Potassium Gluconate
What is Potassium Gluconate?
Potassium gluconate is the potassium salt of gluconic acid, a naturally derived organic acid formed by oxidizing glucose through microbial fermentation processes. This water-soluble compound falls into the multifunctional additives category in cosmetics. It works mainly as a chelating agent, forming complexes with trace metal ions like calcium, magnesium, and iron found in water or ingredients. By sequestering these ions, it prevents catalytic reactions that lead to oxidation, rancidity, or color changes in products. It also functions as a buffering agent to help maintain stable pH levels for gentle application. In formulations such as cleansers, serums, and lotions, it supports overall product integrity. Additionally, its skin-protecting role involves creating a barrier that shields against external irritants, promoting a smoother feel during use.
