영문 초록

This study concerned about Gemini type co-surfactant which has very interesting properties with new components. They were synthesized by reaction of diethylene glycol monoethyl ether and dicarboxylic acid. The structure could be comfirmed with FT-IR and 1H-NMR. Surface active properties such as surface tension, evaluated cmc, cloud point, emulsing power were measured respectively at given conditions. Their surface tensions in the aqueous solution were decreased to 33∼35 dyne/cm, which was lower than 39 dyne/cm of SDS, and their cmc values evaluated by surface tension method were 5.0×10-1∼ 7.5×10-1 mol/L. And the emulsifying power was excellent in jojoba oil. All of the synthesized Gemini surfactants possessed good water solubility and their cloud point were 48∼58 ℃. As results, Gemini surfactants which were synthesized are expected to be applied as O/W emulsifiers.
