Popular questions
  1. Monosodium citrate crystals are see in which disease?

    None—monosodium citrate is not known to form diagnostic crystals in disease; you may be thinking of monosodium urate crystals, which are seen in gout.

  2. Where does monosodium citrate come from?

    It’s made by neutralizing citric acid (usually produced by microbial fermentation with Aspergillus niger on sugar) with a sodium base; citric acid also occurs naturally in citrus fruits.

  3. Why is monosodium citrate flammable when it is a ionic compound?

    It isn’t generally classified as flammable, but like many organic salts it can decompose and burn if strongly heated or involved in a fire; fine organic powders can also be combustible under certain conditions.

  4. Why monosodium citrate is flammable?

    It’s typically not considered flammable; any burning occurs only when heated strongly, as the organic component decomposes and can fuel combustion.

  1. 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.

  2. 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.

  3. 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.

  4. 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).

  5. 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.
