Potassium Tripolyphosphate (KTPP)
Product Overview:
Identification of Substance: pentapotassium triphosphate
CAS #: 13845-36-8
Potassium tripolyphosphate (KTPP) is a versatile phosphate compound used across food processing, water treatment, and detergent manufacturing applications. It is commonly employed in food processing for moisture retention in meat and seafood products, improving texture and reducing drip loss during storage and cooking. Additionally, it serves as a sequestering agent in industrial water treatment, binding metal ions to prevent scale and discoloration in process water. KTPP is also utilized in specialty detergent formulations as a builder that improves cleaning performance in hard water. Furthermore, it finds applications in ceramics manufacturing as a dispersant for clay slurries.
