PROPERTIES: THEALOZ is a sterile, preservative free, isotonic and pH neutral aqueous ophthalmic solution. Its main ingredient is trehalose, a natural simple sugar present in many plants and animals, which can survive in extremely dry conditions. Trehalose protects and hydrates and is an antioxidant. For these reasons, it is essential in the anhydrobiotic process used in certain tiny organisms (a slow metabolism that helps them live in dry conditions). Trehalose also protects and stabilises cell membranes, by stopping change of proteins and breakdown of fats.
