Brilliant Blue FCF (Blue 1), also known under commercial names, is a colorant for foods and other substances to induce a color change. It is denoted by E number E133 and has a color index of 42090. It has the appearance of a reddish-blue powder. It is soluble in water, and the solution has a maximum absorption at about 628 nanometer.

Chemistry [edit]
It is a synthetic dye produced using aromatic hydrocarbons from petroleum.[1] It can be combined with tartrazine (E102) to produce various shades of green.
It is usually a disodium salt. The diammonium salt has CAS number []. Calcium and potassium salts are also permitted. It can also appear as an aluminium lake. The chemical formation is C37H34N2Na2O9S3. The dye is poorly absorbed from the gastro-intestinal tract and 95% of the ingested dye can be found in the feces. It also reacts with certain bile pigments to form green feces.[citation needed]
Applications [edit]
As a blue color, Brilliant Blue FCF is often found in ice cream, canned processed peas, packet soups, bottled food colorings, icings, ice pops, blue raspberry flavored products, dairy products, sweets[2] and drinks, especially the liqueur blue curacao. It is also used in soaps, shampoos, mouthwash[3] and other hygiene and cosmetics applications. In soil science, Brilliant Blue is applied in tracing studies to visualize infiltration and water distribution in the soil.
Health and safety [edit]
Brilliant Blue FCF has previously been banned in Austria, Belgium, Denmark, France, Germany, Greece, Italy, Spain, Sweden, and Switzerland among others[4] but has been certified as a safe food additive in the EU and is today legal in most of the countries. It has the capacity for inducing an allergic reaction in individuals with pre-existing moderate asthma.[5]
Biomedical research [edit]
Scientists who were investigating the use of compounds to lessen the severity of inflammation following spinal cord injury had previously tested a compound called OxATP to block a key ATP receptor in spinal neurons. However, OxATP has toxic side effects and must be injected directly into the spinal cord; in searching for alternatives they noted that Brilliant Blue FCF has a similar structure. This led them to test a related dye, Brilliant Blue G (also known as Coomassie Brilliant Blue) in rats, which improved recovery from spinal cord injury.[6]
