Development of Water Soluble Tocopherol Emulsion Using Surfactants

계면활성제를 이용한 수분산 Tocopherol 유화물의 개발

  • Published : 2008.11.28

Abstract

This study was carried out to make water-soluble tocopherol emulsion which can be applicable directly in water. The molecular weight of tocopherol was 340 to 360 and tocopherol emulsion model was decided as O/O/W/W type. In correlation between stability of emulsion and surface tension, the stability in surface tension of emulsion was from 40 to 46 dyne/cm. In the case of lower than 40 dyne/cm of surface tension, the stability of the emulsion was lower. Lipophilic surfactants, especially for a polyglycerine polyricinoleate in 20%, 30% and 40% tocopherol emulsion, was the most effective in emulsion stability. A higher stability of the emulsion among hydrophilic surfactants in the tocopherol emulsion was obtained in the following order; polyglycerine monostearate> polyglycerine monooleate> polyoxyethylene (20) sorbitan monooleate$\geq$ polyoxyethylene (20) sorbitan monolaurate.
