A zwitterionic composition useful as a surface active agent in aqueous solutions. Said composition represented by the general formula n Rʹ(CH₃)₂Si-O[SiO(CH₃)₂] w [SiCH₃R-O] x Si(CH₃)₂Rʹ nwhere w is 0, to 50, x is 1, 2, 3, 4 or 5, Rʹ 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 n -(CH₂) y N⁺(Rʺ)₂(CH₂) z SO₃⁻ nwhere y is 1, 2 or 3, z is 3 or 4, and Rʺ denotes an alkyl radical with 1 to 6 carbon atoms. |
