Monosodium phosphate (MP), sodium citrate (SC), sodium lactate (SL) and magnesium citrate (MC) can be blended with hydroxypropyl methylcellulose (HPMC) to make photophobic (white) films at lower drying temperatures. Small angle X-ray scattering (SAXS), wide angle X-ray diffraction (XRD), scanning electron microscopy (SEM), whiteness determination, dynamic mechanical analysis (DMA) and texture analysis were adopted to study the variation of microstructures and properties. These four kinds of...
