Disodium Myristamido MEA-Sulfosuccinate
INCI: DISODIUM MYRISTAMIDO MEA-SULFOSUCCINATE
A gentle, sulfate-free surfactant that cleanses effectively while being kind to sensitive skin.
In plain English
This ingredient is a mild soap-like molecule that helps water mix with oil and dirt so they can be rinsed away. It's often used in 'gentle' or 'sensitive skin' cleansers because it doesn't strip the skin's natural moisture barrier like harsher detergents can.

Quick decision guide
Useful, but context matters
Disodium Myristamido MEA-Sulfosuccinate 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 Disodium Myristamido 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 Myristamido MEA-Sulfosuccinate is a semi-synthetic surfactant made by combining myristic acid (a fatty acid from coconut or palm oil) with sulfosuccinate chemistry. It belongs to the sulfosuccinate family, known for their mildness.
How it works
It works by reducing the surface tension between water and oil, allowing impurities and excess sebum to be emulsified and washed away. Its large molecular structure makes it less penetrating and less irritating than smaller surfactants like sodium lauryl sulfate.
Pros
Very gentle on skin
Its large molecular structure means it sits on the skin's surface rather than penetrating, reducing the risk of irritation and dryness.
Sulfate-free alternative
Provides effective cleansing without the harshness of sodium lauryl sulfate or sodium laureth sulfate, making it ideal for daily use.
Cons and cautions
Less effective for heavy makeup
If you wear waterproof or long-wear makeup, this ingredient alone may not remove it completely; you may need an oil-based pre-cleanse.
Semi-synthetic origin
While derived from natural fatty acids, it undergoes chemical processing, which may not align with 'all-natural' skincare preferences.
Best for
- People with dry or sensitive skin
- Those looking for a sulfate-free cleanser
Use caution if
- Individuals seeking a deep-cleansing formula for heavy makeup removal (may need a double-cleanse step)
Usage tips
Safety summary
Disodium Myristamido MEA-Sulfosuccinate is considered safe for use in rinse-off cosmetics. It has a low irritation and comedogenic rating, making it suitable for sensitive skin. No significant safety concerns have been reported in regulatory reviews.
Research notes
Studies on sulfosuccinate surfactants indicate they are among the mildest anionic surfactants, with low skin irritation potential. However, specific research on this exact compound is limited; safety is inferred from the broader sulfosuccinate family.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database. No known restrictions at typical concentrations.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Sulfosuccinates are generally biodegradable, but sourcing of myristic acid from palm oil may raise sustainability concerns unless certified sustainable.
Good to know
- Often found in 'soap-free' or 'sulfate-free' cleansers.
- It is biodegradable and considered environmentally friendlier than some harsher surfactants.
