Embodiment 1

[0041] Chestnut shell extract, its preparation method: the temperature is 80°C, the ultrasonic extraction time is 1h, the pH value is 9, the extraction solid-liquid ratio is 1:15, and the extraction agent is water.

[0042] Chestnut shell removal → ultrasonic extraction of extractant → filtration → filtrate → combined filtrate → concentration → spray drying (inlet temperature 130°C, outlet temperature 70°C) → crude pigment.

Embodiment 2

[0044] Chestnut shell extract, its preparation method: the temperature is 80°C, the ultrasonic extraction time is 2h, the pH value is 9, the extraction solid-liquid ratio is 1:10, and the extraction agent is water.

[0045] Chestnut shell removal → ultrasonic extraction of extractant → filtration → filtrate → combined filtrate → concentration → spray drying (inlet temperature 170°C, outlet temperature 90°C) → crude pigment.

Embodiment 3

[0047] Chestnut shell extract, its preparation method: the temperature is 80°C, the ultrasonic extraction time is 3h, the pH value is 9, the extraction solid-liquid ratio is 1:15, and the extraction agent is water.

[0048] Chestnut shell removal → ultrasonic extraction of extractant → filtration → filtrate → combined filtrate → concentration → spray drying (inlet temperature 150°C, outlet temperature 80°C) → crude pigment.

Abstract

The invention provides a chestnut shell hair colorant which comprises a treating agent and a coloring agent. The treating agent comprises 2-15% of histidine, 1-5% of thickening agents, 5-10% of surface active agents, and the balance deionized water, and the pH of the treating agent is adjusted to be 8-9. The coloring agent comprises 10-30% of chestnut shell extractives, 3-10% of rear-earth salt mordanting active agents, 1.5-5 % of thickening agents, 5-10% of surface active agents, and the balance deionized water. The method for coloring hair by means of the chestnut shell hair colorant comprises the steps of evenly smearing the treating agent on the hair, cleaning the hair after the infrared heating, adding the chestnut shell extractives into the deionized water, adopting ultrasonic treatment, after disaggregation and even scattering of the chestnut shell extractives, adding the other components to be mixed into paste, evenly smearing the paste on the hair, conducting the infrared heating, and if a user needs the deeper color, repeatedly conducting the step two, wherein the color of the obtained dyed hair can be deepened as time passes. The chestnut shell hair colorant is safe, non-toxic, stable in color and high in coloring rate.

Description

technical field [0001] The invention belongs to the field of hair dyes, in particular to natural vegetable hair dyes. Background technique [0002] Chestnut, also known as chestnut and Chinese chestnut, is a plant of the genus Chestnut in the family Fagaceae. It is very rich in nutritional value and sweet and fragrant. It is a common health food. Chestnut is rich in minerals such as starch, protein, vitamins, calcium, phosphorus, and potassium. Traditional Chinese medicine believes that chestnut is sweet and warm, non-toxic, and has the medical effects of invigorating the spleen, nourishing the liver, strengthening the body and strengthening the bones. And chestnut processing will produce a lot of chestnut shell waste. Chestnut shells are rich in natural dyes and a certain amount of tannins, and chestnut shell pigments have biological activities such as antibacterial and anti-oxidation, which have good prospects in printing and dyeing and food. [0003] Hair dyeing is a w...
