Honokiol: Lipophilic Magnolia Bark Active for Skin Defense, Soothing, and Complex Care Formulations

Molecular Identity

• INCI Name: Honokiol
• Molecular Formula: C₁₈H₁₈O₂
• Source: Isolated from the bark of Magnolia officinalis and Magnolia grandiflora

Functional Profile and Application Focus

Honokiol is a biphenolic compound from magnolia bark, valued for its use in cosmetic formulations that target sensitive skin states, oxidative stress, and urban environmental exposure. Its lipophilic structure makes it suitable for oil-phase delivery systems or encapsulated actives.

• Oxidative Protection: Helps defend against free radical accumulation in the lipid matrix
• Calming Mechanism: Appropriate for post-treatment care or barrier-sensitive products
• Botanical Origin: Magnolia-derived, fitting natural performance-based product lines
• Ideal for Complex Systems: Use in night balms, recovery serums, or skin stress protection lines

Honokiol is commonly formulated into intensive creams, serum-in-oil emulsions, dermo-cosmetic balms, and skin repair boosters. Bulk availability ensures stable supply for industrial-scale projects and product lines.

• Recovery-focused care: 0.05–0.2%
• Night formulations or lipid boosters: 0.1–0.3%
• Urban defense or antioxidant complexes: 0.05–0.15%
