Acrylates/Beheneth-25 Methacrylate/HEMA Crosspolymer-2
INCI: ACRYLATES/BEHENETH-25 METHACRYLATE/HEMA CROSSPOLYMER-2
A synthetic polymer that helps products feel smooth, spread evenly, and stay put without clogging pores.
In plain English
This is a man-made ingredient that forms a thin, flexible film on your skin. It helps creams and lotions feel silky, keeps makeup from smudging, and helps sunscreen stay effective longer. Think of it like a gentle, invisible net that holds everything together without feeling heavy or sticky.
Quick decision guide
Useful, but context matters
Acrylates/Beheneth-25 Methacrylate/HEMA Crosspolymer-2 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 Acrylates/Beheneth-25 Methacrylate/HEMA Crosspolymer-2.
- 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 high-molecular-weight synthetic polymer made from acrylic acid derivatives and fatty alcohol chains. It is designed to create a flexible film on the skin and to control the thickness and feel of cosmetic formulas.
How it works
When applied, the polymer molecules link together to form a thin, breathable film on the skin's surface. This film helps other ingredients stay in place, reduces water loss from the product, and gives a smooth, non-greasy finish. It also helps suspend particles like sunscreen minerals or pigments evenly.
Pros
Improves product feel
Creates a silky, smooth texture that makes creams and sunscreens easier to apply and more pleasant on the skin.
Boosts water resistance
Helps sunscreens and makeup stay effective longer when you sweat or get wet, reducing the need for frequent reapplication.
Cons and cautions
Synthetic origin
Made from petrochemical derivatives, which may be a concern for those seeking natural or minimal-ingredient routines.
Limited long-term data
While generally considered safe, there is less independent research on the long-term effects of repeated skin exposure compared to some simpler ingredients.
Best for
- Anyone looking for long-wear makeup or water-resistant sunscreen
- People with normal to oily skin who prefer a matte finish
Use caution if
- Those who strictly avoid synthetic ingredients in their routine
Usage tips
Safety summary
Acrylates/Beheneth-25 Methacrylate/HEMA Crosspolymer-2 is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. Some individuals may prefer to avoid synthetic polymers, but no significant safety concerns have been identified.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that acrylate crosspolymers are safe in cosmetics. Most data comes from industry-sponsored studies and regulatory reviews. Independent long-term human studies are limited, but no adverse effects have been reported in normal use.
Common label clues
- Typical concentration
- 0.1% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. Considered safe at typical concentrations by the Cosmetic Ingredient Review (CIR) panel.
- Common uses
- Sunscreens, Foundations, Moisturizers, Eye creams, Long-wear makeup
- Environmental note
- As a synthetic polymer, it may not be biodegradable. However, it is used in very small amounts and is not known to accumulate in the environment.
Good to know
- This polymer is often used in 'one-step' sunscreen and moisturizer combos because it helps stabilize the formula.
- It is not absorbed deep into the skin; it stays on the surface to form its protective film.
