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 C16-22 Acid Amide 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
A synthetic amide derived from fatty acids (C16 to C22 chain length) and monoethanolamine (MEA). It is used primarily as a foam booster and viscosity modifier in rinse-off cleansing products.
How it works
It works by interacting with other surfactants in a formula to stabilize foam and increase the thickness of the product. This makes the cleanser easier to spread and gives a richer, more cushiony lather that feels gentle on skin.
Pros
Enhances lather texture
Creates a dense, creamy foam that feels luxurious and spreads easily, improving the overall cleansing experience.
Low irritation potential
Helps reduce the harshness of stronger surfactants, making cleansers more suitable for daily use without stripping the skin.
Cons and cautions
Synthetic origin
Not derived from natural sources, which may be a drawback for those seeking plant-based or naturally derived ingredients.
Potential for mild dryness
In high concentrations or in formulations without enough moisturizing ingredients, it could contribute to slight dryness over time.
Best for
- Anyone who enjoys a rich, creamy lather in their cleanser
- People with normal to combination skin looking for a mild cleansing option
Use caution if
- Those with very dry or compromised skin barriers who prefer sulfate-free, ultra-gentle cleansers
