Styrene/Dvb Crosspolymer

What is Styrene/Dvb Crosspolymer?

Styrene/DVB Crosspolymer is a synthetic, cross-linked polymer created by copolymerizing styrene with divinylbenzene through emulsion or suspension polymerization processes. This results in rigid, spherical microbeads typically ranging from 1 to 50 micrometers in size. In cosmetics, it appears in makeup foundations, sunscreens, shampoos, and lotions within the color cosmetics, sun care, and hair styling categories. Functionally, it deposits as a flexible, continuous film on skin or hair surfaces, boosting adhesion, water repellency, and durability against smudging. Its light-diffusing particles scatter light to impart opacity, transforming clear or translucent formulas into smooth, creamy textures while concealing minor imperfections or undissolved components for a polished finish.
