Problems solved by technology

North American black walnut exocarp extract contains a variety of natural black dyes and tannin that can be used as a mordant. It is a very good natural black dye; although it does not need to add more ferric sulfate or ferrous iron like other natural dyes As a dyeing agent, it will be more uniform than the above dyes, but not uniform enough

Abstract

The invention discloses a hair dye prepared by extracting liquid of North American black walnut exocarp and a preparation method thereof, including a dye and a stabilizer. The dye is Gandhi Gum. The dye and the leveling agent Gandhi Gum in the hair dye of the present invention are edible natural ingredients extracted from natural fruit peels and plants, and are non-toxic and harmless. The hair dye of the present invention does not contain chemically synthesized dyes. High dyeing rate, uniform, natural black color after dyeing, good gloss, washable, light fast, safer and less toxic than chemical synthetic dye hair dye, it is an ecological hair dye.

Description

technical field [0001] The invention belongs to the field of fine chemical industry. More specifically, the present invention relates to a natural black hair dye prepared from the exocarp extract of North American black walnut (Juglansnigra). Background technique [0002] At present, most of the hair dyes on the market are permanent hair dyes containing ammonia. The main dyeing intermediates include p-phenylenediamine, p-aminophenol, o-phenylenediamine, etc. These hair dyes have certain allergenic and carcinogenic properties. possibility. And these oxidative hair dyes tend to have an embarrassing, uneven yellow tint when they fade. There are also some natural hair dyes on the market. As some current patents provide, they generally use tannin (tannin), hematoxylin or curcumin as the main component of the dye after reacting with ferric sulfate or ferrous iron. The iron salt produced is a black dye, and the degree and unevenness of the reaction directly affect the hair dyein...
