Versene™ 100 Chelating Agent product card banner

Dow North America

VERSENE™ 100 Chelating Agent

Applications: Processing & Packaging, Oil, Gas & Mining, Paper & Pulp

Product Families: Functional Additives, Builders & Chelators, Adjuvants & Formulation Ingredients

End Uses: Cleaners, Descalers, Textiles

VERSENE™ 100 Chelating Agent is an aqueous solution of the tetrasodium salt of ethylenediaminetetraacetic acid. Na4EDTA is the strongest, most versatile, and widely used chelant for controlling metal ions over a broad pH range in aqueous systems. It will not chelate monovalent metal ions such as sodium or potassium, but will chelate most multivalent metal ions (e.g., Fe, Cu, Mn, Ca, Mg, Zn) in a 1:1 molar ratio. The chelation reaction is virtually instantaneous in most cases. Calcium and other alkaline earth metals are most effectively chelated above pH 4. Na4EDTA chelates most transition metals below pH 12. VERSENE 100 is completely miscible with water, but is not soluble in organic systems. Na4EDTA is stable under widely varying conditions of temperature, acidity, alkalinity, and the presence of other chemicals. Na4EDTA is attached, however, by strong oxidizing agents such as hypochlorite bleach. In some applications, Na4EDTA can be reclaimed for reuse.

Tergitol™ L-61 Surfactant product card banner

Dow North America

TERGITOL™ L-61 Surfactant

Applications: Processing & Packaging, Chemical & Industrial Manufacturing, Oil, Gas & Mining

Product Families: Additives, Dispersing & Wetting Additives, Foam Control

Chemical Family: Diols, Glycols, Polyols

End Uses: Metalworking Fluids, Automatic Dishwash, Cleaners

Nonionic surfactant, efficient foam control agent because of its low foam characteristics, inverse water solubility, high thermal and chemical stability, with good steric stabilization. It is used in foam control processes such as fermentation of monosodium glutamate, lactic and citric acids; food processing; food washing; water treatment; and metal working products. Low surface tension makes it a particularly efficient rinse aid and low foam wetting agent in auto dish detergents, industrial and institutional cleaning, and in cleaning-place (CIP) applications such as food, dairy, and brewery cleaning. It can be used in oilfield drilling and production formulations. Benefits Efficient foam control agent Wetting agent High thermal & chemical stability Good steric stabilization Easily rinsed from surfaced
