カルボキシビニルポリマー1(日本ルーブリゾール株式会社、商品名:カーボポール941)
カルボキシビニルポリマー2(和光純薬工業株式会社、商品名:ハイビスワコー105)
アルキル変性カルボキシビニルポリマー(日本ルーブリゾール株式会社、商品名:カーボポールETD 2020)
ナイロン末(東レ株式会社、商品名:SP-500、平均粒径5μm)
成分(B)の量に関して、実施例4では0.0001質量%であったのに対して、ほぼ同じ組成の比較例1では0質量%であった。このように両者の成分(B)の量の違いはわずかであった。
また、水酸化カリウムによりカルボキシビニルポリマーを中和した以外は、実施例10と同様にして組成物を得た。実施例13で得られた組成物のPHは6.0であり、ケーキング抑止性の評価は○(使用可能)であった。
上記の実施例1~13で調製された組成物170mlを円筒状のポリプロピレン(PP)製容器(容量200ml)に充填した。その後、23℃の環境下、上記容器を十分に振とうし、振とう直後の容器内の粉体の分散状態を目視にて確認し、以下の評価基準に従って評価した。
◎(優れる):振とうにより、均一に微分散し、凝集体が形成しない。
○(良好):振とうにより、均一分散した後、弱い凝集体と微分散の混在系を形成する。
△(不十分):振とうにより、均一分散するが、明らかな凝集体を形成する。
×(不良):振とうによっても均一に分散できず、振とう直後に粉体が沈降する。
なお、上記の表には示していないが、実施例1の組成において、成分(B)の配合量を0.01質量%に変更した組成の組成物(比較例4)、及び実施例1の組成において、成分(B)の配合量を0.1質量%に変更した組成の組成物(比較例5)を調製し、粒子分散性を同様に評価した。その結果、比較例4の評価は△(不十分)であり、比較例5の評価は×(不良)であることが分かった。この結果から、成分(B)の配合量(含有量)が本願の上限値(0.008質量%)を超えて多くなると、組成物の粒子分散性が悪化する傾向が見られることが分かった。
実施例1、6、10~12で調製された各組成物(約1ml)を被験者の前腕内側部に塗布し、塗布後のべたつきのなさを評価した。実施例12で調製された組成物と実施例1、6、10、11で調製された各組成物を比較して、実施例12で調製された組成物(比較基準)よりもべたつきがないと感じた人数を調査した。なお、評価試験は、温度23℃の部屋内で、被験者10名により実施した。
実施例1で調製された組成物をディスペンサー容器に入れ、前腕内側部に1回噴霧(約0.1ml)し、乾燥速度を調べた。
その結果、実施例1で調製された組成物は、1分以内に、触れた時に濡れた状態を感じない程度にまで乾燥し、優れた速乾性を示すことが分かった。
エタノールの配合量を25.0質量%、精製水の配合量を73.3質量%に変更した以外は、実施例1と同様にして組成物を作製した。次いで、上記と同様にして速乾性を調べた。
下記表3に示す処方に従ってデオドラント剤を調製し、得られたデオドラント剤を口径0.4mmの非エアゾール型のスプレー容器に充填して、非エアゾール型スプレー製品を製造した。
下記表3に示す処方に従って清涼化粧料を調製し、得られた清涼化粧料を口径0.4mmの非エアゾール型のスプレー容器に充填して、非エアゾール型スプレー製品を製造した。
