Ingredient review
Linoleamide MEA
INCI: Linoleamide MEA
A foam booster and thickener for cleansers, but may be mildly irritating and potentially pore-clogging for some skin types.
In plain English
Linoleamide MEA is a semi-synthetic ingredient made from linoleic acid (an omega-6 fatty acid found in plant oils) and ethanolamine. It is added to cleansers and shampoos to create a rich, stable lather and to thicken the product so it feels more luxurious. While it helps the product perform well, it can be slightly drying or irritating for sensitive skin and has a moderate chance of clogging pores.

Quick decision guide
Useful, but context matters
Linoleamide MEA can be useful, but watch for some irritation potential and possible clogging concerns.
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 Linoleamide MEA.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
Clogging risk
moderateMay be fine for many users but deserves caution if you are breakout-prone.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Linoleamide MEA is a fatty acid amide derived from linoleic acid, an essential omega-6 fatty acid. It is chemically modified to improve its ability to boost foam and control viscosity in cleansing products.
How it works
In a cosmetic product, Linoleamide MEA acts as a co-surfactant. It helps stabilize foam bubbles, making the lather richer and creamier. It also increases the thickness of the liquid, giving the product a more substantial feel. It works alongside primary surfactants (like sodium lauryl sulfate) to improve cleansing performance.
Pros
Enhances foam quality
Creates a dense, stable lather that makes cleansing feel more satisfying and effective.
Improves product texture
Thickens the formula so it feels richer and more luxurious on the skin.
Cons and cautions
Potential irritation
Can cause mild stinging or dryness, especially for those with sensitive or compromised skin barriers.
May clog pores
Has a moderate comedogenic rating, meaning it could contribute to breakouts in acne-prone individuals.
Best for
- People who enjoy a foamy, creamy cleanser
- Those with normal to oily skin looking for effective cleansing
Use caution if
- Individuals with very dry, sensitive, or acne-prone skin who may experience irritation or breakouts
Usage tips
Safety summary
Generally considered safe for most people in rinse-off products at typical concentrations. However, it has moderate irritation and comedogenic potential, so those with sensitive or acne-prone skin should use with caution.
Research notes
Limited direct studies on Linoleamide MEA specifically. Its safety profile is inferred from related fatty acid amides and surfactant chemistry. The Cosmetic Ingredient Review (CIR) panel has evaluated similar ingredients and found them safe when formulated to be non-irritating.
Common label clues
- Typical concentration
- 0.5% to 3%
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) with no specific concentration restrictions, though formulators typically keep levels low to minimize irritation.
- Common uses
- Cleansers, Shampoos, Body washes, Facial washes
- Environmental note
- Semi-synthetic; derived from plant oils but chemically modified. Biodegradability is moderate, and it may contribute to aquatic toxicity in high concentrations.
Good to know
- Linoleamide MEA is different from linoleic acid; the MEA modification changes its function and skin compatibility.
- It is often found in sulfate-based cleansers to improve the feel of the lather.
