Acrylamides/Dmapa Acrylates/Methoxy Peg Methacrylate Copolymer

INCI: ACRYLAMIDES/DMAPA ACRYLATES/METHOXY PEG METHACRYLATE COPOLYMER

A synthetic polymer that helps products stay put, but offers no active skincare benefit.

beautyskincarehaircare

In plain English

This is a man-made ingredient that forms a thin, flexible film on your skin or hair. It helps makeup last longer, makes sunscreen more water-resistant, and gives hair products hold. Think of it like a clear, invisible layer that helps the product stay where you put it.

Quick decision guide

Useful, but context matters

Acrylamides/Dmapa Acrylates/Methoxy Peg Methacrylate 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 Acrylamides/Dmapa Acrylates/Methoxy Peg Methacrylate 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 synthetic copolymer—a large molecule made by linking smaller chemical units (acrylamide, DMAPA acrylates, and methoxy PEG methacrylate). It is designed to create a flexible, water-resistant film.

How it works

When applied, the copolymer molecules spread out and link together as the water or solvent evaporates, forming a continuous film. This film physically blocks water and sweat, helps pigments adhere, and increases the viscosity (thickness) of the product for better application.

Pros

Boosts product longevity

Helps makeup and sunscreen resist sweat, water, and rubbing, so you don't have to reapply as often.

Improves texture and feel

Creates a smooth, even application and can make products feel less greasy by forming a dry film.

Cons and cautions

Synthetic and non-biodegradable

Made from petroleum-derived chemicals, which may be a concern for eco-conscious users.

Potential for tackiness

In high concentrations or certain formulations, it can leave a slightly sticky or stiff feeling on skin or hair.

Best for

  • Anyone wanting long-wearing makeup or water-resistant sunscreen
  • People with normal to oily skin who need products to stay put

Use caution if

  • Those who prefer exclusively natural or plant-based ingredients
  • Individuals with very sensitive skin who react to film-forming polymers

Usage tips

Use a gentle oil-based cleanser or micellar water to fully remove products containing this polymer.
If you find a product too tacky, try applying a lighter layer or setting with powder.

Safety summary

Generally recognized as safe for topical cosmetic use at typical concentrations. Low irritation and comedogenic potential. No significant safety concerns reported in available literature.

Research notes

Limited peer-reviewed studies specifically on this copolymer, but it is part of a well-studied class of acrylate polymers. Safety assessments by industry panels (e.g., CIR) have found similar acrylate copolymers safe for cosmetic use.

Common label clues

Typical concentration
0.5% to 5%
Regulatory status
Approved for use in cosmetics in the US (FDA), EU (CosIng), and other major markets. No specific restrictions at typical use levels.
Common uses
Sunscreens, Mascaras, Eyeliners, Long-wear foundations, Hair styling products
Environmental note
As a synthetic polymer, it is not biodegradable and may contribute to microplastic pollution. However, it is used in small amounts and is often removed during wastewater treatment.

Good to know

  • This ingredient is often used in combination with other film-formers to fine-tune the feel and durability of a product.
  • It is considered safe for use in cosmetics by major regulatory bodies at typical concentrations.
