DIPTERYX ODORATA SEED EXTRACT.

Valuable CAS 90028-06-1 / FRAGRANCE

Dipteryx Odorata Seed Extract, derived from the Tonka bean, is a multi-functional ingredient recognized for its brightening, hydrating, and protective properties. It enhances skin radiance by converting UV light into visible light, while also supporting collagen production and offering antioxidant and antimicrobial benefits. Its naturally high lipid content contributes to its oil-soluble nature, making it a valuable addition to nourishing formulations.

Antioxidant Brightening Hydrating Collagen Booster Antimicrobial Masking Perfuming

Science

Mechanism of Action

This extract functions as an optical brightener by absorbing harmful ultraviolet radiation and subsequently re-emitting it as beneficial visible light, which contributes to an illuminated and more even-toned complexion. It provides robust antioxidant protection, effectively neutralizing free radicals and mitigating oxidative stress. Furthermore, it significantly enhances skin moisturization and stimulates collagen production to improve dermal density. The extract's inherent antibacterial properties may also assist in reducing redness and inflammation, making it beneficial for problematic skin conditions.

Key findings

  1. 01 An in vivo study on a biofermented derivative of Dipteryx Odorata Seed (Tonka Bean) demonstrated a 35% increase in skin moisture levels over a 24-hour period.
  2. 02 Further in vivo research on Tonka Bean Bioferment indicated a significant increase in skin moisturization by 52.7% after four weeks of application, compared to an untreated control.
  3. 03 After four weeks of consistent use, Tonka Bean Bioferment also led to an average improvement of 11.3% in skin collagen density.
  4. 04 In vitro studies revealed that Tonka Bean Seed Extract (TBSE) exhibited antimicrobial activity against bacteria such as E. coli and P. aeruginosa at concentrations around 15.6 mg/mL. However, the study noted that a lack of standardized concentration makes reproducibility and comparison across studies challenging.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) has not explicitly reviewed DIPTERYX ODORATA SEED EXTRACT. While Tonka beans naturally contain coumarin (1-4%), which has led to ingestion restrictions in food products due to potential hepatotoxicity and haematotoxicity at large doses, its topical cosmetic use is generally permitted, often as a fragrance ingredient. The risk associated with typical cosmetic application concentrations is considered low. Products containing this ingredient are frequently manufactured in FDA-registered facilities. SkinSAFE classifies it as 'Irritant Free', and the Environmental Working Group (EWG) rates it 'LOW' for concerns like allergies and immunotoxicity.
