Logwood Extract (Haematein)
Molecular Formula: C16H12O6
Molecular Weight: 300.26
Lauryl hydroxysulfonyl betaine is an excellent amphoteric surfactant, usually a light yellow transparent liquid with a pH value of 6.0-8.0 and a density of approximately 1.1 (at 20℃). It has good water solubility, with a water solubility of 680g/L at 20℃.
Product Usage
Logwood Extract, derived from the heartwood of Haematoxylum campechianum, is a historic natural dye that remains indispensable in both biomedicine and industrial dyeing. In histology, its oxidized form, Haematein, is a crucial component of the H&E stain (Hematoxylin and Eosin), used to stain cell nuclei deep blue for pathological diagnosis—the gold standard in medical labs. In the textile and leather industries, it serves as a premium natural dyestuff that, when combined with different mordants, produces deep, light-fast shades of black, purple, and blue on silk, wool, cotton, and leather. Additionally, its eco-friendly nature makes it a popular choice for high-end natural inks and botanical hair dyes in the personal care sector.
