Ingredient review
Polyacrylate-33
INCI: Polyacrylate-33
Polyacrylate-33 is a synthetic polymer that helps products spread smoothly and feel lightweight, but it offers no active skincare benefits.
In plain English
Polyacrylate-33 is a man-made ingredient that forms a thin, flexible film on your skin. It helps lotions and serums glide on easily, feel silky rather than sticky, and resist washing off with water or sweat. Think of it like a very light, invisible glove that holds the product in place without clogging pores.

Quick decision guide
Useful, but context matters
Polyacrylate-33 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-33.
- 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-33 is a synthetic polymer — a long chain of repeating molecules — designed to improve the texture and wear of cosmetic products. It belongs to the acrylate family and is produced through chemical polymerization.
How it works
When applied, Polyacrylate-33 dries into a thin, flexible film on the skin's surface. This film helps other ingredients stay put, reduces water loss from the product (improving water resistance), and gives a smooth, non-tacky feel. It also slightly thickens the formula, making it easier to spread evenly.
Pros
Lightweight texture
Polyacrylate-33 gives products a silky, non-greasy feel that absorbs quickly, making it ideal for oily or combination skin types.
Water resistance
It helps sunscreens and makeup stay effective longer during sweating or swimming, reducing the need for frequent reapplication.
Cons and cautions
No active benefit
Unlike humectants or antioxidants, Polyacrylate-33 does not hydrate, repair, or protect skin — it only improves product feel and wear.
Potential tightness
The film it forms can feel slightly tightening or drying on very dry or compromised skin, especially in high concentrations.
Best for
- Anyone who prefers lightweight, fast-absorbing textures
- People looking for water-resistant sunscreens or long-wear makeup
Use caution if
- Those who prefer oil-based or rich, emollient formulas
Usage tips
Safety summary
Polyacrylate-33 has a low irritation and comedogenic risk. It is generally well-tolerated, but individuals with very sensitive or dry skin may notice a slight tightening sensation. No serious safety concerns have been reported in cosmetic use.
Research notes
Evidence for Polyacrylate-33 is based on its chemical properties and industry use rather than clinical studies on skin benefits. Safety assessments by cosmetic ingredient panels support its use at typical levels.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the EU, USA, and many other regions. The Cosmetic Ingredient Review (CIR) panel has evaluated similar acrylate polymers and found them safe as used.
- Common uses
- Serums, Moisturizers, Sunscreens, Makeup primers
- Environmental note
- As a synthetic polymer, Polyacrylate-33 is not biodegradable. However, it is used in low concentrations and is not known to bioaccumulate significantly.
Good to know
- Polyacrylate-33 is often used in combination with other film-formers to balance flexibility and durability.
- It is considered safe for use in cosmetics by major regulatory bodies at typical concentrations.
