CAPB is available as viscous pale yellow solution that is used as a surfactant in personal care products. The name reflects that the major part of the molecule, the lauric acid group, is derived from coconut oil. Cocamidopropyl betaine to a significant degree has replaced cocamide DEA. ==Production== Cocamidopropyl betaine can be viewed as the combination of cocamide and glycine betaine. It is however prepared by combining chloroacetic acid with the amide derived from dimethylaminopropylamine and lauric acid: :CH3(CH2)10C(O)N(H)CH2CH2CH2N(CH3)2 + ClCH2CO2H + NaOH → CH3(CH2)10C(O)N(H)CH2CH2CH2N+(CH3)2CH2CO2− + NaCl + H2O 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cocamidopropyl betaine」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
