Introduction to 1, 2-pentanediol

1, 2-pentanediol is a diol (* 1) with refreshing feeling and excellent antibacterial properties, and also alkanediol, a polyol with high antibacterial properties.

* 1 polyols have extremely high hygroscopic and water-retaining properties, so they are the most commonly used moisturizers in cosmetics. The name “alcohol” is misleading, but ordinary alcohol (ethanol) is a mono alcohol, and polyols and mono alcohols (ethanol) are different substances.
