電解質對維他命E及K1在表面活性劑溶液中溶解的影響

脂溶性維他命廣泛應用於醫藥、食品與化妝品的製備。我們使用一系列膽鹽、陰離子型、陽離子型、兩性離子表面活性劑，加入電解質氯化鈉 (NaCl) 於表面活性劑溶液中溶解維他命E，可以使其溶解度大幅提高。另以Huls B433（已商業化的表面活性劑，多用於增進原油採油效率）加入氯化鈣 (CaCl2) 可增進維他命K1 之溶解，並降低維他命K1與Huls B433之間的界面張力。本篇研究中，使用動態光散射法、紫外光吸收光譜、濁度與肉眼觀察來研究加入電解質對乳化液系統的影響，並透過動態界面張力儀瞭解維他命K1與Huls B433之間的界面現象，進而對維他命E及維他命K1在表面活性劑溶液中溶解做一更深入的瞭解。我們發現加入電解質的濃度有一個最適當的濃度來增進維他命E與維他命K1 溶油的效率。溶解維他命K1及降低其與Huls B433的界面張力與原油實驗的規則--偏愛大表面活性劑微胞粒徑有關。加入氯化鈣的Huls B433表面活性劑溶液溶入維他命K1時可以獲得65nm粒徑大小的乳化液粒徑。

Fat-soluble vitamins have been extensively used in the preparation of medical, food and cosmetic products. To significantly increase the solubility of vitamin E, a series of bile salts, anionic, cationic and zwitterionic surfactants in electrolyte sodium chloride (NaCl) is used. Similarly using Huls B433, a commercial surfactant system to use in crude oil enhanced oil recovery, increases the solubility of vitamin K1. This research studies the effect of electrolyte-added surfactant solution on the emulsion, using techniques including dynamic light scattering, Ultraviolet absorption spectroscopy, turbidity, and visual observation. The study provides a further understanding of the dissolved vitamin E and vitamin K1. There an optimum electrolyte concentration of the exists solution to increase solubility of vitamin E and K1. The dissolution of vitamin K1 and its decrease in interfacial tension with the Huls B433 surfactant system follows both the experimental rules of crude oil and the preferred larger surfactant micelles.
