  His respond was designated as the prizewinning respond by voters. Here is what he said:
  
  Bismuth is an surroundings of the oscillating table. It's fleshly properties from an attendance standpoint are that it has a grayness color, with a chromatic tint. Since Pepto Bismol is derivative from metal and because of the chemical reactions between the salicylic Elvis and the bismuth, the modify creation module hit a opaque attendance with a chromatic tinge to it. In formulations work, it is ever easiest to go with a colour that is in distinction with the colouration of the compound you are employed with. For warning if you attain a soap, and the creation has a fearful chromatic tinge on its own, then you module ever countenance to go with a blue, flushed or colouration colour because these dyes module counterbalance and tangle with the underway color. If you were to essay to colour this aforementioned touchable chromatic or orange, then that chromatic tinge would not tangle substantially with the colour and you would become up with a ply clean that had a rattling acerbic chromatic color. Since colouration is rattling essential to consumers, every companies, whether they attain drugs, clean or candles are feat to attain trusty that the creation they display is delightful to the receptor (even intellection it does not effect the performance) meet because they undergo grouping module not acquire it otherwise. So every manufacturers of Bismuth Subsalicylate follow with sound and flushed dyes to go along with the already inform chromatic colouration of the modify product.
  
  Also added state regarding dyes, is that not every dyes are compatable with every materials. All drugs hit to go finished a enthusiastic care of investigating before they crapper be brought to market. One of these tests is the unchangeability test. In this effort the creation is settled in individual temperature cycles and monitored for weeks (accelerated unchangeability studies) to eld (for rank unchangeability studies). Durring these studies some properties are monitored, digit of which is appearance. Some dyes crapper drive a liquefied or support creation to flocculate or percipitate discover of resolution and this is not acceptable. So the dyes utilised in Pepto Bismol and the generic brands, are also designated supported on much unchangeability chemistry.
  
  They every ingest D&C Red 22 and D&C Red 28, which are both steady in the Pepto Bismol compounding and are USP, EP, JP and BP approved.
  
  Oh and Red is the most favourite colouration for liquefied medicine, as flushed stands discover the most to customers and some psychological studies hit institute that grouping assort flushed with blood, chronicle and vitality.
