In order to develop new methodologies that enable theproduction of physiologically more efficient multiple emulsionsystems, first we have set the aim to evaluate the variation in thecapacity of poly acrylic acid polymeric emulsifiers when usingthem in the production of emulsions including different lipophilicphase agents– non-drying, semi-drying and mineral oils. Emulsionstability characteristics have been determined using the classicalmethods of analysis: microscopy, centrifugation, viscosimetry, conductometry,potenciometry. It was identified, that oil concentrationof different composition (non-drying, semi-drying and mineral oils),when using emulsifiers PTR1, PTR2 and their mixtures, did nothave any significantly impact on the acidity of the emulsion.. Theconcentration of non-drying oils in the emulsion mostly affectedthe increase in the emulsion viscosity. In the emulsions containingolive oil at a temperatures of 80C and 380C emulsion droplets increasedgradually and up to smaller dimensions than in the emulsionswith a semi-dry (sunflower oil) or mineral (petroleum jelly) oil.The research results suggest that when producing emulsions fromnon-drying oils and using pemulen type emulsifiers it is possible toexpect to obtain the stable system of larger size emulsion dropletsthan in the emulsions produced under the same conditions fromsemi-drying or mineral oils. When producing emulsion systemsusing our methodology with the lipophilic phase of mineral oils, asystem of minimum size of emulsion droplets could be obtained,compared to the emulsions based on the other nature oils.
