Introduction: 5, 6-dihydroxyindole has non-toxic, side effects of permanent hair dye, is gradually replacing a-niline compounds as the best choice for synthetic hair dye.
Application: 5, 6-dihydroxyindole is an important intermediate of melanogen, which was first found in a plant in nature.
Hair dyeing mechanism: As a permanent hair dye, 5, 6-dihydroxyindole and p- phenylenediamine and its derivatives have the same hair dyeing mechanism, which acts on the keratin fiber of hair, making the dyeing effect very obvious. It enters the interior of the hair pulp, and is not easy to fade after dyeing, nor is it greatly affected by sunlight. For a long time, the effective blackening ingredients in hair dye are p- phenylenediamine and its derivatives, which have carcinogenic, teratogenic and allergic effects on human body and affect the health of users. As an effective substitute, 5, 6-dihydroxyindole is produced by the organism itself, which is non-toxic to the body and has side effects.
Chemical properties: 5, 6-dihydroxyindole is the second isomer of dihydroxyindole, pure 5, 6-dihydroxyindole soluble in hot water, insoluble in petroleum ether, crystal state is very stable, but in a slightly alkaline solution is quickly oxidized into melanin-like substances.
