Triisopropyl Trilinoleate
INCI: Triisopropyl Trilinoleate
A lightweight synthetic ester that softens skin without clogging pores, ideal for oily or combination skin types.
In plain English
Triisopropyl Trilinoleate is a man-made oil-like ingredient that spreads easily on the skin, leaving it feeling smooth and soft without a heavy or greasy residue. It's often used in moisturizers, lipsticks, and foundations to improve texture and help other ingredients glide on better.

Quick decision guide
Useful, but context matters
Triisopropyl Trilinoleate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Triisopropyl Trilinoleate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
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
Triisopropyl Trilinoleate is a synthetic ester derived from linoleic acid (a fatty acid found in plant oils) and isopropyl alcohol. It is designed to mimic the feel of natural oils but with better stability and a lighter texture.
How it works
It sits on the skin's surface, filling in tiny gaps between skin cells to create a smooth, even layer. This reduces water loss and gives the skin a soft, supple feel. Its lightweight structure allows it to absorb quickly without leaving a sticky or oily film.
Pros
Lightweight feel
Unlike heavier oils, Triisopropyl Trilinoleate absorbs quickly and leaves no greasy residue, making it comfortable for daily wear 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, which is great for acne-prone skin.
Cons and cautions
Synthetic origin
It is man-made, which may be a turn-off for consumers seeking 100% natural or plant-based skincare products.
Limited research
While generally considered safe, there are fewer long-term studies on this specific ester compared to more common emollients like glycerin or squalane.
Best for
- People with oily or combination skin who want lightweight moisture
- Anyone looking for a non-comedogenic emollient in makeup or skincare
Use caution if
- Those who strictly avoid synthetic ingredients
- Individuals with known sensitivity to esters (rare)
Usage tips
Safety summary
Triisopropyl Trilinoleate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. Rare allergic reactions are possible, as with any ingredient.
Research notes
Research on Triisopropyl Trilinoleate is limited but consistent with other fatty acid esters. It is recognized as a safe emollient by industry panels. No significant adverse effects have been reported in cosmetic use.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has evaluated similar esters and found them safe at typical concentrations.
- Common uses
- Moisturizers, Lip products, Makeup foundations, Sunscreens
- Environmental note
- As a synthetic ingredient, its environmental impact depends on manufacturing processes. It is not biodegradable in the same way as natural plant oils.
Good to know
- Triisopropyl Trilinoleate is often used in combination with other emollients to balance texture.
- It is stable and resists oxidation, giving products a longer shelf life.
