Ingredient review
Polyacrylate-2 Crosspolymer
INCI: Polyacrylate-2 Crosspolymer
A safe, synthetic thickener and stabilizer that gives products a smooth, lightweight feel without clogging pores.
In plain English
This is a synthetic ingredient that helps skincare products have the right texture—think of it like a thickening agent that turns a watery liquid into a nice gel or creamy lotion. It also helps keep the product stable so the oil and water parts don't separate. It sits on top of your skin and doesn't get absorbed, so it's generally non-irritating and won't clog pores.

Quick decision guide
Useful, but context matters
Polyacrylate-2 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 Polyacrylate-2 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
Polyacrylate-2 Crosspolymer is a high-molecular-weight synthetic polymer made from acrylic acid monomers that are crosslinked to form a network structure. It is produced through controlled polymerization and is used primarily as a rheology modifier and stabilizer in cosmetic formulations.
How it works
When added to water, the polymer chains swell and form a three-dimensional network that increases the viscosity of the formula. This network also helps suspend insoluble particles and stabilize emulsions by preventing oil and water from separating. On the skin, it dries down to a flexible, non-sticky film that can improve the wear of makeup or sunscreen.
Pros
Lightweight texture
Creates a smooth, silky feel on the skin without heaviness or greasiness, making it ideal for gel-based moisturizers and serums.
Excellent stabilizer
Helps keep oil and water mixed together, so your product stays consistent and effective from first use to last.
Cons and cautions
Synthetic origin
Derived from petroleum-based acrylic acid, which may be a concern for those seeking fully natural or biodegradable ingredients.
Potential tackiness
In some formulations, especially at higher concentrations, it can leave a slightly sticky or tacky residue on the skin.
Best for
- Anyone who enjoys lightweight gel or cream textures
- People with oily or combination skin looking for non-greasy formulas
Use caution if
- Those who strictly avoid all synthetic ingredients
- Individuals with known sensitivity to acrylate polymers (rare)
Usage tips
Safety summary
Polyacrylate-2 Crosspolymer is considered safe for topical use in cosmetics. It has low irritation and comedogenic potential, and no significant systemic absorption occurs because the molecule is too large to penetrate the skin.
Research notes
Safety assessments by expert panels (e.g., CIR) have reviewed similar acrylate crosspolymers and found them safe at typical use levels. Specific studies on Polyacrylate-2 Crosspolymer are limited, but its chemical class is well-characterized and widely used.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for use in cosmetics globally, including by the U.S. FDA and EU CosIng database, with no concentration restrictions.
- Common uses
- Gels, Creams, Serums, Sunscreens, Makeup
- Environmental note
- As a synthetic polymer, it is not biodegradable and may contribute to microplastic concerns if not properly filtered during wastewater treatment.
Good to know
- Polyacrylate-2 Crosspolymer is different from polyacrylamide, which has more safety scrutiny.
- It is often used in 'gel-cream' formulas that feel refreshing and absorb quickly.
