Quick decision guide

Useful, but context matters

Acrylamide Crosspolymer Thickener 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 Acrylamide Crosspolymer Thickener.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

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 crosspolymer made from acrylamide monomers and PEG-14 diacrylate, designed to absorb water and swell into a gel-like network.

How it works

When mixed with water, the polymer chains link together to form a three-dimensional network that traps water molecules. This creates a thicker, more viscous product that feels silky on the skin and helps other ingredients spread evenly.

Pros

Smooth texture

Creates a silky, non-sticky feel that makes products pleasant to apply and layer under makeup.

Stable formulas

Helps keep ingredients evenly mixed, so your product stays effective and doesn't separate over time.

Cons and cautions

Synthetic origin

Made from man-made chemicals, which may not align with a natural or clean beauty preference.

No active benefit

Does not hydrate, brighten, or treat skin concerns—it only improves product feel and stability.

Best for

  • Anyone who prefers lightweight, non-greasy moisturizers or serums
  • People with oily or combination skin looking for a matte finish

Use caution if

  • Those strictly avoiding all synthetic ingredients
  • Individuals with known acrylate allergies (rare)

Usage tips

Use products with this ingredient after cleansing and before heavier creams for best layering.
If you have sensitive skin, patch test a new product first, though irritation is rare.

Safety summary

Generally recognized as safe for topical use in cosmetics. Rare allergic reactions are possible, especially for individuals with acrylate sensitivities. No known links to serious health concerns at typical concentrations.

Research notes

Safety data is based on industry reviews and regulatory assessments rather than independent clinical studies. The CIR panel has concluded that similar acrylamide crosspolymers are safe in cosmetic formulations.

Common label clues

Typical concentration
0.1% to 2%
Regulatory status
Approved for use in cosmetics in the US, EU, and other major markets. The Cosmetic Ingredient Review (CIR) panel has reviewed similar acrylamide crosspolymers and found them safe at typical use levels.
Common uses
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.
