What Is C6-14 Perfluoroalkylethyl Acrylate/Hema Copolymer?
C6-14 Perfluoroalkylethyl Acrylate/HEMA Copolymer is a man-made polymer created by linking two smaller building blocks: 2-(perfluoro(C6-14 alkyl)) ethyl acrylate and 2-hydroxyethyl methacrylate. The result is a large, stable molecule that does not dissolve in water and forms a thin, flexible layer when it dries. The perfluoro side gives it water-repelling power while the HEMA part helps it grip the skin or hair.
Fluorinated polymers like this one first appeared in industrial coatings in the mid-20th century because of their resistance to oil and water. Cosmetic chemists soon noticed that the same properties could help makeup stay put and keep skincare formulas from rubbing off. The ingredient is produced in modern reactors where the two monomers are mixed with initiators, heated, and allowed to bond. The finished polymer is filtered, washed, and dried into a fine powder or dispersion ready for use in creams, lotions, and color products.
You will most often find C6-14 Perfluoroalkylethyl Acrylate/HEMA Copolymer in long-wear foundations, transfer-proof lipsticks, waterproof mascaras, sunscreens, and setting sprays. It also appears in some moisturizers and anti-aging treatments when a brand wants to add a light, breathable shield that locks active ingredients on the skin.
C6-14 Perfluoroalkylethyl Acrylate/Hema Copolymer’s Cosmetic Benefits/Uses
This ingredient earns its place in formulas thanks to two key technical roles
- Film forming: It dries into an invisible film that clings to skin or hair, boosting wear time for makeup, reducing color transfer onto clothes, and helping sunscreens stay put after sweating or swimming. The film is thin and flexible so it feels comfortable rather than tight or heavy.
- Viscosity controlling: It slightly thickens liquid or cream formulas, giving them a smooth, even texture that spreads easily. This helps prevent streaks in foundation or clumping in mascara and can keep active ingredients evenly suspended in a product so each application delivers the same dose.
Who Can Use C6-14 Perfluoroalkylethyl Acrylate/Hema Copolymer
This polymer is generally well tolerated by all skin types including oily, dry and combination because it forms a breathable film that does not fully block pores or trap oil. Those with very sensitive or compromised skin should watch for any tightness or irritation since any film former can feel uncomfortable on already inflamed skin.
The ingredient is fully synthetic and contains no animal derived substances so it is suitable for vegans and vegetarians.
No specific warnings exist for women who are pregnant or breastfeeding. The molecule stays on the surface of the skin and is not known to absorb into the bloodstream in meaningful amounts. Still, this is not medical advice and anyone who is pregnant or nursing should discuss any cosmetic product with a qualified healthcare provider before use just to be safe.
C6-14 Perfluoroalkylethyl Acrylate/HEMA Copolymer is not known to cause photosensitivity. It can actually help keep sunscreens in place, providing indirect support against UV exposure.
Potential Side Effects/Adverse Reactions
Responses to topical C6-14 Perfluoroalkylethyl Acrylate/Hema Copolymer differ from person to person. The issues listed below are possible yet uncommon when the ingredient is used at the levels found in finished cosmetic products.
- Mild skin irritation such as redness itching or a tingling sensation
- Allergic contact dermatitis in individuals already sensitized to acrylate or methacrylate type materials
- Eye stinging or watering if a product containing the polymer accidentally gets into the eyes
- Temporary feeling of dryness or tightness if multiple film forming products are layered without adequate moisturization
If you notice any of these reactions discontinue use and consult a medical professional for guidance.
Comedogenic Rating
Rating: 1/5
C6-14 Perfluoroalkylethyl Acrylate/HEMA Copolymer sits on the skin as a lightweight breathable film and has no inherent oils or waxes that can block pores. Its molecular size is too large to work its way into follicles where true clogging starts. A handful of users might see minor surface congestion if the polymer is layered with heavy occlusives but the polymer itself has very low pore-clogging potential.
Acne-prone individuals generally tolerate this ingredient well although results can vary depending on the full product formula.
Because the copolymer repels both oil and water it can sometimes make it harder for cleansers to fully remove long-wear makeup. Double cleansing or using an oil-based remover helps avoid residue that could indirectly contribute to breakouts.
Summary
C6-14 Perfluoroalkylethyl Acrylate/HEMA Copolymer acts mainly as a film former and mild viscosity controller. Its fluorinated side chains repel moisture while the acrylate backbone locks into place, creating a thin flexible layer that keeps pigments sunscreens and actives where you put them. At the same time its polymer structure ever so slightly thickens formulas giving creams and liquids a smoother glide.
While not as famous as silicones or classic film formers, this ingredient has carved out a niche in long-wear foundations, waterproof mascaras and modern reef-safe sunscreens. Brands that want bulletproof performance without a heavy feel reach for it more and more.
Safety data show a low irritation profile with minimal risk for pore blockage or systemic absorption. Still, everyone’s skin is unique so it is wise to patch test any new product containing the polymer before slathering it on daily.
