WebReactivity Profile. POLYETHYLENE GLYCOL 200 is heat-stable and inert to many chemical agents; it will not hydrolyze or deteriorate under normal conditions. This material has a solvent action on some plastics. (NTP, 1992) WebThe drug's solubility could be altered noticeably by the change of both χ and polymer molecular weight. The study also suggests that the depression of drug's melting point is a good indicator for preliminary polymer screening. The polymer that reduces the melting point the most is likely to be most miscible with the drug. mcdonald\u0027s scrambled eggs nutrition
