In plain English

This ingredient is a type of plastic-like material that forms a thin, flexible film on your skin. It's added to products like sunscreen and long-wear makeup to help them stay in place longer and resist water or sweat. Think of it as a gentle glue that holds the product on your skin without feeling heavy or sticky.

Quick decision guide

Useful, but context matters

Ethylene/Zinc Acrylate 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 Ethylene/Zinc Acrylate 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 ethylene and zinc acrylate, designed to create a water-resistant film on the skin.

How it works

When applied, the copolymer dries into a continuous, flexible layer that physically blocks water and sweat from washing away the product. It also helps other ingredients spread evenly and feel smoother on the skin.

Pros

Boosts water resistance

Helps sunscreens and makeup stay effective even when you sweat or swim, so you don't have to reapply as often.

Improves product feel

Creates a smooth, non-greasy finish that makes creams and lotions spread easily and feel lightweight.

Cons and cautions

No active benefit

This ingredient only helps with texture and durability—it doesn't moisturize, soothe, or treat skin concerns.

Potential tightness

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

Best for

  • Anyone using water-resistant sunscreen or long-wear makeup
  • People with normal to oily skin who want products to stay put

Use caution if

  • Those with extremely dry or compromised skin barriers who may find film-formers uncomfortable

Usage tips

Use a gentle cleanser or oil-based makeup remover to fully wash off products containing this polymer.
If you have dry skin, apply a moisturizer underneath products with this ingredient to avoid any tight feeling.

Safety summary

Ethylene/Zinc Acrylate Copolymer is considered safe for topical use. It has low irritation and comedogenic potential, making it suitable for most skin types. No significant safety concerns have been reported in cosmetic concentrations.

Research notes

Research on this specific copolymer is limited, but similar acrylate copolymers have been extensively studied for safety and efficacy as film-formers. Regulatory reviews confirm low skin irritation and sensitization risk.

Common label clues

Typical concentration
0.5% to 5%
Regulatory status
Approved for use in cosmetics by the FDA and EU CosIng database. No concentration limits are specified for safety.
