Flavanols are a subgroup of flavonoids, a class of polyphenolic compounds found in various plants. They are known for their antioxidant properties and are commonly present in fruits, vegetables, and tea. In skincare and cosmetic formulations, flavanols are valued for their ability to protect the skin from oxidative stress and support overall skin health.

Chemical Composition and Structure:
Flavanols are characterized by their structure which includes:

• Basic Structure: A three-ring structure with hydroxyl groups, typically consisting of two benzene rings (A and B rings) and a heterocyclic ring (C ring).
• Substituents: Flavanols often contain hydroxyl groups attached to the benzene rings and may also include other substituents that influence their antioxidant properties.

Common flavanols include:

• Epicatechin
• Catechin
• Theaflavins (found in tea)

Physical Properties:

• Appearance: Generally exists as a powder or crystalline substance.
• Solubility: Poorly soluble in water but soluble in organic solvents.
• Odor: Typically has a neutral odor or slight characteristic scent depending on the source.

Production Process:

1. Extraction: Flavanols are extracted from plant sources such as cocoa beans, apples, or tea leaves using solvents or water.
2. Purification: Extracts are purified to isolate flavanols, often through filtration and chromatography.
3. Formulation: The purified flavanols are incorporated into cosmetic products in various concentrations.

Applications:

• Cosmetics: Used in anti-aging creams, serums, and lotions for their antioxidant properties, which help protect the skin from environmental damage and reduce signs of aging.
• Personal Care: Included in products aimed at improving skin elasticity and overall health.

Environmental and Safety Considerations:

• Environmental Impact: The production involves the extraction of natural plant sources. Sustainable sourcing practices are recommended to minimize environmental impact.
