Disodium Stearamido MEA-Sulfosuccinate
INCI: DISODIUM STEARAMIDO MEA-SULFOSUCCINATE
A gentle, non-stripping surfactant ideal for sensitive or dry skin types.
In plain English
This ingredient is a mild soap-like molecule that helps cleanse your skin by lifting away dirt, oil, and makeup. Unlike harsher detergents, it is designed to be less irritating and more respectful of your skin's natural moisture barrier. You'll often find it in gentle cleansers, baby washes, and products for sensitive skin.

Quick decision guide
Useful, but context matters
Disodium Stearamido 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 Stearamido 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 Stearamido MEA-Sulfosuccinate is a semi-synthetic surfactant created by combining stearic acid (a fatty acid from plant or animal sources) with sulfosuccinate. It belongs to the sulfosuccinate family, known for their mild cleansing properties.
How it works
In a cosmetic product, this ingredient reduces the surface tension of water, allowing it to mix with oils and dirt on your skin. When you rinse, the dirt and oil are carried away. Its large molecular structure makes it less penetrating and less likely to cause irritation compared to smaller, harsher surfactants.
Pros
Very gentle on skin
Its large molecular structure means it stays on the surface and doesn't penetrate deeply, reducing the chance of irritation or dryness.
Supports moisture barrier
Unlike harsh detergents that can strip oils, this surfactant cleans without compromising the skin's natural protective barrier, leaving it feeling comfortable.
Cons and cautions
Limited cleansing power
It may not fully remove heavy makeup or waterproof products on its own, often requiring a secondary cleanser or oil-based step.
Not fully natural
As a semi-synthetic ingredient, it may not be preferred by those seeking 100% plant-based or naturally derived formulations.
Best for
- People with dry or sensitive skin
- Those looking for a gentle daily cleanser
- Parents choosing mild products for babies or children
Use caution if
- Individuals with known allergies to stearic acid or sulfosuccinates (rare)
Usage tips
Safety summary
Disodium Stearamido MEA-Sulfosuccinate is considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for sensitive skin. Rare allergic reactions are possible, but overall it is well-tolerated.
Research notes
Research supports the mildness of sulfosuccinate surfactants compared to sodium lauryl sulfate. Studies indicate they cause less skin barrier disruption and are less likely to cause irritation in patch tests. However, specific studies on this exact compound are limited, with safety largely inferred from the broader sulfosuccinate class.
Common label clues
- Typical concentration
- 1% to 10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. Generally recognized as safe when used as directed.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Biodegradable and considered less harmful to aquatic life than some traditional surfactants, though always follow local disposal guidelines.
Good to know
- Often used in 'no-tears' shampoos and baby washes due to its mildness.
- It is biodegradable and considered environmentally friendly compared to some harsher surfactants.
