Abstract
Anionic acid-labile surfactants may generally comprise compounds represented by the formulas: and wherein R1 is independently selected from —(CH2)0-9CH3, R2 is selected from the group consisting of —H and —(CH2)0-5CH3, Y is an anion, X is a cation, and n is an integer from 1 to 8. Methods of making and using the anionic acid-labile surfactants are also disclosed.
