Whether desiccant is harmful to human body depends on the type of desiccant, there are six common desiccants in life, including lime desiccant, silica gel desiccant, montmorillonite desiccant and calcium chloride desiccant, molecular sieve desiccant, fiber desiccant, etc. 1, lime desiccant: this desiccant is a white block, but it will become powder after being damp, which is harmful to human body. It should be noted that if accidentally eaten by mistake, remember not to vomit, you can drink milk or water. At the same time, do not use any acid to neutralize the desiccant, because the neutralization reaction may occur, and the heat released will aggravate the disease; 2.Silica gel desiccant: usually silica gel is colorless and transparent spherical, of course, there is also colored silica gel, if accidentally eaten, there is no need to worry especially, because in general, silica gel will not be absorbed in the gastrointestinal tract, and will be discharged with feces, so it will not be toxic to human body; 3.Montmorillonite Desiccant: usually no harm to the human body, is a tasteless and non-polluting desiccant, if inadvertently taken, you can drink more water to promote the substance out of the body, do not have to worry about special. Generally, montmorillonite desiccant is used for food packaging, medical health care, etc.; 4, calcium chloride desiccant: usually brief contact with calcium chloride desiccant will not be harmful to the body, but if it is taken carelessly or used for a long time, it will still harm the health, so it is not recommended to use the desiccant for a long time; 5, molecular sieve desiccant: it is a synthetic and strong adsorption desiccant for water molecules, which is safer and Non-toxic; 6.Fiber desiccant: it is made of pure natural plant fiber refined by special process, safe and non-toxic, generally not harmful to human body. If there is desiccant splashed into eyes, you can use saline or water to rinse from the side of nose to the side of ear as soon as possible, at least 15 minutes for each rinse, and serious patients should be sent to hospital as soon as possible for consultation and treatment.
