Product Introduction
Gluconic Acid is a non-corrosive, mild organic acid produced through the oxidation of glucose. As a multifunctional compound with excellent chelating properties, it typically appears as a clear, pale yellow to colorless aqueous solution (50% concentration) in commercial applications. This versatile acid occurs naturally in honey, fruit juices, and wine, and is valued for its ability to form stable complexes with di- and trivalent metal ions while maintaining low toxicity and high biodegradability. Its unique combination of acidity and sequestering power makes it ideal for applications requiring controlled pH adjustment without metal corrosion.
