What is D-(+)-Glucono-1,5-lactone (GDL)?

D-(+)-Glucono-1,5-lactone (GDL) is a naturally occurring, water-soluble lactone derived from D-gluconic acid. With a mild, slightly sweet taste, it is commonly used in the food, cosmetic, and pharmaceutical industries as a slow-releasing acidifier, coagulant, and chelating agent. Upon hydrolysis in water, GDL gradually converts into gluconic acid, lowering pH in a controlled manner—making it ideal for applications that require slow acidification.

Applications of D-(+)-Glucono-1,5-lactone (CAS 90-80-2)

1. Food Industry (E575)

• Tofu coagulant: Commonly used in Asian food products to gently coagulate soy proteins.

• pH regulator and preservative: Helps preserve taste and shelf-life in baked goods, cured meats, cheeses, and beverages.

• Acidifier: Used in dairy and plant-based products to impart mild acidity.

• Leavening agent: Used in combination with baking soda for controlled gas release.

2. Cosmetic Industry

• Functions as a chelating agent, skin conditioning agent, and pH adjuster.

• Included in skincare formulas for anti-aging and exfoliation benefits due to its PHA (polyhydroxy acid) properties, which are gentler than AHAs.

3. Pharmaceutical Applications

• Acts as a tablet binder, stabilizer, and pH control agent in oral and topical formulations.

4. Industrial and Technical Use

• Utilized in electroplating, cleaning formulations, and metal chelation processes.

• Used in cement and concrete admixtures to improve setting time and durability.
