Ingredient review
Polyacrylate Crosspolymer-10
INCI: Polyacrylate Crosspolymer-10
A reliable synthetic thickener that gives products a silky, non-greasy feel without clogging pores or causing irritation.
In plain English
This is a man-made ingredient that helps skincare products feel smooth and lightweight. It works by absorbing water and swelling into tiny gel particles, which thickens the formula and keeps other ingredients evenly mixed. You'll find it in gel-based moisturizers, serums, and sunscreens where it creates a pleasant, non-sticky texture.

Quick decision guide
Useful, but context matters
Polyacrylate Crosspolymer-10 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 Polyacrylate Crosspolymer-10.
- 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 polymer (a large molecule made of repeating units) that is crosslinked to form a three-dimensional network. It is produced through chemical polymerization and is widely used in cosmetics as a rheology modifier.
How it works
When added to water, the polymer particles swell and form a gel-like network. This increases the viscosity of the product, helping it spread smoothly and stay in place on the skin. It also helps stabilize emulsions by preventing oil and water from separating.
Pros
Lightweight texture
Polyacrylate Crosspolymer-10 creates a silky, non-greasy feel that absorbs quickly, making it ideal for gel creams and serums used in humid climates or on oily skin.
Low irritation potential
This ingredient is generally well-tolerated and rarely causes stinging or redness, even on sensitive skin, because it stays on the surface and doesn't penetrate deeply.
Cons and cautions
Synthetic origin
As a man-made polymer, it may not appeal to consumers seeking natural or organic skincare. However, it is not known to be harmful or accumulate in the body.
Possible residue
In high concentrations or with certain other ingredients, it can leave a slight film or tacky feel on the skin, which some users find unpleasant.
Best for
- Anyone who prefers lightweight, gel-based textures
- People with oily or combination skin looking for non-greasy hydration
Use caution if
- Those who strictly avoid synthetic ingredients in their skincare
Usage tips
Safety summary
Polyacrylate Crosspolymer-10 is considered safe for topical use in cosmetics. It has low irritation and comedogenic potential, and no significant systemic absorption. It is not a known allergen or sensitizer.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) and other bodies have concluded that polyacrylate crosspolymers are safe in cosmetic formulations at typical use levels. No significant human or environmental toxicity has been reported.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has evaluated similar polyacrylate crosspolymers and found them safe as used.
- Common uses
- Gels, Serums, Moisturizers, Sunscreens, Makeup
- Environmental note
- As a synthetic polymer, it is not biodegradable. However, it is used in small amounts and is not known to bioaccumulate. Some manufacturers are exploring bio-based alternatives.
Good to know
- Polyacrylate Crosspolymer-10 is often used in 'waterless' or anhydrous gel formulas because it can thicken oils and silicones as well.
- It is considered safe by major regulatory bodies when used within typical cosmetic concentrations.
