Provides antioxidant protection via phenolics and iridoidsHelps minimize fine lines associated with environmental stressAnti-inflammatory properties
Fragrance
Dipteryx Odorata Bean Extract

An extract of the seeds of Dipteryx odorata (tonka bean) used as a fragrance and masking ingredient; naturally rich in coumarin, a regulated fragrance allergen.

fragranceperfumingmasking
Imparts a warm vanilla-almond-cinnamon scent profile to formulations
High coumarin content (1–3% in beans, up to 90% in absolute); coumarin is a known fragrance allergen and restricted in cosmetics by IFRA and EU regulationsMay cause skin sensitization in fragrance-allergic individuals
Other
Disiloxane

The simplest silicone fluid (hexamethyldisiloxane), a volatile carrier used to improve spreadability and deliver a dry, lightweight skin feel.
