INCI: Polyacrylate Crosspolymer-5

A safe, synthetic thickener that gives skincare products a silky, lightweight feel without clogging pores.

In plain English

Polyacrylate Crosspolymer-5 is a man-made ingredient that helps skincare products feel smooth and lightweight. It acts like a sponge that soaks up water and turns into a clear gel, so your moisturizer or serum spreads easily and doesn't feel sticky or greasy. It also helps keep the product from separating into oil and water layers.

Quick decision guide

Useful, but context matters

Polyacrylate Crosspolymer-5 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-5.
  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 that is crosslinked to form a network structure. It is produced in a lab and is not found in nature.

How it works

When added to water, the polymer particles swell and form a gel-like network. This thickens the product, stabilizes emulsions (mixes of oil and water), and creates a smooth, non-tacky feel on the skin. It also helps other ingredients spread evenly.

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.

Stabilizes formulas

Helps keep oil and water mixed together, preventing separation and extending the shelf life of your products.

Cons and cautions

Synthetic origin

Made in a lab from acrylic acid, which may not appeal to people seeking 100% natural or organic skincare.

Potential pilling

If layered with certain silicones or oils, the polymer can ball up into small flakes on the skin, which can be annoying.

Best for

  • Anyone who prefers lightweight, gel-based moisturizers or serums
  • People with oily or combination skin who want a matte finish

Use caution if

  • Those who strictly avoid synthetic ingredients in their routine

Usage tips

Apply gel-based products containing this ingredient to damp skin for better spreadability.
Avoid rubbing too vigorously when layering with silicone-heavy primers to reduce pilling.

Safety summary

Polyacrylate Crosspolymer-5 is considered safe for use in cosmetics. It has low irritation and comedogenic potential, and no significant toxicity concerns have been identified at typical concentrations.

Research notes

Safety assessments by cosmetic ingredient review panels have concluded that polyacrylate crosspolymers are safe when formulated properly. Most evidence comes from industry safety data rather than independent clinical studies.

Common label clues

Typical concentration
0.1% to 2%
Regulatory status
Approved for use in cosmetics in the US, EU, and other major markets. No known restrictions at typical use levels.
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 considered a major environmental concern compared to microplastics.

Good to know

  • Polyacrylate Crosspolymer-5 is often used in 'water cream' textures that feel like water on the skin.
  • It is considered safe by major regulatory bodies and is not known to be a common allergen.
