PEG/PPG-25/25 Dimethicone/Acrylates Copolymer

INCI: PEG/PPG-25/25 Dimethicone/Acrylates Copolymer

A versatile film-forming silicone that helps makeup and sunscreen stay put without feeling heavy.

beautyskincarefilm-former

In plain English

This is a synthetic ingredient that combines silicone and acrylic polymers. When applied to skin, it dries down to form a flexible, breathable film that helps other ingredients (like pigments or UV filters) stay in place longer. It also helps products resist water and sweat, which is why it's common in long-wear makeup and sunscreens. Despite its long chemical name, it's generally well-tolerated and not known to clog pores.

Quick decision guide

Useful, but context matters

PEG/PPG-25/25 Dimethicone/Acrylates Copolymer 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/PPG-25/25 Dimethicone/Acrylates Copolymer.
  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 hybrid copolymer made by attaching silicone chains (dimethicone) to acrylic polymer backbones, with PEG and PPG groups to improve water dispersibility.

How it works

When the water or solvent in a product evaporates, the copolymer molecules link together to form a thin, flexible film on the skin. This film locks in pigments and active ingredients, while the silicone portion gives a smooth, silky feel and helps the film resist water and oil.

Pros

Boosts wear time

Creates a flexible film that helps makeup and sunscreen stay intact for hours, even in humid or sweaty conditions.

Lightweight feel

Despite being a film-former, it dries to a silky, non-sticky finish that doesn't feel heavy or tight on the skin.

Cons and cautions

Requires thorough removal

The film can be stubborn and may not wash off with a gentle cleanser alone, often needing an oil-based cleanser or micellar water.

Potential for buildup

If not fully removed, residue can accumulate over time, potentially leading to dullness or clogged pores for some skin types.

Best for

  • Anyone looking for long-wearing makeup or water-resistant sunscreen
  • People with oily or combination skin who want a matte, stay-put finish

Use caution if

  • Those who prefer minimal, easily removable products and dislike double cleansing

Usage tips

Use an oil-based cleanser or micellar water first to break down the film, then follow with your regular water-based cleanser.
In sunscreens, apply evenly and allow to dry for a minute before makeup to ensure a uniform film.

Safety summary

Generally considered safe for most skin types. The PEG components are ethoxylated, which can sometimes contain trace impurities, but cosmetic-grade ingredients are purified. The film-forming nature is well-tolerated, though individuals with very sensitive skin should patch test.

Research notes

The Cosmetic Ingredient Review (CIR) panel has evaluated similar PEG/PPG dimethicone acrylates copolymers and found them safe in cosmetic formulations. No significant human or animal toxicity concerns have been reported at typical use levels.

Common label clues

Typical concentration
0.5% to 5% in most formulas
Regulatory status
Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has reviewed it and found it safe as used.
Common uses
Sunscreens, Long-wear foundations, Waterproof mascaras, Primers
Environmental note
As a synthetic silicone-based polymer, it is not biodegradable and may persist in the environment. However, it is used in low concentrations.
