Latex

The production of latex involves the use of nitrosamines and their precursors, which are known to be potent cancer-causing substances. These chemicals are added to increase the strength and elasticity of the final product, such as rubber nipples on baby bottles. Unfortunately, wear and tear can cause rubber nipples to release nitrosamines and their precursors as a baby suckles. Studies show that the precursors actually transform into nitrosamines when they are exposed to saliva.
