Chlorobutanol

Chlorobutanol (trichloro-2-methyl-2-propanol) is an organic compound with the formula CCl3C(OH)(CH3)2. The compound is an example of a chlorohydrin. The compound is a preservative, sedative, hypnotic and weak local anesthetic similar in nature to chloral hydrate. It has antibacterial and antifungal properties. Chlorobutanol is typically used at a concentration of 0.5% where it lends long term stability to multi-ingredient formulations. However, it retains antimicrobial activity at 0.05% in water.
