This was patented and produced in Germany by BASF in 1885 (DRP 34294). The process was first presented in 1887 in Chemische Berichte , the journal of the German Chemical Society . [ 6 ] Although the structure proposed by Ziegler was not confirmed, he was able to develop an alternative synthesis of tartrazine based on the idea that a hydrazone ...
Dog anatomy comprises the anatomical study of the visible parts of the body of a domestic dog. Details of structures vary tremendously from breed to breed, more than in any other animal species, wild or domesticated, [ 1 ] as dogs are highly variable in height and weight.

The dye is a food colouring called tartrazine, used it for its yellowish colour. But that same colour means that it absorbs light, especially blue and ultraviolet light.
A Tsáchila man, with his hair coloured with annatto. The annatto tree B. orellana is believed to originate in tropical regions from Mexico to Brazil. [1] [5] It was probably not initially used as a food additive, but for other purposes, such as ritual and decorative body painting (still an important tradition in many Brazilian native tribes, such as the Wari'); sunscreen; insect repellent ...
Brilliant blue FCF is a synthetic dye produced by the condensation of 2-formylbenzenesulfonic acid and the appropriate aniline followed by oxidation. [4] 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.
In 2008, the Food Standards Agency of the UK called for food manufacturers to voluntarily stop using six food additive colours, tartrazine, allura red, ponceau 4R, quinoline yellow WS, sunset yellow and carmoisine (dubbed the "Southampton 6") by 2009, [14] and provided a document to assist in replacing the colors with other colors.
