Abstract

The invention provides a W / O / W type multi-structure emulsion which comprises the following components by weight percent: 1-15% of oil phase, 1-5% of lipophilic emulgator, 2-20% of hydrophilic emulgator and the balance of water. A preparation method for the emulsion comprises the following steps: firstly, mixing the oil phase, lipophilic emulgator and hydrophilic emulgator and then heating to 75-90 DEG C, thereby acquiring a uniformly dispersed oil phase component; heating water to 75-90 DEG C, thereby acquiring an aqueous phase component; and homogenizing the oil phase component at the homogenizing rate of 13000-18000Kr / min, and meanwhile, adding the aqueous phase component, homogenizing for 3-10min and then controlling stirring and naturally cooling to room temperature, thereby acquiring the W / O / W type multi-structure emulsion prepared according to a PIC phase volume conversion method. The W / O / W type multi-structure emulsion acquired according to the method provided by the invention is uniform in grain size of the dispersing phase.

Description

technical field [0001] The invention belongs to the field of cosmetics and relates to an emulsion, in particular to a method for preparing a W / O / W multi-structure emulsion by a PIC phase volume transition method. Background technique [0002] Multiple emulsions are such a system that "in the dispersed phase droplets of the emulsion, there is another dispersed phase distributed in it". In the development process of new cosmetic formulations, multiple structure emulsions (W / O / W, O / W / O) is arguably one of the most promising ideal systems. Its advantages are mainly manifested in the following aspects: (1) Different active substances can be dissolved in three different phase areas separated by membranes (oil phase / water phase / oil phase, water phase / oil phase / water phase), and prevent their interaction. For example, W / O / W multiple structure emulsions can allow two different water-soluble active substances (such as proteins, enzymes and vitamins) and one oil-soluble active subst...
