Acrylates/Carbamate Copolymer

INCI: ACRYLATES/CARBAMATE COPOLYMER

A synthetic polymer that helps products stay put and resist water, but offers no direct skin benefit.

beautyskincarefilm-former

In plain English

This ingredient is a type of plastic-like polymer that forms a thin, flexible film on your skin. It's added to products like sunscreen or long-wear makeup to help them stay in place longer and resist water or sweat. Think of it like a clear, invisible shield that holds the product on your skin. It doesn't moisturize or treat your skin—it's purely a texture and performance helper.

Quick decision guide

Useful, but context matters

Acrylates/Carbamate 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 Acrylates/Carbamate 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 made from acrylic acid derivatives and carbamate compounds, designed to create a flexible film on the skin.

How it works

When applied, the polymer chains spread out and then dry into a continuous, flexible film. This film physically locks in other ingredients (like sunscreen filters or pigments) and creates a barrier that resists water and friction.

Pros

Boosts product longevity

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

Improves texture

Creates a smooth, even film that can make skin feel silky and help makeup glide on evenly.

Cons and cautions

No active skincare benefit

This ingredient is purely functional—it doesn't hydrate, soothe, or treat any skin concerns.

Potential tightness

On very dry or sensitive skin, the film can feel slightly tight or uncomfortable, especially if layered heavily.

Best for

  • Anyone wanting long-wear makeup or water-resistant sunscreen
  • People with oily skin who prefer matte, stay-put formulas

Use caution if

  • Those with very dry or compromised skin barriers who may find film-formers too occlusive

Usage tips

Use with a good moisturizer underneath if you have dry skin, to avoid any tight feeling.
Apply sunscreen or makeup containing this polymer in thin, even layers for best film formation.

Safety summary

Considered safe for topical use at typical concentrations. Low irritation and comedogenic risk. No known toxicity concerns from skin contact. Not intended for ingestion.

Research notes

Limited independent studies on this specific copolymer, but the broader class of acrylate copolymers has a long history of safe use in cosmetics. Safety is supported by industry self-assessments and regulatory approvals.

Common label clues

Typical concentration
0.5% to 5%
Regulatory status
Approved for use in cosmetics globally, including by the FDA (as part of sunscreen formulations) and the EU CosIng database. No known restrictions at typical use levels.
Common uses
Sunscreens, Long-wear makeup, Water-resistant formulas
Environmental note
As a synthetic polymer, it may not be biodegradable. Some manufacturers are exploring bio-based alternatives, but this is not yet common.

Good to know

  • This polymer is often used in 'sport' or 'water-resistant' sunscreens.
  • It is not absorbed into the skin—it stays on the surface.
