Butoxyethanol
What Butoxyethanol is & what it does
Butoxyethanol (ethylene glycol monobutyl ether) is a glycol-ether solvent. In cosmetics it is used mainly as a solvent and coupling agent that helps dissolve and blend ingredients that do not mix easily, and it is more common in cleaning-type or specialty formulas than in leave-on skincare. It evaporates moderately and aids an even, streak-free finish. Its role is functional rather than skin-conditioning.
