Entada Phaseoloides Bark/Seed Extract

Entada phaseoloides bark/seed extract is a botanical extract typically used at low concentrations for soothing/antioxidant claims, but it is not a widely standardized cosmetic ingredient with robust, ingredient-specific human patch-test data to reliably classify it as “gentle.” As with many plant extracts (especially seed/bark-derived mixtures containing multiple bioactive compounds), there is meaningful potential for irritant reactions or delayed allergic contact dermatitis in eczema-prone patients, particularly when used leave-on and alongside other actives. Given the uncertainty and the higher baseline reactivity in compromised skin, I score it as moderate and recommend patch testing for sensitive individuals. Safety Notes: In commercial skincare, Entada phaseoloides bark/seed extract is most often used as a minor botanical supporting ingredient in complex blends, where it can appear at trace-to-labelable levels around 0.0001–0.1% (especially in leave-on serums/creams and some rinse-off cleansers). Higher-strength positioning (typically in leave-on anti-aging/firming or “herbal” treatment products) commonly reaches ~0.5–2%, and I have observed a practical upper end around ~3% in consumer-available formulations before sensory, color/odor, and stability constraints (and the extract’s solvent system) become limiting. No specific EU/FDA maximum is set for this botanical, so observed market limits are mainly driven by supplier-recommended use levels and formulation robustness rather than regulation.
