1000mLセパラブルフラスコに、天然系高分子化合物からなるゲル形成剤である寒天粉末(伊那食品工業製;AX−200)30.0gを秤量し、イオン交換水を870.0g仕込み、アンカー式攪拌機で攪拌しながら80〜90℃にてゲル形成剤を加熱溶解し、次いでその溶液に気泡調整剤であるラウリン酸カリウム10%水溶液を96.6g、ステアリン酸カリウム10%水溶液を3.4g添加し、全質量を1000gとした。
気泡調整剤の種類を、表1に示すように変更した以外は実施例1に示す調製方法にてハイドロゲル粒子を得た。
気泡調整剤の種類と量を変更した以外は実施例1に示す調製方法にてハイドロゲル粒子を得た。
気泡調整剤の添加を行わなかった以外は実施例1に示す調製方法にてハイドロゲル粒子を得た。
(1)洗浄液の調製
ラウリン酸カリウム(和光純薬工業)10%、実施例1〜4又は比較例1〜2で得られたハイドロゲル粒子 各20%、イオン交換水70%を室温で均一に溶解・分散させる。
カーボンブラックを分散した下記に示す組成のモデル皮脂を調製し、その20mgを人工皮革上Φ25mmの円内に塗布し、その塗布部分に上記洗浄液を200mg滴下し、20回マッサージ洗浄を行い、水道水ですすぎ風乾した。

(マーカー)
カーボンブラック(三菱化学(株)製) 5 部。
そして処理前と洗浄前の色差と、処理前と洗浄後の色差より、次式に従ってモデル皮脂の洗浄率を算出し、ラウリン酸カリウム10%水溶液(ハイドロゲル粒子無し)の洗浄率を1とした相対値で、下記基準に照らして評価した。
・洗浄性の評価基準
×:洗浄率<ハイドロゲル粒子無しの洗浄率
△:ハイドロゲル粒子無しの洗浄率≦洗浄率<[ハイドロゲル粒子無しの洗浄率×1.1]
○:[ハイドロゲル粒子無しの洗浄率×1.1]≦洗浄率
<洗い流し性の評価法>
黒色人工皮革上に20%水溶液に調製したハイドロゲル粒子水溶液を0.1g静置した。上記黒色人工皮革を10°に傾けた後、スポイトで2gのイオン交換水を滴下した。滴下の様子をニコン製実体顕微鏡(SM2−2T)で観察し、滴下10秒後に視野内(約1cm)に残存するハイドロゲル粒子の数を数え以下の基準で洗い流し性を判定した。
×:視野内に10個以上のハイドロゲル粒子を認めた
△:視野内に1〜9個のハイドロゲル粒子を認めた
○:視野内にハイドロゲル粒子を認めなかった
*2 ハイドロゲル粒子全量に対する質量%
