Prunus Domestica Seed Oil

Prunus domestica (plum) seed oil is an emollient lipid typically used at a few percent up to ~100% in facial oils, and as a refined triglyceride-rich oil it is generally well-tolerated and supports barrier function. However, like other botanical seed oils it can contain trace aromatic components and is susceptible to oxidation, which can increase stinging/irritation risk in highly reactive or eczematous skin. Clinically, it fits a “gentle” profile for most users, but not completely inert for severely sensitized populations. Safety Notes: In commercial cosmetics, Prunus domestica (plum) seed oil is often used at trace-to-low levels (~0.05–0.5%) as a label-claim emollient component within broader oil blends in creams, lotions, and hair products (leave-on) or as a minor refatting oil in rinse-off cleansers. At the high end, it is widely sold directly to consumers as a 100% neat facial/body oil and is also used at very high levels (typically ~50–99%) in anhydrous oil serums, balms, and lip oils where it serves as the primary emollient. No specific EU/FDA concentration cap is generally applied to this fixed vegetable oil beyond standard cosmetic safety and impurity/allergen considerations.
