Binders sodium carboxymethyl cellulose

Sodium carboxymethyl cellulose is an anionic water-soluble polymer and is widely used in oral and topical pharmaceutical formulations because of its viscosity-increasing properties. Viscous aqueous solutions are used to suspend powders intended for topical, oral, or parenteral applications [13]. It is also used as a tablet binder and to stabilize emulsions [14]. 

Sodium carboxymethyl cellulose SCMC is a low-cost, soluble, and polyanionic polysaccharide derivative of cellulose that has been employed in medicine as an emulsifying agent in pharmaceuticals and in cosmetics. The many important functions provided by this polymer make it a preferred thickener, suspending aid, stabilizer, binder, and film-former in a wide variety of nses. In biomedicine, it has been anployed for preventing postsurgical soft tissue and epidural scar adhesions.

It should also be noted that attention should be taken to the fact that the performance of SiO-anodes depend importantly on the choice of binder, which makes difficult the quantitative comparison of the electrochemical performance between different works. The study of the electrochemical properties for different binders has been made by Komaba et al. [423] who showed that the electrochemical reversibility of SiO anodes is drastically improved by using polyfacrylic acid) (PAA) as the binder in comparison to the PVdF, sodium carboxymethyl cellulose (NaCMC), and polyfvinyl alcohol) PVA hinders. Polyimide as hinder was also found to give very good results [424], A concern with SiO is the thermal instahility due to the sudden exothermic peak in the region of 350-400 °C. This enthalpy peak, however, is importantly reduced (hut not suppressed) hy coating SiO with anatase TiOa [425]. This has been attributed to the thermal stability of lithiated Ti02 and its SEI [279, 280]. 

Natural convectional dryer has been used in Philippines to produce dried sweet potato. These dryers utilize heat from burning the wastes. About 50 kg of sweet potato chips of high quality are dried for 7-8 h. Another form in which sweet potato is dried and eaten as a dessert or snack is as an edible leather also known as fruit roll or crush. In this preparation, the flesh of sweet potato is cooked, mashed, and sieved, mixed with 0.5% (w/w) carboxymethyl cellulose (a binder), 200 ppm sodium bisulfite, and 7% (w/w) sugar and formed into a sheet 1-mm thick, which is oven-dried at 55°C-75°C and I0%-17% moisture level. Samples dried at 75°C were chewier than those dried at lower temperatures. Samples were crisper and crunchier when dried at 55°C or 65°C. A laboratory-scale high-temperature short-time (HTST)... 

Binders which are soluble in nutritional inks are in particular cellulose derivatives, such as hydroxypropyl cellulose, hydroxymethyl propyl cellulose or sodium salts of carboxymethyl cellulose, polyvinylpyrrolidone.
