ABSTRACT
New trends in food packaging are using polymers in intelligent packaging (using nanosensors), delivery and controlled release of neutraceuticals, antibacterial agents, self-cleaning packaging, and systems to monitor product conditions during transportation [2, 3]. In cosmetics, they provide excellent water resistance and can be used to protect water-sensitive ingredients. They can be used as film formers, fixatives, rheology modifiers, emulsifiers, stimuli-responsive agents, conditioners, foam stabilizers and destabilizers, skin-feel beneficial agents, and antimicrobials [4].Advances in controlled-release technology in recent years have been possible as a result of advances in polymer science that allow the fabrication of polymers with tailor-made specifications, such as molecular size, charge density, hydrophobicity, specific functional groups, biocompatibility and degradability [5].
