ABSTRACT:
Compositions containing surfactant compounds according to formula (I)in-line-formulae description="In-line Formulae" end="lead"?R4OCH2CH(OH)CR2R3ZR1 (I)in-line-formulae description="In-line Formulae" end="tail"?wherein Z is S, SO, or SO2, can have a range of equilibrium and/or dynamic surface tensions and a range of foaming performance attributes, depending upon the particular values of Z, R1, R2, R3, and R4. The compounds of formula (I) may be prepared by a process that includes reaction of a thiol with a glycidyl ether.
