Ingredient review
Myristamide MEA
INCI: MYRISTAMIDE MEA
A mild foam booster that helps cleansers feel richer, but offers no direct skin benefit beyond texture.
In plain English
Myristamide MEA is a synthetic ingredient added to cleansers and shampoos to create a thicker, creamier lather. It doesn't clean your skin or hair by itself, but it helps the product feel more luxurious and spread easily. Think of it as a texture helper that makes your wash feel nicer, but it doesn't contribute to the actual cleansing or moisturizing.

Quick decision guide
Useful, but context matters
Myristamide 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 Myristamide 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
Myristamide MEA is a fatty acid amide derived from myristic acid (a saturated fatty acid found in coconut oil and palm oil) and monoethanolamine. It is produced synthetically and used primarily as a foam booster and thickener in rinse-off products.
How it works
In a cosmetic formula, Myristamide MEA interacts with other surfactants to stabilize and increase foam volume, creating a denser, more stable lather. It also increases the viscosity (thickness) of the product, giving it a richer, more luxurious feel during use. It does not have any direct cleansing, moisturizing, or skin-repairing properties.
Pros
Enhances foam quality
Creates a dense, creamy lather that many people associate with effective cleansing, making the product feel more pleasant to use.
Improves product texture
Thickens the formula so it feels richer and more substantial in your hand, which can improve the overall user experience.
Cons and cautions
No direct skin benefit
Myristamide MEA only affects foam and thickness; it doesn't moisturize, soothe, or protect the skin, so it's purely a cosmetic additive.
Potential sustainability issues
Often derived from palm oil, which can be linked to deforestation and habitat loss unless sourced from certified sustainable suppliers.
Best for
- Anyone who enjoys a rich, creamy lather in their cleanser or shampoo
- People with normal to oily skin looking for a satisfying wash experience
Use caution if
- Those with very dry or compromised skin who prefer non-foaming, gentle cleansers
- Individuals avoiding synthetic ingredients or palm-derived components
Usage tips
Safety summary
Myristamide MEA is considered safe for use in rinse-off cosmetics at typical concentrations. It has low irritation and comedogenic potential, though very sensitive skin may experience mild dryness with frequent use.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that Myristamide MEA is safe as used in rinse-off products. No significant toxicity or sensitization concerns have been identified in published studies.
Common label clues
- Typical concentration
- 0.5% to 3%
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU (CosIng), and many other regions. Generally recognized as safe at typical concentrations.
- Common uses
- Cleansers, Shampoos, Body washes, Facial washes
- Environmental note
- May be derived from palm oil; look for RSPO-certified or sustainably sourced versions if environmental impact is a concern.
Good to know
- Myristamide MEA is considered safe by major regulatory bodies at typical use levels.
- It is not a primary surfactant; it works alongside stronger cleansers to improve foam.
