Zinc Acetate

What is Zinc Acetate?

Zinc acetate is an inorganic zinc salt derived from acetic acid, existing as a white, crystalline powder soluble in water. In cosmetics, it primarily functions within astringent and antimicrobial product categories, such as toners, lotions, and deodorants. It operates by delivering zinc ions that interfere with microbial enzymes and cell processes, thereby limiting bacterial proliferation. Simultaneously, its astringent action involves precipitating surface proteins on the skin, yielding a contracted, toned appearance. This compound supports formulation stability and provides a barrier-like effect against environmental stressors. Typically incorporated at low levels, it remains on the skin's exterior without significant absorption, contributing to refined texture and controlled shine in targeted applications.
