[Glycerin and propylene glycol supply] Do you know about the glycerin and propylene glycol in e-cigarettes?

E-cigarette is an electronic product that imitates cigarettes and has the same characteristics as cigarettes. The look, smoke, taste and feel. It is a product that turns nicotine into steam through atomization and other means, allowing users to smoke it.

E-cigarettes produce a smoking effect by heating the e-cigarette liquid to form smoke. The main components of the e-cigarette liquid are nicotine, propylene glycol, glycerin and odorants. Let’s take you through the glycerin and propylene glycol:

Glycerin:

Glycerin, also known as glycerol, is colorless, odorless, sweet, and appears as a clear, viscous liquid. It is an organic substance. It can absorb moisture from the air, as well as hydrogen sulfide, hydrogen cyanide and sulfur dioxide. Insoluble in benzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ether and oil.

Food-grade glycerin is a sweetener and humectant commonly used in the food processing industry, and is mostly found in sports foods and milk replacers. Food-grade glycerin can be used as food additives. It is qualified in terms of purity, color, and heavy metal content, and comes with an inspection and quarantine health certificate for the corresponding batch. Food-grade glycerol must be certified by the China Food Hygiene Inspection Bureau and be deemed to comply with the “Food Safety Standard Food Additive Consumption Standard” (GB2760 standard).

The entry threshold for electronic cigarette oil factories is too low, resulting in uneven quality of glycerin used. When the impurities contained in glycerin are relatively high, these impurities will either accumulate on the heating wire to form deposits, or enter the lungs with the steam. After entering the lungs, they may irritate the bronchial mucosa or even stay in the bronchial mucosa. This stimulation is similar to the impact of PM2.5, but it is additive. This is the reason why many people feel itchy throats after using e-cigarettes. There must be some harm, but the extent is difficult to estimate. If the purity of glycerin itself is high enough, it will not have adverse reactions on a healthy human body. After a large amount of glycerol enters the human body, it is possible to increase blood sugar in the human body, so people with high blood sugar and diabetes should not use e-cigarettes!

Propylene glycol:

Propylene glycol is an organic Compound (diol), usually a slightly sweet, odorless, colorless and transparent oily liquid, absorbs moisture and is easily mixed with water, acetone, and chloroform. It is widely used in the food, pharmaceutical and cosmetic industries. In the application of food-grade propylene glycol, in flavors, fragrances, and baked pastries, propylene glycol is an extremely excellent raw material and has an irreplaceable position in the production of many products.

Food-grade propylene glycol has clear dosage requirements, and manufacturers are required to have a food additive (propylene glycol) production license. Imported food-grade propylene glycol requires suppliers to provide Inspection and quarantine certificate corresponding to the batch of propylene glycol.

Propylene glycol is used as a flavor dissolving agent in e-liquid. Glycerin is too viscous, making it difficult to dissolve flavors, so propylene glycol, which is miscible with glycerin and flavors, becomes the dissolution medium. Propylene glycol is widely used in the industry as antifreeze, humidifiers and food additives. However, because inhaling large amounts of propylene glycol can cause irritation to the respiratory tract (a bit like the throat hit of nicotine), opponents believe that propylene glycol may be harmful. However, as a liquid, propylene glycol can volatilize with the respiratory system, so the long-term effects of this intermittent stimulation and then volatilization are not conclusive in the medical community.
