Embodiment 1

[0046] 0.34g gallic acid was dissolved in 17.83mL solvent to obtain gallic acid solution; 1.19gFeCl 2 4H 2 O and 1.08 g FeCl 3 ·6H 2 O was dissolved in 17.83mL solvent to obtain an iron-containing solution; after mixing the gallic acid solution and the iron-containing solution, the pH was adjusted to 5 with 0.1mol / L hydrochloric acid, and left to stand for 30min to obtain a mixed solution; 0.1g white hair Soak in the mixed solution for 30 minutes to dye hair, take out the hair and dry it in an oven at 50°C for 30 minutes, wash it with water and blow dry it completely with a hair dryer to obtain dyed hair; the solvents are distilled water, ethanol and ethylene glycol, distilled water, ethanol And ethylene glycol volume ratio=26.16:6:3.5, Fe(II):Fe(III) molar ratio=1.5:1. Measure the L*, a*, and b* values ​​of the dyed hair with a computer colorimeter, test 3 times, record them as the first time, the second time, and the third time respectively, and calculate the average valu...

Embodiment 2

[0051] 0.34g gallic acid was dissolved in 17.83mL solvent to obtain gallic acid solution; 1.584gFeCl 2 4H 2 O and 0.54 g FeCl 3 ·6H 2 O was dissolved in 17.83mL solvent to obtain an iron-containing solution; after the gallic acid solution and the iron-containing solution were mixed, the pH was adjusted to 5 with 0.5mol / L sodium bicarbonate, and left to stand for 30min to obtain a mixed solution; 0.1g Soak the white hair in the mixed solution for 30 minutes to dye the hair. Take the hair out and dry it in an oven at 50°C for 30 minutes. After washing with water, dry it completely with a hair dryer to obtain dyed hair. The solvents are distilled water, ethanol and ethylene glycol, and distilled water , ethanol and ethylene glycol volume ratio=26.16:6:3.5, Fe(II):Fe(III) molar ratio=4:1. Measure the L*, a*, and b* values ​​of the dyed hair with a computer colorimeter, test 3 times, record them as the first time, the second time, and the third time respectively, and calculate t...

Embodiment 3

[0055] Dissolve 0.17g of gallic acid in 18.33mL of distilled water, adjust the pH to 5 with 0.1mol / L sulfuric acid to obtain a gallic acid solution; stir and mix 0.125g of Tween 80, 0.125g of AEO, 0.25g of water-soluble azone and 17mL of distilled water After that, add 0.943g FeCl 2 4H 2 O and 0.064g FeCl 3 ·6H 2 O is dissolved and stirred until dissolved, and the pH is adjusted to 5 with aqueous sodium hydroxide solution to obtain an iron-containing mixed solution; after the gallic acid solution and the iron-containing solution are mixed, the pH is adjusted to 5 with 0.5mol / L sodium bicarbonate, and left standing After 30 minutes, a mixed solution was obtained; 0.2 g of white hair was soaked in the mixed solution for 30 minutes, the hair was taken out, dried in a 50°C oven for 30 minutes, washed with water, and then completely dried with a hair dryer to obtain dyed hair; wherein, Fe(II ): Fe(III) molar ratio=20:1. Measure the L*, a*, and b* values ​​of the dyed hair with ...

Abstract

The invention provides a gallic acid hair dye and a using method thereof, belonging to the technical field of hair dyes. The gallic acid hair dye provided by the invention includes independently packaged gallic acid and iron-containing reagents; the molar ratio of the total amount of iron in the gallic acid and iron-containing reagents is 1: (2-10); the iron-containing reagents include iron reagents and Fe(II) reagent, calculated as Fe(III) and Fe(II) respectively, the molar ratio of the iron reagent and Fe(II) reagent is 1:(1.5-100). In the gallic acid hair dye provided by the present invention, ferrous ions and ferric ions are in dynamic equilibrium at a certain pH value, and the concentration and existence state of Fe(II) in the solution can be suppressed to a certain extent by introducing Fe(III) , causing some gallic acid molecules to fail to interact with Fe(II), so that the color of the dyed hair can be adjusted, and the hair can be changed from blue-black to golden yellow.

Description

technical field [0001] The invention relates to the technical field of hair dyes, in particular to a gallic acid hair dye and a using method thereof. Background technique [0002] Gallic acid, an endogenous polyphenol, widely exists in tea, grapes, berries, oak and chestnut, etc., does not cause contact allergies, and has effects on ribonucleotide reductase, UGDH, Bax / Bcl- 2. The specific effect of NF-B and other signaling pathways has anti-cancer effects, plays an important role in the field of drug research, and has great potential in pharmaceutical, cosmetic and other industries. [0003] At present, there are many reports on the application of gallic acid in the field of hair dyes. The dyeing principle is mainly that gallic acid is complexed with ferrous ions or iron ions to form a network structure and then coated on the hair surface, thereby achieving the purpose of hair dyeing. However, the color after the action of gallic acid and iron ions is dark blue with a singl...
