An asymmetric organo-modified disiloxane surfactant having the formula: M1DM2 is disclosed, wherein M1 = (R1)(R2)(R3)SiO1/2 M2 = (R4)(R5)(R6) SiO1/2 and D = (R7)(Z) SiO2/2 where R1, R2, R3, R4, R5, R6 and R7 are each independently selected from the group consisting of 1 to 4 carbon monovalent hydrocarbon radicals, aryl, and a hydrocarbon group of 4 to 9 carbons containing an aryl group Z is a pendant hydrophilic ionic group selected from the group consisting of R8-RA, R9 Rc, and R10-Rz RA being an anionic substituent, Rc a cationic substituent or Rz a zwitterionic substituent on the D group, which are further defined in the specification, wherein the disiloxane surfactant has an enhanced resistance to hydrolysis between a pH of about 3 to about 12. The disclosure also relates to a composition comprising said asymmetric organo-modified disiloxane surfactant and a component selected from the group consisting of agricultural components, coating components, personal care components, home care components, oil or gas treating components, water processing components, and pulp or paper treating components. Further disclosed are aqueous emulsions where the discontinuous phase comprises water and the continuous phase comprises said composition mixture, or vice versa.
