The regular silicone products are made from food-grade silicone and are non-toxic and odorless. They have no effect on the human body. Because the silicone material itself has good adsorption properties, it easily absorbs the odor molecules in the surrounding environment. Sometimes, it is normal to smell a faint odor.
The newly manufactured silicone products may sometimes have a certain smell. This is usually some residual odors from the production process, not the actual smell of the silicone itself. During the molding of liquid silicone, the mold has to withstand high temperatures, eliminating all the odors from the material. In production, the most common method is to place it in a 200℃ oven to cure and allow the odors to dissipate. For silicone that meets food-grade standards, there are strict limitations on odors. So, there is no need to worry.
Under home conditions, if you boil it in boiling water, the odor molecules will be released and the smell will quickly disappear. You can also leave it in a well-ventilated area for two or three days, and the odor will naturally dissipate without affecting the quality of the silica gel product.
It should be noted, however, that some counterfeit or low-quality silicone products are often manufactured using industrial-grade silicone. Unscrupulous merchants, in order to make profits, use industrial silicone to pass off as food-grade silicone, which may pose a threat to health. These industrial-grade silicas do not have as strict control over volatile substances as food-grade ones, and often have a pungent smell. They can be easily distinguished by touch or by burning.
The composition and properties of silica gel:
Silica gel is a chemical material composed of silicon, with stable chemical properties. The main component of silica gel is silicon dioxide, which has stable chemical properties, is insoluble in water and any solvent, is non-toxic and odorless, and has no irritation to the human body. Generally, it does not cause allergies. In addition, silica gel products usually have good toughness, elasticity and smooth texture, while counterfeit silica gel products are prone to deformation and have a rough texture.
The safety of silicone products:
The safety of silicone products mainly depends on their composition and application. Food-grade silicone is a very safe material and is widely used in the food, medical, and other fields. For example, baby bottles, nipples, medical tubes, and other products usually use food-grade silicone. This type of silicone is non-toxic and harmless, and is also easy to clean.
The method for distinguishing genuine from fake silicone:
Feel: The genuine silicone product has a smooth texture and is not prone to deformation; while the counterfeit product has a rough texture and is easily deformed.
Burning test: Real silicone produces white smoke when burned, and the remaining substance after burning is white powder; counterfeit silicone produces black smoke when burned, and the remaining substance after burning is black powder.
Color: The genuine silicone has a bright and smooth color; the counterfeit silicone has a murky color and a rough texture.
Food-grade silicone usually has good elasticity, strong toughness and a smooth texture. However, industrial-grade silicone has poor elasticity and is prone to deformation. Food-grade silicone will not turn yellow when used for a long time. Industrial silicone, due to containing more impurities, is likely to turn yellow when exposed to ultraviolet rays. Of course, a more accurate method is to check if this product has relevant certifications. Regular food-grade silicone products usually have corresponding certification marks.
In summary, food-grade silicone is non-toxic, odorless, soft, has good elasticity, has a long service life, can withstand high-temperature disinfection, does not turn yellow at room temperature, does not spray frost, does not shed white substances, does not fade, does not form scale in water for a long time, and has no odor. It can demonstrate various advantages in fields such as mother and baby care and medical treatment.
