Hydroxyethyl Carboxymethyl Cocamidopropylamine
INCI: HYDROXYETHYL CARBOXYMETHYL COCAMIDOPROPYLAMINE
A gentle, coconut-derived surfactant that helps create a rich lather without stripping the skin.
In plain English
This ingredient is a mild cleansing agent made from coconut oil. It helps a cleanser foam up nicely and feel thick and creamy, while being gentle enough for sensitive or dry skin. Unlike harsher detergents, it cleans without leaving your skin feeling tight or irritated.

Quick decision guide
Useful, but context matters
Hydroxyethyl Carboxymethyl Cocamidopropylamine 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 Hydroxyethyl Carboxymethyl Cocamidopropylamine.
- 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 semi-synthetic surfactant derived from coconut fatty acids and modified with hydroxyethyl and carboxymethyl groups to improve mildness and water solubility.
How it works
It lowers the surface tension between water and oil, allowing dirt and excess sebum to be rinsed away. It also stabilizes foam and thickens the product formula, giving a luxurious, creamy lather.
Pros
Very gentle on skin
Unlike sodium lauryl sulfate, this surfactant cleans without disrupting the skin barrier, making it ideal for sensitive or eczema-prone skin.
Pleasant sensory feel
It boosts foam and thickens the formula, so your cleanser feels creamy and luxurious rather than watery or thin.
Cons and cautions
Not for water-free products
This ingredient requires water to function as a surfactant, so it cannot be used in oil-based or anhydrous cleansers.
Potential for mild dryness at high levels
In very high concentrations (above 10%), it may still cause slight tightness, though far less than traditional sulfates.
Best for
- People with sensitive or dry skin
- Anyone looking for a sulfate-free, gentle cleanser
Use caution if
- Those with known coconut oil allergy (rare)
- Formulators needing a completely water-free system
Usage tips
Safety summary
Hydroxyethyl Carboxymethyl Cocamidopropylamine is considered safe for use in rinse-off cosmetics at typical concentrations. It has a low irritation and sensitization potential, though individuals with coconut allergies should exercise caution.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel and other bodies support the use of similar amphoteric surfactants as safe and mild. Direct studies on this specific ingredient are limited, but its chemical class is well-documented.
Common label clues
