Description

D-(+)-Glucono-1,5-Lactone is a high-purity, naturally derived organic acid lactone widely used as a versatile acidulant and sequestrant. Its key value lies in its controlled, gradual hydrolysis in aqueous solutions, which provides a mild and sustained release of gluconic acid, making it ideal for applications requiring precise pH control and chelation. This product is essential for manufacturers in the food, pharmaceutical, and personal care industries seeking a safe, effective, and multifunctional ingredient.

Application

• Food Industry: Used as a slow-acting acidulant, leavening agent, and pH regulator in baked goods, dairy products (e.g., tofu), beverages, and meat processing to improve texture and shelf-life.
• Pharmaceuticals: Serves as an excipient in effervescent tablets and powders due to its non-hygroscopic nature and controlled acid release, and as a chelating agent in formulations.
• Personal Care & Cosmetics: Functions as a pH adjuster and mild exfoliating agent in skincare formulations, contributing to product stability and skin compatibility.
• Industrial Cleaning: Acts as a key component in descaling and metal cleaning solutions, where its chelating power safely removes calcium and other mineral deposits without corrosion.
• Agriculture & Animal Feed: Employed as an acidifier in animal feed to promote gut health and as a component in certain agrochemical formulations.
