A gentle, sulfate-free surfactant that cleanses without stripping the skin, ideal for sensitive or dry skin types.
In plain English

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 Laureth-5 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
Disodium Laureth-5 Sulfosuccinate is a semi-synthetic surfactant made by modifying fatty acids from coconut oil. It belongs to the sulfosuccinate family, known for their mildness and ability to produce a rich, creamy foam.
How it works
In a cleanser, this molecule has one end that attracts water and another that attracts oil. When you lather and rinse, it surrounds and lifts away dirt, excess oil, and makeup from your skin, allowing them to be washed off without damaging the skin barrier.
Pros
Extremely mild
One of the gentlest surfactants available, it cleanses effectively without stripping the skin's natural moisture barrier, making it suitable for daily use on sensitive or compromised skin.
Sulfate-free alternative
Provides a rich lather without using harsh sulfates like SLS or SLES, reducing the risk of irritation and dryness for most skin types.
Cons and cautions
May not deep-clean oily skin
Because it is so gentle, it may not remove heavy sebum or waterproof makeup as effectively as stronger surfactants, requiring a double-cleansing routine.
Potential for mild drying at high levels
In formulas where it is the primary surfactant at high concentrations, it can still cause slight dryness, though this is rare and usually mitigated by other ingredients.
Best for
- People with dry or sensitive skin
- Those who prefer sulfate-free cleansers
- Parents looking for gentle baby washes
Use caution if
- Individuals with very oily skin who prefer a stronger, more stripping cleanser
