Butylene Glycol

What is Butylene Glycol?

Butylene glycol is like the smoother, more sophisticated cousin in the glycol family—a multitasking ingredient that hydrates while improving product texture and stability. This clear liquid works as both a humectant drawing moisture to the skin and a solvent helping to dissolve other ingredients. Think of it as a skilled social coordinator bringing together water-loving and oil-loving components that wouldn't normally mix. It's the skincare equivalent of that perfectly balanced cocktail—lightweight yet effective, with a silky texture that disappears into skin without residue. For those who want hydration without heaviness, butylene glycol delivers that perfect slip and hydration boost while helping other active ingredients penetrate more effectively, making it a staple in everything from K-beauty essences to clinical serums.
