Lawsone [CAS: 83-72-7] (CI Natural Orange 6; CI 75420), also known as henna and isojuglone, occurs in the shrub henna (Lawsone alba). In England, the plant is known as Egyptian privet. The dye was extracted from the leaves of the plant, using sodium bicarbonate, and the extracts used to dye protein fibers an orange shade. Henna is probably the oldest cosmetic known. The ancient Egyptians used it as a hair dye and for staining fingernails. It is said that Mohammed dyed his beard with henna. Lawsone has been identified as 2-hydroxy-1,4-naphthoquinone. It has been synthesized by the Thiele acetylation of 1,4-naphthoquinone followed by hydrolysis and oxidation.


2-Hydroxy-1,4-naphthoquinone(HNQ) is the principal natural dye ingredient contained at 1.0-1.4% in the leaves of Henna (Lawsonia inermis). It is an ancient red-orange dye. Henna has been used for more than 4000 years not only as a hair dye, but also as a body paint and tattoo dye. Today, semi-permanent hair dyes containing Henna as well as its pure dye ingredient HNQ are widely used and have become increasingly popular due to their natural origin.


2-Hydroxy-1,4-naphthoquinone is used for preparing decorative hair and skin dyes. 2-Hydroxy-1,4-naphthoquinone also demonstrates antimicrobial and antioxidant effects. It also suppress the formation of hydrogen peroxide and superoxide radical anion by aldehyde oxidase-catalyzed reactions.
