Silicone bakeware can release chemical compounds into food and air during baking, with children showing the highest modeled exposure.
“The results revealed that new silicone bakeware can emit and transfer measurable amounts of cyclic siloxanes during baking: Every product contained cyclic siloxanes, with twenty-five types (D3–D27) identified and quantifiable forms (D4–D16) totaling about 680 to 4,300 micrograms per gram of silicone.”
