Ingredient review
Bis-HEA IPDI/PPG-53 Copolymer
INCI: BIS-HEA IPDI/PPG-53 COPOLYMER
A synthetic film-former that helps products stay put and resist water, but offers no active skincare benefit.
In plain English
This is a man-made polymer that dries down to form a thin, flexible film on your skin or hair. Think of it like an invisible, breathable shield that helps makeup last longer, sunscreen stay effective even when you sweat, or hairspray hold your style. It's not absorbed into the skin and works purely on the surface.

Quick decision guide
Useful, but context matters
Bis-HEA IPDI/PPG-53 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.
- Step 1Start with the score, then check the irritation and clogging risk before judging Bis-HEA IPDI/PPG-53 Copolymer.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- 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
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic copolymer created by reacting isophorone diisocyanate (IPDI) with PPG-53 (a polypropylene glycol chain) and bis-hydroxyethyl acrylate (HEA). The result is a large molecule that forms a continuous film when the water or solvent evaporates.
How it works
When applied, the copolymer's molecules spread evenly over the skin or hair. As the product dries, the molecules link together into a flexible, water-resistant film. This film physically blocks water from reaching the underlying product (like sunscreen filters or pigment) and helps the product stay in place without flaking or feeling stiff.
Pros
Flexible film
Unlike some stiff polymers, this copolymer creates a film that bends with your skin's natural movements, reducing cracking or flaking throughout the day.
Water resistance booster
It significantly improves the water and sweat resistance of sunscreens and makeup, meaning you don't have to reapply as often during swimming or exercise.
Cons and cautions
No skincare benefit
This ingredient is purely functional—it doesn't hydrate, soothe, or protect the skin. It's a helper, not an active ingredient.
Removal challenge
Because it forms a water-resistant film, products containing this polymer often require an oil-based cleanser or double cleansing to remove completely, which can be inconvenient.
Best for
- Anyone wanting long-lasting, water-resistant makeup or sunscreen
- People with oily or combination skin who prefer transfer-proof formulas
Use caution if
- Those with very dry or dehydrated skin, as the film may accentuate dryness
Usage tips
Safety summary
Bis-HEA IPDI/PPG-53 Copolymer is considered safe for use in cosmetics at typical concentrations. It is a large molecule that does not penetrate the skin, so irritation and allergy risks are very low. No significant safety concerns have been raised by regulatory bodies.
Research notes
Safety assessments rely on the ingredient's large molecular size and lack of skin penetration. It is similar to other film-forming polymers that have a long history of safe use in cosmetics. Specific peer-reviewed studies on this exact copolymer are limited, but the class of polyurethane-based film formers is well-established as safe.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific concentration restrictions are common at typical use levels.
- Common uses
- Sunscreens, Long-wear foundations, Waterproof mascaras, Hair styling products
- Environmental note
- As a synthetic polymer, its biodegradability is limited. However, it is used in small amounts and is not known to bioaccumulate significantly.
Good to know
- This ingredient is often found in 'long-wear' or '24-hour' makeup and water-resistant sunscreens.
- It is not absorbed into the skin and sits only on the surface, making it generally safe for most skin types.
