ZWITTERIONIC POLYSILOXANE COMPOSITIONS ABSTRACT A zwitterionic composition useful as a surface active agent in aqueous solutions is disclosed. Said composition is represented by the general formula R'(CH3)2Si-O[SiO(CH3)2]w[SiCH3R-O]xSi(CH3)2R' where w is 0 to 50, x is 1, 2, 3, 4 or 5. R' denotes a methyl radical or an R radical, x + w is less than or equal to 50, and R denotes a monovalent zwitterionic radical of the general formula - (CH2)yN+(R")2(CH2)zSO3- where y is 1, 2 or 3, z is 3 or 4, and R" denotes an alkyl radical with 1 to 6 carbon atoms.
