Ingredient review
Hydrogenated Plum Seed Oil Esters
INCI: Prunus Domestica/Hydrogenated Prunus Domestica Seed Oil Esters
A gentle, plant-derived emollient that hydrates and smooths skin without clogging pores, ideal for sensitive and dry skin types.
In plain English
This ingredient is a modified version of plum seed oil. The oil is hydrogenated, which means it's turned into a more stable, semi-solid butter-like texture. It sits on the skin's surface to lock in moisture and make skin feel soft and smooth, without feeling greasy. Think of it as a lightweight, non-clogging moisturizer that also helps other ingredients spread nicely.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Hydrogenated plum seed oil esters are created by taking oil from plum seeds (Prunus domestica) and partially hydrogenating it to form esters—compounds that are more stable and have a richer, butter-like consistency. This process makes the ingredient more shelf-stable and easier to formulate into creams and balms.
How it works
When applied to the skin, this ingredient forms a thin, breathable film that reduces water loss (transepidermal water loss, or TEWL—the amount of moisture that evaporates from your skin). It also fills in rough patches on the skin's surface, making it feel smoother. Its ester structure allows it to blend well with both oil and water phases in a formula, improving the texture and feel of the product.
Pros
Non-greasy hydration
Provides lasting moisture without leaving a heavy, oily residue, making it comfortable for daily use on the face and body.
Pore-friendly
Has a low comedogenic rating, meaning it is unlikely to clog pores, which is great for acne-prone or oily skin types.
Cons and cautions
Limited standalone efficacy
For very dry or compromised skin, this ingredient works best when combined with other humectants (like glycerin) and occlusives (like petrolatum) for deeper hydration.
Potential allergen
Although rare, individuals with a known allergy to plums or related stone fruits may experience a reaction; patch testing is recommended.
Best for
- People with dry or dehydrated skin
- Those who prefer non-greasy, lightweight moisturizers
Use caution if
- Individuals with known allergies to plums or stone fruits (rare)
Usage tips
Safety summary
Considered safe for cosmetic use with low irritation and comedogenic potential. Rare allergic reactions possible in individuals with stone fruit allergies. Always patch test new products.
Research notes
While plum seed oil itself has some research supporting its moisturizing and antioxidant properties, specific studies on hydrogenated plum seed oil esters are limited. Its safety profile is supported by analogy to other hydrogenated plant oils and esters used in cosmetics.
