About

A hybrid polymer blend combining PEI (polyethylenimine) with pullulan acetate, used in cosmetic films and tightening formulations for an immediate skin-lifting effect.

PEI-42 Pullulan Acetate is a combination of low-molecular-weight polyethylenimine (PEI-42) crosslinked or combined with pullulan acetate, a naturally derived polysaccharide from Aureobasidium pullulans. The combination creates a film-forming complex used for immediate skin-tightening and smoothing effects in cosmetics. PEI is known for good film-forming properties, while pullulan provides flexibility and moisture resistance. The compound is listed in EU CosIng without restrictions. No significant safety concerns at cosmetic use levels.
