Monodisperse glycogen or phytoglycogen nanoparticles are polyfunctional additives suitable for use in aqueous or alcohol-based cosmetic, pharmaceutical, or food formulations. The nanoparticles may be isolated from various sources (such as corn), and are optionally modified with a range of organic moieties (such as octenyl succinic acid). The monodisperse and particulate nature of the glycogen/phytoglycogen is believed to render such materials useful as rheological modifiers (including modulation of thixotropic behaviour), stabilizers of organic and biological materials, and photostabilizers in sunscreens. |
