The danger of desiccant, whether the desiccant is toxic

First of all, it is necessary to distinguish the type of desiccant, there are two common desiccant, which can be judged according to the form of the ingredients: one is quicklime desiccant, a white lump, which becomes a powder after being damp; The other is silica gel desiccant, which is colorless and transparent balls, and some are colored and look like delicious candy.

Situation 1: Ingestion of quicklime desiccant.

Drink water or milk immediately, but limit the amount of water you drink, 10 ml per kilogram of body weight, and the total amount should not exceed 200 ml, as excessive consumption may cause vomiting. Then he was sent to the hospital for **.

Situation 2: Ingestion of silica gel desiccant.

If you accidentally ingest this desiccant, you don't have to worry too much, because it cannot be absorbed in the gastrointestinal tract and can be excreted through feces, which is not toxic to the human body. No special treatment is required after ingestion. Unless there is a special reaction such as dizziness or vomiting, there is generally no need to seek medical attention.

What happens if the desiccant is eaten.

Eight-year-old because of an inadvertent move. The eyeball was completely dissolved, and he was blind for life. The well-behaved Doudou came home to find her mother buying a bunch of snacks and putting them on the table.

After Doudou finished the snack, he found a small packet of desiccant in the snack, so Doudou put the desiccant in the beverage bottle, and the drink bottle that was fried and deformed fell all over the ground.

There are two categories of desiccant: chemical adsorption and physical adsorption.

Chemical adsorption, such as concentrated sulfuric acid, quicklime, etc., has been in middle school physics, not to mention the harmfulness. In the early days, some appliances may have a small packet of quicklime in their packaging. It's also too dangerous, in case of a bear child. So they all became extinct later.

The common desiccant at home is physical adsorption, such as silica gel desiccant and clay desiccant.

The food packaging is generally a silica gel desiccant, which is said to be the only desiccant that has passed the US FDA certification and can be used in direct contact with food and medicine, so there is no need to worry about it being toxic.

Silica gel desiccant is very recognizable, smooth small particles, generally translucent, more particular with the addition of color-changing agent, once the moisture will become blue (purple).

As for clay desiccant, it is rare at home, grayish-brown, like soil grains. Due to its low cost, it is widely used in industry, such as the packaging of electronic products. This thing is also called montmorillonite or bentonite, so some people suddenly realized that some antidiarrheal drugs have montmorillonite.

This is also non-toxic, I have several drying ovens at home to store things that are afraid of moisture, both of which are available and can be reused after dehydration.

The most common desiccant of silica gel desiccant is made of silicate plus acid or ammonium salt, even if it is eaten in the stomach, there will be no serious consequences, because the stomach and intestines will not absorb this substance at all, and will finally be excreted with excrement. Calcium oxide desiccant is called quicklime, which is a lump with mostly white and off-white colors, it is more absorbent and very toxic.

Answer: This particulate silica gel desiccant is not toxic. Silica gel desiccant is a kind of base enzyme adsorption raw material, which is generally reflected with sodium metasilicate and hydrochloric acid, and prepared by a series of post-treatment methods such as embrittlement and acid bubble. Silicone rubber is an amorphous substance, and its chemical formula is.

It does not dissolve water and all organic solvents, is non-toxic and odorless, has stable physical properties, and does not reflect with all substances except strong acid and hydrochloric acid. The organic chemistry and physical structure of silicone rubber determine that it has many properties that cannot be replaced by other similar raw materials. Silica gel desiccant has high adsorption characteristics, good heat resistance, stable physical properties, high impact toughness, etc.

There is no problem with light smell, and there are many kinds of desiccant, but they are generally toxic (edible). to concentrated sulfuric acid. Sodium hydroxide and quicklime are corrosive, either acidic or alkaline, and can be harmful to the body.

Most of the desiccant in food is calcium chloride, which is inedible, but it is not very harmful to the human body. Old-fashioned phosphors can cause environmental pollution and harm to health, and now few people use them in China. Generally, a new type of environmentally friendly phosphor, such as the ultraviolet light-changing phosphor of gold dot plastic pigment, is non-toxic, harmless and environmentally friendly, and has been widely used in ink, printing and various industries, although harmless, but also inedible.

Food desiccants are non-toxic, but they are not edible.

Commonly used desiccants include silica gel desiccant, mineral desiccant, lime desiccant, calcium chloride desiccant; The moisture absorption rate of silica gel desiccant and mineral desiccant is close, although the moisture absorption rate of lime desiccant is high, it has certain danger and corrosiveness, and calcium chloride desiccant has the highest moisture absorption rate, but it has the shortcomings of moisture absorption, saturation and liquid state, and its use has limitations. Mineral desiccant is known as environmentally friendly desiccant, high quality and low price, and is selected by many export enterprises for product packaging.

The desiccant is non-toxic. Generally, the main ingredient of quicklime desiccant is calcium oxide, when calcium oxide meets water, a sharp chemical reaction will occur to generate calcium hydroxide, and a large amount of heat will be generated instantly, causing water to become water vapor.

Mineral desiccant contains diatomaceous earth, montmorillonite and other components, which is a porous mineral silicate, with a relatively large surface area and adsorption function for water, so it plays a drying role and is also non-toxic. The main raw material of silica gel desiccant silica is a kind of aqueous silica with high microporous structure, which is non-toxic, tasteless, odorless, chemically stable, has strong moisture absorption performance, and is a highly active adsorption material.

Problem description: Excuse me, usually in food packaging or other containers, there will be a packet of desiccant when you buy it back, may I ask, is this a group search for highly toxic? What should I do if my child doesn't know how to eat it by mistake? What are the dangers if ingested? Please elaborate, thank you!

Analysis: Many candies, biscuits or electrical appliances may be stored with desiccant in order to extend the life of the item. Occasionally, when some people eat, they swallow dates and accidentally eat the desiccant.

Sometimes it is the children of the family, curious to play, put them in their mouths and chew, at this time they can be anxious to the mother, and send the baby to the hospital.

Generally, there are four kinds of desiccant on the market, one is transparent silica gel, which is non-toxic and does not require any treatment. The other is coffee-colored ferric oxide, which is only slightly **, so that the person who eats it can dilute it with water, unless the patient deliberately takes a large amount of nausea, vomiting, abdominal pain, diarrhea, etc., the possibility of iron poisoning should be considered, and medical attention must be sought immediately. In addition, two kinds of white powder are leaked in the wild, one is calcium chloride, which is only slightly **, as long as you drink water to dilute it, the other is calcium oxide, which will become a strong alkali of calcium bicarbonate after encountering water, and it is rotten, please drink water at home to dilute it, and then send it to the hospital for further treatment.

For accidental ingestion of ferric oxide, calcium chloride and calcium oxide, it is necessary to drink water to dilute it at home, and the amount of drinking is subject to the patient's weight per kilogram 1, especially calcium oxide poisoning should not drink too much water, so as not to cause vomiting and easy to burn the esophagus again.

Summary. Hello, desiccant has dangerous goods and non-dangerous goods.

Hello, desiccant has dangerous goods and non-dangerous goods.

The function of desiccant is moisture-proof and hygroscopic, which will have an impact on the human body. So, it can be called dangerous goods. There are many types of desiccant, which are mainly divided into three types: food, industrial, and container transportation.

The desiccant used in food is non-toxic, the desiccant used in industry is slightly toxic, and the desiccant used in the damp-proof box is highly toxic, and people are inedible.

What about edible oxygen absorbers.

Non-toxic, not a dangerous good, but do not consume.

1. The harm of desiccant to the human body.

1. Burn the digestive tract.

General desiccant contains alkaline compounds, including calcium oxide, and calcium oxide will chemically react with the water in the body after entering the human body, and a large amount of heat will be generated in the process of reaction, which will inevitably burn the esophageal wall and stomach wall. The wall of the digestive tract is a very fragile organ, and once damaged, it is easy to cause lesions. Many esophageal cancers are caused by early esophageal burns that have not been cared for.

2. Cause blindness.

The alkaline chemicals in the food desiccant will cause great damage to the eyes, if accidentally splashed into the eyes, they will react with the liquid in the eyes, burn the eyeballs, and in severe cases, it can also lead to severe necrosis of the corneal conjunctiva.

Second, the treatment method of desiccant by mistake.

1. There is no need to be nervous when eating silica gel desiccant by mistake.

Some desiccants are made of silica gel, which does not undergo chemical reactions after entering the body, nor is it digested and absorbed, so there is no need to be nervous if you eat it, just wait for it to be excreted from the body on its own. However, if you feel unwell, please seek medical attention immediately, such as dizziness, nausea, and vomiting.

2. Drink water in time to dilute.

Some desiccants contain ferric oxide, which reacts with water in the body to produce iron, resulting in iron poisoning in the body. If you accidentally ingest this kind of desiccant, do not panic, and drink water or pure milk immediately, which can play a diluting role. After taking first aid measures on your own, you will go to a professional hospital for diagnosis and treatment.

Do not induce vomiting, as it can cause burns in the digestive tract, which outweighs the cost.
