Quick decision guide

Useful, but context matters

Polyacrylate Crosspolymer-7 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Polyacrylate Crosspolymer-7.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A synthetic polymer made from acrylic acid monomers that are crosslinked to form a network structure. It is produced through controlled chemical reactions and is widely used in cosmetics for its ability to thicken and stabilize formulas.

How it works

When added to water, the polymer chains swell and form a gel-like network, increasing the viscosity of the product. This helps suspend other ingredients, prevent separation, and create a smooth, non-sticky feel on the skin. It also forms a thin, flexible film that can help lock in moisture.

Pros

Smooth texture

Creates a silky, non-greasy feel that makes products pleasant to apply and wear.

Low irritation risk

Rarely causes skin reactions, making it suitable for sensitive skin types.

Cons and cautions

Synthetic origin

Derived from petroleum-based chemicals, which may not align with natural skincare preferences.

Potential tackiness

In high concentrations, it can leave a slightly sticky or tacky residue on the skin.

Best for

  • Anyone looking for a lightweight, non-greasy moisturizer texture
  • People with oily or combination skin who prefer matte finishes

Use caution if

  • Those seeking 100% natural or organic formulations

Usage tips

Use products with this ingredient after water-based serums for best layering.
Apply to damp skin to help the film spread evenly and reduce any tackiness.
