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
It is a synthetic ester derived from palm kernel oil and ditrimethylolpropane, designed to mimic the texture of natural oils while being more stable and less greasy.
How it works
It sits on the skin's surface to fill in rough patches and reduce water loss, creating a protective film that makes skin feel soft and smooth. It also helps other ingredients spread evenly.
Pros
Lightweight feel
Unlike heavy oils, this ingredient absorbs quickly and leaves a silky finish, making it great for daytime use and under makeup.
Low pore-clogging risk
It has a low comedogenic rating, so it's less likely to cause breakouts compared to many natural oils.
Cons and cautions
Sustainability concerns
Palm kernel oil production can contribute to deforestation if not sourced responsibly. Look for RSPO-certified palm ingredients.
Limited research
There are fewer peer-reviewed studies on this specific ester compared to more common emollients, so long-term data is sparse.
Best for
- People with oily or combination skin who want lightweight moisture
- Anyone looking for a non-greasy emollient in makeup or skincare
Use caution if
- Those with a known allergy to palm-derived ingredients (rare)
