Ingredient review
Oleamide MEA
INCI: OLEAMIDE MEA
A mild foam booster that helps cleansers feel richer, but offers no direct skin benefit beyond texture.
In plain English
Oleamide MEA is an ingredient added to cleansers and shampoos to make them foam more and feel thicker or creamier. It is made from oleic acid, a fatty acid found in olive oil and other plant oils. While it improves the sensory experience of washing, it does not moisturize or treat the skin on its own.

Quick decision guide
Useful, but context matters
Oleamide MEA 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 Oleamide 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
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
Oleamide MEA is a semi-synthetic compound created by reacting oleic acid (a fatty acid from plant oils) with monoethanolamine. It belongs to a class of ingredients called alkanolamides, which are used to boost foam and adjust the thickness of liquid cleansers.
How it works
In a cosmetic product, Oleamide MEA sits at the interface between water and oil, helping to stabilize the formula and increase the volume and stability of foam. It also thickens the liquid, giving it a richer, more luxurious feel when pumped or squeezed out.
Pros
Improves foam quality
Creates a dense, stable foam that many people associate with a thorough clean, making the washing experience more pleasant.
Mild on skin
Compared to some other foam boosters, Oleamide MEA is considered low-irritation and is generally well-tolerated even with daily use.
Cons and cautions
No skin benefit
Oleamide MEA only affects the feel and foam of a product; it does not hydrate, soothe, or treat the skin in any way.
Source transparency
The origin of the oleic acid (plant or animal) is not always disclosed on labels, which can be a concern for vegans or those avoiding animal-derived ingredients.
Best for
- Anyone who enjoys a rich, foamy cleanser
- People with normal to oily skin looking for a satisfying wash experience
Use caution if
- Those seeking purely plant-based or vegan-certified products (source may vary)
- Individuals with very sensitive skin who prefer minimal-ingredient cleansers
Usage tips
Safety summary
Oleamide MEA is considered safe for use in rinse-off cosmetic products at typical concentrations. It has low irritation and sensitization potential. However, as with any ingredient, individuals with known sensitivities should check product labels.
Research notes
Research on Oleamide MEA specifically is limited, but the broader class of alkanolamides has been reviewed by the Cosmetic Ingredient Review panel and found safe in rinse-off products. No significant toxicity or health concerns have been identified at cosmetic use levels.
Common label clues
- Typical concentration
- Typically 1–5% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed related alkanolamides and found them safe as used.
- Common uses
- Cleansers, Shampoos, Body washes, Facial washes
- Environmental note
- Oleamide MEA is biodegradable, but its production may involve monoethanolamine, which requires careful handling. Sourcing from plant-based oleic acid is more sustainable than animal-derived sources.
Good to know
- Oleamide MEA is often used alongside other mild surfactants to reduce overall irritation potential.
- It is not the same as oleamide (a different compound used in some cosmetics and plastics).
