Polyacrylamide

INCI: POLYACRYLAMIDE

Polyacrylamide is a safe, effective thickener that gives products a smooth, silky feel, but it's often paired with preservatives that raise concerns for some users.

In plain English

Polyacrylamide is a synthetic ingredient that helps thicken and stabilize lotions, creams, and serums. Think of it like a thickening agent that gives your moisturizer a nice, spreadable texture and prevents it from separating into water and oil. It's widely used because it's gentle on skin and creates a smooth, non-greasy feel. However, it's often combined with other ingredients (like C13-14 Isoparaffin and Laureth-7) that help it work, and some people worry about potential impurities from its production process.

Quick decision guide

Useful, but context matters

Polyacrylamide 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 Polyacrylamide.
  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

Polyacrylamide is a synthetic polymer—a long chain of repeating units—made from acrylamide monomers. In cosmetics, it's used as a thickener, stabilizer, and film-forming agent. It's typically supplied as a mixture with other ingredients to improve its performance and safety.

How it works

When added to a water-based formula, polyacrylamide molecules entangle and form a network that increases the product's viscosity (thickness). This helps create a smooth, creamy texture and prevents the product from separating. It also forms a thin, invisible film on the skin that can help other ingredients stay in place and reduce water loss.

Pros

Excellent texture enhancer

Polyacrylamide gives creams and serums a silky, non-sticky feel that spreads easily and absorbs quickly, improving the user experience.

Low irritation potential

It is generally well-tolerated by most skin types, including sensitive skin, and has a low risk of causing breakouts or irritation.

Cons and cautions

Potential impurity concerns

If not highly purified, polyacrylamide can contain residual acrylamide monomer, which is a neurotoxin. However, cosmetic-grade polyacrylamide is strictly regulated to ensure very low levels.

Not biodegradable

As a synthetic polymer, polyacrylamide does not break down easily in the environment, which may be a concern for eco-conscious consumers.

Best for

  • People who enjoy lightweight, non-greasy moisturizers
  • Those with normal to oily skin looking for a smooth finish

Use caution if

  • Individuals with known sensitivity to synthetic polymers or very sensitive skin (rare)
  • Those seeking 100% natural or biodegradable formulations

Usage tips

Use products containing polyacrylamide as directed; it is already formulated at safe concentrations.
If you have very sensitive skin, patch test a new product containing polyacrylamide before full use.
Store products in a cool, dry place to maintain stability.

Safety summary

Polyacrylamide is considered safe for use in cosmetics when properly purified. Regulatory bodies set strict limits on residual acrylamide monomer to protect consumers. It has a low risk of irritation or comedogenicity.

Research notes

Studies confirm that cosmetic-grade polyacrylamide is safe at typical use levels. The main safety concern is residual acrylamide, but industry standards and regulations keep levels well below harmful thresholds.

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, with limits on residual acrylamide monomer.
Common uses
Moisturizers, Serums, Sunscreens, Makeup
Environmental note
Polyacrylamide is not biodegradable and can persist in water systems, though it is used in very small amounts in cosmetics.

Good to know

  • Polyacrylamide is often listed in ingredient lists alongside C13-14 Isoparaffin and Laureth-7, which help it disperse and stabilize the formula.
  • The cosmetic industry has strict purity standards to keep acrylamide monomer levels below 0.1 ppm (parts per million).
