Dipropylene Glycol (DPG) is a colorless, odorless, and hygroscopic (water-absorbing) liquid that is commonly used as a solvent, humectant, and carrier in a variety of personal care, cosmetic, and fragrance products. It is a member of the glycol family and is derived from propylene oxide, a byproduct of petroleum. Key Uses and Benefits: Fragrance Carrier: DPG is widely used in perfumes and scented products to help dissolve and dilute fragrances, making them easier to apply. It helps extend the longevity of the fragrance by allowing it to slowly evaporate over time. Humectant: As a humectant, DPG draws moisture from the environment into the skin, which helps to maintain hydration. This property makes it a common ingredient in moisturizers and skincare products. Solvent: DPG acts as a solvent in various formulations, effectively dissolving active ingredients or compounds that may not otherwise be easily mixed into products like lotions, creams, or shampoos.
