Butylene glycol is a colorless, odorless organic compound that belongs to the glycol family. It is a type of diol, which means it contains two hydroxyl groups (-OH) that contribute to its properties as a solvent and humectant. Butylene glycol is typically derived from petroleum and is produced through the hydration of butylene oxide. Its chemical structure allows it to mix well with both water and oil, making it versatile for various applications.
