What Is Polyacrylate Crosspolymer-6?

Polyacrylate Crosspolymer-6 is a lab-created copolymer made by linking together several acrylic-based monomers, including ammonium acryloyldimethyltaurate, dimethylacrylamide, lauryl methacrylate and laureth-4 methacrylate, then crosslinking them with trimethylolpropane triacrylate. The result is a three-dimensional network that swells in water and forms a smooth flexible gel. First introduced in the early 2000s as a modern alternative to traditional carbomers, it quickly gained popularity because it works in a wider pH range and feels lighter on the skin.

Production starts with each monomer dissolved in water, followed by controlled free-radical polymerization. The growing chains are joined by the crosslinker, which locks the structure into microspheres that later disperse easily in water-based or emulsion systems. After purification and drying, the powder is ready for cosmetic labs.

Because of its ability to thicken without leaving a heavy film, Polyacrylate Crosspolymer-6 appears in sheet masks, lightweight moisturizers, hydrating serums, sunscreens, peel-off masks, color cosmetics, after-sun gels, men’s grooming products and even water-based primers.

Polyacrylate Crosspolymer-6’s Cosmetic Benefits/Uses

Formulators turn to this ingredient for two key technical reasons that translate into better texture and performance for the user:

  • Emulsion stabilising – Keeps oil and water phases from separating so creams, lotions and sunscreens stay uniform throughout their shelf life, which means consistent application and improved active delivery
  • Viscosity controlling – Builds thickness at low use levels, giving products a silky gel feel without greasiness and allowing brands to adjust flow so pumps dispense easily and jars hold their shape

Who Can Use Polyacrylate Crosspolymer-6

This texture enhancer is considered friendly for all major skin types including oily, combination, normal and dry because it is non occlusive and free of common irritants like fragrance or essential oils. Sensitive and acne-prone users usually tolerate it well although anyone with a known acrylic polymer allergy should steer clear.

Polyacrylate Crosspolymer-6 is made entirely from synthetic building blocks so it contains no animal derived materials. That makes it suitable for vegans and vegetarians.

Current safety assessments show no reproductive or developmental concerns at the concentrations used in cosmetics. Still this is not medical advice. Pregnant or breastfeeding individuals should review any product containing the ingredient with their healthcare provider for personal guidance.

The polymer does not make skin more reactive to sunlight and has no known photosensitising effect.

Because it is water-swelling and inert it also plays nicely when layered with actives such as vitamin C, retinoids or niacinamide without affecting their efficacy.

Potential Side Effects/Adverse Reactions

Reactions to topical Polyacrylate Crosspolymer-6 differ from person to person. The points below outline potential issues only; most users will not notice any of these when the product is formulated and applied as intended.

  • Mild skin irritation or redness in individuals allergic to acrylic polymers
  • Transient stinging on compromised or freshly exfoliated skin
  • Eye irritation if the gel accidentally enters the eyes before fully setting

If any unpleasant reaction occurs stop using the product and seek medical advice

Comedogenic Rating

Rating: 0 / 5

Polyacrylate Crosspolymer-6 is a large water-swellable molecule that sits on the surface then rinses or rubs away without blocking pores. It lacks oily components, does not form an occlusive film and is used at very low concentrations, all of which keep its clogging potential virtually nil.

That makes it suitable for people who are prone to acne or breakouts.

Because it helps create lightweight oil-in-water formulas, it may actually improve the feel of products designed for blemish-prone skin.

Summary

Polyacrylate Crosspolymer-6 acts primarily as an emulsion stabiliser and viscosity controller. Its three-dimensional network thickens the water phase, suspends oil droplets and pigments then holds everything in place so the formula stays uniform from the lab to your bathroom shelf.

The polymer has gained steady popularity since the early 2000s thanks to its silky feel, broad pH tolerance and ease of use compared with older carbomers. You will spot it in modern gels, serums, sunscreens and light creams.

Current safety reviews show it to be low risk with minimal irritation potential when used as directed. As with any new skincare ingredient it is wise to perform a quick patch test the first time you try a product that contains it just to be sure your skin agrees.
