Ingredient review
Polyacrylate
INCI: Polyacrylate
Polyacrylate is a safe, widely used synthetic thickener that gives products a smooth, gel-like texture without clogging pores.
In plain English
Polyacrylate is a man-made ingredient that helps skincare products feel smooth and spread easily. It acts like a sponge, soaking up water to create a gel or cream texture. You'll find it in many lotions, sunscreens, and serums to keep the formula stable and pleasant to use. It sits on the surface of your skin and doesn't absorb deeply, so it's generally non-irritating and non-comedogenic (won't clog pores).

Quick decision guide
Useful, but context matters
Polyacrylate 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.
- 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 is a synthetic polymer—a long chain of repeating molecules—designed to thicken water-based formulas. It is often used in combination with other ingredients to create a lightweight, non-greasy feel.
How it works
When mixed with water, polyacrylate molecules swell and form a network that traps water, increasing the viscosity of the product. This gives a smooth, gel-like consistency. It also helps suspend other ingredients (like oils or powders) and can form a thin, flexible film on the skin that improves wear or water resistance.
Pros
Lightweight texture
Polyacrylate creates a silky, non-greasy feel that absorbs quickly, making it ideal for gel creams and serums used under makeup or sunscreen.
Stable formulations
It helps keep ingredients evenly mixed and prevents separation, so your product stays effective and looks consistent from first use to last.
Cons and cautions
Synthetic origin
Polyacrylate is made from petroleum-derived materials, which may be a concern if you prefer plant-based or naturally derived ingredients.
Potential tackiness
In high concentrations or with certain formulas, polyacrylate can leave a slightly sticky or tacky residue on the skin, especially in humid conditions.
Best for
- Anyone who enjoys lightweight, gel-based moisturizers or serums
- People with oily or combination skin looking for non-greasy textures
Use caution if
- Those who prefer only natural or plant-derived thickeners
- Individuals with very sensitive skin who react to many synthetic polymers (rare)
Usage tips
Safety summary
Polyacrylate is considered safe for topical use in cosmetics. It has low irritation and comedogenic potential, and is not known to be toxic or allergenic at typical concentrations. However, as a synthetic polymer, it may not be suitable for those seeking fully natural formulations.
Research notes
Research on polyacrylate focuses on its function as a thickener and stabilizer. Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded it is safe for use in cosmetics when formulated properly. No significant human health risks have been identified.
Common label clues
- Typical concentration
- 0.1% to 5%
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission, with no known restrictions at typical levels.
- Common uses
- Gels, Creams, Serums, Sunscreens
- Environmental note
- Polyacrylate is not biodegradable and may persist in the environment, though it is used in very small amounts per product.
Good to know
- Polyacrylate is often listed as 'Polyacrylate Crosspolymer' or 'Polyacrylate-13' on ingredient labels.
- It is considered safe by major regulatory bodies when used within typical concentrations.
