Butoxydiglycol

What is Butoxydiglycol?

Butoxydiglycol, chemically known as 2-(2-butoxyethoxy)ethanol, is a synthetic glycol ether produced through the reaction of ethylene oxide with butanol. This clear, low-odor liquid belongs to the category of cosmetic solvents commonly used in fragranced products, cleansers, and nail formulations. It functions by dissolving lipophilic and hydrophilic substances that do not mix easily in water or oil bases, enabling stable emulsions. Additionally, it modulates product thickness for optimal spreadability and application feel, while facilitating the even dispersion of scents to provide a consistent sensory profile without overpowering base notes.
