Abstract

Abstract: The stability of anionic‐cationic surfactant solutions and the antimicrobial properties of novel N, N ‐dimethyl‐ N ‐[3‐(gluconamide/lactobionamide)]propyl‐ N ‐alkylammonium bromides (CnDGPB and CnDLPB), N ‐methyl‐ N ‐hydroxyethyl group‐ N ‐[3‐(gluconamide)‐propyl]‐ N ‐alkylammonium bromide (CnMHGPB) and star‐shaped gluconamide‐type cationic surfactants N ‐dodecyl‐ N, N ‐bis[(3‐d ‐gluconylamido)propyl]‐ N ‐alkylammonium bromide (CnDBGB) were investigated. Mixed stability in combination with sodium n ‐alkylbenzenesulfonate (LAS) was determined via transmittance; stability is achieved when percent transmittance was greater than 90 %. Transmittance results suggest that these cationic surfactants can form stable solutions with anionic surfactants over a broad concentration range. The inhibition activity of C n DBGB is the best among the three kinds of glucocationic surfactants. Antimicrobial activity of C12 surfactants was the best, C14 was the second and C10 was the worst. Moreover, antibacterial activity of glucose‐based cationic surfactants was greater than lactose‐based cationic surfactants.
