Sodium Acrylates/C10-30 Alkyl Acrylate Crosspolymer
What is Sodium Acrylates/C10-30 Alkyl Acrylate Crosspolymer?
Sodium Acrylates/C10-30 Alkyl Acrylate Crosspolymer is a synthetic, high-molecular-weight polymer created through the copolymerization of acrylic acid and C10-30 alkyl acrylate monomers, then crosslinked into a three-dimensional network and neutralized with sodium. This structure enables it to absorb large amounts of water, swelling to form clear, viscous gels even at low use levels around 0.2-1%. In skincare products like serums, moisturizers, masks, and sunscreens, it serves as a rheology modifier, enhancing viscosity and flow properties for a smooth, elegant texture. It stabilizes emulsions by suspending oils and actives evenly, prevents phase separation, and deposits a flexible, non-occlusive film on the skin that improves product adhesion, water repellency, and aesthetic finish without tackiness or residue.
