Litsea Cubeba Fruit Extract

Litsea cubeba fruit extract is primarily used for fragrance/antimicrobial effects and is typically rich in citral and other terpenes that are well-documented irritants and potential sensitizers in patch testing. Even at low leave-on concentrations, these constituents can trigger stinging, erythema, or eczema flares in reactive skin, with higher risk when combined with other fragranced products. Given its fragrance-like allergen profile and the disproportionate risk in eczema patients, it warrants a significant irritancy score. Safety Notes: In commercial products, Litsea cubeba fruit extract is most often used as a minor botanical/antioxidant component or part of a standardized blend, with effective use levels commonly landing in the 0.01–0.5% range; at the very low end (~0.0001–0.005%) it appears as a trace component carried within multi-extract complexes or preservative/fragrance-associated blends. Higher-strength consumer-available formulations (especially rinse-off cleansers, scalp products, or “botanical concentrate” leave-on serums) can reach ~1–2% total extract, with levels above this being uncommon due to odor, sensitization potential from associated volatile constituents, and general stability/compatibility constraints in leave-on products.
