Zinc Citrate
What is Zinc Citrate?
Zinc citrate, chemically known as trizinc dicitrate, is the zinc salt derived from citric acid, a naturally occurring organic acid found in citrus fruits. It appears as a white, odorless powder that is soluble in water. In cosmetics, it belongs to the category of antimicrobial and buffering agents. Its primary function involves releasing zinc ions that disrupt bacterial cell processes, thereby inhibiting microbial growth. This makes it valuable in formulations like cleansers, deodorants, and oral care products such as toothpastes and mouthwashes. As a biocide, it helps maintain product stability by preventing spoilage from harmful organisms. Additionally, its mild astringent nature supports surface-level cleansing without harsh effects, contributing to overall product efficacy in hygiene-focused applications.
