Chlorophyllin refers to any one of a group of closely related water-soluble salts that are semi-synthetic derivatives of chlorophyll, differing in the identity of the cations associated with the anion. Its most common form is a sodium/copper derivative used as a food additive and in alternative medicine. As a food coloring agent, copper complex chlorophyllin is known as natural green 3 and has the E number E141.[1]


Alternative medicine[edit]

Chlorophyllin is the active ingredient in a number of internally taken preparations[medical citation needed] intended to reduce odors associated with incontinence, colostomies, and similar procedures, as well as body odor in general. It is also available as a topical preparation, purportedly useful for both treatment and odor control of wounds, injuries, radiation burns, and other skin conditions."Chlorophyllin Uses, Side Effects & Warnings". Retrieved 2020-03-29. Chlorophyllin has been used in alternative medicine as an aid to reduce the odor of urine or feces (bowel movements).

3D printing[edit]

Chlorophyllin has been used as a biocompatible photoblocker for generating green colored hydrogels with complex inner structures.[2]

Chemical properties[edit]

Chlorophyllin is water-soluble. In vitro, it binds to some environmental mutagens such as the polycyclic aromatic hydrocarbons benzo[a]pyrene[3] and dibenzo[a,i]pyrene.[4] Chlorophyllin also binds to acridine orange.[5]
