FLEXAN® II Polymer 

INCI Name:

Sodium Polystyrene Sulfonate

FLEXAN® II polymer is a high molecular weight polystyrene sulfonate, sodium salt supplied as a free flowing off-white powder. FLEXAN® II polymer 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. For hair care, it can be used to remove cationic build-up on hair, making it ideal for shampoos and cleansing products. FLEXAN® II polymer's water soluble polymer films are strong and flexible, making it a multifunctional ingredient for various styling aids. For skin care, its film forming properties tighten skin and smooth fine lines and wrinkles.
