Acrylates Copolymer Blend

INCI: DIMETHYLAMINOETHYLMETHACRYLATE/HEMA/LAURYL METHACRYLATE COPOLYMER

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

beautyskincarefilm-former

In plain English

This is a plastic-like ingredient that forms a thin, flexible film on your skin or hair. It's added to help makeup last longer, make sunscreen more water-resistant, or give hair products better hold. Think of it as a clear, invisible coating that helps other ingredients stay in place.

Quick decision guide

Useful, but context matters

Acrylates Copolymer Blend 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 Acrylates Copolymer Blend.
  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 made from three monomers: dimethylaminoethyl methacrylate, hydroxyethyl methacrylate, and lauryl methacrylate. It's engineered to create a flexible, water-resistant film when applied to skin or hair.

How it works

When the water or solvent in a product evaporates, the copolymer molecules link together into a continuous, invisible film. This film physically blocks water from reaching the underlying ingredients (like sunscreen filters) and helps pigments or active ingredients stay put on the skin or hair surface.

Pros

Boosts water resistance

Helps sunscreens and makeup stay effective longer when you sweat or swim, reducing the need for frequent reapplication.

Improves wear time

Creates a flexible film that keeps foundation, mascara, or eyeliner from smudging or fading throughout the day.

Cons and cautions

No skincare benefit

This ingredient is purely functional—it doesn't hydrate, soothe, or treat the skin. It's only there to improve product performance.

Can feel tight

In high concentrations, the film can make skin feel slightly stiff or taut, which may be uncomfortable for some users.

Best for

  • Anyone wanting longer-lasting makeup or water-resistant sunscreen
  • People with normal to oily skin who prefer matte, long-wear formulas

Use caution if

  • Those with very dry or sensitive skin who find film-formers tight or uncomfortable

Usage tips

Use a gentle oil-based cleanser or micellar water to fully remove products containing this film-former at the end of the day.
If you find the feel too tight, look for formulas where this ingredient appears lower on the ingredient list (indicating a lower concentration).

Safety summary

This copolymer is considered safe for topical use at typical concentrations. It has a low irritation and comedogenic risk. No significant safety concerns have been identified in cosmetic applications.

Research notes

Safety assessments rely on the established safety of similar acrylate copolymers used in cosmetics. No specific human clinical trials on this exact copolymer were found, but the ingredient class is well-studied and considered safe.

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 concentration restrictions are typically imposed for leave-on or rinse-off products.
Common uses
Sunscreens, Waterproof mascaras, Long-wear foundations, Hair styling products
Environmental note
As a synthetic polymer, it is not biodegradable. However, it is used in small amounts and is not known to bioaccumulate significantly.

Good to know

  • This copolymer is often used alongside other film-formers to fine-tune the flexibility and water resistance of a product.
  • It is considered safe for use in cosmetics by major regulatory bodies when used as directed.
