Essentially Natural Deionised Water is ultra-low-mineral water produced via ion exchange to remove dissolved ions and salts. It is commonly used as the water phase in cosmetics like creams, lotions, gels, and toners because it helps formulas behave more predictably. Deionised water is also useful for equipment and devices where mineral deposits are a problem. It is not sterile and is intended for cosmetic, household, and technical use rather than drinking.

Q: Does deionised water expire?
A: It does not expire like food, but purity can decline after opening due to exposure to air and contamination.

interfere with formulas.
Q: Should I preserve products made with deionised water?
