Is glycerol harmful to the human body? Introduction to the role of glycerol in electronic cigarettes

Is glycerol harmful to the human body? Many friends may not have heard of the name glycerol because it is a chemical name, but if it is called glycerol, some friends will know it. This thing is also quite common, and perhaps people do not pay attention to the material list of food. In fact, many food material lists can see its figure.

Is glycerol harmful to the human body?
Glycerol, also known as glycerol, has a wide range of applications and is commonly found in industries such as medicine, food, daily chemicals, textiles, paper making, and paint. Glycerol is found in the tobacco oil of electronic cigarettes.
The harm of glycerol to humans also depends on its dosage. The LD50 of glycerol to rats is>20ml/kg, which is approximately 25g/kg (orally). It's okay for a person to take 100 grams orally, as this dosage is considered non-toxic in toxicology. In fact, the human body consumes glycerol every day, and one of the hydrolysates of fat consumed in the digestive system is glycerol, which is absorbed by the small intestine and is a very important nutrient.
Toxicological data of glycerol:
Toxicity classification: Poisoning
Acute toxicity: oral LD50 in rats: 26000 mg/kg; Oral - mouse LC50: 4090 mg/kg.
Irritation data: Skin rabbit 500 mg/24 hours mild; Eyes - Rabbit 126 milligrams mild.
Eating is non-toxic to the human body. When used as a solvent, it can be oxidized to acrolein, which is irritating. The LC50 for intravenous injection into mice is 7.56g/kg, and the maximum allowable concentration in the workplace is 10mg/m3.
Rat oral LD50: 20ml/kg; Intravenous injection of LD50: 4.4ml/kg. Store in a cool and dry place.
The use of glycerol:
1. Glycerol also plays a role in the food industry as a sweetener, a moisture absorbent for tobacco agents, and a solvent.
2. Glycerol can be used in the coating industry to produce various alkyd resins, polyester resins, glycidyl ethers, epoxy resins, and other items.
3. Glycerol can be dissolved in any ratio with water, and low concentration glycerol solution can be used as a lubricating oil, which has a moisturizing effect on the skin.
4. Glycerol can be used for the analysis of aqueous solutions, solvents, gas meters, and hydraulic press cushioning fluids, softeners, desiccants, lubricants, cosmetic formulations, organic synthesis, plasticizers, and more.
The role of glycerol in electronic cigarettes:
Glycerol mainly plays a smoke role in electronic cigarettes. The higher the concentration of glycerol, the thicker and larger the smoke produced by the tobacco oil. Generally speaking, due to the presence of glycerol, tobacco oil tends to be slightly sweet. I hope friends will pay attention to this.
If the purity of glycerol itself is high enough, it will basically not produce adverse reactions to the healthy human body. It should be noted that a large amount of glycerol entering the human body will lead to the possibility of high blood sugar, so people with high blood sugar and diabetes had better not use electronic cigarettes! In addition, when choosing glycerol, it is important to try to choose one with better quality.
In summary, glycerol is not harmful to the human body, and this is within the safe dosage range. Many foods, such as cakes and bread, also add a certain amount of food grade glycerol as a water retaining and moisturizing agent, so glycerol is very common in daily life. Electronic cigarettes also add a certain amount of glycerol, mainly for smoke.
