Dipropylene Glycol
What is Dipropylene Glycol?
Dipropylene Glycol is a type of glycol, a derivative of propane, commonly used in industrial and consumer products. It is typically produced by the hydration of propylene oxide.
In personal care products like deodorants and fragrances, Dipropylene Glycol acts as a solvent and carrier for fragrances, helping to blend fragrant oils into the product base uniformly. Dipropylene Glycol is generally considered safe for use in these applications when used in regulated amounts.
When spotting Dipropylene Glycol on a label, it’s noteworthy for its role primarily as a solvent rather than any direct health effects. However, some may have sensitivity to glycols.
