Abstract: A surfactant composition containing: (a) from about 30 to about 70% by weight of an alkyl ether sulfate; (b) from about 0.1 to about 10% by weight of an alkyl polyglycoside of formula I: R1O(R2O)b(Z)a  I wherein R1 is a monovalent organic radical having from about 6 to about 30 carbon atoms; R2 is a divalent alkylene radical having from 2 to 4 carbon atoms; Z is a saccharide residue having 5 or 6 carbon atoms; b is a number having a value from 0 to about 12; a is a number having a value from 1 to about 6; and (c) from about 0.1 to about 10% by weight of a salt, all weights being based on the total weight of the composition.

Abstract: The use of selected cation exchange resins to remove dissolved multivalent cations ions such as iron, zinc, and chromium from used autodeposition compositions permits reuse of the autodeposition compositions without the need for added surfactant and without developing any undesirable graininess or other texture in the coatings formed. Iminodiacetate cation exchange resins are very effective for removing iron ions when they are the only multivalent ions to be removed, and can be efficiently regenerated with 0.5 to 4% by weight aqueous hydrofluoric acid. By proper choice of other cation exchange resins and operating conditions, zinc can be selectively extracted from autodeposition baths containing both iron and zinc, and either iron or zinc can be selectively displaced from the loaded ion exchange resin.
