また成分(A)は、本発明の透明固形洗浄剤を調製するときに、N-アシル酸性アミノ酸と上記塩を形成する物質(例えば、水酸化ナトリウム、水酸化カリウム、TEA等)と一緒に加えて中和し塩の形態としてもよい。さらに成分(A)は、未中和のN-アシル酸性アミノ酸を含んでいてもよい。
例えば、ラウリン酸、ミリスチン酸、パルミチン酸、ステアリン酸、オレイン酸、イソステアリン酸等や、それらの混合物である牛脂脂肪酸、ヤシ油脂肪酸、パーム核油脂肪酸等から誘導されるアシル基が挙げられ、ラウリン酸、ミリスチン酸、ヤシ油脂肪酸から誘導されるアシル基が好ましく、ラウリン酸、ミリスチン酸、ヤシ油脂肪酸から誘導されるアシル基が泡の持続性や低温使用性の点からより好ましい。
これらのうち、泡立ちやすすぎやすさ、保存安定性に優れたものを得る点で、アルカリ金属塩が好ましく、ナトリウム塩、カリウム塩がより好ましい。
また成分(B)は、本発明の透明固形洗浄剤を調製するときに、アシルグリシンと上記塩を形成する物質(例えば、水酸化ナトリウム、水酸化カリウム、TEA等)と一緒に加えて中和し塩の形態としてもよい。さらに成分(B)は、未中和のアシルグリシンを含んでいてもよい。
具体的には、N-ココイル(ヤシ油脂肪酸アシル)グリシンカリウム、N-ココイルグリシンナトリウム等が挙げられ、N-ココイルグリシンカリウム、N-ココイルグリシンナトリウムが好ましい。
ここで透明固形洗浄剤のpHは、1%水溶液(40℃)でのpHと定義される。
(A)が20重量部より少ない場合には、低温や高温で保存した場合には析出や軟化を起こすため、透明固形洗浄剤としての剤型が保てず、泡性能も不十分である。50重量部を超えると製造時にゲル化してしまい製造が不可能になる場合がある。
(B)が0.01重量部より少ない場合では、泡性能に十分な効果が発揮できず、4.5重量部以上では、製造時の着色や高温保存での安定性が悪くなる場合がある。
(C)が10重量部以下では、低温や高温保存での安定性が悪くなり、25重量部以上では、高温保存での安定性が悪くなり、泡立ちが悪くなる場合がある。
(D)が2重量部以下では、製造時のゲル化により製造が不可能であり、40重量部以上では、乾燥に時間がかかる場合がある。
例えばpHが6以下では、低温での安定性が悪くなり、7以上では、高温での安定性が悪くなることから上記範囲のpHで仕込む場合には安定性のよい透明固形洗浄剤を製造することができる。
例えば、セチルアルコール、ステアリルアルコール、ベヘニルアルコール、イソステアリルアルコール、オクチルドデカノール、オレイルアルコール、ミリスチルアルコール等の高級アルコール;ラウリン酸、ミリスチン酸、パルミチン酸、ステアリン酸、硬化牛脂脂肪酸、ヤシ油脂肪酸、パーム油脂肪酸等の高級脂肪酸およびその塩;トリメチルグリシン等の保湿剤;アニオン性界面活性剤、カチオン性界面活性剤、両性界面活性剤、非イオン性界面活性剤等の界面活性剤;植物油、動物系油脂、天然系油脂誘導体、鉱物系油脂、低級および高級脂肪酸エステル、N-アシルグルタミン酸エステル等の合成系油脂;シリコーン化合物;高分子物質;動植物抽出物;アミノ酸;核酸;ビタミン;酵素;抗炎症剤;殺菌剤;防腐剤;抗酸化剤;紫外線吸収剤;キレート剤;制汗剤;酸化染料;pH調整剤;パール化剤;等の化粧品原料基準、化粧品種別配合成分規格、医薬部外品原料規格、日本薬局方、日本薬局外医薬品成分規格、食品添加物公定書等の各種公定書記載の原料等が挙げられる。
表1~8に示す量(重量部)の各成分を混合し、この混合物を70~80℃に加熱して各成分を均一に溶解する。次いで、これを型に注入する。その後、これを冷却固化、乾燥熟成を経て、透明固形洗浄剤を得た。乾燥熟成は、多価アルコール、低級アルコールの配合量により異なるが、20日~2か月程度行った。pHの調整は水酸化ナトリウムを適宜添加して行った。
