Abstract
Description
また、経時で粘度が上昇する場合も多くみられ、2鎖型のカチオン界面活性剤などを粘度上昇防止剤として用いるようなことも検討されてきたが、充分良好な安定性は得られていなかった(例えば、非特許文献2参照)。更に、皮膚内部からの水分蒸散を防ぐ(オクル―ジョン)効果も充分ではなかった。
また、皮膚内部からの水分蒸散を防ぐ目的で、セラミド類、ジアルキル4級アンモニウム塩またはリン脂質などの2鎖型化合物とステロール類を含む同様の製剤(例えば、特許文献1)や、リン脂質、ポリオキシエチレンステロールエーテル類、高級アルコールを含む製剤(例えば、特許文献2、非特許文献3)が用いられてきたが、リン脂質類は着色や匂いなどの問題点があり、セラミドには結晶が析出しやすいといった問題点があった。
(A)1種または2種以上の炭素数16以上の高級脂肪族アルコール及び/または高級脂肪酸25~50質量%
(B)下記一般式(I)で表されるポリオキシエチレンステロールエーテル40~70質量%
(I)
(ただし、一般式IでRはコレステロール及び/またはフィトステロール残基、nは5~20の整数を表わす。)
(C)下記一般式(II)で表されるポリオキシエチレンジアルキルエステル及び/またはエーテルを5~20質量%
(II)
(ただし、一般式IIでR1及びR2は炭素数16~24の直鎖脂肪族酸残基または直鎖脂肪族アルコール残基、nは4~15の整数)
からなり、水相に添加されてゲルを形成することを特徴とする。
また、上記のαゲル組成物に、窒素原子を有する2鎖型両親媒性物質をαゲル組成物中の有効分に対し0.1~10質量%含有することが好適である。
また、前記ゲル組成物は、前記の窒素原子を有する2鎖型両親媒性物質がリン脂質、レシチン、リゾレシチン、セラミド、ジアルキル4級アンモニウム塩から選ばれる一種または二種以上からなることが好適である。
また、前記αゲル形成用組成物において、(I)のポリオキシエチレンステロールエーテルは、疎水基としてフィトステロール、コレステロール、エルゴステロールを有するものが好適であり、ポリオキシエチレン鎖は5~30モルが好適である。例としては、ポリオキシエチレン(5モル)フィトステロール(例えば、日光ケミカルズ社製、Nikkol BPS-5)、ポリオキシエチレン(10モル)フィトステロール(例えば、日光ケミカルズ社製、Nikkol BPS-10)、ポリオキシエチレン(20モル)フィトステロール(例えば、日光ケミカルズ社製、Nikkol BPS-20)、ポリオキシエチレン(30モル)フィトステロール(例えば、日光ケミカルズ社製、Nikkol BPS-30)、ポリオキシエチレン(10モル)コレステロール(例えば、日本エマルジョン社製、Emalex CS-10)などが挙げられる。配合量としては全有効分中40~70質量%が好適である。
また、皮膚外用剤組成物中に前記αゲル組成物は任意の量を配合することができるが、一般的には皮膚外用剤中でαゲル組成物中の有効分として0.1~20質量%が好適である。
本発明にかかるαゲル組成物は、1種または2種以上の炭素数16以上の高級脂肪族アルコール及び/または高級脂肪酸25~50質量%とポリオキシエチレンステロールエーテル40~70質量%とポリオキシエチレンジアルキルエステル及び/またはエーテルを5~20質量%を70~80℃にて溶融させ、これに70~80℃のイオン交換水を40~90質量%の割合で加え撹拌後、冷却することにより得られる。また、1種または2種以上の炭素数16以上の高級脂肪族アルコール及び/または高級脂肪酸25~50質量%とポリオキシエチレンステロールエーテル40~70質量%とポリオキシエチレンジアルキルエステル及び/またはエーテルを5~20質量%を70~80℃にて溶融させた後、リン脂質、レシチン、リゾレシチン、セラミド、ジアルキル4級アンモニウム塩などの窒素原子を有する2鎖型両親媒性物質を加えて溶融させ、これに70~80℃のイオン交換水を40~90質量%の割合で加え撹拌後、冷却することにより得られる。なお、αゲルとは、一般には高級脂肪族アルコールと親水性界面活性剤が水中で形成する会合体であって、α構造(福島正二著「セチルアルコールの物理化学」フレグランスジャーナル社)をとるゲルを意味する。
本発明では、上記3成分のみでαゲルを構築できるが、肌荒れ改善などの目的で必要に応じて、リン脂質、レシチン、リゾレシチン、セラミド、ジアルキル4級アンモニウム塩などの窒素原子を有する2鎖型両親媒性物質を併せて配合することもできる。
