Ingredient review
Diammonium Lauramido-MEA Sulfosuccinate
INCI: DIAMMONIUM LAURAMIDO-MEA SULFOSUCCINATE
A gentle, sulfate-free surfactant that cleans without stripping the skin barrier, ideal for sensitive or dry 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. Unlike harsher cleansers (like sodium lauryl sulfate), it is much less likely to cause irritation or dryness, making it a popular choice for gentle face washes and baby shampoos.

Quick decision guide
Useful, but context matters
Diammonium Lauramido-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 Diammonium Lauramido-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
Diammonium Lauramido-MEA Sulfosuccinate is a semi-synthetic surfactant made by combining lauric acid (from coconut oil) with sulfosuccinate chemistry. It belongs to the sulfosuccinate family, known for producing a creamy, low-foam lather with very low irritation potential.
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 too big to penetrate deeply into the skin, so it stays on the surface and cleans gently without disrupting the skin barrier.
Pros
Very gentle on skin
Its large molecular structure means it cleans without penetrating or stripping the skin's natural oils, reducing the risk of tightness or irritation.
Sulfate-free alternative
Provides a creamy foam without using sodium lauryl sulfate (SLS) or sodium laureth sulfate (SLES), which are known to be more drying for many skin types.
Cons and cautions
Lower cleansing power
It is not as effective at dissolving heavy oils, waterproof makeup, or long-wear sunscreen, so you may need a double-cleansing step.
Less foam volume
Some users prefer a rich, bubbly lather; this ingredient produces a softer, creamier foam that might feel less satisfying to those accustomed to high-foam cleansers.
Best for
- People with dry, sensitive, or eczema-prone skin looking for a gentle daily cleanser
- Those who prefer sulfate-free, low-irritation cleansing products
Use caution if
- Individuals who need a deep-cleansing formula to remove heavy makeup or sunscreen may find it insufficient on its own
Usage tips
Safety summary
Diammonium Lauramido-MEA Sulfosuccinate has a strong safety profile with very low irritation and sensitization potential. It is widely used in baby care and sensitive-skin products. No significant safety concerns have been raised by regulatory bodies.
Research notes
Research on sulfosuccinate surfactants consistently shows they are among the mildest cleansing agents available. Studies indicate they cause less disruption to skin barrier lipids and lower levels of protein denaturation compared to SLS. However, direct clinical studies on this specific compound are limited.
Common label clues
- Typical concentration
- 1% to 10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most major markets. Generally recognized as safe when used as directed in rinse-off products.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Sulfosuccinates are generally considered biodegradable and have lower aquatic toxicity compared to some conventional surfactants, though full environmental impact depends on formulation and concentration.
Good to know
- Often found in 'sulfate-free' and 'gentle' labeled cleansers alongside other mild surfactants like coco-glucoside.
- It is biodegradable and considered environmentally safer than some traditional surfactants.
