Ingredient review
Dimethicone/PEG-3/PPG-15 Crosspolymer
INCI: DIMETHICONE/PEG-3/PPG-15 CROSSPOLYMER
A gentle silicone polymer that improves product feel and wear without clogging pores or irritating skin.
In plain English
This is a silicone ingredient that forms a thin, breathable film on your skin. It helps creams and serums glide on smoothly, reduces that sticky or tacky feeling, and can make makeup last longer. Think of it like a very lightweight, invisible glove that doesn't trap oil or sweat.

Quick decision guide
Useful, but context matters
Dimethicone/PEG-3/PPG-15 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/PEG-3/PPG-15 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 created by crosslinking dimethicone with PEG and PPG chains. It is a modified silicone designed to be more compatible with water-based formulas while retaining silicone's silky feel.
How it works
When applied, it spreads into an even, flexible film that sits on the skin's surface. This film smooths out fine lines temporarily, helps other ingredients stay put, and reduces water loss from the skin without feeling heavy or greasy.
Pros
Smooth, silky finish
Leaves skin feeling velvety and soft without a greasy residue, making it ideal for primers and daytime moisturizers.
Improves product stability
Helps keep emulsions from separating and gives a consistent texture from first use to last.
Cons and cautions
Silicone-based
Some people choose to avoid silicones due to personal preference or concerns about environmental persistence, though this ingredient is generally considered safe.
Can feel heavy in high amounts
In very concentrated formulas, it may leave a slightly thick or coating sensation that some find uncomfortable.
Best for
- Anyone who wants a smoother, more elegant texture in their skincare
- People with normal to combination skin looking for a lightweight moisturizing feel
Use caution if
- Those who prefer silicone-free routines for personal or environmental reasons
Usage tips
Safety summary
Considered safe for topical use in cosmetics. It has a low irritation and comedogenic profile, making it suitable for most skin types including sensitive and acne-prone skin.
Research notes
Silicone crosspolymers are well-studied for their film-forming and sensory properties. Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that dimethicone crosspolymers are safe as used in cosmetics.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the FDA (US) and EU CosIng database, with no known restrictions at typical use levels.
- Common uses
- Moisturizers, Serums, Sunscreens, Primers, Color Cosmetics
- Environmental note
- As a silicone derivative, it may be persistent in the environment. However, crosspolymer forms are larger molecules that are less likely to be absorbed or bioaccumulate compared to some cyclic silicones.
Good to know
- This crosspolymer is more water-friendly than plain dimethicone, so it works well in gel-creams and lightweight lotions.
- It is often used in 'invisible' sunscreens to improve texture and reduce white cast.
