[調製方法]
表2~9に示す組成に従い、洗い流すタイプのヘアコンディショナーを下記方法により調製した。具体的には、油性成分を溶解混合し、ポリオール類(多価アルコール又は糖アルコール)を加え混合、ゲル液晶を形成させ均一化する。ゲル液晶に(A)アクリル酸系ポリマーを加え、さらに均一混合する。その後、有機酸及び水溶性成分を溶解した水相を加え転相乳化した。さらに攪拌しながら室温まで冷却した。水酸化ナトリウムによりpH3.7に調整した。
なお、pH、粘度測定方法は下記示すとおりであり、得られたヘアコンディショナーについて、下記評価を行った。
測定条件
pH:pHメーター;東亜ディーケーケー株式会社製 HM-30G、測定温度;25℃
粘度:粘度計;TOKIMEC社製 BM型粘度計 No.4ローター 30rpm 20秒後、測定温度;25℃
(1)「髪のぱさつきのなさ」、「髪のなめらかさ」、「剤の伸び易さ」
最近2ヶ月以内に白髪染めを行った50才~60才で、髪のぱさつきやダメージを感じている女性30名が、各洗い流すタイプのコンディショナー組成物を7日間使用した(シャンプーはライオン(株)「植物物語 ハーブブレンド さっぱりさらさらタイプ」を使用)。「髪のぱさつきのなさ」、「髪のなめらかさ」、「剤の伸び易さ」の項目について評価した。結果を、良好と答えた人数により、下記基準に基づき示す。
〈評価基準〉
◎:良好と答えた者が30名中25名以上
○:良好と答えた者が30名中15~24名
△:良好と答えた者が30名中5~14名
×:良好と答えた者が5名未満
洗い流すタイプのヘアコンディショナーを50mLのPET(ポリエチレンテレフタレート)バイアルに充填し、40℃の恒温槽中で6ヶ月間保存した後に肉眼観察し、下記の評価基準に基づいて評価した。
〈評価基準〉
◎:分離、析出は見られない
○:ごく僅かに分離又は析出は見られるが、商品価値上問題は無い
×:完全に二層に分離している
