Di-TEA-Oleamido PEG-2 Sulfosuccinate
INCI: DI-TEA-OLEAMIDO PEG-2 SULFOSUCCINATE
A gentle synthetic surfactant that cleanses without stripping the skin, often used in milder formulas.
In plain English
This is a mild soap-like ingredient that helps water mix with oil and dirt so they can be rinsed away.

Quick decision guide
Useful, but context matters
Di-TEA-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 Di-TEA-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.

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 derived from oleic acid (a fatty acid found in olive oil) and sulfosuccinic acid, modified with PEG and TEA to make it water-soluble and mild.
How it works
It reduces the surface tension between water and oil, allowing oils and dirt on the skin or hair to be emulsified and washed away. Its large molecular structure makes it less penetrating and therefore less irritating than smaller surfactants.
Pros
Very gentle on skin
Its large molecular structure means it doesn't penetrate the skin barrier, reducing the risk of irritation and dryness compared to harsher surfactants like sodium lauryl sulfate.
Good foam quality
It produces a stable, creamy lather that feels luxurious and satisfying, making it a popular choice for premium gentle cleansers and baby shampoos.
Cons and cautions
Not for heavy-duty cleansing
Because it's so mild, it may not effectively remove heavy makeup, waterproof sunscreen, or excess sebum on its own, often requiring a second cleanse or a stronger partner surfactant.
Synthetic and not biodegradable
As a synthetic compound, it may not appeal to those seeking natural or eco-friendly formulations, and its environmental impact is less favorable than some plant-based alternatives.
Best for
- People with dry or sensitive skin
- Those looking for a sulfate-free cleanser
Use caution if
- Individuals seeking a very deep-cleansing or clarifying wash
Usage tips
