Ingredient review
Disodium PEG-12 Dimethicone Sulfosuccinate
INCI: DISODIUM PEG-12 DIMETHICONE SULFOSUCCINATE
A gentle, silicone-based surfactant that cleanses effectively while leaving skin feeling soft and non-stripped.
In plain English
This ingredient is a mild cleansing agent made by combining silicone (dimethicone) with a gentle soap-like molecule (sulfosuccinate) and a water-loving chain (PEG-12). It helps wash away dirt, oil, and makeup without making your skin feel tight or dry. Because it contains silicone, it can also leave a light, silky feel on the skin after rinsing.

Quick decision guide
Useful, but context matters
Disodium PEG-12 Dimethicone 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 PEG-12 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.
- 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
Disodium PEG-12 Dimethicone Sulfosuccinate is a semi-synthetic surfactant derived from silicone (dimethicone), polyethylene glycol (PEG-12), and sulfosuccinic acid. It belongs to the sulfosuccinate family, known for being milder than traditional sulfates like SLS.
How it works
In a cleanser, this molecule has both water-loving and oil-loving parts. The silicone portion helps it spread easily and gently lift oils and impurities from the skin. The sulfosuccinate part creates a mild foam that rinses away dirt without disrupting the skin's natural moisture barrier.
Pros
Very gentle on skin
Unlike harsh sulfates, this surfactant cleanses without stripping the skin's natural oils, making it ideal for dry or sensitive skin types.
Leaves a silky feel
The silicone component gives a smooth, soft after-feel on the skin, which can be especially pleasant in a cleanser or body wash.
Cons and cautions
Contains PEGs
PEG compounds can be contaminated with ethylene oxide during manufacturing, though reputable brands ensure purity. Some consumers prefer to avoid them.
Silicone content
If you are avoiding silicones for environmental or personal reasons, this ingredient may not fit your preferences.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Anyone who wants a non-stripping, soft-feeling wash
Use caution if
- Those who prefer to avoid silicones in their routine
- Individuals who avoid PEG compounds due to personal preference
Usage tips
Safety summary
Disodium PEG-12 Dimethicone Sulfosuccinate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential. The main concerns are related to PEG purity and silicone biodegradability, which are generally well-managed by responsible manufacturers.
Research notes
Sulfosuccinate surfactants are well-documented as mild alternatives to sulfates. Specific studies on this PEG-12 dimethicone variant are limited, but the ingredient class is recognized as safe by cosmetic safety panels such as the Cosmetic Ingredient Review (CIR).
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) at typical concentrations. No known restrictions.
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- Silicone-based surfactants may have lower biodegradability than plant-based alternatives, but this specific compound is not widely studied for environmental impact.
Good to know
- This ingredient is often used in 'gentle' or 'hydrating' cleansers marketed for sensitive skin.
- It is not a foaming powerhouse—expect a low, creamy lather rather than big bubbles.
