Also known under the name CI 73015 (indigotine – indigodisulfonic sodium salt) color or also E132 food blue.
Indigo carmine is generally used as a pH indicator. In a 1% aqueous solution. It is blue at pH 11.4 and yellow at 13.0. Indigo carmine is also a redox indicator (i.e., anytime reversible).
- In the colonoscopy to visualize the tissue change (to the pH 11.4 tissue the indigo is yellow)
- In obstetrics surgery, to locate amniotic fluid leaks
- In urology, to mark areas of the urinary tract (the kidneys filter the dye out of the blood, which quickly colors the urine blue)
- In histology and/or cytology for dyeing tissue samples.The dye can lead to an increase in blood pressure.Indigotine is considered harmless.In a recent study an animal experiment was conducted which found that, indigotin in the presence of sodium nitrite become carcinogenic nitrosamines. Therefore, we recommend not to eat smoked or cured meat before and after the examination. But so far, there are no comparable studies in humans
Surfaces colorant for Endoscopy in the digestive tract
Easy to Use. Indigo Carmin 1 % allows to identify injuries and their dilatations in the mucous membrane of the digestive tract, which allows to determine the quality and accuracy of this study to obtain more accurate biopsy samples.

Indigotine: Health risks
The ADI value of indigotine is 5 mg per kilogram of body weight. The dyestuff indigotine is considered harmless, since it is mostly precipitated undefined. In a study in mice, evidence has shown that indigotine is converted into nitrosamines in the presence of sodium nitrite. Nitrosamines are suspected to have a carcinogenic effect. There are, however, no studies on humans that confirm this indication. Indigotine is generally not used for coloring organic food. The EC eco-regulation excludes the use of artificial food dyes – which serve no other purpose than coloring – with organic food.
