Amaranth

Amaranth (CAS 915-67-3), also known as E123 and Red No. 2, is a synthetic azo dye producing a deep red-to-maroon hue across a range of industrial and food applications.

It functions as a colorant in formulations where consistent, stable red coloration is required at controlled concentrations. In the textile and leather industries, it is used to dye natural and synthetic fibers.

The dye delivers uniform color uptake in batch and continuous dyeing processes. Ink formulators incorporate it into printing inks for packaging applications where vivid red shades and dye solubility are process requirements.

In food and beverage manufacturing, where permitted by regional regulation, it colors products such as caviar, certain alcoholic drinks, and fish roe. Paper manufacturers use it to achieve consistent red tones.

The product is utilized in decorative and specialty paper grades to ensure visual uniformity. Amaranth is supplied as a fine dark red to brown powder for various industrial and commercial manufacturing needs.

It is available in food-grade specification meeting E123 purity standards, as well as technical grade for textile and industrial use. Dye content is a key specification buyers should confirm during procurement.

Commercial grades typically vary in active dye concentration depending on the intended application. This versatility makes it a staple for manufacturers requiring reliable red pigmentation in diverse chemical environments.
