Ptychopetalum Olacoides Bark/Stem Extract

Ptychopetalum olacoides (muira puama) bark/stem extract is a botanical extract typically used at low concentrations for conditioning/“energizing” claims, but it contains multiple bioactive phytochemicals (e.g., terpenoids/phenolics) that can act as irritants or sensitizers in reactive skin. Robust, standardized human irritation/sensitization data are limited, and variability between extract preparations increases unpredictability, especially for eczema-prone patients. Given the uncertainty and the higher risk profile of complex botanicals compared with inert humectants, a moderate irritancy score is warranted and patch testing is advisable. Safety Notes: In commercial cosmetics, Ptychopetalum olacoides (Muira Puama) bark/stem extract is most often used as a minor botanical component in multi-extract blends for anti-aging/firming or scalp/hair-tonic positioning, where finished-product levels can be as low as ~0.0005–0.05% (especially when supplied in diluted glycerin/propylene glycol carrier systems). Higher-end consumer leave-on serums, eye products, and scalp tonics occasionally use it as a featured extract at ~0.5–2.0% finished-product level, with 2% representing the upper end observed for OTC products due to cost, odor/color, and sensitization/stability constraints. This ingredient is predominantly seen in leave-on formats; rinse-off products typically sit at the low end because deposition and marketing driver levels are lower.
