Amphoteric surfactants disinfection

Consider using anionic and amphoteric surfactants to enhance the performance of antimicrobial agents, since they make the cell wall of microorganisms more permeable to disinfectants. 

Owing to their compatibility with cationic biocides, amphoteric and amine oxide surfactants continue to be used widely in the development and formulation of disinfectants and sanitizers for personal care, household, industrial, and institutional markets. For instance, substituted imidazoline amphoteric surfactants, in combination with didecyl dimethyl ammonium chloride, have been found to display unexpected synergistic irritation reduction compared to formulas with alkyl dimethyl benzyl ammonium chlorides [57]. Also, imidazoline derivatives and betaines are known to impart moderate cleansing without causing skin roughness, stickiness, or irritating reactions with cationic disinfectants [58], Amphoteric surfactants are also suitable for use in antimicrobial medications requiring subcutaneous, cutaneous, or mucosal membrane administration [36]. 

The peracid salt may be used as a general purpose disinfectant, disinfectant for hospitals, food industry and institutions. It is compatible with many nonionic, cationic, anionic and amphoteric surfactants. Recommended use concentrations for the treatment of surfaces according to tests with Enterococcus faecium. Pseudomonas aeruginosa, Staphylococcus aureus,. Proteus mirabilis, Candida albicans (source LONZA) 0.5% (60min) for clean surfaces, 1.0% (60 min) for dirty surfaces... 

Anionic and amphoteric surfactants are not disinfectants per se, but they can be used as vehicles for other active ingredients. 

Amphoteric surfactants could be considered as disinfectants when in their cationic form, but only the cocoamidopropyl betaines have been shown to behave as true disinfectants. Their biocidal activity increases with the number of secondary amine groups.
