Polyalcohol content

Commercial lithopone grades contain 30% ZnS (red seal) and 60% ZnS (silver seal). The ZnS content of Sachtolith is > 97 %. Various chemical (e.g., polyalcohols, siloxanes, silanes) and mechanical treatments (e.g., jet milling) are used to obtain other products for special applications. The technical data for commercial red seal lithopone and Sachtolith are given in Table 20.

Sometimes our method helped the pharmaceutical technicians to modify the formula of the excipients and stabilize the water content. They could also better understand the as-yet-unknown behavior of certain additives like heavy polyalcohols, glycerol, or tensioactive agents. 

Certain organic samples such as lower molecular weight alcohols, polyalcohols, organic acids, organometallic salts, amines and esters in either aliphatic or aromatic form can be analysed directly or after dilution in a suitable ICP-AES compatible solvent. These samples can be analysed for formulated or contaminated metals against a calibration curve prepared from a certified stock standard in the same solvent. Organic samples with varying viscosities, particularly for trace metals content, may be... 

Sorbitol is another polyalcohol which has been condensed with nicotinic acid to furnish sorbitol hexanicotinate (VI). This ester was found to possess hypolipidemic activity in h5 ercholesterolemic experimental animals [60]. The intramuscular injection of 2-diethylaminoethyl nicotinate (VII) produced a significant reduction in the free fatty acid content of plasma in man [61].
