Choline

Choline is a ubiquitous water soluble nutrient, often associated with the B vitamins. (In Vitro) :Choline hydroxide can be used as the standard alkaline, and (0.5 M) results pHo shifts rapidly to 7.59 in a sucrose medium (pH at 7.08) .Choline hydroxide (0.1-0.5 g/mL), together with organic carboxylic acids, makes preparation of ionic liquids, which is used for prepare a ionic liquid-reverse micelle drug-carrying delivery system and involves in epidermal desensitization research.
