Health product desiccant What are the considerations for choosing them? There are reports that a student caused a thermos to explode and suffered near blindness after putting a desiccant packet from seaweed snacks into a thermos. This has raised concerns about desiccants Many foods and medicines now contain desiccants. According to Hengyuan Desiccants, silica gel desiccants are currently the most commonly used and are relatively safe. The type that caused the explosion was quicklime desiccant, which poses certain safety hazards.

　　Hengyuan Desiccants explains that the main component of this desiccant is calcium oxide (quicklime), which, upon absorbing water, becomes calcium hydroxide, releasing a large amount of heat in the process. When the air expands rapidly, an explosion can occur.

　　Reporters learned that a desiccant is a dehydrating agent that absorbs moisture from the atmosphere. Hengyuan Desiccants' Shen Gong stated that silica gel desiccants are currently commonly used in food and pharmaceuticals. Its main component is silicon dioxide, a highly active adsorption material. Silica gel desiccant is also the only desiccant approved by the U.S. FDA for direct contact with food and pharmaceuticals. If ingested by mistake, it will not harm the human body, nor will it be absorbed by the body; it can be excreted through feces.

　　Shen Gong introduced that quicklime desiccants is still used by some companies due to its lower cost, but this desiccant is corrosive and has been largely replaced by silica gel desiccants. Shen Gong also suggested that if you want to buy health product desiccants, it is recommended to purchase them from a regular manufacturer; general desiccant manufacturers do not have the relevant qualifications. Hengyuan's fiber desiccants do not have these safety hazards and are a very good choice.
