http://www.niacet.com/sodium-diacetate.html NIACET Sodium Hydrogen Diacetate, or Sodium Diacetate, is a fine granular, non-toxic, crystalline material with a vinegar-like odor. It has been used in foam manufacture and in photography for controlling pH. Sodium Diacetate is excellent as a substitute for vinegar in dry flavor premixes. It is also effective as a mold and rope inhibitor similar to Calcium and Sodium Propionate. Made in the USA en-us images/pdf_download.gif http://www.niacet.com/sodium-diacetate.php sodium-diacetate/sodium-diacetate-base.php Sodium Diacetate is a fine granular, crystalline material with a vinegar-like odor. It is analogous to crystalline Sodium Acetate, 60% grade, except the water is partially replaced by acetic acid. Sodium Diacetate is a free-flowing, convenient, readily-available source of acetic acid and sodium acetate in granular form. It has been used in foam manufacture and in the photographic industry for controlling pH. For photographic use, it replaces the oxalic or citric acid formerly used for hardening, fixing and toning. Sodium Diacetate is excellent as a substitute for vinegar in dry flavor premixes. It is also effective as a mold and rope inhibitor similar to Calcium and Sodium Propionate.
