Description

Sodium tripolyphosphate is used in water softening, heavy-duty fabric washing, automatic dish washing, drilling fluid cleaning and liquid cattle feed supplements. It is also used as a peptizing, emulsifying, dispersing agent and as a hydrogen peroxide solution stabilizer. It acts as a preservative for seafood, meats, poultry, and animal feeds. It finds application as a polyanion crosslinker in polysaccharide based drug delivery. Further, it is used as a sealant for leaking farm ponds and a calcium and magnesium chelating agent. In addition to this, it is used in ceramics, leather tanning, flame retardants, paper pulping, paper coatings, textile processing, ore flotation, anticorrosion pigments and rubber production.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
