Tetrasodium Dicarboxyethyl Stearyl Sulfosuccinamate
INCI: Tetrasodium Dicarboxyethyl Stearyl Sulfosuccinamate
A gentle, sulfate-free surfactant that cleanses effectively with low irritation potential, ideal for sensitive skin.
In plain English
This is a synthetic cleansing ingredient that helps water mix with oil and dirt so they can be rinsed away. Unlike harsher sulfates, it is designed to be mild on the skin and is often used in products for sensitive or dry skin. It creates a soft, creamy lather without stripping the skin's natural moisture barrier.

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 anionic surfactant derived from stearic acid and sulfosuccinic acid, modified to be larger and milder than traditional sulfates.
How it works
It reduces the surface tension between water and oil, allowing impurities to be emulsified and washed away. Its large molecular structure makes it less penetrating and less irritating to the skin barrier.
Pros
Very gentle on skin
Its large molecular structure means it stays on the surface and doesn't penetrate, reducing irritation risk even for sensitive skin types.
Sulfate-free alternative
Provides effective cleansing without the harshness of sodium lauryl sulfate, making it a popular choice for mild formulations.
Cons and cautions
Synthetic origin
It is manufactured in a lab, which may be a downside for consumers seeking 100% natural or organic skincare.
Limited standalone cleansing power
May not thoroughly remove heavy makeup or waterproof sunscreen on its own, often requiring co-surfactants for a deeper clean.
Best for
- People with sensitive or easily irritated skin
- Those looking for a sulfate-free cleanser
- Individuals with dry or compromised skin barriers
Use caution if
- Those who prefer exclusively natural or plant-derived ingredients
