Ingredient review
Sodium Dimethicone PEG-7 Acetyl Methyltaurate
INCI: SODIUM DIMETHICONE PEG-7 ACETYL METHYLTAURATE
A gentle silicone-based surfactant that cleanses without stripping the skin, making it a good option for sensitive or dry skin types.
In plain English
This ingredient is a hybrid of silicone and a mild cleansing agent. It helps products foam gently, rinse away dirt and oil, and leave skin feeling smooth rather than tight or dry. Because it's derived from silicone, it also adds a silky, soft after-feel.

Quick decision guide
Useful, but context matters
Sodium Dimethicone PEG-7 Acetyl Methyltaurate 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 Sodium Dimethicone PEG-7 Acetyl Methyltaurate.
- 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 semi-synthetic compound that combines a silicone backbone (dimethicone) with a water-loving PEG chain and a mild amino-acid-derived surfactant (methyltaurate). This structure allows it to act as both an emulsifier and a gentle cleanser.
How it works
In a formula, it reduces the surface tension between water and oil, helping them mix so that dirt and makeup can be rinsed away. Its silicone portion deposits a thin, non-greasy film on skin or hair, which can improve texture and reduce friction.
Pros
Gentle on skin
Unlike harsher sulfates, this surfactant cleans without stripping natural oils, making it ideal for daily use on sensitive or dry skin.
Smooth after-feel
The silicone component leaves a silky, non-greasy finish on skin and hair, reducing the need for additional moisturizing ingredients.
Cons and cautions
Silicone content
Some users prefer to avoid silicones due to concerns about buildup or environmental persistence, though this ingredient is water-soluble and rinses away easily.
PEG-related concerns
PEG compounds can be contaminated with ethylene oxide or 1,4-dioxane during manufacturing, but reputable brands ensure purification to safe levels.
Best for
- People with dry or sensitive skin who want a gentle cleanser
- Anyone looking for a makeup remover that rinses cleanly without residue
Use caution if
- Those who strictly avoid silicones in their skincare routine
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. The PEG component is purified in quality manufacturing to minimize impurities. Low irritation and comedogenic risk make it suitable for most skin types.
Research notes
Limited peer-reviewed studies specifically on this compound, but its components (dimethicone, PEG, methyltaurate) are well-studied and generally recognized as safe in cosmetics. The Cosmetic Ingredient Review (CIR) has reviewed similar silicone surfactants and found them safe as used.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The EU CosIng database lists it as a surfactant and emulsifier with no specific restrictions at typical use levels.
- Common uses
- Shampoos, Body washes, Facial cleansers, Makeup removers
- Environmental note
- As a silicone derivative, it may not be readily biodegradable. However, its water-soluble nature reduces the risk of bioaccumulation compared to non-water-soluble silicones.
Good to know
- This ingredient is water-soluble despite being silicone-based, so it rinses off cleanly without leaving heavy residue.
- It is often used in sulfate-free formulas to provide a mild foaming experience.
