5,6-Dihydroxyindole is an important intermediate in melanin production. Melanin is formed from tyrosine in the body through a series of enzymatic oxidation reactions. One of the most important intermediates in this process is 5,6-dihydroxyindole. This substance is naturally occurring in the body, making it non-toxic, with few side effects, and avoiding the carcinogenic, teratogenic, and allergenic effects of hair dyes made from p-phenylenediamine and its derivatives. 5,6-Dihydroxyindole has a small molecular weight and, as a permanent hair dye, operates on the same mechanism as other dyes: it penetrates the hair shaft and undergoes oxidative polymerization to form a colored macromolecule that is then fixed in place. Currently, it is being used in some personal care products to replace aniline and phenolic compounds.

For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
