Some Quick Facts About Indigo
- Originally used through indigo plants, was a natural dye used as early as Ancient Egyptian times, when indigo dye was used to dye cloths for mummification.
- Synthetic dye first synthesized in 1880 by J. F. W. Adolph von Bayer. He later won a Nobel Prize for his work with synthetic dyes.
- In 2004, a system was invented for synthetic indigo to be freeze dried into crystal form and reactivated so it could be sold and reactivated into dye with water for home use.
- In 2002, 17,000 tons of synthetic indigo were produced worldwide.
Properties of Synthetic Indigo
- Known for its vibrant, blue-purple color.
- Soluble in water.
- Forms a mechanical bond when it dyes fiber, not a chemical one.
- Melting Point: 390°-392°C
- Mild oxidation allows indoxyl to be converted to indigo
- Low toxicity, with an LD50 (or lethal concentration of 50%) of 5000mg/kg
- Reacts easily with sulfuric acid to convert pure synthetic indigo into a derivative called indigo carmine, which is used for cosmetics and pharmaceuticals.
