Sodium Acrylates/Beheneth-25 Methacrylate Crosspolymer

What Sodium Acrylates/Beheneth-25 Methacrylate Crosspolymer is & what it does

Sodium Acrylates/Beheneth-25 Methacrylate Crosspolymer is a synthetic crosslinked polymer made from acrylate and methacrylate building blocks. In skincare and sunscreen formulas it acts as a thickener and rheology modifier, helping to build viscosity and stabilize emulsions so the product has a smooth, consistent texture. A notable property is that, because it carries both water-loving and oil-loving parts, it can also help structure formulas that combine water and oil phases.
