In recent years, water-soluble ingredients have grown increasingly important in cosmetic formulations, serving as a fundamental basis for ensuring efficacy and stability. With hydrophilic properties, they are widely used in various skincare and hair care products, covering solvents, astringents, preservatives, humectants and other categories. They play irreplaceable roles in dissolving components, locking moisture, and improving skin feel.

As the most widely used core material in cosmetics, water purity directly determines product quality. Purified water effectively removes metal ions, microorganisms and organic impurities, preventing oxidation, discoloration and precipitation, thus ensuring formula stability and safety. Meanwhile, innovative functional waters such as alkaline ionized water, deep ocean water and mineral ion water have enriched product differentiation. The industry stresses strict control over water purity in production, proper use of metal ion sequestering agents, and strict limits on salts and impurities to improve quality at the source. Technological upgrades and standardized application of water-soluble ingredients are driving the beauty industry toward safer, more efficient and stable development.
