Disodium Cocamido MEA-Sulfosuccinate
INCI: Disodium Cocamido MEA-Sulfosuccinate
A gentle, coconut-derived surfactant that cleanses without stripping the skin, making it ideal for sensitive or dry skin types.
In plain English
This ingredient is a mild soap-like molecule made from coconut oil. It helps water mix with oil and dirt so they can be rinsed away, but it's much less harsh than traditional sulfates like SLS. It creates a soft, creamy foam and is often used in gentle cleansers for sensitive 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 Disodium Cocamido MEA-Sulfosuccinate.
- 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
Disodium Cocamido MEA-Sulfosuccinate is a semi-synthetic surfactant, meaning it's made by chemically modifying fatty acids from coconut oil. It belongs to the sulfosuccinate family, known for being exceptionally mild on skin and eyes.
How it works
It works by reducing the surface tension between water and oil, allowing dirt, sebum, and makeup to be lifted from the skin and rinsed away. Its large molecular structure makes it less penetrating and less irritating than smaller, harsher surfactants.
Pros
Exceptionally mild
This surfactant is one of the gentlest available, making it a top choice for sensitive skin, baby washes, and dermatologist-recommended cleansers.
Creamy foam
Unlike some mild cleansers that produce little lather, this ingredient creates a rich, creamy foam that feels pleasant and luxurious on the skin.
Cons and cautions
Less effective on heavy makeup
On its own, it may struggle to remove long-wear or waterproof makeup, so it's often paired with other cleansers or used in a double-cleanse routine.
Potential for slight drying
While very gentle, if used at high concentrations or without moisturizing co-ingredients, it can still leave skin feeling slightly tight or dry.
Best for
- People with dry, sensitive, or reactive skin
- Those looking for a sulfate-free, gentle daily cleanser
Use caution if
- Individuals with known coconut oil allergies (rare)
- Those seeking a high-foam, squeaky-clean feel (may prefer stronger surfactants)
