Dihydroxyindole powder Introduction

Dihydroxyindole powder is an important intermediate of melanin, first discovered in a plant species in nature. It is the second isomer of 1,2-dihydroxyindole, and pure 5,6-dihydroxyindole is soluble in hot water and stable in a crystalline state. However, in slightly alkaline solutions, it quickly oxidizes into substances similar to melanin. 5,6-Dihydroxyindole is a non-toxic and side effect permanent hair dye that is gradually replacing aniline compounds as the best choice for synthetic hair dyes. Our Dihydroxyindole powder has a good effect on hair dye, preservatives, and antioxidants, and is a high-quality raw material for product production.

Main applications

Dihydroxyindole powder is an important precursor of melanin and has a wide range of applications. Hair dye is its main application field. As a permanent hair dye, Dihydroxyindole has the same hair dyeing mechanism as p-Phenylenediamine and its derivatives. It acts on hair keratin fibers, making the dyeing effect very obvious. It enters the interior of the hair pulp, and after dyeing, it is not easy to fade after washing and is not greatly affected by sunlight. In addition, Dihydroxyindole is produced by the organism itself and is non-toxic and has no side effects on the body. It is an effective substitute for p-Phenylenediamine hair dyes with certain toxicity. In addition, it also has important applications in the fields of preservatives, antioxidants, and so on.
Due to the high hydroxyl activity during the synthesis of Dihydroxyindole, which is difficult to control, the synthesis environment for this product is demanding, and the product yield is very low. Although there are artificial synthesis methods for Dihydroxyindole in the world, these methods can be used for research and production, but they cannot be applied to large-scale industrial production yet.

FAQ

Q1:What is the dyeing principle of Dihydroxyindole powder?

A1:Dihydroxyindole powder enters the entrance of the epidermal scale layer as a small molecule of melanin precursor, which can quickly diffuse into the hair cortex. With the help of oxidants, 5,6-dihydroxyindole can be converted into melanin macromolecules, making the hair dyeing effect more long-lasting.

Q2:How many methods are there for synthesizing Dihydroxyindole powder?

A2:At present, Dihydroxyindole powder is generally synthesized through methods such as hydroxyl protection, nitration, deprotection, and cyclization, with the Benzaldehyde method being the most commonly used.

Q3:Is Dihydroxyindole aqueous solution acidic or alkaline?

A3:The aqueous solution undergoes an acidic reaction and turns blue when it encounters ferric chloride.
