Abstract
Abstract Surfactant compounds of the formula ##STR1## wherein R 1 , R 2 and R 3 are, for example, straight chain, branched chain, or cyclic alkyl, alkenyl, aryl or alkaryl moieties, or wherein two R groups are joined in a ring structure; M is nitrogen or phosphorus; X is an anionic moiety such as sulfate or sulfonate; and n is an integer of from about 1 to about 20, are useful detergents.
