Applications of Propylene Glycol And Its Toxic Effects

Propylene glycol (PG) is a liquid chemical which is both odorless and colorless. It is used for a large variety of purposes. As it is considered non-toxic in small amounts, it is used in food addictives, cosmetics, pharmaceuticals and various industrial uses. However, the consumption of a large amount of this chemical liquid can cause serious medical complications such as seizures in humans. It can also cause liver and kidney damages in animals.

Different Applications of PG:

Food Addictives: It is widely used in food addictives as it helps to retain the moisture and absorb water. It is used in a wide range of beverages and dairy products as it keeps the food from freezing. This chemical liquid has the ability to dissolve dyes and food coloring. However, it is very important to note that a large amount of PG would result in several medical complications. People with allergic reactions should seldom consume food items and drinks which include this chemical liquid.

Animal Food: As this chemical liquid absorbs moisture, it is widely used in animal feed so that it remains fresh, chewy and moist. With the addition of this alcoholic chemical substance, animal food becomes soft and easy to digest. It also preserves the food for a longer period of time. It can be used in winters to prevent food items from freezing.

Cosmetic And Toiletries: Propylene glycol is among the most common additives used in majority of the cosmetics and toiletry products. It is used in lipsticks, deodorants and shower gels for enhancing its qualities. It enhances the foaming ability of the shower gels and improves the texture of lipsticks. It also prevents cosmetic products from freezing in low temperature and melting in high temperature. As the chemical is often used in small amounts, it seldom causes any harm except for people who have sensitive skin.

Industrial Uses: This chemical liquid is used for a variety of industrial applications. It is used for the production of polyester fiber in the textile industry. It is also used in commercial flights for de-icing purposes. This chemical is also used in liquid detergents.

As PG is neutral in nature, it is often used as a solvent carrier in most of the food items. It gives a unique appearance and taste to food items. It also helps to stabilize salad dressing, beer and pastries.

It is added in most of the dairy products to obtain the desired volume. This thickening agent is added in ice-creams, cheese and other products for the right consistency.

Health Risks Associated With PG:

Although propylene glycol includes a large number of uses in food additives and cosmetic products, recent studies have revealed its toxic effects too. This chemical also acts as a wetting agent which can easily penetrate the skin and cause skin rashes and blisters. Exposure to the chemical can affect the kidney, brain and liver according to recent surveys. However, this chemical liquid is banned for the use of cat food as it proves to be toxic.
