Is caulking silicone toxic?
Silicone caulking is non-toxic and highly tolerable once cured.
Many experts and authorities consider silicone completely safe for food use. For example Health Canada states: "There are no known health hazards associated with use of silicone cookware. Silicone rubber does not react with food or beverages, or produce any hazardous fumes."
Shellac, derived from Indian lac bugs, is a common food-safe film finish. It is highly water-resistant. Available in different hues, shellac is sold in liquid form or in flakes that must be dissolved in ethanol before application. (The ethanol evaporates during the curing process.)
Silicone caulk is excellent at water sealing and flexibility so it has its place in construction. There are two main places it never should be installed, wood or any painted surface.
Silicone can cause breakouts, irritations, and acne
It can especially cause irritations for people who have sensitive skin and cause your skin to become even more sensitive. If you are acne-prone and oily, using silicone-based products will make it even worse.
Is silicone safe for food? Food-grade silicone is safe to store food, put in the microwave, freezer, oven, and dishwasher, as it's made without petroleum-based chemicals, BPA, BPS, or fillers. You can even cook right in your Minimal silicone food container, sous vide style.
FDA-approved food- grade silicone can withstand temperatures from -80°F to 450°F. Silicone maintains its integrity at high temperatures, and it remains flexible at low temperatures. Flexibility: The food processing industry is one of the most demanding industries in terms of hygiene and mechanics.
Using food-grade silicone with certain foods or ingredients can stain the material, sometimes permanently.

Is DAP silicone sealant food safe?
Safe for incidental food contact. Dishwasher and microwave safe. Also ideal for building or repairing aquariums. Harmless to fresh and saltwater fish when cured.
Silicone Sealant Limitations
Possibility of surface dirt retention due to static charge. Not successfully paintable (in general for high quality silicones) Primers may be required on some surfaces. Lower tear and abrasion resistance.
High-Purity Silicone Sealant, RTV curing. Safe for fish or Drinking Water and Continuous Submersion. UV Safe. Non-sagging.
Silicone is very flexible and acts as a water and moisture repellant, making it among the best caulks for both windows and bathrooms. It is more expensive than latex caulk, but it is highly durable. Silicone caulk stands up to extremes in temperature changes and can last up to 20 years when properly applied.
Silicone rubber cured or un-cured is not considered as hazardous waste and therefore can be disposed of in accordance with the local regulations regarding waste disposal.
The argument: They cause breakouts
Sure, they keep environmental aggressors out, but they also lock in some not-so-great substances. “For acne-prone patients, silicones can act as a 'barrier' and trap oil, dirt, and dead skin cells, making acne worse,” Mraz Robinson says.
