One oxygen atom can make a lot of difference sometimes. For example carbon monoxide and carbon dioxide -- one is vital for life and the other a deadly poison.
However, this doesn't explain the difference in regulation between MSM and DMSO. I believe DMSO can be quite dangerous because of its ability to transport substances through the skin. Some chemists working with insecticides got seriously poisoned when some insecticide dissolved in DMSO got on their hands. If you use it, both your hands and the area you are applying it to must be clean and it must be uncontaminated. Anyway, no idea about regulations. I am a chemist not a politician. CE stands for (in this case) chemical engineering, but of course CE is also the European equivalent of the FCC.
