Pripravila sa séria 6 nových organických amóniových solí amfifilného charakteru, odvodených odamínalkoholu, všeobecnej štruktúry:CH3(CH2)9CH(OH)CH2N + (CH3)2R Br -R = C6 – C16Súčasťou syntézy uvedených zlúčenín je aj príprava 1-bróm-2-dodekanolu. Sledovali sa agregačnévlastnosti týchto látok vo vodných roztokoch, vyjadrené hodnotami kritickej koncentrácie tvorbymiciel (tab. 2) a antimikróbna aktivita, vyjadrená minimálnou inhibičnou koncentráciou (tab. 3),v závislosti na postupnom predlžovaní alkylového reťazca pri zachovaní základnej štruktúry (2-hyd-roxydodecyl a metyl, naviazané na kvartérny dusík).
