Ingredient review
Polyacrylate-34
INCI: Polyacrylate-34
A synthetic polymer that helps create smooth, lightweight gel textures and improves water resistance, but offers no direct skin benefit.
In plain English
Polyacrylate-34 is a synthetic ingredient that helps skincare products feel silky and lightweight. It forms a thin, flexible film on the skin that can help other ingredients stay put and improve water resistance. Think of it as a texture helper — it doesn't actively treat your skin, but it makes the product feel nicer and last longer on your face.

Quick decision guide
Useful, but context matters
Polyacrylate-34 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-34.
- 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-34 is a high-molecular-weight synthetic polymer belonging to the polyacrylate family. It is manufactured through polymerization of acrylic acid monomers and is used primarily as a thickening agent and film former in cosmetic formulations.
How it works
When applied to the skin, Polyacrylate-34 forms a thin, flexible film that helps lock in other ingredients and improves the water resistance of the product. It also increases the viscosity of water-based formulas, creating smooth, non-greasy gels that spread easily and feel lightweight.
Pros
Lightweight feel
Creates a silky, non-greasy texture that absorbs quickly, making it ideal for oily or combination skin types.
Improves product performance
Helps sunscreens and makeup stay put longer by forming a water-resistant film, reducing the need for reapplication.
Cons and cautions
No active skin benefit
Polyacrylate-34 is purely a texture and stability ingredient — it doesn't hydrate, soothe, or treat the skin in any way.
Potential for irritation in compromised skin
The film it forms may feel occlusive or uncomfortable on very sensitive or damaged skin, though irritation is rare for most people.
Best for
- People who prefer lightweight, non-greasy gel textures
- Those looking for water-resistant sunscreens or long-wear makeup
Use caution if
- Individuals with very sensitive or damaged skin barriers who may prefer simpler formulas
Usage tips
Safety summary
Polyacrylate-34 is considered safe for most people when used in typical cosmetic concentrations. It has low irritation and comedogenic potential, but those with very sensitive or compromised skin may want to patch test first.
Research notes
Polyacrylates are well-studied as cosmetic ingredients. The CIR panel has reviewed similar polymers and found them safe for topical use. However, individual studies on Polyacrylate-34 specifically are limited, and most safety data comes from the broader polyacrylate family.
Common label clues
- Typical concentration
- 0.1% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has evaluated polyacrylates and found them safe when formulated to be non-irritating.
- Common uses
- Gels, Serums, Moisturizers, Sunscreens, Makeup primers
- Environmental note
- As a synthetic polymer, Polyacrylate-34 is not biodegradable and may contribute to microplastic pollution if washed down drains. Some brands are moving toward biodegradable alternatives.
Good to know
- Polyacrylate-34 is often used in combination with other polymers to achieve specific gel textures.
- It is considered safe for use in cosmetics by major regulatory bodies at typical concentrations.
