Hi Smytrous,
Not that I’m aware of no although if you are one of the very few people that have a type I latex allergy (the type of allergy where you would need to carry an epipen) I would avoid anything that may contain any natural latex of any type in your environment (see post #2 here).
All the latex you are likely to encounter (whether it is Dunlop or Talalay and made with natural or synthetic rubber or a blend of both) would all be tested by either Oeko-Tex or Eco-Institut using the same testing protocol for harmful substances and VOC’s and I would consider all of them to be equally “safe” (see post #2 here).
