Ingredient review
Ethyl Linoleate
INCI: Ethyl Linoleate
A gentle, non-greasy emollient derived from linoleic acid that helps soften and smooth skin without clogging pores.
In plain English
Ethyl linoleate is a skincare ingredient made by combining linoleic acid (a fatty acid found in many plant oils) with ethanol. It works as an emollient, meaning it helps soften and smooth the skin by filling in the tiny gaps between skin cells. Unlike some heavier oils, it feels light and non-greasy, making it a good choice for people with oily or combination skin who still want moisture. It also has mild antioxidant properties because linoleic acid is a building block of the skin's natural barrier.

Quick decision guide
Useful, but context matters
Ethyl Linoleate 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 Ethyl Linoleate.
- 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
Ethyl linoleate is the ethyl ester of linoleic acid, an omega-6 fatty acid. It is typically produced by reacting linoleic acid (often sourced from sunflower, safflower, or other vegetable oils) with ethanol. The result is a stable, lightweight oil that spreads easily on the skin.
How it works
When applied to the skin, ethyl linoleate sits on the surface and fills in rough or dry patches, creating a smoother feel. It also penetrates the upper layers of the skin, where it can be broken down into linoleic acid. Linoleic acid is a key component of ceramides, which are essential for a healthy skin barrier. By supporting barrier function, ethyl linoleate helps reduce water loss and keeps skin hydrated.
Pros
Lightweight feel
Unlike heavier oils, ethyl linoleate absorbs quickly and leaves no sticky residue, making it ideal for daytime use or under makeup.
Low clog risk
It has a low comedogenic rating, so it is unlikely to clog pores or cause breakouts, even in acne-prone skin.
Cons and cautions
Milder barrier support
While it supports the skin barrier, it is not as potent as pure linoleic acid for repairing damaged barrier function.
Rare sensitivity
A very small number of people may experience mild irritation or redness, especially if they have extremely sensitive or reactive skin.
Best for
- People with oily or combination skin who want light moisture
- Those looking for a non-comedogenic emollient
- Anyone wanting to support their skin barrier without heavy oils
Use caution if
- Individuals with a known allergy to linoleic acid or ethyl esters (very rare)
Usage tips
Safety summary
Ethyl linoleate is considered safe for cosmetic use at typical concentrations. It has low irritation and comedogenic potential. Rare allergic reactions are possible but uncommon.
Research notes
Studies on linoleic acid (the parent compound) show it supports skin barrier function and reduces water loss. Direct research on ethyl linoleate is limited, but its chemical similarity to linoleic acid suggests comparable benefits with improved stability and feel.
Common label clues
- Typical concentration
- 0.5% to 5% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most major markets. Generally recognized as safe when used as directed.
- Common uses
- Moisturizers, Serums, Body lotions, Facial oils
- Environmental note
- Ethyl linoleate is biodegradable and typically derived from renewable plant sources, making it a relatively eco-friendly choice.
Good to know
- Ethyl linoleate is often used in 'oil-free' formulations because it feels lighter than many natural oils.
- It is sometimes listed as part of a blend of esters in multi-ingredient emollient complexes.
