜がそのスライドガラス上にドローダウンされる。ドローダウン速度は、その速度が膜の厚さおよびそれによりSPF値を達成するであろうように、決定から決定まで一貫していなければならない。
3.日焼け止め剤膜はガラス上で少なくとも20分間乾燥させられる。複数のサンプルが評価される場合には、サンプルのドローダウンは、それぞれのサンプルの乾燥時間が互い違いにされ、ドローダウン後の測定時間が一致しているように計画される。サンプルが乾燥させられる間に、オプトメトリクスSPF290分析器が運転開始する。その装置が稼働されたあと、少なくとも20分でその装置はテープのブランク片を用いて初期化される。
4.テープのブランク片はサンプルホルダー上に配置され、バックグラウンドとして紫外線吸収が測定される。(ソフトウェアは、サンプルの吸光度からこの吸光度を引いて、テープの吸光度の測定を回避する。)
5.石英ガラス上の膜が20分間乾燥させられた後、日焼け止め剤を有するそれぞれのガラスプレートはテープの上に配置され(膜側を上に)、次いでサンプルを有するホルダーが測定のためのビームの下に配置される。
6.サンプルはスライドガラス上の6つの異なる領域で測定される。6つの読み取り値の全てを記録した後、オプトメトリクスSPF290分析器は日焼け止め剤エマルションのインビトロSPF値を計算する。最終的なSPFはこれら6つの決定の平均である。
全てのSPF測定は、典型的な日焼け止め剤乳化手順で添加された同じ量のホモサラートおよびアボベンゾンを含む対照に対して正規化されている(手順および配合は下記を参照)。
日焼け止め剤は次の表に従って配合された。その製造には、典型的な実験室オーバーヘッドミキサー(CAFRAMO BDC2002)が使用された。使用された手順は、75℃に加熱された水性相、別個に混合され75℃にされた油相を用いて、この2相を混合し、撹拌しつつ冷却してエマルションを形成する日焼け止め剤製造の典型的なものであった。ミニ封入アボベンゾンの1つのサンプルは、日焼け止め剤製造に使用される典型的なエマルション法で添加された配合物中の等量のアボベンゾンを含む「対照」サンプルと共に評価された。
全てのSPF測定は、上述のように1.0%アボベンゾンを含む対照に対して正規化された。全てのサンプルは同じ量のホモサラートを含む。IDサンプルA〜Cのアボベンゾンは典型的な日焼け止め剤乳化手順で添加される。IDサンプルD〜Fにおいては、アボベンゾンは封入ポリマーで添加される。サンプルAにおけるアボベンゾンの量はサンプルDと同じであり、サンプルBはサンプルEと同じ量であり、サンプルCはサンプルFとアボベンゾンの量が同じである。
