The Info List - Chlorobutanol



Chlorobutanol (trichloro-2-methyl-2-propanol) 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.

Appearance

In pure state it is a white, volatile solid with a menthol-like odor.

Chemical synthesis

Chlorobutanol is formed by the simple nucleophilic addition of chloroform and acetone. The reaction is base driven by potassium or sodium hydroxide.

Toxicity

Chlorobutanol is highly toxic to the liver, is a skin irritant and a severe eye irritant.[1]

Parthenogenesis

Chlorobutanol has proven effective at stimulating parthenogenesis in sea urchin eggs up to the pluteus stage, possibly by increasing irritability to cause stimulation. For the eggs of the fish Oryzias latipes, however, chlorobutanol only acted as an anesthetic.[2]
