Lactobionic Acid CAS#96-82-2

Outstanding Dissolving Performance:Lactobionic acid boasts favorable water solubility with a solubility parameter of 10 grams per 100 milliliters of water, which renders it highly suitable for being incorporated into diverse formulas within the food, pharmaceutical and cosmetic sectors.
Health Care Functions:Thanks to its potent chelating ability and moisturizing effects, this ingredient is widely adopted in wellness items. It effectively locks moisture into the skin and facilitates better absorption and transportation of functional active components.
Compatible Carrier for Medicinal Administration:In the research and creation of targeted medication carriers that feature excellent biological compatibility, lactobionic acid serves as an indispensable component, helping medicines achieve stronger therapeutic effects.
Mild Flavor & High Safety Level:When applied as a food additive, lactobionic acid features a mild agreeable flavor and reliable safety attributes. It elevates the taste experience of finished products while bringing no adverse toxic impacts to the human body.

Lactobionic acid, with CAS number 96-82-2 and molecular formula C₁₂H₂₂O₁₂, appears as white or faint off-white fine crystalline powder that is odorless, slightly sour-tasting and notably hygroscopic. In terms of physicochemical properties, it dissolves readily in water with a solubility of 10 grams per 100 milliliters under ambient temperature while hardly dissolving in ethanol, acetone and other organic solvents; its molecular structure contains abundant hydroxyl groups and a carboxyl group, endowing it with powerful metal chelating capacity to restrain formula oxidation and discoloration, as well as prominent moisturizing ability to lock surface moisture effectively. As a third-generation polyhydroxy acid, it features mild acidity far less irritating than traditional alpha-hydroxy acids such as glycolic acid, capable of gently exfoliating aged keratin and regulating pH value, and it boasts favorable stability under sealed and dry storage conditions along with outstanding biocompatibility that allows easy metabolism in human bodies without toxic accumulation.

Widely applied across multiple sectors, it is a prevalent ingredient in cosmetics and personal care items including essences, facial masks and toothpaste for brightening skin tone, diminishing fine lines, sustaining hydration and extending product shelf life via chelation; in the pharmaceutical field, it acts as a core material for liver-targeted drug delivery systems, a multifunctional excipient for injections, ointments and syrups, and a key component in organ preservation liquids to alleviate oxidative injury to isolated organs; approved by the FDA and EU food authorities as a safe food additive, it serves as an acidity regulator, flavor modifier and antioxidant in beverages, baked goods and canned food to prevent lipid rancidity and lengthen shelf life with a mild palatable sour flavor; additionally, it is utilized in fine chemicals, semiconductor precision cleaning and biological culture medium preparation for removing micro metal impurities and supporting biochemical research.
