Estimating the term…
The present invention relates to a composition comprising: (a) at least one thiopyridinone compound; and (b) at least one fatty acid comprising 18 or more carbon atoms, wherein the amount of the (b) fatty acid(s) comprising 18 or more carbon atoms in the composition is 10% by weight or more, preferably 12% by weight or more, and more preferably 14% by weight or more, relative to the total weight of the composition. The present invention can provide a composition including (a) thiopyridinone compound(s) with increased stability of the (a) thiopyridinone compound(s) over time, in particular even when the composition is maintained for a relatively long period of time under elevated temperature, and with reduced yellowing just after adding the thiopyridinone compound to the composition.
A composition, comprising:
A method for stabilizing (a) a compound being N-[(2-thioxo-1,2-dihydropyridin-3-yl)carbonyl]glycine, a salt thereof, a solvate thereof, an optical isomer thereof, or a racemate thereof and reducing yellowing of a composition containing the (a) compound being N-[(2-thioxo-1, 2-dihydropyridin-3-yl) carbonyl] glycine, the salt thereof, the solvate thereof, the optical isomer thereof, or the racemate thereof, comprising:
