BUTYLENE GLYCOL

Safety grade: A

Butylene glycol is a clear, colorless liquid that acts like a humidifier for your skin, drawing moisture from the air and deeper skin layers to keep the surface hydrated. It's commonly used in skincare and cosmetics because it helps products feel lighter while still being effective.

This ingredient hydrates and conditions skin by attracting and retaining moisture, while also helping dissolve other ingredients, improving product texture, and masking any unpleasant odors from other components.
