  • Applications

    O-palmitoyl pullulan is a palmitoyl-modified polysaccharide used in cosmetics and personal care as a film-forming polymer, emollient, and thickener/rheology modifier, and it may serve as a carrier for active ingredients and as an emulsion stabilizer in topical formulations. In coatings and inks, it can function as a binder or film-forming component to improve film integrity and surface adhesion. In polymers and plastics, it may act as a property modifier or a compatibilizer between hydrophilic and hydrophobic phases. In adhesives, it can serve as a binder or film-forming additive. In household cleaning products, it can act as a thickener and rheology modifier for cleaning solutions.
