Tylose or Gum tragacanth?

Hi, I don’t necessarily have the correct answer but I know that when adding them to sugarpaste for modelling purposes gum tragacanth is a natural ingredient and once added should be left over night to work where as when tylose/CMC is added it takes effect straight away so can be used immediately. I’m guessing that it works the same with mmf?

Tylose is the synthetic version on Gum Trag, i’ve never used it with mmf but i use them for petal paste, which hardens it like plaster =D.
