It is usually supplied as its red sodium salt, but can also be used as the calcium and potassium salts. These salts are soluble in water. In solution, its maximum absorbance lies at about 504 nm.:921
Use as food colorEdit
Allura Red AC is a popular dye throughout the world. Annual production in 1980 was greater than 2.3 million kilograms.
The European Union approves Allura Red AC as a food colorant, but EU countries' local laws banning food colorants are preserved. In the United States of America, Allura Red AC is approved by the FDA for use in cosmetics, drugs, and food. When prepared as a lake it is disclosed as Red 40 Lake or Red 40 Aluminum Lake. It is used in some tattoo inks and is used in many products, such as soft drinks, cherry flavored products, children's medications, and cotton candy. It is by far the most commonly used red dye in the United States, completely replacing amaranth (Red 2) and also replacing erythrosine (Red 3) in most applications due to the negative health effects of those two dyes.
Studies on safetyEdit
Allura Red has been heavily studied by food safety groups in North America and Europe, and remains in wide use.
The UK FSA commissioned a study of six food dyes (tartrazine, Allura red, Ponceau 4R, quinoline yellow WS, sunset yellow, carmoisine (dubbed the "Southampton 6")), and sodium benzoate (a preservative) on children in the general population, who consumed them in beverages. The study found "a possible link between the consumption of these artificial colours and a sodium benzoate preservative and increased hyperactivity" in the children; the advisory committee to the FSA that evaluated the study also determined that because of study limitations, the results could not be extrapolated to the general population, and further testing was recommended.
The European regulatory community, with a stronger emphasis on the precautionary principle, required labelling and temporarily reduced the acceptable daily intake (ADI) for the food colorings; the UK FSA called for voluntary withdrawal of the colorings by food manufacturers. However, in 2009 the EFSA re-evaluated the data at hand and determined that "the available scientific evidence does not substantiate a link between the color additives and behavioral effects" and in 2014 after further review of the data, the EFSA restored the prior ADI levels. In 2015, the EFSA found that the exposure estimates did not exceed the ADI of 7 mg/kg per day in any population.
The US FDA did not make changes following the publication of the Southampton study, but following a citizen petition filed by the Center for Science in the Public Interest in 2008, requesting the FDA ban several food additives, the FDA commenced a review of the available evidence, and still made no changes.
Allura Red AC was at one time banned in Denmark, Belgium, France, and Switzerland, and was also banned in Sweden until the country joined the European Union in 1994.[not in citation given] In Norway, and Iceland, it was banned between 1978 and 2001, a period in which azo dyes were only legally used in alcoholic beverages and some fish products.
