Ingredient review
Sodium/MEA Laureth-2 Sulfosuccinate
INCI: SODIUM/MEA LAURETH-2 SULFOSUCCINATE
A gentle, low-irritation surfactant ideal for sensitive skin and baby care, but it may not foam as richly as harsher cleansers.
In plain English
This is a mild soap-like ingredient that helps water mix with oil and dirt so they can be rinsed away. It is much gentler than traditional sulfates like SLS, so it cleans without leaving your skin feeling tight or dry. You'll often find it in products labeled 'gentle' or 'for sensitive skin.'

Quick decision guide
Useful, but context matters
Sodium/MEA Laureth-2 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 Sodium/MEA Laureth-2 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
A semi-synthetic surfactant derived from lauric acid (from coconut or palm oil) and modified with sulfosuccinate to make it milder. It is often used as a co-surfactant to reduce irritation from stronger cleansers.
How it works
It lowers the surface tension of water, allowing it to penetrate oils and dirt on the skin. The molecules surround grime and lift it away, so it can be rinsed off easily. Because it has a large molecular structure, it is less likely to penetrate the skin barrier, reducing irritation.
Pros
Extremely mild
Rated very low on the irritation scale, making it suitable for eczema-prone or reactive skin.
Eye-friendly
Often used in tear-free baby shampoos because it stings less than other cleansers.
Cons and cautions
Lower foam
Produces a creamy but less voluminous lather, which some users associate with less effective cleansing.
Potential for residue
In hard water or high concentrations, it can leave a slight film on skin or hair.
Best for
- People with dry or sensitive skin
- Those looking for a sulfate-free cleanser
- Parents choosing baby washes
Use caution if
- Individuals seeking a high-foam, bubbly cleanser
- Those with very oily skin who prefer a deep-cleansing sulfate
Usage tips
Safety summary
Considered very safe for topical use. The Cosmetic Ingredient Review (CIR) panel has reviewed sulfosuccinates and found them safe as used in rinse-off products. Mild irritation is rare and usually due to other ingredients in the formula.
Research notes
Studies show sulfosuccinates have low skin and eye irritation potential compared to sodium lauryl sulfate. They are well-tolerated in patch tests on sensitive skin. More research is needed on long-term environmental impact, but current data supports biodegradability.
Common label clues
- Typical concentration
- 1-10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most major markets. No known restrictions at typical concentrations.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby products
- Environmental note
- Derived from renewable plant sources (coconut/palm oil). It is biodegradable, but palm oil sourcing may raise sustainability concerns — look for RSPO-certified options.
Good to know
- This ingredient is often listed near the middle or end of an INCI list, meaning it's not the primary cleanser but a supporting gentle agent.
- It is considered biodegradable and more eco-friendly than some traditional sulfates.
