The surface‐active properties and emulsification ability of sodium α‐sulfonated fatty acid esters, C m H 2m+1 CH‐(SO 3 Na)COOC n H 2n+1 , were studied as a function of the hydrophobic alkyl chainlength in the fatty acid (m=8−16) and the alcohol (n=8−18). As a result, it was discovered that sodium α‐sulfonated fatty acid esters have a structural effect on the Krafft point different from that of amphiphiles with short alkyl chains. Moreover, some of the α‐sulfonated fatty acid esters have quite low interfacial tensions, as well as non‐foaming properties, which depend upon the total (m+n) number of carbon atoms in the alkyl chains.
