Acrylates/Beheneth-25 Methacrylate/HEMA Crosspolymer

INCI: ACRYLATES/BEHENETH-25 METHACRYLATE/HEMA CROSSPOLYMER

A safe, synthetic thickener that gives products a smooth, non-greasy feel and helps keep ingredients evenly mixed.

In plain English

This is a man-made ingredient that helps lotions, creams, and sunscreens have a nice, silky texture. It stops the product from separating into watery and oily layers and makes it spread easily on your skin without feeling sticky or heavy.

Quick decision guide

Useful, but context matters

Acrylates/Beheneth-25 Methacrylate/HEMA 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.

  1. 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.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A synthetic crosspolymer made from acrylic acid derivatives and a long-chain fatty alcohol (beheneth-25). It is designed to thicken water-based formulas and improve their stability.

How it works

When added to water, the polymer chains swell and form a network that traps water, increasing viscosity. It also helps suspend particles (like sunscreen minerals) and creates a thin, flexible film on the skin that can improve water resistance and wear.

Pros

Lightweight feel

Provides a silky, non-greasy texture that absorbs quickly, making it ideal for daytime moisturizers and sunscreens.

Formula stability

Helps keep oil and water phases mixed, preventing separation and ensuring you get a consistent product every time.

Cons and cautions

Synthetic origin

As a man-made polymer, it may not be suitable for those who prefer 100% natural ingredient lists.

Potential tackiness

In high concentrations or certain formulations, it can leave a slightly sticky or tacky residue on the skin.

Best for

  • Anyone who enjoys lightweight, non-greasy moisturizers or sunscreens
  • People with oily or combination skin looking for a matte finish

Use caution if

  • Those who strictly avoid all synthetic ingredients in their skincare

Usage tips

Apply to damp skin for easier spreading and a more even finish.
Layer lighter products (like serums) before heavier creams containing this polymer to avoid pilling.

Safety summary

Generally recognized as safe for topical use. Low irritation and comedogenic potential. No significant safety concerns reported in cosmetic applications.

Research notes

Limited independent studies specific to this polymer, but it is structurally similar to other well-studied acrylate crosspolymers that have a strong safety profile in cosmetics.

Common label clues

Typical concentration
0.1% to 2%
Regulatory status
Approved for use in cosmetics in the US, EU, and many other regions. No known restrictions at typical usage levels.
Common uses
Moisturizers, Sunscreens, Serums, 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 ingredient is commonly used in 'invisible' or 'clear' sunscreens because it helps disperse mineral filters evenly.
  • It is considered safe by major regulatory bodies when used within typical concentrations.
