Flexan II polymer is a high molecular weight polystyrene sulfonate, sodium salt supplied as a free flowing off-white powder. It is a highly versatile polymer that provides benefits in both hair and skin care products. It forms clear, flexible films that shrink upon drying, quickly dissipates electric charge, is stable to temperatures exceeding 300°C, is highly anionic, and helps to reduce surface tension. In styling aids, Flexan II polymer is ideal for thermal protection and curl enhancing products. Flexan II polymer's water soluble polymer films are strong and flexible, making it a multifunctional ingredient for various styling aids.
