Deionized Water
Deionized water is water that has had almost all of its mineral ions removed, such as sodium, calcium, iron, and copper. In cosmetics, it serves as a primary solvent for other ingredients, ensuring product stability and preventing unwanted reactions that minerals in tap water might cause. It forms the base for most water-based formulations.
