INCI: BIS-HEA IPDI/PPG-26 COPOLYMER

A synthetic film-former that helps makeup and skincare stay put longer without feeling heavy or sticky.

beautyskincarefilm-former

In plain English

This ingredient is a man-made polymer that creates a thin, flexible film on your skin. Think of it like an invisible, breathable shield that helps your foundation or sunscreen stay in place longer, resist sweat and water, and feel smooth rather than greasy.

Quick decision guide

Useful, but context matters

Bis-HEA IPDI/PPG-26 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 Bis-HEA IPDI/PPG-26 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 isophorone diisocyanate (IPDI) and PPG-26, designed to form a flexible, water-resistant film on the skin or hair.

How it works

When applied, the copolymer molecules link together to form a continuous, flexible film. This film helps other ingredients (like pigments or UV filters) adhere to the skin, reduces transfer, and improves water resistance without clogging pores.

Pros

Long-lasting wear

Helps makeup and sunscreen resist fading, smudging, and transferring throughout the day.

Water-resistant boost

Improves water and sweat resistance, making it ideal for active lifestyles or humid climates.

Cons and cautions

Synthetic origin

Not biodegradable or naturally derived, which may be a concern for eco-conscious consumers.

Potential tightness on dry skin

In high concentrations, the film can feel slightly tight or uncomfortable on very dry or flaky skin.

Best for

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

Use caution if

  • Individuals with very dry or dehydrated skin who may find film-formers uncomfortable

Usage tips

Use in conjunction with a good moisturizer if you have dry skin to avoid any tight feeling.
Apply products containing this polymer evenly and avoid over-application to prevent a heavy feel.

Safety summary

Bis-HEA IPDI/PPG-26 Copolymer is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types.

Research notes

Safety assessments by industry panels (e.g., CIR) have reviewed similar film-forming polymers and found them safe for cosmetic use. Specific studies on this exact copolymer are limited, but its chemical class is well-tolerated.

Common label clues

Typical concentration
0.5% to 5%
Regulatory status
Approved for use in cosmetics globally, including by the FDA (as a cosmetic ingredient) and under EU CosIng regulations.
Common uses
Long-wear foundations, Waterproof mascaras, Sunscreens, Lip products
Environmental note
As a synthetic polymer, it is not readily biodegradable. However, it is used in low concentrations and is not known to bioaccumulate.

Good to know

  • This ingredient is often found in '24-hour wear' or 'waterproof' formulas.
  • It is considered safe and non-irritating by cosmetic safety panels at typical use levels.
