Abstract

A surfactant composition is provided. The composition includes chemical structure represented by Formula (1): where R1 represents a hydrocarbon group, a substituted hydrocarbon group, an alkyl ester group, or an alkyl amine having from 4 to 28 carbon atoms, and R2 and R3 represent hydrocarbon groups having from 1 to 5 carbon atoms. Also provided is a composition including a brine comprising a total salinity of at least 20,000 mg/L and the chemical structure shown in Formula (1). Methods of making a composition including the chemical structure represented by Formula (1) are also provided.
