One of the popular formulations is W/O emulsion in cosmetics. W/O emulsions are usually light and silky skin feel water resistant, not sticky and not oily. But it is more difficult to develop stable W/O emulsions as the viscosity of W/O emulsions decreased as time went on.In this paper we tried to make stable W/O emulsions using polyglyceryl fatty acid esters. Polyglyceryl fatty acid esters are esters of fatty acid and polyglycerol and derivatives and very safe materials. In results, W/O emulsions using 2.0% polyglyceryl fatty acid esters are more stable than emulsions using silicon emulsifier. And in case of using 0.2% glyceryl behenate/polyglycetyl-6 octastearate by gelling agent in oil phase, manufactured more stable W/O emulsionsand in case of using 0.05% xanthan gum by gelling agent in water phase, manufactured more stable W/O emulsions. |
