Ingredient review
Disodium PEG-8 Lauryl Dimethicone Sulfosuccinate
INCI: DISODIUM PEG-8 LAURYL DIMETHICONE SULFOSUCCINATE
A mild, silicone-based surfactant that cleanses without stripping the skin barrier, ideal for sensitive or dry skin.
In plain English
This ingredient is a special type of cleanser that combines a silicone (which gives a silky feel) with a mild soap-like molecule. It helps remove dirt, oil, and makeup while leaving skin feeling soft and not tight or dry. Because it is very gentle, it is often used in products for sensitive skin or in baby shampoos.

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 PEG-8 Lauryl Dimethicone 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 semi-synthetic surfactant created by modifying dimethicone (a silicone) with a sulfosuccinate group, making it water-soluble and able to lift away impurities.
How it works
It lowers the surface tension between water and oil, allowing oils and dirt to be rinsed away. The silicone portion leaves a light, non-greasy film that helps skin feel smooth and conditioned after washing.
Pros
Extremely mild cleansing
This surfactant is one of the gentlest options available, making it ideal for compromised or sensitive skin that reacts to stronger cleansers.
Leaves skin soft
The silicone component deposits a light conditioning film, so skin feels smooth and hydrated after washing, not tight or dry.
Cons and cautions
Not for heavy-duty cleansing
It may struggle to remove heavy makeup or waterproof sunscreen, often requiring a double-cleanse routine.
Contains silicone
Some users avoid silicones due to personal preference or concerns about buildup, though this type is typically water-soluble and rinses clean.
Best for
- People with dry, sensitive, or eczema-prone skin
- Those looking for a gentle daily cleanser that doesn't strip moisture
Use caution if
- Individuals who prefer silicone-free formulations
