Glycyrrhiza uralensis root prenylflavonoids are bioactive compounds extracted from the root of the Glycyrrhiza uralensis plant, commonly known as Chinese licorice. These flavonoid compounds are known for their antioxidant, anti-inflammatory, and anti-aging properties. Prenylflavonoids are characterized by the presence of prenyl groups in their chemical structure, which enhance their biological activity.

Chemical Composition and Structure:

Key Components:
Prenylflavonoids: Flavonoids with prenyl groups, such as liquiritin and glycyrrhizin, offering antioxidant and anti-inflammatory effects.
Glycyrrhizin: An important triterpenoid saponin present in the root, known for its soothing and anti-inflammatory properties.
Flavonoids: Antioxidant compounds that help neutralize free radicals and protect the skin from environmental damage.
Structure: Prenylflavonoids feature a flavonoid structure with prenyl groups that enhance their bioavailability and biological activity.

Physical Properties:

Appearance: Powder or liquid extract with variable color depending on concentration and purity.
Odor: May have a characteristic herbal and sweet aroma.
Consistency: The powder is fine and slightly granular, while the liquid extract may be viscous.

Production Process:

Extraction: Glycyrrhiza uralensis roots are treated with solvents to extract the prenylflavonoids.
Purification: The extract is purified to isolate specific prenylflavonoids.
Formulation: Purified prenylflavonoids are incorporated into cosmetic and personal care products.

Applications:

Skincare: Used in skin care products for their antioxidant and anti-inflammatory properties, helping to reduce inflammation and improve overall skin appearance.
Anti-Aging: Included in anti-aging formulations to combat signs of aging, thanks to their ability to neutralize free radicals and improve skin elasticity.

Safety and Environmental Considerations:

Safety: Glycyrrhiza uralensis root prenylflavonoids are generally regarded as safe for use in cosmetics and personal care products when used as directed. Individuals with sensitive skin or allergies to licorice should exercise caution.
Environmental Impact: Sustainability of root harvesting and extraction should be considered to minimize environmental impact.

INCI:


Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.
