Abstract : The effective foam control life of silicone anti-foam compositions is extended in the patent by including aminoalkanesulfonic acids and their salts. Even greater anti-foam protection is provided by further adding a glycine compound or salt to the composition. Addition of the novel compositions of this invention to monoethanolamine scrubber solutions appreciably increases the effective life of such solutions over that possible using a silicone anti-foam agent alone.
