Dipotassium Glycyrrhizinate Oral Health Agent: Inhibits Porphyromonas gingivalis Biofilm Formation in Gingival Models

Introduction to Dipotassium Glycyrrhizinate

Dipotassium Glycyrrhizinate is an active ingredient extracted from the roots of the Glycyrrhiza plant (licorice). Its chemical name is 18β-Glycyrrhizic Acid Dipotassium Salt, belonging to the triterpenoid saponin class of compounds. With a molecular formula of C₄₂H₆₀K₂O₁₆, it appears as a white or off-white crystalline powder, featuring a sweet taste, excellent water solubility, and stable chemical properties.

Major Applications

1. Pharmaceutical Field

• Anti-inflammatory and Anti-allergic Effects: By inhibiting the release of inflammatory factors and histamine secretion, it alleviates symptoms such as skin inflammation, eczema, and atopic dermatitis, offering corticosteroid-like effects without associated side effects.
• Hepatoprotective and Detoxifying Actions: Reduces transaminase activity in the liver, mitigating damage to hepatocytes caused by drugs or toxins, and is used in treating chronic hepatitis and cholestatic jaundice.
• Immunomodulatory Properties: Enhances the body’s immunity by promoting the production of cytokines such as interleukin-2.

2. Cosmetic Field

• Soothing and Anti-sensitivity: Suppresses inflammatory responses, reducing skin redness, swelling, and itching, making it suitable for sensitive skin care.
• Whitening and Moisturizing: Inhibits tyrosinase activity to reduce melanin production while providing hydration and moisture-locking capabilities, improving uneven skin tone.
• Repair and Regeneration: Promotes wound healing by accelerating granulation tissue formation and fibroblast proliferation.
• Synergistic Enhancement: When combined with ingredients like tranexamic acid, pro-xylane, and vitamin C, it enhances the efficacy of whitening, anti-wrinkle, and antioxidant effects.

3. Food Field

• Natural Sweetener: Approximately 150 times sweeter than sucrose, it is used in candies, beverages, and preserved fruits to improve taste and confer health benefits.
• Functional Additive: Acts as an antioxidant and flavor enhancer, improving overall food quality.

Advantages

• High Safety: Recognized as a GRAS (Generally Recognized as Safe) substance by the US FDA and deemed safe and non-toxic by the EU CIR Expert Panel.
• Strong Compatibility: Synergizes with various active ingredients to enhance product efficacy.
• Broad Applications: Widely used in pharmaceuticals, cosmetics, and food industries to meet diverse needs.

Dipotassium Glycyrrhizinate stands out as a crucial active ingredient across multiple fields due to its anti-inflammatory, anti-allergic, whitening, moisturizing, and regenerative properties, particularly suited for sensitive skin care and functional food development.
