Herein the optical properties of Hydroxypropyl methylcellulose/Potassium iodide (HPMC/KI) composite films were determined. The casting technique was introduced to make HPMC/KI with different KI salt concentrations (0.1–1) wt%. absorbance model used determine parameters like absorption edge, refractive index, real and imaginary sections dielectric function, extinction coefficient, Urbach energy,...

The mango is the most widely cultivated tropical fruit. Fresh-cut very useful, but it perishable. purpose of this study was to highlight effects neem oil on fresh-cut fruits kept for 9 days at 4 ± 1 °C and 80 5% relative humidity. plant (Azadirachta indica) has numerous antioxidant antibacterial properties. Despite this, few studies have been carried out added edible coatings (EC) retard ripeni...

The purpose of this study was formulation and in vitro evaluation of floating-bioadhesive tablets to lengthen the stay of glipizide in its absorption area. Effervescent tablets were made using chitosan (CH), hydroxypropyl methylcellulose (HPMC), carbopolP934 (CP), polymethacrylic acid (PMA), citric acid, and sodium bicarbonate. Tablets with 5% effervescent base had longer lag time than 10%. The...

A novel method for preparing eco-biodegradable lubricant based on hydroxypropyl methylcellulose (HPMC) via hydration process is demonstrated. The smooth and homogeneous HPMC coating has a uniform thickness (~35 μm). It has been demonstrated that the preparation parameters play a critical role in controlling the lubricating behavior of the coating; in addition, excess HPMC and water concentratio...
