Ingredient review
Hexylene Glycol Dimethacrylate Crosspolymer
INCI: HEXYLENE GLYCOL DIMETHACRYLATE/GLYCOL DIMETHACRYLATE CROSSPOLYMER
A synthetic polymer that helps products spread smoothly and stay put, 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 makeup or sunscreen glide on evenly and stay in place longer without feeling sticky or heavy. Think of it like a gentle, invisible net that holds the product where you put it.

Quick decision guide
Useful, but context matters
Hexylene Glycol Dimethacrylate 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 Hexylene Glycol Dimethacrylate 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 crosslinked polymer made from two types of methacrylate monomers. It is a synthetic, high-molecular-weight compound designed to create a flexible film on the skin.
How it works
When applied, the polymer chains link together to form a continuous, breathable film. This film improves the spreadability of the product, controls oil absorption, and helps other ingredients adhere to the skin for longer wear.
Pros
Improves wear time
Helps makeup and sunscreen stay in place longer, reducing the need for touch-ups throughout the day.
Smooth application
Creates a silky, even texture that makes products easier to blend and less likely to cake or streak.
Cons and cautions
No active benefits
This ingredient is purely a texture enhancer; it does not hydrate, soothe, or protect the skin on its own.
Synthetic origin
Made from petrochemical-derived monomers, which may be a concern for those seeking natural or minimal-ingredient routines.
Best for
- Anyone looking for long-lasting makeup or sunscreen
- People with normal to oily skin who want a matte finish
Use caution if
- Those who strictly avoid synthetic ingredients
- Individuals with known allergies to methacrylate compounds (rare)
Usage tips
Safety summary
Considered safe for topical use at typical concentrations. Low irritation and comedogenic potential. Rare allergic reactions possible in individuals sensitive to methacrylates.
Research notes
Limited peer-reviewed studies specifically on this polymer, but it is structurally similar to other widely used crosspolymers that have a strong safety record. The Cosmetic Ingredient Review (CIR) panel has reviewed related methacrylate polymers and found them safe as used.
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 known restrictions at typical use levels.
- Common uses
- Foundations, Primers, Sunscreens, Long-wear makeup
- Environmental note
- As a synthetic polymer, it is not biodegradable. However, it is used in very small amounts and is not known to bioaccumulate.
Good to know
- Commonly found in 'long-wear' or '24-hour' makeup products.
- Often used alongside silicones for a silky, non-tacky finish.
