Ingredient review
Acrylates/Palmeth-25 Acrylate Copolymer
INCI: ACRYLATES/PALMETH-25 ACRYLATE COPOLYMER
A safe, synthetic polymer that helps products spread smoothly and feel lightweight on skin.
In plain English
This ingredient is a synthetic polymer—a type of plastic-like molecule—that helps skincare and makeup products have a nice, smooth texture. When applied, it forms a very thin, flexible film on the skin or hair. This film can help other ingredients stay in place, reduce water loss from the skin, and give a silky, non-greasy feel. It is widely used because it is gentle and unlikely to clog pores or cause irritation.
Quick decision guide
Useful, but context matters
Acrylates/Palmeth-25 Acrylate 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/Palmeth-25 Acrylate 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 synthetic copolymer made from acrylic acid derivatives and a palm-derived fatty alcohol (palmeth-25). It is a white powder or liquid that is added to formulas to control thickness and create a film.
How it works
When mixed into a product, it helps thicken the formula and, once applied, dries down to form a thin, flexible film on the skin or hair. This film can lock in moisture, improve the wear of makeup, and reduce the greasy feel of oils.
Pros
Lightweight feel
Unlike heavy oils or waxes, this polymer gives a silky, non-sticky finish that works well for all skin types, especially oily or combination skin.
Improves product stability
It helps keep the formula from separating and ensures that active ingredients are delivered evenly every time you use the product.
Cons and cautions
Synthetic origin
It is man-made, which may be a turn-off for people who prefer naturally derived ingredients, even though it is considered safe.
Palm-derived component
The 'palmeth' part comes from palm oil, which can be associated with deforestation if not sourced responsibly. Look for RSPO-certified products if this concerns you.
Best for
- Anyone looking for lightweight, non-greasy moisturizers or sunscreens
- People who want makeup that lasts longer without smudging
Use caution if
- Those who strictly avoid all synthetic or palm-derived ingredients
Usage tips
Safety summary
Acrylates/Palmeth-25 Acrylate Copolymer is considered safe for use in cosmetics. It has low irritation and allergy potential, and is not known to clog pores. The Cosmetic Ingredient Review (CIR) panel has reviewed similar acrylate polymers and found them safe as used.
Research notes
Safety assessments for acrylate copolymers generally show very low skin irritation and sensitization. A 2021 CIR safety review of related polymers confirmed their safety in leave-on and rinse-off products. No significant health concerns have been raised in peer-reviewed literature.
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. No concentration limits are imposed.
- Common uses
- Moisturizers, Sunscreens, Makeup, Hair styling products
- Environmental note
- The palm-derived component may have environmental impacts related to palm oil cultivation. Choosing products with RSPO-certified palm derivatives can help reduce this concern.
Good to know
- This ingredient is often used in 'invisible' sunscreens because it helps the product disappear into the skin.
- It is considered non-comedogenic and safe for sensitive skin by dermatologists.
