METHOD OF OBTAINING EMULSION COSMETIC PREPARATION Russian patent published in 2011 - IPC A61K8/06 

FIELD: medicine, pharmaceutics.

SUBSTANCE: invention relates to field of cosmetology and deals with technology of obtaining cosmetic preparations for skin care. Components are introduced simultaneously or successively at room temperature into installation with powerful hydroacoustic impact, in which components are dispersed and cavitation homogenisation of emulsion with further packing is carried out. Mode of resonance acoustic cavitation is formed inside flow mechanic fluctuation system-canal, generation of sound fluctuations being performed with amplitude exceeding threshold of acoustic cavitation for moving multiphase medium, consisting of mixed ingredients, minimum 2-3 times. Frequency and distance between canal 1 walls are connected with definite ratio.

EFFECT: method makes it possible to obtain finest monodisperse cream emulsions with nonomicrone size of disperse phase, which penetrate deep into skin, it also makes it possible to carry out emulcification in small volume (dozens of millilitres) for preparation of cream, for instance, by individual order.
