Citric Acid
^s*2P<:' ι* <> - < \ -Ι Ν·
• Recent laboratory experiments have shown that the inclusion of 2% Citric Acid in concentrates containing 40% 2,4-D (free acid basis) amine salts will prevent precipitation by the metallic ions in hard water*. Since Citric Acid forms complexes with these ions efficiently· all'of the 2,4-D is fully available for its herbicidal action.
Tests performed in our laboratories showed Citric Acid to be a more efficient sequestering agent in many cases than other commonly used products, and as favorable in all cases.
Important savings and increased efficiency await the users of Citric Acid as a sequestering agent. It is available as Anhydrous Citric Acid, or as the U.S.P. product, the former product being the most economical buy. For samples of Citric Acid or detailed information on its use as a solubilizing agent for 2,4-D amine salts write today to: Chas. Pfizer & Co., Inc., 630 Flushing Avenue, Brooklyn 6, Ν. Υ.
*Based upon water of 1000 PPM hardness. For harder water the concentration must be proportionally increased.
