Ingredient review
PPG-3 Glyceryl Ether Diacrylate/Adipate
INCI: PPG-3 GLYCERYL ETHER DIACRYLATE/ADIPATE
A synthetic film-former that helps nail polish and long-wear makeup stay put, but it offers no skincare benefit and may feel stiff on flexible surfaces.
In plain English
PPG-3 Glyceryl Ether Diacrylate/Adipate is a man-made polymer that creates a clear, flexible film when it dries. Think of it like a thin, invisible plastic wrap that helps nail polish resist chipping or helps lipstick stay on longer. It is not absorbed into the skin or nails; it just sits on the surface. Because it is synthetic, it is very consistent and predictable in formulas, but it does not moisturize or treat the nail or skin.

Quick decision guide
Useful, but context matters
PPG-3 Glyceryl Ether Diacrylate/Adipate 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 PPG-3 Glyceryl Ether Diacrylate/Adipate.
- 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 polymer created by reacting PPG-3 glyceryl ether with diacrylate and adipate compounds. It belongs to a class of ingredients called acrylate copolymers, which are widely used in cosmetics for their film-forming and binding properties.
How it works
When the solvent in a nail polish or makeup product evaporates, this ingredient forms a continuous, flexible film on the surface. This film adheres to the substrate (nail, lip, lash) and helps other pigments and ingredients stay in place. Its flexibility prevents the film from cracking or flaking off as the surface moves or bends.
Pros
Excellent durability
Creates a tough, flexible film that helps nail polish resist chipping and lip color resist transfer for hours.
Predictable performance
As a synthetic polymer, it delivers consistent film-forming properties batch after batch, unlike natural gums that can vary.
Cons and cautions
No skincare benefit
This ingredient only forms a surface film; it does not moisturize, strengthen, or treat the nail or lip skin.
Potential stiffness
On very flexible surfaces like lips, the film can feel slightly stiff or heavy, especially in high concentrations.
Best for
- Anyone wanting long-lasting nail polish or lip color
- People who prefer synthetic, predictable ingredients over natural gums or waxes
Use caution if
- Those seeking nail or lip treatments with nourishing or hydrating benefits
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. The ingredient is not absorbed through the skin or nails and has a low irritation and sensitization potential. No significant safety concerns have been raised by regulatory bodies.
Research notes
Safety is supported by the long history of use of acrylate copolymers in cosmetics and by reviews from the Cosmetic Ingredient Review (CIR) panel, which has found similar film-forming polymers safe as used. Specific studies on this exact ingredient are limited, but its chemical class is well-understood.
Common label clues
- Typical concentration
- Typically 1–10% in nail and makeup formulations
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU (CosIng), and many other regions. No specific concentration restrictions are common, but formulators follow good manufacturing practices.
- Common uses
- Nail polishes, Long-wear lip products, Mascara, Eyeliners
- Environmental note
- As a synthetic polymer, it is not biodegradable. However, it is used in small amounts in products that are typically disposed of via household waste, not rinsed down drains.
Good to know
- This ingredient is not water-soluble, so it will not wash off with water alone.
- It is often combined with plasticizers to fine-tune flexibility in nail formulas.
- The 'PPG-3' prefix indicates a propylene glycol chain of 3 units, which helps control the polymer's flexibility and compatibility.
