Propylene glycol: Uses - Definition

Propylene glycol

Propylene glycol (CHO), also may be called (Propane-1,2-diol), is a synthetic liquid used in the production of many industries. It is a viscous, colorless, almost odorless, sweet-tasting liquid. Propylene glycol is mixed with water in different concentrations, to lower its freezing point and keep it as a liquid for a longer period, and this is important in some industries and uses. Propylene glycol can present some environmental concerns.[1]

 

 

Propylene glycol uses

The following are the most important industries in which propylene glycol is used:[2]

 

 

Pharmaceutical industry

Propylene glycol is used to dissolve other substances, which are usually solid, without changing their basic structure or composition, and is used to dilute and stabilize medicines, and propylene glycol is used in the formation of various forms of medicines including oral medicines such as capsules and tablets, or topical medicines such as creams and gels Medicines are administered intravenously, i.e. by injection.[2]

 

 

Cosmetic industry

Propylene glycol is a common ingredient in cosmetics, personal care and skin products, and propylene glycol is a versatile substance that performs many functions when added to cosmetic products. The most important of these uses are:[2][3]

 

1.      The manufacture of humectants, which are cosmetics and skin care products for their ability to moisturize, and propylene glycol acts as a humectant by attracting moisture to the skin.

2.     Propylene glycol is used as a solvent. The compound is used to dissolve the substances in the product formulation to make them mix and work together properly.

3.     Emollient industry: Propylene glycol is used as an emollient because it forms a greasy film on the skin and prevents water loss.

4.     Viscosity control: Propylene glycol is used to reduce the thickness of cosmetic products and cosmetics, improving the absorption quality of the products.

5.     Porcelain glycol is often used with other chemicals as a preservative in cosmetics and skin care products.

 

 

Food industry

Propylene glycol is used in the production of many different foods, the most important of which are ice cream, drinks, and various types of bread, due to its ability to retain moisture and because of its sweet taste. Also as carriers of flavors, fragrances, vitamins and food dyes.[3]

 

 

Anti-freeze

Propylene glycol is used as antifreeze, and is a large part of aircraft dismantling equipment, and is used to defrost airport runways, and because it is a non-toxic substance, it is also often used as antifreeze in food processing systems and in water pipes.[2]

 

 

Electronic cigarettes

Along with vegetable glycerin, propylene glycol is a major component in e-cigarette liquids. Propylene glycol is converted into tiny droplets by e-cigarettes, and acts as a carrier for nicotine and flavorings that are added to some types of these liquids.[2]
