What is Acid Red 18?

Acid Red 18, also known as Acid Red 18 or C.I. 16255, is a synthetic azo acid dye. Its chemical formula indicates that it contains complex nitrogen and sulfonic acid groups, properties that allow it to dissolve under specific conditions and be used in dyeing processes. The dye is mainly used in industry and certain commercial applications, such as dyeing textiles, leather, paper, and some plastics or resins.

Its characteristics include good light resistance and acid resistance, especially stability to citric acid and tartaric acid, but it will turn brown in an alkaline environment. The absorption wavelength of Acid Red 18 is about 508 nanometers ± 2 nanometers, which means that under a specific spectrum, it can strongly absorb light and show its bright red color.

In addition, although it is sometimes listed as a food additive (such as E124), its use in the food industry may be restricted or prohibited due to safety concerns, depending on the regulations of different countries and regions. In the pharmaceutical field, it may be used as an intermediate. It needs to be sealed and placed in a cool and dry place when stored to maintain its stability and performance.
