What are the preservatives used in Hydralyte?

|

Hydralyte Oral Electrolyte Powder and Hydralyte Effervescent Electrolyte Tablets DO NOT contain any preservatives.

Hydralyte Oral Electrolyte Solutions contain small amounts of potassium sorbate and sodium benzoate to prevent product spoilage. Both of these ingredients are found naturally in fruits such as oranges, lemons and cranberries, and help protect the fruit from mould.
