Disodium Tridecylsulfosuccinate
INCI: Disodium Tridecylsulfosuccinate
A gentle, sulfate-free surfactant that cleans effectively without stripping the skin's natural moisture barrier.
In plain English
Disodium Tridecylsulfosuccinate is a synthetic cleansing ingredient that helps water mix with oil and dirt on your skin. Unlike harsh soaps or sulfates, it cleans without stripping away too much of your skin's natural oils, making it a good choice for sensitive or dry skin. You'll find it in many gentle face washes and baby shampoos.

Quick decision guide
Useful, but context matters
Disodium Tridecylsulfosuccinate 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 Tridecylsulfosuccinate.
- 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 synthetic surfactant (cleansing agent) derived from tridecyl alcohol and sulfosuccinic acid. It belongs to the sulfosuccinate family, known for being milder than traditional sulfates like sodium lauryl sulfate.
How it works
It reduces the surface tension between water and oil, allowing water to penetrate and lift away dirt, sebum, and makeup. Its large molecular structure makes it less penetrating into the skin, which reduces irritation potential.
Pros
Gentle on skin
Its large molecular structure means it doesn't penetrate deeply, reducing the risk of irritation and dryness.
Sulfate-free option
Provides effective cleansing without the harshness of sodium lauryl sulfate, making it ideal for daily use.
Cons and cautions
Synthetic origin
It is not derived from natural sources, which may be a drawback for those seeking all-natural skincare.
Potential for drying at high levels
In formulas with very high concentrations and without added moisturizers, it can still cause some dryness.
Best for
- People with sensitive or easily irritated skin
- Those looking for a sulfate-free cleanser
Use caution if
- Individuals who prefer exclusively natural or plant-derived ingredients
Usage tips
