Observant people will find that silicone products are widely present in our lives. When we mention silicone, we may first think of chemical raw materials used in industry. Some of the silicone products we use around us are related to our tableware. So, is silicone harmful to the human body

Let's start with the composition of liquid silicone, which is the raw material for making silicone products. Two component liquid silicone is composed of AB and AB components. When AB and AB components are mixed in a certain proportion, cross-linking and curing reactions can occur to form a soft elastic material.
Liquid silicone raw materials are generally composed of five components: base gel, crosslinking agent, catalyst, filler, and additives.
In theory, as long as there are the first three components, mold silicone can be made, but in order to obtain a certain strength, "fillers" are generally necessary, and "additives" depend on the situation.
Usually, the base gel, crosslinking agent, and filler are made into one component, while the catalyst is made into a separate component.
The ratio of catalyst component to main gel component is generally between 1% and 3%, and the rate of the gel reaction can be adjusted by adjusting the catalyst ratio.

In addition, silicon is a chemical element and the most abundant element in the Earth's crust.
Its compounds normally consist of sand, rock layers, and glass.
Organosilicon is considered the most suitable material for implantation in the human body, and all human bodies contain some organosilicon.
Organosilicon is widely used in fields such as medical devices, pharmaceuticals, and food.
Silicone itself is not toxic, but some silicone contains harmful additives to the human body. The main component of silicone is silicon dioxide, which has stable chemical properties and is non-toxic.
Silicone has strong adsorption capacity and can have a drying effect on human skin.

Therefore, we can conclude that silicone rubber itself is non-toxic and harmless, as long as no pigments are added. Silicone gel with platinum curing agent can achieve food grade.
