What Is Polyacrylate-27?
Polyacrylate-27 is a man-made polymer created by linking together smaller building blocks called monomers. In this case the recipe blends vintyl toluene, 2-ethylhexyl acrylate, 2-hydroxyethyl methacrylate, vinyl imidazole and methoxy PEG-8 methacrylate. When these pieces join they form a flexible mesh that behaves like a soft film on the skin. The ingredient was introduced in the late 1990s during the rise of advanced gel technologies, as brands started searching for lightweight alternatives to heavy waxes and oils.
The manufacturing process relies on controlled free-radical polymerization. Chemists mix the monomers in a reactor, add an initiator to kick-start the reaction then adjust temperature and pH until long chains form. After purification and drying the result is a fine white powder or viscous liquid that blends easily into water-based or water-and-oil formulas.
Because of its ability to thicken, stabilize and create a smooth surface Polyacrylate-27 shows up in many everyday items such as light moisturizers, sheet mask serums, leave-on conditioners, setting sprays, face primers and oil-free sunscreens. It helps these products feel fresh and non-greasy while still staying put on the skin.
Polyacrylate-27’s Cosmetic Benefits/Uses
This multitasking polymer adds several helpful qualities to modern skincare and makeup.
- Emulsion stabilising – Keeps water and oil phases from separating so lotions and creams stay smooth throughout their shelf life and glide on evenly
- Film forming – Creates a breathable layer that locks in moisture, boosts spreadability and enhances the staying power of pigments or actives
- Cleansing – Helps lift away dirt and makeup by surrounding oily particles, making rinse-off products more effective without stripping the skin
Who Can Use Polyacrylate-27
Thanks to its light texture and low likelihood of clogging pores, Polyacrylate-27 suits most skin types including oily, combination, normal and even sensitive skin. Very dry skin may want to pair it with richer emollients since the ingredient itself is not deeply nourishing, but it will not worsen dryness on its own.
The polymer is fully synthetic and does not originate from animal sources, so it is suitable for both vegans and vegetarians. Manufacturing does not typically rely on animal based processing aids.
No data suggest that Polyacrylate-27 poses a risk to pregnant or breastfeeding women when used topically. It is a large molecule that stays on the surface and is unlikely to penetrate into the bloodstream. This is not medical advice and anyone who is pregnant or nursing should check with a doctor before starting any new skincare product, just to be safe.
The ingredient does not make skin more sensitive to sunlight and can be worn in daytime formulas without additional sun related precautions.
Potential Side Effects/Adverse Reactions
Reactions to Polyacrylate-27 are uncommon and tend to differ from person to person. The points below outline possible but unlikely side effects assuming the ingredient has been properly included in a finished product.
- Mild stinging or redness in individuals with very reactive skin, usually subsides quickly once the product is rinsed off
- Contact dermatitis in people who already have an allergy to acrylates or methacrylates
- Temporary eye irritation if the product accidentally gets into the eyes during application
- Isolated breakouts in acne prone users if heavy layers trap existing bacteria under the thin film
If you experience any of the above, discontinue use and consult a healthcare professional for guidance.
Comedogenic Rating
Rating: 1 / 5. Polyacrylate-27 is a large, water-loving polymer that stays on the surface and does not sink into pores, so it has little tendency to block them. The thin breathable film it forms lets sweat and sebum escape, which keeps the risk of congestion low.
Because of this low score most people who deal with acne or frequent breakouts can use products containing Polyacrylate-27 without added concern, provided the overall formula is lightweight and oil balanced.
Keep in mind that finished products also contain other ingredients that may be more pore clogging, so always consider the full ingredient list when evaluating breakout risk.
Summary
Polyacrylate-27 works in three main ways: it stabilises emulsions by holding water and oil together, forms a flexible film that locks in moisture while giving products lasting power, and aids cleansing by surrounding dirt and makeup so they rinse away easily. Its popularity sits in the mid range; not every brand uses it but formulators appreciate its ability to replace heavier waxes and improve the feel of gel textures.
Safety data show a very low incidence of irritation or allergy and the polymer is too large to penetrate living skin, making it a generally safe choice for daily use. As with any new cosmetic ingredient it is best to patch test a fresh product on a small area first to make sure your skin agrees with it.
