Ingredient review
PEG/PPG Glyceryl Ether Crosspolymer
INCI: PEG-15/PPG-70 GLYCERYL ETHER/IPDI/DMPA CROSSPOLYMER
A synthetic polymer that helps products stay put and feel smooth, but offers no active skincare benefit.
In plain English
This is a man-made ingredient that forms a thin, flexible film on your skin. It helps other ingredients spread evenly and makes products more water-resistant, so your sunscreen or makeup lasts longer. Think of it like a gentle glue that holds the product together without clogging pores.

Quick decision guide
Useful, but context matters
PEG/PPG Glyceryl Ether Crosspolymer 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 PEG/PPG Glyceryl Ether Crosspolymer.
- 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 crosspolymer created by reacting PEG/PPG glyceryl ether with IPDI (isophorone diisocyanate) and DMPA (dimethylolpropionic acid). It is a film-forming agent used to improve the texture, spreadability, and water resistance of cosmetic formulations.
How it works
When applied, the polymer molecules link together to form a thin, flexible film on the skin. This film helps other ingredients (like UV filters or pigments) adhere better and resist being washed away by water or sweat. It also gives products a smooth, silky feel.
Pros
Boosts water resistance
Helps sunscreens and makeup stay effective longer when you sweat or swim.
Improves product feel
Gives a silky, non-sticky finish that makes application smoother.
Cons and cautions
Synthetic and non-biodegradable
Made from petrochemicals and may not break down easily in the environment.
No active skincare benefit
It only improves texture and wear—it doesn't hydrate, brighten, or protect skin.
Best for
- Anyone wanting longer-lasting sunscreen or makeup
- People who prefer smooth, non-greasy textures
Use caution if
- Those strictly avoiding synthetic or PEG-based ingredients
- Individuals with known sensitivity to isocyanate derivatives (rare)
Usage tips
Safety summary
Generally recognized as safe for topical use at typical concentrations. The PEG and isocyanate components are processed to minimize impurities. Rare allergic reactions are possible, but irritation and comedogenicity are low.
Research notes
Safety data is based on general polymer toxicology and industry experience. No major clinical studies specifically on this ingredient, but similar crosspolymers have a long history of safe use in cosmetics.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. No specific concentration limits are imposed, but formulators follow good manufacturing practices.
- Common uses
- Sunscreens, Waterproof makeup, Long-wear foundations
- Environmental note
- As a synthetic polymer, it is not readily biodegradable. Some jurisdictions are reviewing microplastic-like ingredients, but this crosspolymer is typically used at low levels.
Good to know
- PEG compounds can be processed to remove impurities; this ingredient is generally considered safe at low concentrations
- Often combined with other film-formers for extra durability
