Ingredient review
Disodium Deceth-5 Sulfosuccinate
INCI: Disodium Deceth-5 Sulfosuccinate
A gentle, sulfate-free surfactant that effectively cleanses without over-drying, making it a good choice for sensitive or dry skin.
In plain English
Disodium Deceth-5 Sulfosuccinate is a synthetic cleansing ingredient that helps water mix with oil and dirt so they can be rinsed away. Unlike harsher detergents like sodium lauryl sulfate, it is known for being mild on the skin and eyes, which is why it often appears in gentle cleansers, baby washes, and products for sensitive skin. It creates a soft, creamy lather and leaves skin feeling clean but not tight or stripped.

Quick decision guide
Useful, but context matters
Disodium Deceth-5 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 Deceth-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.
- 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 derived from a fatty alcohol (decyl alcohol) and sulfosuccinic acid. It belongs to the sulfosuccinate family, which are known for their mild cleansing properties.
How it works
It reduces the surface tension between water and oils, allowing them to mix. This helps lift dirt, sebum, and makeup from the skin's surface so they can be rinsed away with water. Its large molecular structure makes it less penetrating and therefore less irritating than smaller surfactants.
Pros
Very mild on skin
Its large molecular structure makes it less likely to penetrate and irritate the skin barrier, ideal for sensitive or compromised skin.
Sulfate-free alternative
Provides effective cleansing without using sodium lauryl sulfate or sodium laureth sulfate, which can be overly drying for some.
Cons and cautions
Synthetic origin
Not derived from natural sources, which may be a drawback for consumers seeking 100% natural or organic formulations.
Potential for slight dryness
In very high concentrations or with frequent use, it may still cause mild dryness, especially for already dehydrated skin.
Best for
- People with dry or sensitive skin
- Those looking for a sulfate-free cleanser
- Parents choosing gentle baby washes
Use caution if
- Individuals who strictly avoid all synthetic ingredients
- Those with known rare allergies to sulfosuccinates
