Description

Gluconic Acid CAS NO 526-95-4 is a non-corrosive, non-volatile organic acid derived from the oxidation of glucose, valued for its excellent chelating and mild acidic properties. It is a versatile chemical intermediate and additive prized for its biodegradability and safety profile in sensitive applications. This product is essential for manufacturers in the food & beverage, pharmaceutical, construction, and cleaning industries seeking a safe, effective, and multifunctional ingredient.

Application

• Food & Beverage Additive: Used as an acidity regulator, leavening agent, and sequestrant in beverages, baked goods, and dairy products to control tartness and prevent mineral scaling.
• Pharmaceutical & Nutraceutical: Serves as an excipient in formulations, a component in mineral supplements for improved bioavailability, and in dental care products for descaling.
• Industrial Cleaning & Derusting: A key component in alkaline and acidic cleaners, degreasers, and derusting solutions due to its ability to chelate calcium, magnesium, and iron ions without corroding surfaces.
• Construction & Concrete: Acts as a set retarder and water reducer in concrete admixtures, improving workability and final strength by complexing calcium ions.
• Personal Care & Cosmetics: Functions as a pH adjuster, chelating agent, and skin conditioning agent in creams, lotions, and hair care products.
• Agriculture: Used in micronutrient fertilizers and foliar sprays to enhance plant uptake of minerals like iron, zinc, and manganese.
• Textile & Leather Processing: Employed in dyeing and tanning processes as a pH control agent and sequestrant to improve color fastness and product quality.
• Water Treatment: Effective in controlling scale formation in boilers and cooling towers by chelating hardness-causing ions.
