Disodium Oleamido PEG-2 Sulfosuccinate
INCI: DISODIUM OLEAMIDO PEG-2 SULFOSUCCINATE
A gentle, foaming surfactant that effectively cleanses without stripping the skin, making it ideal for sensitive skin and baby care.
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 is designed to be less harsh than traditional soaps, 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
Disodium Oleamido PEG-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 Disodium Oleamido PEG-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
Disodium Oleamido PEG-2 Sulfosuccinate is a semi-synthetic surfactant created by combining oleic acid (a fatty acid from oils like olive or palm) with a sulfosuccinate group. It belongs to the sulfosuccinate family, known for producing rich, stable foam with very low irritation potential.
How it works
In a cosmetic product, this molecule has a water-loving head and an oil-loving tail. When you lather a cleanser containing it, the tails grab onto dirt, oil, and makeup, while the heads stay in the water. Rinsing then washes away the entire complex, leaving skin clean. Its large molecular structure makes it too big to penetrate deeply into the skin, so it stays on the surface and is very gentle.
Pros
Exceptionally gentle cleansing
Unlike sodium lauryl sulfate, this surfactant has a large molecular structure that doesn't penetrate the skin barrier, so it cleans without causing irritation or tightness.
Rich, stable foam
It produces a creamy, luxurious lather that feels pleasant on the skin, making it a favorite in high-end gentle cleansers and baby products.
Cons and cautions
Potential palm oil sourcing
The oleic acid used may come from palm oil, which has environmental concerns related to deforestation unless certified sustainable.
PEG content concerns
As a PEG compound, there is a small risk of contamination with 1,4-dioxane during manufacturing, though reputable brands purify their ingredients to safe levels.
Best for
- People with dry or sensitive skin who find traditional cleansers too stripping
- Parents looking for a gentle, tear-free baby wash or shampoo
Use caution if
- Those who strictly avoid all PEG-derived ingredients for personal reasons
Usage tips
Safety summary
Disodium Oleamido PEG-2 Sulfosuccinate is considered safe for use in rinse-off cosmetics at typical concentrations. It has a very low irritation and sensitization profile. The main safety consideration is the potential for 1,4-dioxane contamination from the PEG component, but this is controlled by good manufacturing practices and is present only in trace amounts in well-made products.
Research notes
Sulfosuccinate surfactants, including this one, have been reviewed by the Cosmetic Ingredient Review (CIR) panel and found safe for cosmetic use. Studies show they are significantly less irritating to skin and eyes than traditional anionic surfactants like SLS. Most evidence comes from industry safety data and dermatological testing rather than large-scale independent clinical trials.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission. The Cosmetic Ingredient Review (CIR) panel has deemed sulfosuccinates safe as used in rinse-off products.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby washes
- Environmental note
- Sourcing of the oleic acid can involve palm oil; look for products with RSPO (Roundtable on Sustainable Palm Oil) certification if this is a concern.
Good to know
- This ingredient is often used alongside other mild surfactants to boost foam without increasing irritation.
- It is considered biodegradable and is commonly found in 'tear-free' baby shampoos.
