Zinc Gluconate

What is Zinc Gluconate?

Zinc gluconate is the zinc salt of gluconic acid, an organic compound derived from the fermentation and oxidation of glucose. This water-soluble chelate appears as a white powder and is widely used in personal care products like deodorants, facial cleansers, and moisturizers. In formulations, it releases zinc ions gradually, providing antimicrobial effects that target bacteria responsible for product spoilage or odor. As a biocide, it helps maintain product stability by inhibiting microbial growth. Its skin conditioning properties support the skin's natural barrier, promoting hydration retention and suppleness. The deodorant function works by neutralizing odor compounds and reducing bacterial activity on the skin surface, all without impacting perspiration. Valued for its stability and mild profile, it integrates well into rinse-off and leave-on products at typical low levels.
