Disodium Stearyl Sulfosuccinamate
INCI: DISODIUM STEARYL SULFOSUCCINAMATE
A mild, sulfate-free surfactant that cleanses without stripping the skin barrier.
In plain English
Disodium Stearyl Sulfosuccinamate is a gentle cleansing ingredient that helps remove dirt and oil from your skin without the harshness of traditional sulfates. It's often used in products labeled 'sulfate-free' because it creates a soft lather and rinses cleanly, leaving skin feeling comfortable rather than tight or dry.

Quick decision guide
Useful, but context matters
Disodium Stearyl Sulfosuccinamate 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 Stearyl Sulfosuccinamate.
- 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 synthetic surfactant (cleansing agent) made from stearyl alcohol and sulfosuccinic acid. It belongs to the sulfosuccinate family, known for being milder than many other cleansing ingredients.
How it works
It works by reducing the surface tension between water and oil, allowing impurities to be lifted away from the skin and rinsed off. Its large molecular structure makes it less penetrating and therefore less irritating than smaller, harsher surfactants.
Pros
Very gentle on skin
Its large molecular structure means it's less likely to penetrate and irritate the skin barrier, making it ideal for sensitive or dry skin types.
Sulfate-free option
Provides effective cleansing without sodium lauryl sulfate (SLS) or sodium laureth sulfate (SLES), which can be drying for some people.
Cons and cautions
Lower foaming action
Produces a less dramatic lather than traditional sulfates, which may feel less satisfying to those who associate foam with cleanliness.
Limited oil removal
May struggle to dissolve heavy oils, waterproof makeup, or long-wearing sunscreens, often requiring a double-cleansing step.
Best for
- People with dry or sensitive skin
- Those looking for a sulfate-free cleanser
Use caution if
- Individuals who prefer a rich, bubbly lather
- Those needing a heavy-duty makeup remover
Usage tips
Safety summary
Disodium Stearyl Sulfosuccinamate is considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for sensitive skin. No significant safety concerns have been raised by regulatory bodies.
Research notes
Research on sulfosuccinates indicates they are among the mildest surfactants available, with low potential for skin irritation and barrier disruption. Most evidence comes from comparative surfactant studies and safety assessments rather than large-scale clinical trials.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Synthetic ingredient; biodegradability data is limited but sulfosuccinates are generally considered less persistent than some other surfactants.
Good to know
- Often found in 'sulfate-free' and 'gentle' cleanser formulas.
- Can be combined with other mild surfactants to improve cleansing power without increasing irritation.
