Ingredient review
Sorbeth-2/Oleate/Dimer Dilinoleate Crosspolymer
INCI: SORBETH-2/OLEATE/DIMER DILINOLEATE CROSSPOLYMER
A synthetic polymer that helps products feel smooth and stay put, but offers no active skincare benefit.
In plain English
This ingredient is a type of plastic-like polymer that forms a thin, flexible film on your skin. It's added to products like sunscreen and foundation to make them spread more evenly, feel silky, and resist water or sweat. Think of it as a gentle glue that helps the product stay in place without clogging pores or causing irritation.

Quick decision guide
Useful, but context matters
Sorbeth-2/Oleate/Dimer Dilinoleate 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 Sorbeth-2/Oleate/Dimer Dilinoleate 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 made by reacting sorbeth (a polyethylene glycol derivative), oleic acid, and dimer dilinoleic acid. It's a large molecule that doesn't absorb into the skin but sits on the surface.
How it works
When applied, the crosspolymer molecules link together to form a thin, flexible film on the skin. This film helps other ingredients (like sunscreen filters or pigments) spread evenly and stay put longer. It also gives the product a smooth, non-greasy feel and can boost water resistance.
Pros
Improves product performance
Helps sunscreen and makeup stay put longer, especially in water or sweat, so you get better protection and wear.
Silky, smooth feel
Creates a velvety texture that makes products glide on easily and feel lightweight on the skin.
Cons and cautions
No active benefit
This ingredient only improves texture and water resistance — it doesn't hydrate, soothe, or treat the skin.
Potential heaviness for oily skin
In high concentrations, the film may feel slightly heavy or sticky on very oily skin types.
Best for
- Anyone using water-resistant sunscreen or long-wear makeup
- People who prefer a silky, non-greasy finish
Use caution if
- Those with extremely oily skin who dislike any film-forming feel
- Anyone seeking active hydration or antioxidant benefits
Usage tips
Safety summary
Considered safe for topical use at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for most skin types. No significant safety concerns have been reported.
Research notes
Limited peer-reviewed studies specifically on this polymer, but crosspolymer film-formers in general are well-tolerated and widely used in cosmetics. Safety assessments by industry panels support its use.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the U.S. FDA and EU CosIng database, with no known restrictions at typical concentrations.
- Common uses
- Sunscreens, Foundations, Water-resistant creams
- Environmental note
- As a synthetic polymer, it may not be biodegradable. However, it is used in small amounts and is typically removed during wastewater treatment.
Good to know
- This polymer is not absorbed into the skin — it stays on the surface and washes off with cleansing.
- It's commonly used in 'water-resistant' sunscreens to help the SPF last longer during swimming or sweating.
