Comparing E452I - Sodium polyphosphate vs E452III - Sodium calcium polyphosphate

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.
