Abstract
Abstract DETERGENT COMPOSITIONS CONTAINING REVERSED ZWITTERIONIC COMPOUNDS HAVING A NEGATIVELY CHARGED CENTER ADJACENT A HYDROPHOBIC CHAIN AND A POSITIVELY CHARGED CENTER REMOVED BY 2 TO ABOUT 4 CARBON ATOMS FROM THE NEGATIVELY CHARGED CENTER ARE DISCLOSED. THESE COMPOUNDS HAVE THE FORMULA R-Z-R1-X WHERIN R IS AN ALIPHATIC RADICAL, E.G., ALKYL OR ALKENYL, CONTAINING FROM ABOUT 10 TO ABOUT 20 CARBON ATOMS; Z IS A NEGATIVELY CHARGED RADICAL SELECTED FROM THE GROUP CONSISTING OF PHOSPHATE, PHOSPHONATE, AND PHOSPHINATE RADICALS; R1 IS AN ALKYLENE RADICAL CONTAINING FROM 2 TO ABOUT 4 CARBON ATOMS; AND X IS A POSITIVELY CHARGED RADICAL SELECTED FROM THE GROUP CONSISTING AMMONIUM AND TERIARY SULFONIUM RADICALS; SAID AMMONIUM RADICAL HAVING THE FORMULA -N(+)(-R2)(-R3)-R4 WHEREIN R2, R3 AND R4 ARE SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, METHYL, AND ETHYL; SAID TERTIARY SULFONIUM RADICAL HAVING THE FORMULA -S(+)(-R5)-R6 WHEREIN R5 AND R6 ARE SELECTED FROM THE GROUP CONSISTING OF METHYL AND ETHYL.
