Prunus Domestica/Hydrogenated Prunus Domestica Seed Oil Esters

Prunus domestica seed oil esters are derived from plum kernel oil and then hydrogenated — a process that stabilises the oil and makes it less prone to oxidation. The result is a lightweight conditioning agent commonly used in skincare formulations.In products, this ingredient functions primarily as an emollient and skin conditioner, helping to soften the outer layers of skin and support the skin barrier. It's often chosen for its stability and non-greasy feel compared to raw plant oils.

Hydrogenated plum seed oil esters work by sitting on the skin surface and in the upper stratum corneum, where they reduce transepidermal water loss (TEWL). This occlusive action traps existing moisture, helping the skin feel more hydrated and conditioned.The hydrogenation process gives this ingredient better oxidative stability than raw oils, meaning it's less likely to degrade or become rancid in formulations — a practical benefit for shelf life and performance.

This ingredient is typically found in moisturisers, serums, and creams where it blends with other conditioners and humectants. It works well in any routine step requiring hydration support. No special application technique is needed — apply to clean skin as part of your regular moisturising layer.

Generally well-tolerated across most skin types. Hydrogenation makes it stable and low-risk for irritation. Those with tree nut sensitivities may wish to check product labels, though cosmetic use is unlikely to pose systemic risk.
