Rubus Occidentalis Fruit Extract

Rubus occidentalis (black raspberry) fruit extract is typically used at low concentrations as an antioxidant/soothing botanical, and it is not a recognized primary irritant in standard cosmetic patch-test datasets. However, as a complex plant extract containing polyphenols and trace natural aroma constituents, it carries a small but real risk of irritation or allergy in highly reactive or eczematous skin, especially in leave-on products. Given the sensitive-skin population and the unpredictability of botanical variability, it is best classified as generally well-tolerated but not inert. Safety Notes: In commercial skincare, Rubus Occidentalis (black raspberry) fruit extract is most often used as a minor antioxidant/marketing botanical in complex blends, where it commonly appears at very low levels (around 0.0005–0.05%) especially in leave-on serums, creams, and sunscreens. Higher-strength consumer products (typically leave-on “antioxidant” or “brightening” serums/ampoules and some mask concentrates) can reach ~1–5% when the extract is a primary featured botanical and supplied as a dry extract or high-solids concentrate. Rinse-off cleansers and wash-off masks usually sit toward the lower-to-mid end due to cost and limited contact time, while no specific FDA/EU maximum applies beyond general cosmetic safety and supplier use-level guidance.
