Jaipur pink

Jaipur pink or Sappan wood natural dye extract is produced by solvent extraction method. Sappan wood is known as Indian redwood, or also called as the heartwood of Caesalpinia trees. The heartwood contains different water soluble flavonoids namely, brazilin, protosappanin and haematoxylin. Brazilin is the main flavonoid constituent found in the heartwood, which is well known as the natural red color dye for staining cotton, silk and wool. Under natural condition it mostly grows in hilly areas. The Brazilin gives red pigment to fabrics. In extraction process of Brazilin, the wood is first crushed into powder form and then the powdered bark is boiled with water at high temperature for about 40-45 minute. Then it is filtered and treated with different mordents to give a varied range of strong red dyes, ranging from deep crimsons to pinks.
