초록

Methoxy polyoxyethylene dodecanoate류(C₁₁H₂₃COO(CH₂CH₂O)nCH₃)는 고체촉매를 이용하여 지방산 메틸에스테르에 에틸렌옥사이드를 부가시켜 얻어지는 비이온성 계면활성제의 일종이다. 이들은 지방알코올을 이용한 비이온성 계면활성제 polyoxyethylene dodecyl ether류(C₁₂H₂₅COO(CH₂CH₂O)nH)보다 경제성이 높은 이점을 가지고 있다. 이 연구는 이들 두 종류의 비이온성 계면활성제에 대하여 비이온성 계면활성제/물/오일의 3성분계에서 일어나는 상거동에 관련된 오일의 가용화량과 phase inversion temperature(PIT)에서의 계면장력 및 세정성을 비교하여 methoxy polyoxyethylene dodecanoate의 세제용 비이온성 계면활성제로서의 적용 가능성을 확인하기 위해 수행하였다. Methoxy polyoxyethylene dodecanoate는 3성분계의 상거동에서 hexadecane에 대해 10∼18%의 오일가용화량을 나타내므로서 polyoxyethylene dodecyl ether보다 약 6%의 높은 가용화력을 보여주었다. 또한, 각각의 PIT 조건에서 methoxy polyoxyethylene dodecanoate는 0.0124∼0.0176 dyne/cm, polyoxyethylene dodecyl ether는 0.0130∼0.0163 dyne/cm의 계면장력을 나타내었고 세정력에 있어서는 methoxy polyoxyethylene dodecanoate는 82.1∼83.2%, 그리고 polyoxyethylene dodecyl ether는 78.5∼80.4%로 methoxy polyoxyethylene dodecanoate가 polyoxyethylene dodecyl ether에 비해 높은 세정성을 나타내었다. methoxy polyoxyethylene dode-canoate의 우수한 세정 성능은 polyoxyethylene dodecyl ether에 비해 다소 높은 오일가용화력과 이에 관련된 PIT에서의 계면장력 저하효과에 기인된 것으로 판단된다.

Methoxy polyoxyethylene dodecanoates are a kind of nonionic surfactants obtainable from reaction of fatty acid methyl ester with ethylene oxide utilizing a solid catalyst. Methoxy polyoxyethylene dodecanoates have economical advantage compared with polyoxyethylene dodecyl ethers using fatty alcohol. In this work, the solubilizing capacity concerned with phase behavior of ternary systems composed of nonionic surfactant/water/oil, interfacial tension and detergency at the phase inversion temperature(PIT) were investigated and compared with those of polyoxyethylene dodecyl ethers in order to confirm the applicability of methoxy polyoxyethylene dodecanoates in the detergents. Methoxy polyoxyethylene dodecanoates showed the solubilizing capacity of 10∼18% for hexadecane which were about 6% higher than polyoxyethylene dodecyl ethers. At the PIT condition, methoxy polyoxyethylene dodecanoates' interfacial tension were 0.0124∼0.0176 dyne/cm while polyoxyethylene dodecyl ethers have the value of 0.013∼0.0163 dyne/cm and methoxy polyoxyethylene dodecanoates showed higher detergency of 82.1∼83.2% than polyoxyethylene dodecyl ethers of 76.5∼77.3%. The good detergency performance of methoxy polyoxyethylene dodecanoates would be due to the higher oil solubilizing power and lower interfacial tension than polyoxyethylene dodecyl ethers at the PIT condition.
