Trioleyl Citrate
INCI: Trioleyl Citrate
Trioleyl Citrate is a gentle, non-greasy emollient that helps soften skin and improve the feel of your skincare products.
In plain English
Trioleyl Citrate is an ingredient made from citric acid and oleyl alcohol (a fatty alcohol from plants). It acts like a lightweight oil that spreads easily on your skin, leaving it feeling smooth and soft without a heavy or sticky residue. You'll often find it in moisturizers and serums to improve texture and help other ingredients glide on better.

- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

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
Trioleyl Citrate is an ester formed by combining citric acid with oleyl alcohol. It functions primarily as an emollient and skin conditioning agent, providing a silky, non-greasy feel.
How it works
It sits on the surface of the skin, filling in tiny gaps between skin cells to create a smoother texture. It also helps reduce water loss by forming a light barrier, which supports the skin's natural moisture balance.
Pros
Lightweight feel
Trioleyl Citrate absorbs quickly without leaving a greasy residue, making it ideal for daytime moisturizers and serums.
Gentle on skin
It has a low irritation and comedogenic risk, so it's unlikely to clog pores or cause breakouts for most skin types.
Cons and cautions
Limited moisture for dry skin
As a lightweight emollient, it may not provide enough hydration for very dry or dehydrated skin on its own.
Less research available
Compared to more common emollients like glycerin or squalane, Trioleyl Citrate has fewer published studies on its long-term effects.
Best for
- People with normal to combination skin looking for lightweight moisture
- Those who prefer non-greasy, fast-absorbing products
Use caution if
- Individuals with very dry skin may need richer emollients in addition
