Zinc Glycinate
What is Zinc Glycinate?
Zinc glycinate is a chelated form of zinc, where zinc ions are bound to glycine, a simple amino acid, creating a stable, water-soluble complex. This synthetic ingredient belongs to the category of metal-amino acid salts commonly incorporated into cosmetic products like cleansers, toners, serums, and moisturizers. Its primary function involves pH regulation: as a buffering agent, it resists changes in acidity to keep formulations within a stable range, preventing degradation of active components. As a pH adjuster, it precisely modifies the product's acidity to align with skin compatibility, enhancing ingredient solubility, preservative effectiveness, and overall formula integrity. This mild zinc source is preferred in modern skincare for its gentle profile and ability to contribute to balanced, non-disruptive products without promoting pore clogging.
