Ingredient review
Dimethicone/PPG-20 Crosspolymer
INCI: DIMETHICONE/PPG-20 CROSSPOLYMER
A silicone polymer that creates a smooth, breathable film on skin, improving product feel and longevity without clogging pores.
In plain English
This is a silicone-based ingredient that forms a thin, flexible film on your skin. It helps makeup and skincare products glide on smoothly, feel silky, and stay in place longer. Unlike some heavy silicones, this crosspolymer version is designed to be lightweight and non-greasy, so it won't feel heavy or sticky. It's often used in primers and sunscreens to improve texture and wear.

Quick decision guide
Useful, but context matters
Dimethicone/PPG-20 Crosspolymer 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 Dimethicone/PPG-20 Crosspolymer.
- 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 silicone polymer made by crosslinking dimethicone (a common silicone) with PPG-20 (a polypropylene glycol derivative). This creates a larger, more structured molecule that forms a breathable film on the skin.
How it works
When applied, it spreads into a thin, even layer that fills in fine lines and pores, creating a smooth surface. The film is flexible and water-resistant, helping other ingredients stay in place and reducing the need for reapplication. It also gives products a silky, velvety feel without leaving a greasy residue.
Pros
Smooth, silky feel
Creates a velvety, non-greasy texture that makes products feel luxurious and helps makeup glide on effortlessly.
Improves wear time
Forms a flexible, water-resistant film that helps makeup and sunscreen stay in place longer, reducing the need for touch-ups.
Cons and cautions
Silicone-based
If you prefer to avoid silicones in your routine, this ingredient won't fit your preferences, though it is generally considered safe.
Can be tricky to remove
Because it forms a film, it may require a double cleanse (oil-based cleanser followed by water-based) to fully remove, especially if layered.
Best for
- People who want a smooth, poreless look under makeup
- Those with oily or combination skin looking for a matte finish
Use caution if
- Individuals who prefer silicone-free skincare routines
Usage tips
Safety summary
Dimethicone/PPG-20 Crosspolymer is considered safe for use in cosmetics. It has low irritation and comedogenic potential, and is well-tolerated by most skin types. As with all silicones, it is not biodegradable, which is an environmental consideration.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that dimethicone and related crosspolymers are safe for use in cosmetics at current levels. Research focuses on sensory and film-forming properties rather than biological activity.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics globally, including by the FDA and EU CosIng database, with no known restrictions at typical concentrations.
- Common uses
- Primers, Sunscreens, Moisturizers, Color Cosmetics
- Environmental note
- Silicones like this one are synthetic and not biodegradable, which raises concerns about accumulation in the environment. However, crosspolymer forms may be less mobile than linear silicones.
Good to know
- This ingredient is often found in 'pore-filling' primers and long-wear foundations.
- It is considered non-comedogenic and safe for most skin types.
