Ingredient review
Polyacrylate-41
INCI: Polyacrylate-41
A safe, synthetic film-former that helps products spread smoothly and stay put without clogging pores.
In plain English
Polyacrylate-41 is a synthetic ingredient that forms a thin, flexible film on your skin. It helps lotions and creams feel silky, spread easily, and resist washing off from water or sweat. Think of it like a gentle, invisible glove that helps your skincare or makeup last longer.

Quick decision guide
Useful, but context matters
Polyacrylate-41 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 Polyacrylate-41.
- 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
Polyacrylate-41 is a high-molecular-weight polymer made from acrylic acid derivatives. It belongs to the acrylate family and is designed to create a uniform, breathable film on the skin.
How it works
When applied, the polymer chains align to form a continuous film. This film improves the spreadability of the product, locks in other ingredients, and provides a water-resistant barrier without feeling heavy or sticky.
Pros
Lightweight feel
Unlike heavy waxes or oils, Polyacrylate-41 forms a thin, flexible film that doesn't weigh down the skin.
Water-resistant boost
It helps sunscreens and makeup stay effective longer during swimming, sweating, or humid conditions.
Cons and cautions
Synthetic origin
It is made from petroleum-derived acrylic acid, which may be a concern for those seeking fully natural formulations.
Potential tackiness
In high concentrations or certain formulas, it can leave a slightly sticky or tacky residue on the skin.
Best for
- Anyone looking for long-wearing makeup or water-resistant sunscreen
- People with normal to oily skin who prefer lightweight textures
Use caution if
- Those strictly avoiding all synthetic polymers
- Individuals with known acrylate allergy (rare)
Usage tips
Safety summary
Polyacrylate-41 has a low irritation and comedogenic risk. It is well-tolerated by most skin types, including sensitive skin. Allergic reactions are extremely rare.
Research notes
Safety data for acrylate copolymers is well-established through industry and regulatory reviews. No significant health concerns have been identified for topical use at cosmetic concentrations.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. The Cosmetic Ingredient Review (CIR) panel has evaluated acrylate copolymers and found them safe at typical concentrations.
- Common uses
- Sunscreens, Primers, Moisturizers, Makeup
- Environmental note
- As a synthetic polymer, it is not biodegradable. However, it is used in very small amounts and is not known to accumulate in the environment.
Good to know
- Polyacrylate-41 is often used in combination with other film-formers to balance texture and durability.
- It is considered safe by major regulatory bodies when used as directed.
