Abstrakt		On the basis of physical characteristics determination of silicone surfactant, polysiloxane-polyalkylen-polyether copolimer, the composition of semisolid emulsion systems was designed. The optimal concentration of surfactant (5 per cent) in bases (containing different ratio of white petrolatum and purified water) was defined through critical micelle concentration determination in liquid paraffin. The method of cold emulsification enabled the formulation of physically stable systems proved using centrifuging (at 3000, 5000 RPM) isothermal (room and elevated temperature) and nonisothermal conditions during agerng (cycles of temperature burdening) and following viscosity in the period of three months.
