Diluents magnesium carbonate

Ultraviolet and Visible Spectra. All solution spectra were scanned in the visible and ultraviolet regions on a Bausch and Lomb Model 505 Spectrophotometer. Refiectance spectra were obtained with a Beckman DU Spectrophotometer equipped with the Beckman 2580 reflectance attachment. Magnesium carbonate used as a reference and diluent were... 

Calcium carbonate, calcium sulfate, kaolin, talc, magnesium carbonate, and zinc oxide are frequently used as nutrient supplements or food diluents. Calcium silicate and fumed silica are used as anticaking agents. They are added in concen-... 

Patel et al. [40] found that moismre and the pH of the micro-environment influenced degradation the most. They identified the best diluent for tablet manufacture as being dibasic calcium phosphate, with a basic modifier (sodium carbonate, sodium bicarbonate or magnesium oxide). The authors indicated that the degradation pathways observed were deiodination, deamination and decarboxylation. The data are shown in Table 2.4. 

Manufacture of HGC dosage forms compared with tablets requires minimum formulation efforts and usually involves granulation of the API powders with diluents such as lactose, mannitol, calcium carbonate, and lubricants such as magnesium stearate. Prior to filling the capsules with the granulated API powder, the body and cap are separated. The cap is replaced after completion of the filling...
