Here is what I know based on Secrist Doll Company studies...



There is no such thing as a 100% pure silicone doll. It has to be mixed with some sort of vinyl or rubber. Most are a vinyl/silicone mix. The problem is that the silicone leaches out from the vinyl over time and this can cause the paint to literally flake off from the doll.



Secrist promotes that their 100% vinyl doll will not have "flaking" problems over time and they will not change color (like silicone is prone too) as long as genesis heat-set paints are used on the reborned doll. Using oil paints on a silicone or vinyl doll will cause a bad reaction and the doll will eventually turn orange... sometimes this will happen as quickly year or so!



Whenever purchasing a doll that was manufactured in a country that doesn't have the quality control measures the U.S. has you need to be causious. Some countries put chemicals in their silicone/vinyl dolls that are actually outlawed in the U.S. because of safety concerns.



At least, this is what I have heard. You may need to contact the company directly to get any specifics you're looking for. Hope this helps...
