Propylene glycol is a colorless organic liquid. Its chemical name is 'Propane-1,2' with the formula C3H8O2. The CAS registry number is 57-55-6. Common names are propylene glycol (PG) and monopropylene glycol (MPG). Propylene glycol can be manufactured in different qualities. The most controlled grade is called propylene glycol-USP / EP and is manufactured and distributed according to the high standards of the industry. The normal grade PG is called industrial grade. Both grades can be commercially available under different trade names.
Propylene glycol or more commonly known as propylene glycol used in e-cigarettes, is a colorless and sweet liquid with a thick and sticky texture. Propylene glycol is used in the production of food and cosmetics, it is safe for humans and environmentally friendly.
It is the substance that helps to dissolve the flavoring substances contained in the e-cigarette and with the help of heat provides the vapor that resembles cigarette smoke.
Propylene glycol is used in a wide variety of everyday convenience and care products, such as in cosmetics and personal care products, food, animal feed, and pharmaceuticals, as well as in various industrial applications.
Most consumers come into contact with propylene glycol in their normal daily lives, when they use personal care products such as creams, sprays, lotions, when they enjoy soft drinks, sweets and other foods, or when they take a medication or are vaccinated against a serious disease.
Propylene glycol is used professionally by manufacturers of consumer and industrial products, but it is not available to consumers as a pure substance. Under normal conditions, therefore, it is impossible to ingest large quantities of propylene glycol, as consumers' exposure to propylene glycol through products is extremely low. Furthermore, studies have shown that propylene glycol has a very low degree of toxicity.
In fact, from a toxicological point of view, alcohol is more toxic than propylene glycol. European legislation limits the presence of propylene glycol as a food additive to 1-3 g / kg in the final food (0.1-0.3%). A complete acceptable daily intake (ADI) of 0-25 mg / kg body weight has been assigned to propylene glycol by the European Commission's Scientific Committee on Food.
Propylene glycol has been safely used for more than 50 years in a wide variety of applications. Studies have shown that propylene glycol has a very low degree of toxicity. No negative health effects from exposure to small amounts of propylene glycol have ever been observed. Authorities have approved the use of propylene glycol in sensitive applications such as pharmaceuticals, food and cosmetics, and thus confirmed its safety.
