INCI: PEG-22 Dimethacrylate

A synthetic film-former that helps products feel smooth and stay put, but offers no active skincare benefit.

In plain English

PEG-22 Dimethacrylate is a man-made ingredient that helps create a thin, flexible film on your skin. It's often used in peel-off masks or water-resistant formulas to give them a smooth, even texture and help them stay in place. Think of it like a clear, invisible layer that helps the product perform better, but it doesn't moisturize or treat your skin on its own.

Quick decision guide

Useful, but context matters

PEG-22 Dimethacrylate 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 PEG-22 Dimethacrylate.
  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 derived from polyethylene glycol and methacrylic acid. It is a clear, viscous liquid that forms a film when applied to the skin.

How it works

When applied, the molecules link together (polymerize) to form a continuous, flexible film on the skin's surface. This film helps other ingredients stay put, improves water resistance, and gives products a smooth, non-sticky feel.

Pros

Improves product feel

Creates a smooth, even application and a non-sticky finish, making products more pleasant to use.

Boosts water resistance

Helps sunscreens and other leave-on products stay effective longer when you sweat or get wet.

Cons and cautions

No active benefit

It only improves texture and water resistance—it doesn't moisturize, soothe, or treat skin conditions.

Can feel tight

In high concentrations, the film it forms may feel tight or slightly drying, especially on already dry skin.

Best for

  • Anyone using peel-off masks or water-resistant sunscreens
  • People who prefer a smooth, non-sticky finish

Use caution if

  • Those with very dry or sensitive skin who may find film-formers tightening

Usage tips

Use peel-off masks containing this ingredient no more than once a week to avoid over-drying.
Always follow with a moisturizer if you feel any tightness after using a product with this ingredient.

Safety summary

PEG-22 Dimethacrylate is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic potential. Some individuals with very sensitive or dry skin may experience mild tightness.

Research notes

Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that PEG dimethacrylates are safe in cosmetic formulations when formulated to be non-irritating. No significant human or animal studies indicate toxicity at typical use levels.

Common label clues

Typical concentration
Typically 1–10% in leave-on products
Regulatory status
Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed similar PEG dimethacrylates and found them safe at typical use levels.
Common uses
Masks, Peel-off masks, Water-resistant formulas
Environmental note
As a synthetic polymer, it is not biodegradable. However, it is used in small amounts and is not known to accumulate in the environment.

Good to know

  • PEG-22 Dimethacrylate is considered safe for use in cosmetics by expert panels when used as directed.
  • It is not a preservative, fragrance, or active treatment ingredient.
