Abstract

This study is concerned with coemulsifier which is better emulsifiable properties than emulsifier itselves' use only. It's compound was synthesized by esterification of propylene glycol and succinic acid. The structure of them was comfirmed with FT-IR and $^1H$-NMR. Surface active properties with surface tension, cmc, emulsing power were tested respectively at given conditions. Their surface tensions in the aqueous solution was decreased to 33-35 dyne/cm and their cmc was evaluated by surface tension method. And it's emulsifying power was excellent in jojoba oil. As results, the synthesized dipropylene glycol succinate is expected to apply as O/W coemulsifier.

유화제만을 사용하는 것 보다 더 좋은 유화특성을 갖는 유화보조제에 관한 연구이다. 그 화합물들은 숙신산과 프로필렌글리콜과의 에스테르화 반응에 의하여 합성되었다. 그 구조는 FT-IR과 $^1H$-NMR 분석으로 확인하였다. 표면장력, 임계미셀농도(cmc), 유화력 등 계면특성을 각각 주어진 조건하에서 시험하였다. 그 수용액의 표면장력은 33-35 dyne/cm 이었고, cmc는 표면장력법에 의하여 산정하였다. 그리고, 유화력은 호호바오일의 경우 우수하였다. 결과적으로 합성한 디프로필렌글리콜 숙시네이트는 O/W 유화에서의 유화보조제로서 응용이 기대된다.
