Ingredient review
PEG-10 Dimethicone Crosspolymer
INCI: PEG-10 Dimethicone Crosspolymer
A silicone polymer that gives products a silky, smooth feel and helps stabilize formulas without clogging pores.
In plain English
This is a synthetic silicone ingredient that acts like a sponge to thicken and stabilize lotions, creams, and makeup. It creates a lightweight, silky film on the skin that helps other ingredients spread evenly and feel smooth. It is not absorbed into the skin and sits on the surface, which can help reduce water loss without feeling heavy or greasy.

Quick decision guide
Useful, but context matters
PEG-10 Dimethicone 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 PEG-10 Dimethicone 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 crosslinked silicone polymer made by reacting PEG-10 dimethicone with a crosslinking agent. It forms a three-dimensional network that can absorb and hold oils and silicones, turning them into a gel-like texture.
How it works
When mixed into a formula, the crosspolymer swells and creates a gel network that thickens the product and prevents oil and water from separating. On the skin, it leaves a thin, breathable film that feels silky and helps other ingredients stay in place.
Pros
Silky texture
Creates a smooth, velvety feel on skin that makes products glide on easily and reduces drag during application.
Stabilizes formulas
Helps keep oil and water mixed together, so your lotion or cream stays consistent and doesn't separate over time.
Cons and cautions
Synthetic origin
Made from petrochemicals, which may be a concern if you prefer only natural or plant-based ingredients.
Surface-only action
Sits on top of the skin and does not provide active skincare benefits like hydration or antioxidants.
Best for
- People who want a smooth, velvety finish in moisturizers or primers
- Those with oily or combination skin who prefer lightweight textures
Use caution if
- Anyone strictly avoiding all silicones for personal preference
- Those with known sensitivity to PEG compounds (rare)
Usage tips
Safety summary
PEG-10 Dimethicone Crosspolymer is considered safe for topical use. It is not absorbed into the skin, has low irritation potential, and is non-comedogenic. The PEG component is generally safe at the low levels used in cosmetics.
Research notes
Safety assessments by the Cosmetic Ingredient Review panel and other bodies have concluded that dimethicone crosspolymers are safe in cosmetics. Studies focus on their physical properties rather than biological activity, as they are inert on the skin.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and other major markets. The Cosmetic Ingredient Review (CIR) panel has reviewed similar silicone crosspolymers and found them safe as used.
- Common uses
- Moisturizers, Serums, Sunscreens, Foundations, Primers
- Environmental note
- Silicones like this are not biodegradable and can accumulate in the environment. Some manufacturers are moving toward biodegradable alternatives.
Good to know
- PEG-10 Dimethicone Crosspolymer is considered non-comedogenic and safe for most skin types.
- It is often used in 'silicone gel' textures that feel like a soft, bouncy solid.
