Product Description

Indigo

Indigo is an organic synthetic dye, also known as indigo pigment or Blue No. 3.
Indigo pigments are one of the oldest pigments known to man and are widely used in food, medicine and printing and dyeing industries. The use of indigo as a fabric dye dates back to at least 2500 BC. Some clothes worn by ancient Egyptian mummies and blue hemp fabrics unearthed in Mawangdui in China are dyed by indigo, and a Yao group in China is named "LAN Yingyao" because of its unique technology of producing and using indigo dyeing cloth. In the food industry, indigo is used as food coloring in its sodium sulfonate salt or its aluminized form, which is called "bright blue" and bright blue aluminum lake in China. In the United States, it is mainly in the form of sodium sulfonate, which is called "indigo".
