Synthetic colorants are those created in a laboratory or industrial setting. The production and improvement of colorants was a driver of the early synthetic chemical industry, in fact many of today's largest chemical producers started as dye-works in the late 19th or early 20th centuries, including Bayer AG (1863).

Mauveine is a mixture of four related aromatic compounds differing in number and placement of methyl groups.Its organic synthesis involves dissolving aniline, p-toluidine, and o-toluidine in sulfuric acid and water in a roughly 1:1:2 ratio, then adding potassium dichromate.
Jean-Baptiste Guimet (20 July 1795 – 8 April 1871), French industrial chemist, and inventor of synthetic colors, [2] was born at Voiron, Isère. He studied at the École Polytechnique in Paris , and in 1817 entered the Administration des Poudres et Salpêtres. [ 3 ]
The first synthetic dye, mauve, was discovered serendipitously by William Henry Perkin in 1856. [11] [12] [13] The discovery of mauveine started a surge in synthetic dyes and in organic chemistry in general. Other aniline dyes followed, such as fuchsine, safranine, and induline. Many thousands of synthetic dyes have since been prepared. [14 ...
Ponceau (17th century French for "poppy-coloured") is the generic name for a family of azo dyes. Ponceau 4R is a strawberry red azo dye which can be used in a variety of food products, and is usually synthesized from aromatic hydrocarbons; it is stable to light, heat, and acid but fades in the presence of ascorbic acid.

The FDA may finally move to ban artificial red food dye, the coloring found in beverages, snacks, cereals and candies. ... said it’s been over a decade since the safety of the synthetic color ...
Carmine is a colorant used in the manufacture of artificial flowers, paints, crimson ink, rouge and other cosmetics, and some medications. [10] Synthetic carminic acid is complex and expensive to produce. Therefore, natural cochineal carmine is predominant on the market.
Earlier references to a mauve dye in 1856–1858 referred to a color produced using the semi-synthetic dye murexide or a mixture of natural dyes. [10] Perkin was so successful in marketing his discovery to the dye industry that his 2000 biography by Simon Garfield is simply entitled Mauve. [11] Between 1859 and 1861, mauve became a fashion must ...
