The title compounds (4) (alkyl=n-C10H21, n-C12H25, n-C14H29 and n-C16H33), were prepared by reactions of N-alkyltaurines (3) with carbon disulfide, followed by ethylation with bromoethane (Scheme-1, Table-1). The critical micelle concentrations of their aqueous solutions were determined by surface tension and electric conductivity (Table-2, Fig.-1 and 2).Dispersion, emulsifying, and solubilization powers were also measured using calcium carbonate, liquid paraffin, and Orange OT, respectively (Fig.-4, 5, and 6). The results indicated good surface-active properties of (4), which became better with increasing alkyl chain length except for emulsifying power. Although the compounds (4) were inactive against the gram-negative bacterium, Escherichia coli, good inhibitory effects were observed against the gram-positive bacterium, Staphylococcus aureus and the fungus, Aspergillus oryzae, particularly in the cases of R 10- (4) and R 12- (4) (Table-3 and 4, Fig.-7).
