Ingredient review
Acrylates/Palmeth-25 Itaconate Copolymer
INCI: ACRYLATES/PALMETH-25 ITACONATE COPOLYMER
A safe, synthetic polymer that improves product feel and longevity without common irritation concerns.
In plain English
This ingredient is a synthetic polymer that forms a thin, flexible film on your skin or hair. Think of it like a very lightweight, invisible layer that helps other ingredients stay put and gives products a smooth, silky feel. It's commonly used in makeup and sunscreens to improve how they spread and how long they last.
Quick decision guide
Useful, but context matters
Acrylates/Palmeth-25 Itaconate 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 Itaconate 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) combined with itaconic acid. It is designed to create a flexible, water-resistant film on surfaces.
How it works
When applied, the polymer molecules link together as the water or solvent evaporates, forming a continuous, flexible film. This film helps other ingredients (like pigments or UV filters) adhere to the skin or hair, improves water resistance, and can control the thickness or texture of the product.
Pros
Improves product performance
Helps makeup and sunscreen last longer without smudging or rubbing off easily.
Non-irritating for most
Generally considered safe and low-risk for irritation or clogging pores, making it suitable for sensitive skin.
Cons and cautions
Palm-derived source
The palmeth-25 component comes from palm oil, which may be a concern for those avoiding palm derivatives due to environmental impact.
Not biodegradable
As a synthetic polymer, it does not break down easily in the environment, which may be a consideration for eco-conscious users.
Best for
- Anyone looking for long-wearing makeup or sunscreen
- People with normal to oily skin who want a matte or smooth finish
Use caution if
- Those with a strong preference for 100% natural or biodegradable ingredients
- Individuals with known allergies to acrylate polymers (rare)
Usage tips
Safety summary
Acrylates/Palmeth-25 Itaconate Copolymer is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. The main concerns are environmental (biodegradability and palm sourcing).
Research notes
There is limited peer-reviewed research specifically on this copolymer, but it is structurally similar to other well-studied acrylate copolymers used in cosmetics. Safety assessments by industry panels (e.g., CIR) have found acrylate copolymers generally safe. More research on environmental fate is needed.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU (CosIng), and many other regions. No specific concentration restrictions are common.
- Common uses
- Foundations, Sunscreens, Hair styling products, Moisturizers
- Environmental note
- As a synthetic polymer, it is not readily biodegradable. The palm-derived component may contribute to deforestation concerns unless sourced sustainably (RSPO-certified).
Good to know
- This ingredient is often used in combination with other film formers to achieve a specific texture or water-resistance level.
- It is considered safe by major cosmetic regulatory bodies when used as intended.
