Alternative applications of propylene glycol in daily chemicals

October 21,2023

Propylene glycol(PG) is a colorless, odorless, sweet-tasting organic compound. Due to its unique physical and chemical properties, it is widely used in the daily chemical industry.

In this article, we will discuss some of the most common uses of propylene glycol in the cosmetic industry.

Personal care products

Propylene glycol is widely used in personal care products such as lotions, creams, and hair care products. It acts as a humectant, which means it helps retain moisture in the skin and hair. It also acts as a solvent to help dissolve other ingredients in the product. Additionally, propylene glycol has low toxicity and is non-irritating, making it a safe ingredient in personal care products.



In cosmetics, propylene glycol is commonly used as a solvent and emulsifier. It helps dissolve and mix other ingredients in the product and also helps stabilize the formula. Additionally, propylene glycol helps enhance the penetration of other active ingredients into the skin. This makes it a popular ingredient in anti-aging and skin-whitening products.


Propylene glycol is also commonly used as a solvent and carrier for fragrances. It helps dissolve essential oils and disperse them evenly throughout the product. Propylene glycol is also a common ingredient in perfumes and colognes, where it helps stabilize fragrance and prevent it from breaking down over time.


Propylene glycol is a common ingredient in electronic cigarette (e-cigarette) liquids. It serves as a carrier for nicotine and flavorings, helping to create the vapor that the user inhales. While the safety of e-cigarettes is still being studied, propylene glycol has been shown to be safe for use in e-cigarettes when used in moderate amounts.


Propylene glycol is also used as an antifreeze in heating and cooling systems and in the automotive industry. It is used as a safer alternative to ethylene glycol, which is toxic and can be harmful if ingested. Propylene glycol is less toxic and biodegradable, making it a safer choice for antifreeze applications.

Detergents and cleaners

Propylene glycol is used as a solvent and surfactant in many cleaning products. It helps dissolve dirt and grime and also helps emulsify and suspend dirt for easy removal. Propylene glycol is also used in some laundry detergents to help dissolve active ingredients and increase the effectiveness of the product.
