The invention relates to the field of cosmetology and for technology for obtaining cosmetic products for skin care.The method of simultaneous processing and obtaining cosmetic emulsion volumes, each of which has a different composition of the ingredients included in the oil and water phases, different emulsifiers and biologically active substances by placing the volume within the continuous-flow mechanical oscillation system channel system where the resonant acoustic cavitation behavior is implemented, characterized in that the volumes of ingredients having a rectangular profile are immersed in the fluid channel so that the acoustic wave from the wall of the channel falls perpendicular to the major edge of volume, and the material they are made of has a specific acoustic impedance being equal or close to the impedance of the liquid filling the channel system and to the impedance of the treated mixture of cosmetics, the amplitude of the ultrasonic resonance oscillations exceeds the threshold of acoustic cavitation for the mixture of ingredients that are currently being processed with the transmission loss through the walls of the volume and the optimum temperature of the mixture, and the processing time is determined experimentally for the required stability of cosmetic emulsions .The method takes the opportunity to obtain simultaneously several different cosmetic emulsions as the finest monodisperse cream emulsions with submicron size of the dispersed phase, it is effective at getting small volumes of the product, that allows to organize mass production of cosmetic products for personal use.
