What is Calcium Gluconate?

Calcium gluconate is a water-soluble calcium salt of gluconic acid, formed by oxidizing glucose from natural sources like corn or fruits. In cosmetics, it serves in moisturizers, serums, lotions, and oral care products. As a humectant, it binds water molecules to the skin's surface layers, promoting sustained moisture retention and plumpness. Its skin conditioning properties help preserve the skin's natural barrier, enhancing smoothness and elasticity without greasiness. The compound's mild ionic nature also stabilizes formulations and provides a subtle buffering effect. In oral care items like toothpaste, it aids in mineral delivery to support enamel resilience. Derived through fermentation processes, it offers a biocompatible option for everyday personal care routines, blending efficacy with broad compatibility across skin types.
