Pure Logwood extract

SCRD

Description :
Source :
The Logwood tree is small (10 to 15 meters). It has a twisted trunk and a brown-grey bark. The branches are thorny and have very small leaves. The flowers bearing 5 petals, appear in yellow clusters. The wood is very dense and doesn’t float.
Logwood has been used as a dye for centuries.
SCRD has its own Logwood plantation in Southern Nicaragua, since 2005.

Our pure extract comes from the heartwood of Logwood, produced by a clean aqueous extraction. This powder-form extract is mainly rich in hematoxyline, the non-oxydzied form of its main colouring compound. This molecule is widely used as reagent in Biology.

Logwood has been used for centuries as a natural source of dye, and still remains the best source of Haematoxylin, which is used in histology for staining. In its time, logwood was considered a versatile dye, and was widely used on textiles but also for paper and leather.
Pure Logwood extract dyes water in pink-purple. The dye's colour depends on the mordant used as well as the pH. It is reddish in an acid environment but bluish in an alkaline one.
