Unique interfacial properties of a homologous series of novel triple-chain amphiphiles bearing three anionic head groups derived from 1,1,1-tris(hydroxymethyl)ethane

Unusual behaviour in which the critical micelle concentration (CMC) values in water for a homologous series of the title amphiphiles increased with an increase in the number of carbons of the lipophilic alkyl chains was observed when these data were obtained by the common surface tension method using a Wilhelmy tensiometer.
