ABSTRACT:
Compositions containing surfactant compounds according to formula (I)in-line-formulae description="In-line Formulae" end="lead"?ROCH2CH(OH)CR1R2ZCR1R2CH(OH)CH2OR,  (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, R, R1, and R2. The compounds of formula (I) may be prepared by a process that includes reaction of a sulfide source such as a metal sulfide or bisulfide with an alkyl glycidyl ether. The compounds may be useful in any of a broad range of applications requiring the use of a surfactant.
