Ingredient review
PEG/PPG-12/16 Dimethicone
INCI: PEG/PPG-12/16 Dimethicone
A gentle silicone emulsifier that improves texture and helps ingredients mix, but may not suit those avoiding silicones.
In plain English
PEG/PPG-12/16 Dimethicone is a modified silicone ingredient that acts like a bridge between water and oil in a formula. It helps create smooth, spreadable creams and lotions without feeling greasy. The 'PEG/PPG' part means it has been made water-friendly, so it can work in both water-based and oil-based products. It also leaves a silky, non-sticky feel on the skin.

Quick decision guide
Useful, but context matters
PEG/PPG-12/16 Dimethicone 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 PEG/PPG-12/16 Dimethicone.
- 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 silicone polymer that has been chemically modified with polyethylene glycol (PEG) and polypropylene glycol (PPG) chains to make it water-dispersible. It is a clear to slightly hazy liquid used to stabilize emulsions and improve product feel.
How it works
It sits at the boundary between water and oil droplets in a formula, reducing surface tension so they mix into a stable cream or lotion. On skin, it forms a thin, breathable film that smooths the surface and reduces water loss without clogging pores.
Pros
Smooth texture
Creates a silky, spreadable feel in creams and lotions, making application pleasant and even.
Gentle on skin
Low irritation and comedogenic risk, suitable for most skin types including sensitive skin.
Cons and cautions
Silicone concerns
Some people avoid silicones due to personal preference or concerns about environmental persistence.
Potential buildup
With frequent use and inadequate cleansing, it may accumulate on skin or hair, leading to dullness.
Best for
- People who want lightweight, non-greasy moisturizers
- Those with normal to combination skin looking for smooth makeup or skincare texture
Use caution if
- Individuals who prefer silicone-free or PEG-free formulations
Usage tips
Safety summary
PEG/PPG-12/16 Dimethicone has a low irritation and comedogenic risk and is considered safe in cosmetic formulations at typical concentrations. However, individuals with very sensitive skin or those avoiding silicones may prefer alternatives.
Research notes
Research indicates that PEG-modified silicones are effective emulsifiers with low skin irritation potential. Their safety has been reviewed by the Cosmetic Ingredient Review (CIR) panel, which found them safe for use in cosmetics.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions, subject to concentration limits for PEG compounds.
- Common uses
- Moisturizers, Serums, Sunscreens, Foundations, Primers
- Environmental note
- Silicones like dimethicone are not readily biodegradable and may accumulate in the environment; some consumers choose alternatives for this reason.
Good to know
- PEG/PPG-12/16 Dimethicone is considered safe by cosmetic safety panels at typical use levels
- It is often used in 'silicone blend' emulsifiers to improve formula stability
