Ingredient review
Polyacrylate-43
INCI: POLYACRYLATE-43
Polyacrylate-43 is a synthetic film-former that helps products stay put and resist water, but it offers no skin benefit and may feel heavy on some skin types.
In plain English
Polyacrylate-43 is a man-made polymer that creates a thin, flexible film on your skin or hair. Think of it like a clear, invisible shield that helps makeup last longer or sunscreen stay on when you sweat. It doesn't moisturize or treat anything—it's purely a texture and performance helper. Because it's a plastic-like material, it can feel a bit tight or heavy if you use a lot, but for most people it's safe and non-irritating.

Quick decision guide
Useful, but context matters
Polyacrylate-43 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-43.
- 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-43 is a synthetic polymer belonging to the acrylate family. It is produced by polymerizing acrylic acid derivatives into long chains, creating a substance that can form a continuous film when applied to skin or hair.
How it works
When applied, the water in the product evaporates, leaving behind a thin, flexible film of Polyacrylate-43. This film physically blocks water and oil from moving through it, which helps waterproof sunscreens, prevents makeup from smudging, and holds hair styles in place. It also thickens the product's texture, making it feel richer and easier to spread.
Pros
Boosts water resistance
Helps sunscreens and makeup stay effective even when you sweat or swim, so you don't have to reapply as often.
Improves wear time
Creates a flexible film that keeps foundation and eye makeup from sliding off during the day.
Cons and cautions
Can feel heavy
On dry or sensitive skin, the film may feel tight, sticky, or uncomfortable, especially in high concentrations.
No skin benefit
Unlike humectants or antioxidants, Polyacrylate-43 does nothing to hydrate, soothe, or repair your skin—it's purely a texture aid.
Best for
- People who want long-wearing, water-resistant makeup or sunscreen
- Those with normal to oily skin who don't mind a slight film feel
Use caution if
- People with very dry or dehydrated skin who prefer lightweight, breathable formulas
- Those who avoid synthetic polymers for environmental reasons
Usage tips
Safety summary
Polyacrylate-43 is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, but may cause a temporary tight feeling on very dry skin. No serious health concerns have been identified in cosmetic use.
Research notes
Research on Polyacrylate-43 specifically is limited, but the broader class of acrylate copolymers has been reviewed by the Cosmetic Ingredient Review (CIR) panel, which concluded they are safe for use in cosmetics. Studies focus on their film-forming and water-resistance properties rather than biological effects.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other countries. The Cosmetic Ingredient Review (CIR) panel has reviewed acrylate copolymers and found them safe as used.
- Common uses
- Sunscreens, Waterproof makeup, Long-wear foundations, Hair styling products
- Environmental note
- As a synthetic polymer, Polyacrylate-43 is not biodegradable and may contribute to microplastic pollution. Some brands are moving toward biodegradable alternatives.
Good to know
- Polyacrylate-43 is often used alongside other film-formers like Dimethicone to balance feel and performance.
- It is considered safe by major regulatory bodies when used in typical cosmetic concentrations.
