The origin and properties of Alizarol
Alizarol, also known as alizarin, is a red dye obtained from the root of the madder plant (Rubia tinctorum). This plant was already used in ancient Egypt, Greece, and Rome for dyeing textiles. The red dye alizarin is one of the oldest known natural dyes of humanity.
Alizarol is characterized by its intense red coloration, which can range from a strong red to a dark purple. The hue depends on various factors, such as the pH of the dye bath. Alizarol is insoluble in water but can be introduced into textiles using alkaline solutions or with the help of mordants.
In addition to its use as a dye, Alizarol also possesses other interesting properties. For example, it acts antimicrobial and can therefore also be used in cosmetic products. Furthermore, Alizarol shows high lightfastness, making it attractive for many applications.
