Carrier Effect of Polyglycerin Fattyacid Esters for Anti-oxidant Activities of Plant Extracts Having Anti-oxidant Abilities in O/W Emulsion Systems

Abstract

This study focused on the development of a new anti oxidant for O/W emulsions containing poly unsaturated lipids (evening primrose oil, kukui nut oil etc.) of cosmetic formulations.
In this study, we clarified that the anti-oxidant properties of plant extracts having anti-oxidant abilities are closely related to their partition behaviors in o/w emulsions and their anti-oxidant effectiveness are remedied with the addition of lipophilic polyglycerin fattyacid esters providing a carrier effect for the orientation of the anti-oxidants toward the oil/water interface.
And we concluded that lipophilic polyglycerin fattyacid esters are effective anti-oxidant enhancers for natural anti-oxidants in O/W emulsions.
