INCI name
Allyl Methacrylates Crosspolymer

Allyl Methacrylates Crosspolymer is a synthetic porous polymer derived from the suspension polymerization method, similar to that used to make latex paints. It forms spherical particles with a median size of about 40 μm. The spheres' interior comprises clusters of small spheres, which are then agglomerated together to form the porous exterior surface and a hollow interior.

It is a fine white powder insoluble in water. Allyl Methacrylates Crosspolymer is a multifunctional ingredient used in cosmetics and personal care products that acts as an ingredient-carrying agent, adsorber, controlled realize agent, thickenter, and emollient.

Allyl Methacrylates Crosspolymer can adsorb oils and water-based liquids in huge quantities. For example, a gram of this polymer can adsorb up to 12 grams of oil and 8 grams of water before losing its ability to be a free-flowing powder. The combination of capillary action and dual affinity for the polymeric matrix of Allyl Methacrylates Crosspolymer ensures a high load of active ingredients into this delivery vehicle. Applied to the skin, it provides sustained release and prolonged action of loaded actives.

Thanks to its porous structure, Allyl Methacrylates Crosspolymer can provide additional benefits, like sebum control, similar to several mineral and natural ingredients that adsorb excess sebum. It can also be used in pressed powder-type formulations that carry high amounts of lipophilic actives while providing a pleasant feel to the skin.

As a delivery vehicle, Allyl Methacrylates Crosspolymer can carry and control the release of vitamins, AHAs, and other ingredients in skincare and makeup products. It is also helpful for the controlled release of fragrances in powders, antiperspirants, and other cosmetics/personal care products, as well as antimicrobials in antiperspirants, foot powders, and other applications.

Thanks to active entrapment, Allyl Methacrylates Crosspolymer improves the stability of unstable ingredients such as ascorbic acid and retinoids. It improves the physical stability of products and prevents syneresis in antiperspirants and sweating in lipsticks.

In addition, Allyl Methacrylates Crosspolymer improves dispersions of difficult-to-disperse or difficult-to-handle ingredients, enriches product cosmetic elegance and skin feel, and enhances salt tolerance of carbomer emulsions. It increases the viscosity of formulations and reduces irritation with entrapped skin sloughing agents.
