It has been reported that octamethylcyclotetrasiloxane (D4) and decamethylcyclopentasiloxane (D5) in the above are unlikely to increase with time. However, it is essential to add a quaternary ammonium surfactant, and if the emulsion of Patent Document 5 is added to a shampoo or the like containing an anionic surfactant as in the case of Patent Document 4, the stability may decrease. ..
- Patent Document 6 describes amino-functional organopolysiloxanes containing less than 0.1% by mass of octamethylcyclotetrasiloxane (D4) and decamethylcyclopentasiloxane (D5), quaternary ammonium surfactants, and nonionic surfactants. Emulsion compositions with agents and water have been reported.

[アミノ変性シリコーンのエマルジョン]
本発明のアミノ変性シリコーンのエマルジョンは、
(A)後述する一般式(1)で表されるアミノ変性シリコーン、
(B)ノニオン性界面活性剤 (A)成分の質量に対して5~100質量%、
(C)乳酸又は酢酸 (A)成分のアミノ基モル数に対して50~100モル%、
(D)水 (A)成分の質量に対して85~10,000質量%、
を含有し、かつ、25℃で6ヶ月保管した場合のオクタメチルシクロテトラシロキサン(D4)、デカメチルシクロペンタシロキサン(D5)およびドデカメチルシクロヘキサシロキサン(D6)のそれぞれの増加量が(A)成分の質量に対してそれぞれ3,000ppm未満であるアミノ変性シリコーンのエマルジョンである。
(A)成分であるアミノ変性シリコーンは下記一般式(1)で表され、25℃での粘度が200~100,000mPa・sであり、アミン当量が1,000~20,000g/molである。

ノニオン界面活性剤は、ポリオキシエチレンアルキルエーテル等のポリオキシアルキレンアルキルエーテル、ポリオキシエチレンポリオキシプロピレンアルキルエーテル、ポリオキシエチレンアルキルフェニルエーテル、ポリオキシエチレン脂肪酸エステル、ソルビタン脂肪酸エステル、ポリオキシエチレンソルビタン脂肪酸エステル、グリセリン脂肪酸エステルのようなノニオン界面活性剤等を挙げることができる。これらの具体例としては、ポリオキシエチレンオクチルエーテル、ポリオキシエチレンポリオキシプロピレンオクチルエーテル、ポリオキシエチレンノニルエーテル、ポリオキシエチレンデシルエーテル、ポリオキシエチレンポリオキシプロピレンデシルエーテル、ポリオキシエチレンラウリルエーテル、ポリオキシエチレンポリオキシプロピレンラウリルエーテル、ポリオキシエチレントリデシルエーテル、ポリオキシエチレンポリオキシプロピレントリデシルエーテル、ポリオキシエチレンセチルエーテルなどが挙げられる。また、官能基を有する反応性の界面活性剤を使用することも可能である。
(C)成分は乳酸又は酢酸である。また、乳酸および酢酸を互いに任意の割合で混合してエマルジョンに配合してもよい。後述の実施例のように複数回に分けて配合してもよい。
(D)成分の配合量は(A)成分の質量に対して85~10,000質量%であり、好ましくは85~500質量%である。上記下限値未満では、本発明のアミノ変性シリコーンのエマルジョンの粘度が高くなり、取り扱いにくくなる恐れがある。一方で、上記上限値超では、エマルジョン中のアミノ変性シリコーンの割合が少なく、毛髪化粧料や柔軟剤に本発明のアミノ変性シリコーンのエマルジョンを配合した時にすべり性や柔らかさといった効果が発揮されない恐れがある。
(E)成分は本発明のアミノ変性シリコーンのエマルジョンの任意成分であるが、(E)成分を配合することで、本発明のアミノ変性シリコーンのエマルジョンの粘度が低下し取り扱いやすくなる場合やアミノ変性シリコーンのエマルジョン中の、オクタメチルシクロテトラシロキサン(D4)、デカメチルシクロペンタシロキサン(D5)およびドデカメチルシクロヘキサシロキサン(D6)の経時の増加が抑制できる場合がある。また、(E)成分を配合した本発明のアミノ変性シリコーンのエマルジョンを毛髪化粧料や柔軟剤に配合すると保湿性を付与することができる。(E)成分は(A)成分の質量に対して1~20質量%含有することが好ましい。
(F)成分は本発明のアミノ変性シリコーンのエマルジョンの任意成分であるが、(F)成分を配合することで、本発明のアミノ変性シリコーンのエマルジョンの粘度が低下し取り扱いやすくなる場合がある。(F)成分は(A)成分の質量に対して0.1~3質量%含有することが好ましい。
本発明のアミノ変性シリコーンのエマルジョンの製造方法は従来公知の方法に従えばよい。具体的な調製方法の例は、主に以下に示す通りである。
(A)成分アミノ変性シリコーン、(B)成分ノニオン性界面活性剤、(C)成分乳酸もしくは酢酸、(D)成分の一部の水、必要に応じて(E)成分多価アルコール、および(F)成分アニオン性界面活性剤を混合、乳化し、せん断力下で撹拌した後に残りの(D)成分水で希釈し目的のアミノ変性シリコーンのエマルジョンとすることができる。
また、(A)成分の乳化が起こりにくい場合は、(A)成分、(B)成分、一部の(D)成分を混合、乳化し、せん断力下で撹拌した後に残りの(D)成分水で希釈しエマルジョンとした後、希釈したエマルジョンに(C)成分および必要に応じて(E)成分および(F)成分を配合し、撹拌することにより目的のアミノ変性シリコーンのエマルジョンとすることもできる。乳化処方の詳細の一例は以下の通りである。
上記の如くして得られたアミノ変性シリコーンのエマルジョンは、シャンプーやコンディショナー等の毛髪化粧料に極めて有用である。配合量としては、例えばアミノ変性シリコーンのエマルジョンは毛髪化粧料中に0.1~20質量%となる量が好ましく、さらに好ましくは0.5~10質量%である。配合量が上記下限値以上であれば、髪に対するコンディショニング効果が十分に得られ、上記上限値以下では、べたつきがなく、好ましい感触となる。
また、本発明のアミノ変性シリコーンのエマルジョンは柔軟剤や洗濯洗剤等の繊維処理剤にも極めて有用である。例えばアミノ変性シリコーンのエマルジョンは柔軟剤中に0.1~20質量%配合させることができ、好ましくは0.5~10質量%である。配合量が上記下限値以上であれば、風合いが低下する恐れが小さい。一方で、配合量が上記上限値以下であれば、保存時に黄変が生じる恐れが小さい。

乳化組成物(エマルジョン)1~9を水で約10倍に希釈し、乳化組成物1~5、7~9は粒径測定機(HORIBA製 LA960)、乳化組成物6は粒径測定機(ベックマンコールター製 N4 PLUS)で測定した値である。
乳化組成物1~9を25℃でpHメーター(HORIBA製 LAQUA)にて測定した値である。
乳化組成物1~9を25℃で回転粘度計(東機産業製、VISCOMETER TVB-10)にて回転数30rpmで測定した値である。
乳化組成物1~9を25℃で6ヶ月保管した際の乳化組成物中の環状低分子シロキサン(オクタメチルシクロテトラシロキサン(D4)、デカメチルシクロペンタシロキサン(D5)およびドデカメチルシクロヘキサシロキサン(D6))の成分(A)に対する増加量である(製造直後から6ヶ月保管後の成分(A)に対する環状低分子シロキサンの増加量)。
環状低分子シロキサンの測定方法は以下の通りである。
[成分(A)アミノ変性シリコーンおよび乳化組成物4、7~9]
アセトン10mLに少量の0.1gの測定サンプルを添加し、2時間程度振とうする。振とうによりアセトン溶液に環状低分子シロキサンを抽出させた後、上澄みのアセトン溶液をガスクロマトグラフィー(Agilent 7890B(アジレント・テクノロジー製))にて測定する。
[成分(A)アミノ変性シリコーンおよび乳化組成物1~3、5および6]
へキサン10mLに少量の0.1gの測定サンプルおよび脱水芒硝0.1gを添加し、2時間程度振とうする。振とうによりヘキサン溶液に環状低分子シロキサンを抽出させた後、上澄みのヘキサン溶液をガスクロマトグラフィー(Agilent 7890B(アジレント・テクノロジー製))にて測定する。
すなわち、(C)成分の配合量が本発明の範囲より少ない比較例1では、エマルジョンのpHが実施例のpHよりも高くなり、特に25℃で6ヶ月保管後の(D4)の量が大きく増加した。
本発明の(C)成分である乳酸又は酢酸の代わりにプロピオン酸又はリン酸を用いた比較例2~3でも、(D4)の量が大きく増加した。
サリチル酸を用いた比較例4では、ゲルが多く発生しそもそもエマルジョンを得ることができなかった。
下記組成のヘアトリートメント(pH4.0)に実施例1の組成物を配合し、常法により調製した。
