Objectives. The study aimed to analyze the current antiseptics and disinfectants, explore the possibility of synthesizing various antiseptics including oligohexamethylene guanidine hydrochloride (OHMG-HC) using microfluidic technology, and investigate the main synthesis parameters affecting the properties of the resulting product. Methods. This article presented a review of literature sources associated with investigations of antimicrobial resistance, the uses of agents based on polyhexamethylene guanidine hydrochloride, oligohexamethylene guanidine hydrochloride, and other salts, obained using modern synthesis technologies with microreactors. Results. The relevance of developing production technologies for the "OHMG-HC branched" substance was determined. The microfluidic method for the synthesis of polymers, and its application prospects for obtaining the target substance were compared with the existing methods. Advantages of the microfluidic method were indicated. Conclusions. Microreactor technologies allow for more accurate control of the conditions of the polycondensation reaction of the starting monomers and increase the yield and selectivity of the oligomers obtained, leading to an increase in the product purity and process efficiency, in contrast with other known methods. The use of microreactor technologies for the synthesis of branched oligohexamethylene guanidine hydrochloride products is a promising strategy.
