Potassium Acetate Anhydrous Side Effects

Potassium Acetate E261 is a white crystalline powder with a salty taste. It is used as a preservative, acidity regulator, buffer, corrective, and color protector. Though it’s considered safe, some are convinced it has potentially dangerous health effects.

What Is Potassium Acetate E261?

Potassium acetate E261 (KCH3COO) is the potassium salt of acetic acid. Potassium acetate is used as a food additive as a preservative and acidity regulator.

Possible Side Effects of Potassium Acetate E261

Though Potassium Acetate E261is regarded as safe supplement, there maybe some side effects:

  • symptoms of potassium intoxication which are tingling or burning sensation in hands and feet
  • weakness
  • lack of muscle tone
  • listlessness
  • mental confusion
  • weakness and heaviness of the legs
  • low blood pressure
  • diarrhea, or
  • heart irregularities
