A new study on silicone bakeware has found that when baked at high temperatures, chemicals known as cyclic siloxanes can leach into food and the air. These siloxanes are classified from D4 to D16 based on molecular size, with smaller ones potentially evaporating into the air and larger ones remaining in the food. While some studies have suggested possible health risks associated with these chemicals, such as endocrine disruption and liver toxicity, experts advise against panicking and throwing away silicone bakeware.

The study found that chemical migration decreased significantly after repeated use of the silicone baking tools, indicating that they may become safer over time. Experts recommend those who are concerned about the potential risks to consider using alternative materials such as glass or parchment paper for baking. Overall, while silicone bakeware may release chemicals during baking, the levels dissipate quickly in the air, and with prolonged use, the amount of chemicals released decreases, making continued use of silicone bakeware a viable option for many consumers.
