Ingredient review
Polyacrylate Crosspolymer-12
INCI: Polyacrylate Crosspolymer-12
A reliable synthetic thickener that gives products a silky, non-greasy feel with minimal irritation risk.
In plain English
Polyacrylate Crosspolymer-12 is a synthetic ingredient used to thicken and stabilize water-based formulas. It creates a smooth, lightweight gel texture that spreads easily and feels silky on the skin, without leaving a heavy or sticky residue. Think of it as a helper that keeps the product consistent and pleasant to use.

Quick decision guide
Useful, but context matters
Polyacrylate Crosspolymer-12 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-12.
- 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 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 designed to absorb and hold water, creating a gel-like consistency.
How it works
When added to water, the polymer chains swell and form a three-dimensional network that traps water molecules. This increases the viscosity of the formula, turning a watery liquid into a smooth gel. It also helps suspend other ingredients (like powders or oils) evenly throughout the product and can form a thin, flexible film on the skin that reduces water loss.
Pros
Lightweight feel
Creates a silky, non-greasy texture that absorbs quickly, making it ideal for gel creams and serums used under makeup or sunscreen.
Low irritation potential
Rarely causes stinging or redness, even on sensitive skin, because it stays on the surface and does not penetrate deeply.
Cons and cautions
Synthetic origin
Made from petroleum-derived acrylic acid, which may not align with natural or clean beauty preferences.
Can feel tacky
If the concentration is too high or combined with certain other thickeners, the product may feel slightly sticky or pill upon application.
Best for
- Anyone who prefers lightweight, gel-based moisturizers or serums
- People with oily or combination skin looking for a matte finish
Use caution if
- Those who strictly avoid synthetic ingredients in their routine
Usage tips
Safety summary
Polyacrylate Crosspolymer-12 has a strong safety profile with very low irritation and sensitization potential. It is considered safe for use in leave-on and rinse-off cosmetics at typical concentrations.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that polyacrylate crosspolymers are safe in cosmetics. Studies show minimal skin penetration and no significant toxicity.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU (CosIng), and many other regions. No concentration restrictions are specified for leave-on products.
- Common uses
- Gel moisturizers, Serums, Sunscreens, Makeup primers
- Environmental note
- As a synthetic polymer, it is not biodegradable. However, it is used in very small amounts and is not known to accumulate in the environment.
Good to know
- Polyacrylate Crosspolymer-12 is often used in 'water cream' textures that feel like they melt into the skin.
- It is considered safe by major regulatory bodies when used within typical concentrations.
