Hydrogenated Prunus Domestica Seed Oil

Hydrogenated Prunus Domestica Seed Oil is a processed form of plum seed oil that has undergone hydrogenation—a process that adds hydrogen to make the oil more stable and solid at room temperature. This transformation extends shelf life and improves texture in formulations, whilst retaining the conditioning properties of the original plant oil.In skincare, it functions as an occlusive emollient, meaning it sits on the skin surface to reduce moisture loss and create a protective layer. It's derived from a natural source but is chemically modified for cosmetic stability and performance.

Hydrogenated Prunus Domestica Seed Oil works by forming an occlusive film on the stratum corneum (the outermost skin layer). This reduces water evaporation from the skin, helping to maintain hydration levels. The fatty acid profile of plum seed oil also allows it to integrate into the skin's natural lipid matrix, supporting barrier function without a heavy or greasy residue.The hydrogenation process makes the oil more stable than its unmodified counterpart, meaning it remains effective throughout the product's shelf life and resists breaking down when exposed to air or light.

This ingredient is typically found in creams, balms, and moisturisers rather than serums or lightweight products. It works well layered over hydrating ingredients to seal them in, particularly on dry patches. If your skin is prone to congestion, use sparingly on the T-zone and focus application on naturally drier areas like cheeks and neck.

Generally well-tolerated and considered safe for cosmetic use. Those with specific allergies to stone fruit plants should exercise caution, though this is rare.
