Purified Water

Purified Water is water that has undergone treatment processes such as distillation, deionization, reverse osmosis, or filtration to remove impurities, minerals, and microorganisms to meet pharmacopeial standards. It serves as the universal solvent in cosmetic formulations, typically comprising 60-85% of most emulsions and aqueous products. Formulators choose purified water over tap water because its consistent quality and lack of minerals prevents interference with active ingredients, ensures product stability, and eliminates variables that could affect color, odor, or preservation.
