Overview

E452I - Sodium polyphosphate

Sodium polyphosphate (E452i) is a group of long-chain sodium phosphate salts used to keep foods stable, moist, and smooth. You may also see it called sodium hexametaphosphate. It helps bind water, control minerals, and support texture in processed foods.

E452IV - Calcium polyphosphate

Calcium polyphosphate (E452iv) is a family of calcium salts made from chains of phosphate units. Food makers use it to hold moisture, help oil and water mix, and keep texture steady in many processed foods. It also goes by calcium metaphosphate.

Popular questions

Is sodium hexametaphosphate safe for dogs?
Generally yes—it's commonly used in dog foods and dental chews to help reduce tartar and is considered safe at approved levels; dogs with kidney disease or on phosphorus-restricted diets should avoid excess phosphates and you should consult your vet.
Is sodium hexametaphosphate safe?
Yes—it's permitted as a food additive (EU E452i) and considered safe at typical use levels; EFSA set a group ADI for phosphates of 40 mg/kg body weight per day expressed as phosphorus.
Is sodium hexametaphosphate bad for you?
Not at normal food levels; however, very high phosphate intake can disrupt mineral balance and is a concern for people with kidney disease.
Is sodium hexametaphosphate safe in food?
Yes—it's an approved emulsifier/sequestrant (E452i) and is safe within permitted levels; authorities limit total phosphate intake (e.g., EFSA ADI 40 mg/kg bw/day as phosphorus).
What is sodium hexametaphosphate used for?
In foods it functions as a sequestrant, emulsifier, stabiliser, humectant and thickener—binding metal ions, stabilising proteins/emulsions, and retaining moisture in products like processed meats/seafood, cheeses/dairy, beverages, and baked goods.
