Ingredient review
PPG-26/Dimer Dilinoleate Copolymer
INCI: PPG-26/Dimer Dilinoleate Copolymer
A safe, synthetic polymer that creates a flexible film on skin, improving water resistance and texture without common irritation.
In plain English
This ingredient is a man-made polymer (a long chain of repeating molecules) that forms a thin, flexible film on your skin. It helps other ingredients stay put, makes products feel silky, and improves water resistance. Think of it like a gentle, invisible shield that helps your makeup or sunscreen last longer without feeling heavy or sticky.

Quick decision guide
Useful, but context matters
PPG-26/Dimer Dilinoleate 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 PPG-26/Dimer Dilinoleate 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
PPG-26/Dimer Dilinoleate Copolymer is a synthetic polymer created by reacting propylene glycol (PPG) with dimer dilinoleic acid. It belongs to a class of ingredients called film formers, which are used to create a continuous layer on the skin or hair.
How it works
When applied, the polymer molecules spread out and link together to form a thin, flexible film. This film helps other ingredients (like pigments or UV filters) adhere to the skin, reduces transfer, and provides water resistance. It also thickens the product, giving it a pleasant, smooth texture.
Pros
Enhances wear time
Creates a flexible film that helps makeup and sunscreen stay put for hours, reducing the need for frequent touch-ups.
Improves texture
Gives products a smooth, silky feel that glides on easily, making application more pleasant.
Cons and cautions
Synthetic origin
Not derived from natural sources, which may be a drawback for those seeking plant-based or 'clean' beauty products.
Potential heaviness
In high concentrations, it can feel slightly heavy or tacky on very oily skin, though this is uncommon in well-formulated products.
Best for
- Anyone wanting longer-lasting makeup or sunscreen
- People who swim or sweat and need water-resistant products
Use caution if
- Those who prefer 100% natural or plant-based ingredients
Usage tips
Safety summary
PPG-26/Dimer Dilinoleate Copolymer is considered safe for use in cosmetics. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in peer-reviewed studies or regulatory reviews.
Research notes
Research on this specific polymer is limited, but it belongs to a well-studied class of film-forming polymers. Safety assessments by the Cosmetic Ingredient Review (CIR) panel have found similar polymers to be safe at typical use levels.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics globally, including by the U.S. FDA and the European Commission, with no known restrictions at typical concentrations.
- Common uses
- Sunscreens, Foundations, Lip products, Water-resistant formulations
- Environmental note
- As a synthetic polymer, it is not biodegradable. However, it is used in small amounts and is not known to accumulate in the environment.
Good to know
- This polymer is often used alongside silicones to create a smooth, non-greasy finish.
- It is considered safe and non-irritating by major regulatory bodies.
