Ingredient review
Acrylates Copolymer
INCI: SODIUM ACRYLATES/ETHYLHEXYL ACRYLATE COPOLYMER
A safe, synthetic polymer that helps products spread smoothly and stay put without feeling heavy.
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, spread easily, and resist washing off with water or sweat. Think of it like a gentle, invisible net that holds the product in place without clogging pores.
Quick decision guide
Useful, but context matters
Acrylates 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 Acrylates 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
A high-molecular-weight polymer made from acrylic acid and ethylhexyl acrylate monomers. It is a synthetic ingredient designed to improve the texture and stability of cosmetic formulations.
How it works
When applied, the polymer molecules link together to create a continuous film on the skin. This film reduces water loss from the product, improves spreadability, and helps active ingredients stay in contact with the skin longer. It also thickens the formula, giving it a luxurious feel.
Pros
Lightweight feel
Creates a silky, non-greasy texture that absorbs quickly, making it ideal for daytime use under makeup.
Water resistance
Helps sunscreens and long-wear products stay effective longer, even in humid conditions or during light activity.
Cons and cautions
Potential tightness
The film can feel slightly tightening or drying on very sensitive or dry skin, especially if used without a hydrating layer underneath.
Environmental persistence
As a synthetic polymer, it does not readily break down in nature, raising concerns about microplastic accumulation.
Best for
- Anyone who wants a lightweight, non-sticky moisturizer or sunscreen
- People with oily or combination skin who dislike heavy creams
Use caution if
- Those with extremely dry or compromised skin barriers may prefer a richer, oil-based formula
Usage tips
