Factory Supply GDL 99% Gluconolactone Powder
Gluconolactone: What is it?
Gluconolactone, abbreviated as GDL, is a multifunctional compound obtained by the oxidation of glucose. It appears as white crystals or powder and is readily soluble in water. Gluconolactone is an internationally recognized safe raw material, widely used in the food, cosmetics, and pharmaceutical industries. It can be used as an acidulant, protein coagulant, preservative (for fish and meat products), and leavening agent. In cosmetics, it possesses moisturizing, antibacterial, and antioxidant properties, with low irritation, making it suitable for various skin types, including sensitive skin. Furthermore, it has applications in other industries such as pharmaceuticals and textiles, making it a versatile and relatively safe compound.

Gluconolactone: Main Skin Care Functions
1. Keratin Renewal
Gluconolactone gently exfoliates dead skin cells, improving rough skin texture, enlarged pores, and uneven skin tone, leaving skin smoother and brighter without causing irritation or barrier damage.
2. Moisturizing
Gluconolactone, with its molecular structure and hydrophilic properties, forms a moisturizing film on the skin surface, effectively reducing moisture loss, especially suitable for dry or sensitive skin.
3. Acne-Fighting Aid
Studies show that skincare products containing gluconolactone can effectively reduce inflammatory acne, with effects comparable to some traditional acne-fighting ingredients, but with lower irritation. Its gentle antibacterial and anti-inflammatory properties help soothe acne-prone skin and improve redness and discomfort.
4. Antioxidant
Gluconolactone possesses antioxidant capabilities, helping to protect the skin from oxidative stress by chelating metal ions and reducing free radical generation. Experiments have shown that it can also partially absorb ultraviolet rays, reduce UVB-induced damage, and combat photoaging-related elastin denaturation, thereby helping to prevent premature skin aging.
5. Strengthening the Skin Barrier
Gluconolactone helps strengthen the skin barrier function and enhance resistance to external stimuli by gently conditioning the stratum corneum, maintaining hydration, and providing antioxidant protection.
Gluconolactone: Multiple Applications
Food Additives
Gluconolactone is a multifunctional additive in the food industry. It is widely used as a protein coagulant in the production of soy and dairy products, imparting a delicate texture and good water retention. In meat processing, gluconolactone improves quality by enhancing water retention and improving taste, and helps reduce the amount of nitrite used. It is also used as a preservative in meat and seafood products, effectively extending shelf life and helping to maintain the color and elasticity of ingredients. Gluconolactone can also be used as an acidulant in beverages and jellies to adjust flavor, or as a leavening agent in pastry making.
Cosmetics
As a new generation of polyhydroxy acid, gluconolactone is widely used in skin care products (such as facial cleansers and masks). It gently promotes keratin metabolism, and has moisturizing, antioxidant, and skin barrier repair functions. It is suitable for sensitive skin. Studies show that it is effective in helping to improve mild to moderate acne, and also has anti-inflammatory and soothing effects.
Other Applications
In the pharmaceutical and cosmetic industries, gluconolactone can be used in toothpaste formulations to help clean tartar, or as an intermediate in the synthesis of certain drugs. Industrially, it can be used as a chelating agent to prevent the formation of milkstone and tartar, and is also used for the flocculation treatment of protein-containing wastewater.
