⏱ 1 min read
⚡ Quick answer: Second or third on the ingredient list of roughly half the Korean toners you own, and almost nobody knows what it is. Butylene glycol does two dull jobs at once: it holds a little water, and it dissolves things that water alone cannot. The internet panic about it is borrowed from propylene glycol arguments and does not transfer well.
